DAYS 1-5 (FEBRUARY 3-7)
There’s a little game tonight that many of you will be interested in, so what will the weather be like for any last minute errands you need to get done before it? The weather will be favorable, just a cloud/sun kind of day, not “warm” yet but certainly warmer than recently. However, you still need to watch for patchy ice on the ground where it had never melted, or had partially melted in re-froze, so keep that in mind so you’re able to watch the game from where you planned, without having to make a visit to the ER first. A frontal boundary sits in the area today, having dropped down from northern New England as a weak cold front last night and will head back north as a warm front today and tonight. This is responsible for some cloudiness but no precipitation. We’ll be in the warm sector Monday and Tuesday, even though a trough passes by in the early hours of Tuesday from the west when there is a rain shower risk, this doesn’t really have any cold air behind it. We’ll have to wait for a cold front to come through in the evening, allowing us to enjoy an early preview of spring. And keep in mind it’s just an early preview. It’ll still be early February and just 3 days beyond the climate mid point of the cold season. We will come back to reality when it is seasonably cold by midweek. We’ll also be watching the approach of a storm system from the west by the end of the period. The current feeling is that the main storm will be heading for the Great Lakes and we’ll be dealing with liquid falling from the sky. The problem may be that there will be cold air trapped at the surface, and this is a recipe for icing for at least some areas. Still a few days to refine the details.
Forecast specifics…
TODAY: Variably cloudy. Highs 35-42. Wind light variable.
TONIGHT: Variably cloudy. Lows 25-32. Wind SW 5-15 MPH.
MONDAY: Partly cloudy. Highs 48-55. Wind SW 10-20 MPH.
MONDAY NIGHT: Mostly cloudy. A period of rain showers before dawn. Lows 41-48. Wind SW 10-20 MPH.
TUESDAY: Variably cloudy with passing rain showers early, then partly cloudy. Highs 55-62. Wind SW to W 10-20 MPH, higher gusts.
WEDNESDAY: Partly sunny. Temperatures fall to the 30s.
THURSDAY: Mostly cloudy. Rain/ice possible by late-day. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 8-12)
The pattern described yesterday with cold air in Canada and a milder ridge of high pressure in the US Southeast will be in place. This will result in some air mass battling, and we’ll likely start and end this period unsettled with storms that favor rain/ice over snow. In between, dry and seasonably cold weather is expected.

DAYS 11-15 (FEBRUARY 13-17)
The same basic pattern should remain in place with unsettled weather again to start and possibly end this period and an interlude of dry and chilly weather in between. Obviously low confidence on timing this far in advance.

8:52AM

DAYS 1-5 (FEBRUARY 2-6)
Well, we got our annual prognostication from Punxutawney Phil this morning. I’m not sure if he favors the GFS or the Euro, but what he did say (in “Groundhogese”) was that he saw no shadow and therefore predicts an early spring. Our regional groundhog, Miss G., from Lincoln MA, will be making her prediction at 10AM, but so as not to be any further influenced by large rodents, the blog update shall be out before we find out what Miss G. has to say. What I have to say is this. We are in the midst of a moderation. It may not feel quite like it yet, as last night was still pretty cold, with some areas falling to near or even below zero. But today, you’ll notice lots of high cloudiness and that’s a sign of warming aloft, which usually means warming at the surface in most cases. This will be one of them. Today’s surface temperature recovery only brings us back to the vicinity of the freezing point, but it’s relatively warm compared to where we sat just 2 days ago. However today will also contain a fair amount of moving air, i.e., it will be breezy, so that will still keep it feeling chilly. Sunday will see less wind, brighter sun, and will moderate further, opening the door to a couple days that will make you think Phil is really onto something early next week, when many areas see temperature easily breaking 50. However, we all know that a couple mild days in early February, no matter how winter has been up to this point, is not a sign to declare an end to winter. Trust me, we’re not done with cold. And that reminder will come quickly. After one cold front passes early Tuesday with rain showers, we’ll get a treat with the milder air hanging around as it will be a second cold front that will deliver colder air for Wednesday, though nothing close to the magnitude of what we just saw.
Forecast details…
TODAY: Partly sunny. Highs 28-35. Wind SW 5-15 MPH, gusts 20-25 MPH.
TONIGHT: Variably cloudy. Lows 15-22. Wind SW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 35-42. Wind light variable.
SUNDAY NIGHT: Variably cloudy. Lows 25-32. Wind SW 5-15 MPH.
MONDAY: Partly cloudy. Highs 48-55. Wind SW 10-20 MPH.
TUESDAY: Variably cloudy with passing rain showers early, then partly cloudy. Breezy. Lows from the lower to middle 40s. Highs from the middle 50s to lower 60s.
WEDNESDAY: Partly sunny. Temperatures fall to the 30s.

DAYS 6-10 (FEBRUARY 7-11)
The large scale pattern will feature a flat ridge of high pressure in the southeastern US. With plenty of cold still residing in Canada, this sets up a contrast zone across the US Northeast and Mid Atlantic, which often become vulnerable to air mass battles. This doesn’t automatically mean big storms, big snow, or anything very specific. It does mean we tend to see a stretch of unsettled weather in the region, and this will likely be the case, first in the Northeast February 7-8 with odds favoring a low pressure track through the Great Lakes, mild air aloft, some low level cold, and a combination of rain/ice in the region – the details of which won’t be known for a few days. During the February 9-11 period the “zone of conflict” is more likely to shift into the Mid Atlantic leaving our area drier and seasonably chilly.

DAYS 11-15 (FEBRUARY 12-16)
It’s obviously been hard to confidently predict weather in this section of the blog for some time now, and this will be no different. However, the same basic weather pattern should be in place and the early feeling is that we get back into unsettled weather early in the period before shifting back to dry and colder mid to late period.

6:55AM

DAYS 1-5 (FEBRUARY 1-5)
We’ve gotten through the cold outbreak, which was a brief glancing blow by the edge of a piece of the Polar Vortex, which hit the Midwest much harder with extreme cold. While today will still be cold, it will be easier to take than yesterday with several degrees added to yesterday’s readings and somewhat less wind. A milder westerly air flow comes in Saturday but there will be some cloudiness to go along with it. High pressure will be in general control but a surface boundary will also be around late in the weekend pushing more to the north early in the week. A cold front comes through at some point during Tuesday, but it looks like this system may be moisture started, and we’ll have a better chance of rain showers from a trough that comes before it earlier in the day. It’s obviously several days away so the details may change.
Forecast details…
TODAY: Sunny. Highs 20-27. Wind W 5-15 MPH, higher gusts.
TONIGHT: Clear. Lows 8-15. Wind SW up to 10 MPH.
SATURDAY: Increasing clouds. Highs 28-35. Wind W 10-20 MPH.
SATURDAY NIGHT: Mostly cloudy. Lows 21-28. Wind NW 5-15 MPH.
SUNDAY: Partly cloudy. Highs 32-39. Wind N 5-15 MPH.
MONDAY: Mostly cloudy. Temperatures rise from the 30s to the 40s.
TUESDAY: Mostly cloudy with rain showers AM. Partly sunny PM. Breezy. Temperatures rise from the 40s to the 50s morning then fall back to the 40s afternoon.

DAYS 6-10 (FEBRUARY 6-10)
Slightly colder air arrives February 6 with dry weather. Next storm threat is February 7-8. Odds favor rain but some ice/snow is possible if the storm track is far enough south. Dry, colder weather expected during the weekend of February 9-10.

DAYS 11-15 (FEBRUARY 11-15)
Pattern should support a Great Lakes storm track about mid period with rain favored over freezing or frozen precipitation. This should be book-ended by dry weather to start and end to this period.

7:31AM

DAYS 1-5 (JANUARY 31-FEBRUARY 4)
We made it through the squalls, now to the arctic air, which blew in hard and harsh with the squalls last evening. Today won’t be quite as brutal as January 21, but almost as much adding the wind into the equation. But as previously discussed this doesn’t last long and even though we only recover to the 20s tomorrow, that will be part of a moderating trend that will last right through the 5-day period as high pressure sinks to the south of New England and a couple waves of low pressure move along a boundary to the north of the region.
Forecast details…
TODAY: Sunny. Highs 10-17. Wind W 15-25 MPH, higher gusts. Wind chill below 0 at times.
TONIGHT: Clear. Lows 0-7. Wind W 10-20 MPH, higher gusts. Wind chill near to below -10 at times.
FRIDAY: Sunny. Highs 20-27. Wind W 5-15 MPH, higher gusts. Wind chill near 10 at times.
FRIDAY NIGHT: Clear. Lows 8-15. Wind SW 5-15 MPH.
SATURDAY: Partly sunny. Highs 30-37. Wind SW 5-15 MPH.
SUNDAY: Partly cloudy. Lows in the 20s. Highs from the upper 30s to lower 40s.
MONDAY: Partly sunny. Lows in the 30s. Highs from the middle to upper 40s.

DAYS 6-10 (FEBRUARY 5-9)
Small disturbance brings a threat of early rain showers February 5 then drier and quite mild with high temps above 50 possible many areas. Next storm travels through the Great Lakes & St. Lawrence Valley February 6 bringing a risk of rain here but not looking too heavy. Drier, slightly colder after that but may need to watch for another low pressure wave with a variety of precipitation on February 8.

DAYS 11-15 (FEBRUARY 10-14)
Uncertainty here but leaning toward a chilly/dry start to the period, milder and unsettled mid period, colder and drier finish.

3:18AM

DAYS 1-5 (JANUARY 30-FEBRUARY 3)
The front and low pressure area that produced snow and rain overnight is on its way out now and today we await the arrival and passage of an arctic cold front, still expected to deliver snow showers and snow squalls to the region from west to east mid afternoon to early evening. These can drop visibility very quickly to near zero and also deposit a small accumulation of snow in short order, making for hazardous travel, so if you plan to be on the road later today, be aware of this possibility. This front will lead a shot of bitterly cold air into the region, along with wind, making the feel of this air mass rival that of January 21, even though the actual air temperatures will probably not be quite as cold as they were then. But I’m splitting hairs here – it will be very cold. Thankfully, we’re not actually getting into the full core of this cold air mass, as the heart of the air mass will peal northeastward and stay just north of our area as it heads back up into eastern Canada. So after this somewhat eventful end to the fairly uneventful month of January, what do the first few days of February have in store? The answer: Not much. It will be a quiet period of weather with temperature moderation taking place as high pressure moves overhead on Friday and then sinks to the south of the region during the course of the weekend. Although I cannot say with confidence the sky will be 100% clear on the morning of groundhog day, odds favor any small or large rodents that wander around outside will have a decent shot at seeing their shadows on Saturday morning, unless they rise before dawn! So there’s my groundhog day prediction! I will not venture to predict the score of the super bowl at this time – after all, it’s 5 days away and too early for numbers. 😉
Forecast details…
TODAY: Mostly cloudy early morning with snow/mix southeastern NH and northeastern MA and rain MA South Shore to Cape Cod diminishing. Sun/cloud mix mid morning on. Snow showers/squalls arriving from the west in central MA and southwestern NH by later in the afternoon. Highs 28-35. Wind W increasing to 15-25 MPH with higher gusts.
TONIGHT: Variably cloudy evening with snow showers/squalls likely. Briefly very low visibility in falling and blowing snow with accumulations of a coating to 1 1/2 inch possible. Clear overnight. Lows 3-10. Wind W 15-30 MPH with gusts 35-45 MPH. Wind chill falling well below 0 at times.
THURSDAY: Sunny. Highs 8-15. Wind W 15-25 MPH, higher gusts. Wind chill often below 0.
THURSDAY NIGHT: Clear. Lows 0-7. Wind W 5-15 MPH, higher gusts. Wind chill often below 0.
FRIDAY: Sunny. Highs 18-25. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Lows in the 0s. Highs from the middle 20s to lower 30s.
SUNDAY: Partly sunny. Lows from the middle 10s to lower 20s. Highs from the middle 30s to lower 40s.

DAYS 6-10 (FEBRUARY 4-8)
Monday February 4 will be a milder day overall with a warm front producing scattered rain/ice then a cold front later with rain showers. Fair, breezy, but on the mild side Tuesday February 5. Current expecting timing brings a risk of rain/mix February 6 and 8 although neither look like big storms as the overall pattern will be fairly zonal with split jet streams.

DAYS 11-15 (FEBRUARY 9-13)
Fairly zonal pattern with disturbances producing possible unsettled weather about February 10 and again toward the end of the period. Temperatures near to above normal.

7:23AM

DAYS 1-5 (JANUARY 29-FEBRUARY 2)
Light onshore flow produces some light ocean effect snow showers in eastern MA and southeastern NH through midday today with no significant impact. Low pressure tracking north of the region tonight into Wednesday will drag a front across the region, and its precipitation will arrive as mainly snow then change to mainly rain (except far north and west where it stays snow or briefly mixes) then may end as snow on the back side briefly Wednesday morning as a wave of low pressure forms on the front and cuts across the region from southwest to northeast. An arctic cold front charges across the region west to east during Wednesday afternoon and early evening, producing snow showers and squalls that may briefly bring visibility to very low levels and may coat the ground quickly with snow, creating hazardous travel. Once these are by, the door is open to bitterly cold air which will be here but for a brief visit late Wednesday night through early Friday, rivaling the magnitude of the cold of January 21, but probably falling just shy, but with wind, you won’t notice much of a difference anyway. Even though Friday’s still cold, it will be one of those days when the 20s feel like the 40s in comparison to the day before. Expect dry weather and further temperature moderation for Groundhog Day with high pressure in control.
Detailed forecast…
TODAY: Cloudy. Light snow showers with dustings and minor coatings eastern MA and southeastern NH through midday. Snow arriving in central MA, southwestern NH, and eastern CT to western RI by dusk. Highs 30-37. Wind NE to E up to 10 MPH this morning, E to SE up to 15 MPH this afternoon.
TONIGHT: Cloudy. Snow to possible mix northwest, snow to rain most other areas, and may just start as rain South Shore of MA and South Coast of MA/RI, then a brief switch back to snow in most areas pre-dawn before ending. Snow accumulation patchy coatings far southeastern areas, coating to 1 inch I-95 belt, 1-3 inches central MA and interior southern NH. Temperatures rise slightly to 32-36 north and west, 37-41 south and east through late evening then fall back to 25-32 around dawn. Wind variable 5-15 MPH, mainly NE to N interior areas and SE to S in coastal areas, shifting to N-NW all areas up to 10-20 MPH with higher gusts toward dawn.
WEDNESDAY: Mostly cloudy with a lingering snow shower eastern areas early then a sun/cloud mix. Snow showers/squalls likely west to east mid to late afternoon. Highs 28-35. Wind NW to W 10-20 MPH with higher gusts.
WEDNESDAY NIGHT: Partly cloudy with a few snow squalls around early then clear. Lows 0-7. Wind NW 15-30 MPH. Wind chill falling below 0.
THURSDAY: Mostly sunny. Highs 8-15. Wind NW 15-30 MPH. Wind chill well below 0 at times.
FRIDAY: Mostly sunny. Lows in the 0s. Highs in the 20s.
SATURDAY: Mostly sunny. Lows from the middle 0s to lower 10s. Highs from the upper 20s to middle 30s.

DAYS 6-10 (FEBRUARY 3-7)
Moderating temperatures with dry weather February 3 and a risk of rain showers later February 4. Dry and slightly cooler February 5. Unsettled weather possible with a risk of rain/mix/snow February 6-7 as we’ll be near a boundary between cold air north and mild air south.

DAYS 11-15 (FEBRUARY 8-12)
Unsettled weather departs early period and may return at the end of the period with variable temperatures. Not a great feel for how this period plays out at this time.

7:34AM

DAYS 1-5 (JANUARY 28-FEBRUARY 1)
High pressure brings seasonably cold weather to the region today. If you’re up early enough you may see a deck of clouds hiding the rising sun. These clouds are with an ocean storm that is missing the region. A couple hundred miles further west with that system and we’d be digging out from quite the snowstorm later today. But, not the case. The next winter weather event arrives later Tuesday as low pressure moves into the Great Lakes and a new low forms on its trailing front in the Middle Atlantic. This low will likely track right across southeastern New England Tuesday night, and this track will produce a snow-to-rain-to-snow scenario for many areas, but it may stay as snow/mix in the higher elevations of north central MA and southwestern NH throughout the event, where even though it won’t be a prolific producer, snow amounts there will be the highest. Before the arrival of this system, some eastern coastal areas of MA may see some ocean effect snow showers due to an onshore flow developing during the day Tuesday. As for the precipitation produced by the low, all areas end as snow at least briefly around dawn Wednesday as colder air rushes back in behind the departing low, and perhaps just enough to create some slippery travel for the morning commute in areas that didn’t really see any accumulation previously – something to watch for that morning. An arctic cold front will cross the region later Wednesday, bringing one of the better snow shower and snow squall chances we’ve had in a while. But squalls or not, the door will be open for a bitter blast of air, not quite to the degree of the one of January 21, but with more wind, making it feel just as cold if not a little colder when you factor that in. This will be for Thursday, the final day of the month. Triple-F Day, otherwise known as “Friday February First”, will open the new month on a cold note, but not as cold as the day before, as the core of the cold will have moved up in to the Canadian Maritimes by then. Earlier I had been thinking that we could see a sneaky snow event on that day, but at this time my feeling is that will be suppressed well to the south and pass through the Mid Atlantic region as a relatively minor system as high pressure builds in across New England.
Detailed forecast…
TODAY: High cloudiness hides the early morning sun then becoming mostly sunny. Highs 26-33. Wind N 5-15 MPH.
TONIGHT: Clouding up. Lows 15-22. Wind N
TUESDAY: Mostly cloudy. A few snow showers eastern MA coastal areas. Highs 30-37. Wind light NE to E.
TUESDAY NIGHT: Cloudy. Snow to possible mix northwest, snow to rain most other areas, and may just start as rain South Shore of MA and South Coast of MA/RI, then a brief switch back to snow in most areas pre-dawn before ending. Snow accumulation patchy coatings far southeastern areas, coating to 1 inch I-95 belt, 1-3 inches central MA and interior southern NH. Temperatures rise slightly to 32-36 north and west, 37-41 south and east through late evening then fall back to 25-32 around dawn. Wind variable 5-15 MPH, mainly NE to N interior areas and SE to S in coastal areas, shifting to N-NW all areas up to 10-20 MPH with higher gusts toward dawn.
WEDNESDAY: Mostly cloudy with a lingering snow shower eastern areas early then a sun/cloud mix. Late-day snow showers/squalls possible. Highs 28-35. Wind NW to W 10-20 MPH with higher gusts.
THURSDAY: Mostly sunny. Windy. Lows in the 0s. Highs in the 10s. Wind chill well below 0 at times.
FRIDAY: Mostly sunny. Lows in the 0s. Highs in the 20s.

DAYS 6-10 (FEBRUARY 2-6)
February 2-3 weekend looks dry, starting chilly ending milder as high pressure first over the region then sinks to the south and east. February 4 looks mild with possible rain showers. Windy, cooler, drier weather arrives February 5 as a cold front moves through and offshore. Will watch for a minor low pressure system with a threat of snow/mix by the end of the period.

DAYS 11-15 (FEBRUARY 7-11)
Seasonably chilly early period, milder following this with the next storm threat likely to be a Great Lakes system with mix/rain threat here, then a chilly end to the period. Confidence on timing low.

7:30AM

DAYS 1-5 (JANUARY 27-31)
The final 5 days of January will resent a variety of weather from mild to rain and snow to frigid cold, but will manage to avoid producing a major storm. However that does not mean we will be storm-free. After today’s nearly silent warm front / cold front combo goes through with little fanfare, and an ocean storm misses the area to the southeast later Monday, a front from the west will move in during Tuesday and a new low will form on it Tuesday night, pulling through the region and exiting Wednesday. This system will be responsible for the precipitation variety pack, probably starting as snow, going to rain, and ending as snow. Still have to fine-tune this one early in the week. What will follow it is a bitter blast of arctic air as a lobe of the Polar Vortex swings across the Northeast, although it appears the brunt of this will remain west and north of the region as the lobe starts to pull back into eastern Canada during its passage.
Detailed forecast…
TODAY: Variably cloudy. Slight risk of a rain or snow shower. Highs 38-45. Wind light variable early, becoming S 5-15 MPH, higher gusts.
TONIGHT: Variably cloudy. Lows 22-29. Wind shifting to W 5-15 MPH but a few higher gusts.
MONDAY: Partly cloudy. Highs 29-36. Wind N 5-15 MPH.
MONDAY NIGHT: Clouding up. Lows 15-22. Wind N 5-15 MPH.
TUESDAY: Mostly cloudy. Late-day snow/mix likely, changing to rain at night. Highs 32-39. Wind light variable becoming SE 5-15 MPH.
WEDNESDAY: Cloudy with rain/mix/snow potential to start, then sun/cloud mix with late-day snow shower possible. Temperatures start out upper 30s to lower 40s then fall rapidly by late-day.
THURSDAY: Mostly sunny. Lows in the 0s. Highs in the 10s.

DAYS 6-10 (FEBRUARY 1-5)
Risk of snow or snow showers February 1 from a passing disturbance then dry and cold February 2-3 weekend. Milder weather follows.

DAYS 11-15 (FEBRUARY 6-10)
Leaning a little more toward a milder scenario based on the latest info, but still have to watch plenty of cold air not all that far to the north. May turn a little more unsettle if we are close to the boundary.

8:32AM

DAYS 1-5 (JANUARY 26-30)
As we move into the late days of January we eye a couple more storm systems, neither of which look like impressive precipitation producers, although one will be more productive than the other, and we also look to the arrival of an arctic air mass at the very end of this 5-day period. First, we start with a fair but chilly day today as a narrow area of high pressure dominates. This high will move off to the east Sunday, which will end up a milder way as a warm front moves through while its parent low moves down the St. Lawrence Valley. This front may produce a touch of light snow, favoring areas north and west of Boston, and then a few rain showers may occur in the warm sector which will be over the region during the afternoon. This system’s cold front will come through uneventfully late in the day and will return colder air to the region for Monday as an extension of high pressure in east central Canada noses into New England. While this is happening, a strong ocean storm will get going and travel up along the cold front as it continues to move away from New England later Monday, so that storm will safely remain over the water. During this time, another low will travel into the Great Lakes, bringing our next round of unsettled weather into the region Tuesday. This looks like another warm front / cold front combo, and with a little more moisture to work with more of the region should see a snow to mix to rain situation. The initial cold front coming through early Wednesday will be in the process of having a wave of low pressure develop on it, and this may occur right over southern New England so that there may be a burst of rain ending as mix or snow as colder air arrives. Will have to keep an eye on this as enough snow at the wrong time could cause issues with the Wednesday morning commute, but being several days away still it’s really impossible to know how this will work out, specifically. During the day Wednesday, a secondary cold front will come through, possibly with a snow shower, and definitely introducing some of the coldest air of the season-so-far with a temperature free-fall likely occurring by the end of the day. Will work on the timing and details.
Detailed forecast…
TODAY: Partly sunny. Highs 26-33. Wind W to SW up to 10 MPH.
TONIGHT: Variably cloudy. Lows 15-22. Wind light variable.
SUNDAY: Mostly cloudy morning with a couple periods of light snow possible, favoring northern MA and southern NH. Variably cloudy afternoon with a passing rain shower possible. Highs 38-45. Wind light variable early, becoming S 5-15 MPH.
SUNDAY NIGHT: Variably cloudy. Lows 22-29. Wind shifting to W 5-15 MPH but a few higher gusts.
MONDAY: Partly cloudy. Highs 29-36. Wind N 5-15 MPH.
TUESDAY: Cloudy. Snow/mix/rain. Temperatures rise through the 30s.
WEDNESDAY: Cloudy with rain/mix/snow potential to start, then sun/cloud mix with late-day snow shower possible. Temperatures start out upper 30s to lower 40s then fall rapidly by late-day.

DAYS 6-10 (JANUARY 31-FEBRUARY 4)
Dry and very cold end to January. Will watch a low pressure trough coming along which may spawn a surface low and a chance of snow February 1 before drier and a more modified cold for the February 2-3 weekend. A warm-up possible to end the period.

DAYS 11-15 (FEBRUARY 5-9)
The weather is somewhat more indeterminate than is even average for a period 11 to 15 days away. Trying not to be swayed by inconsistent guidance and have seen signals for both moderation and a cold/dry pattern. Will split the difference for now and call for a few air mass changes but minor weather systems between them.

7:09AM

DAYS 1-5 (JANUARY 25-29)
Dry air has replaced the mild/wet/windy weather of yesterday. A secondary cold front may produce a snow shower this evening and will lead colder air into the region for the start of the weekend. Later in the weekend a passing disturbance may bring showers of snow and rain. With a trough in place in the Northeast another low pressure system will bring the chance of snow/mix/rain by Monday night into Tuesday. Detailed forecast…
TODAY: Variably cloudy. Isolated to scattered snow showers mid afternoon on. Highs 33-40. Wind W 5-15 MPH, higher gusts possible.
TONIGHT: Partly cloudy. Isolated snow showers evening. Lows 13-20. Wind NW 10-20 MPH and gusty early, diminishing overnight.
SATURDAY: Partly sunny. Highs 26-33. Wind W to SW up to 10 MPH.
SATURDAY NIGHT: Variably cloudy. Lows 15-22. Wind light variable.
SUNDAY: Variably cloudy. Passing snow and rain showers possible. Highs 35-42. Wind S 5-15 MPH.
MONDAY: Mostly sunny day. Clouds arrive with a risk of snow late night. Lows in the 20s. Highs in the 30s.
TUESDAY: Mostly cloudy. Risk of rain/mix/snow. Temperatures generally in the 30s.

DAYS 6-10 (JANUARY 30-FEBRUARY 3)
A period of below to much below normal temperatures as a lobe of the polar vortex brings arctic air into the region during this period. No major storminess expected, just some light snow or snow showers events possible.

DAYS 11-15 (FEBRUARY 4-8)
My leaning is toward colder and drier than normal at this time with polar jet stream dominant and mean polar vortex lobe position in eastern Canada.

7:35AM

DAYS 1-5 (JANUARY 24-28)
Now comes that spring preview, ok maybe I’m getting a little ahead of myself on that one, but the thought of many that venture outside today, even during the rain, is how much it feels like a spring day. And it should, today’s high temperatures would be above average for some of our early spring days here in New England, but I would also be lying if I told you this was highly unusual for a winter’s day. This is just the variety that our weather prevents, like going from the single-digit arctic deep-freeze of just 3 days ago to this. There will be pros and cons to today’s weather, with the most obvious pro being the natural melting of much of the packed ice/snow that lies on our paths of mobility. Much of this, and all of it in many cases, will be vanished by day’s end. The cons are several, but the most obvious will be the areas of flooding that ensue due to heavier rainfall on frozen ground as well as not being unable to run off due to some still-clogged storm drains. But we will get through this, and after it all pushes offshore tonight, the temperatures will fall back toward seasonable levels, but this time we won’t see the flash freeze and tundra-like landscape. However we will have to be concerned with black ice and re-freezing of puddles and any standing water, because despite an increasing wind it won’t be enough to fully dry everything off. This will also be a concern for the couple days following today as it will be getting cold again so any ice will tend to linger. Along with this colder air, which gets reinforced this weekend, may come some snow showers, first of the isolated variety Friday evening as cold front goes by, and secondly from a disturbance crossing the region on Sunday. We’ll have our eyes on a third system approaching from the west Monday but before that gets here, our wind may turn onshore due to high pressure to the north and that may bring in enough moisture for some ocean-effect snow showers. But this is still a few days away so I’m not highly confident this will take place.
TODAY: Overcast. Numerous to widespread rain showers. Downpours and possible thunder west to east mid through late afternoon. Areas of fog.
Highs 48-55. Wind S 10-20 MPH with gusts 35-55 MPH, strongest coastal areas, shifting to W during the day from west to east.
TONIGHT: Cloudy evening with rain ending, maybe as brief mix some areas west of Boston. Clearing overnight. Areas of black ice possible. Lows 25-32. Wind NW 10-20 MPH and gusty.
FRIDAY: Mostly sunny to partly cloudy. Highs 32-39. Wind NW to W 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Risk of a passing snow shower. Lows 13-20. Wind W to NW 10-20 MPH with higher gusts.
SATURDAY: Partly sunny. Highs 23-30. Wind W 5-15 MPH.
SUNDAY: Variably cloudy. Chance of snow showers except mix/rain showers South Coast. Lows in the 10s. Highs in the 30s.
MONDAY: Mostly cloudy. Possible snow showers. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (JANUARY 29-FEBRUARY 2)
Potential storm system moving through January 29 with the early leaning toward a light to moderate precipitation variety due to a storm track over or northwest of the region. Colder trend thereafter at which time we’ll have to watch additional storminess which is favored to pass mostly south of the region at this time.

DAYS 11-15 (FEBRUARY 3-7)
A broad trough will dominate and a surface low may cut through the Great Lakes around mid period. Our weather here would be dry/cold to start, briefly mild/wet, then dry/cold to finish the period. Forecast not high confidence.

7:31AM

DAYS 1-5 (JANUARY 23-27)
High pressure offshore and a slow-moving cold front approaching from the west today brings milder but mainly cloudy weather today. Wet weather arrives west to east during this evening as the front draws near, and a wave of low pressure forming on it and moving up along it will enhance the wet weather through most of Thursday. We’ll have to watch for a concentrated line of downpours and gusty winds associated with this system as it has been strongly indicated by short-range guidance. Rough idea on timing of this feature, if it occurs, would be late morning to mid afternoon from west to east across the region. By Thursday evening, the wet weather will come to an end as the cold front starts to push offshore after the low pressure wave goes by. This will bring drier and seasonably colder weather in for Friday. During this warm-up, we should be able to get rid of a fair amount of our tundra-like snow/ice left on the ground by the Sunday storm and frozen in place by the arctic air that followed it. Speaking of arctic air, we’ll get a taste of that, but to a lesser degree, by Saturday. And then by Sunday a disturbance should throw some snow showers into the mix. This doesn’t look like an important storm at this point.
Forecast details…
TODAY: Mostly cloudy. Rain showers arriving western areas later in the day, with patchy freezing rain possible interior areas to start. Highs 38-45. Wind S to SW 5-15 MPH with higher gusts.
TONIGHT: Cloudy with rain showers likely evening becoming a steady rain overnight. Areas of fog. Temperatures steady 38-45. Wind SW 10-20 MPH, higher gusts possible especially South Coast.
THURSDAY: Overcast. Rain likely. One or two period of heavy rain possible. Areas of fog. Highs 48-55. Wind S 10-20 MPH with gusts 35-55 MPH, strongest coastal areas, shifting to W during the day from west to east.
THURSDAY NIGHT: Cloudy evening with rain ending, maybe as brief mix some areas west of Boston. Clearing overnight. Areas of black ice possible. Lows 25-32. Wind NW 10-20 MPH and gusty.
FRIDAY: Mostly sunny to partly cloudy. Risk of a snow shower evening. Breezy. Highs 32-39. Wind NW to W 10-20 MPH.
SATURDAY: Partly sunny. Windy. Lows in the 10s. Highs in the 20s.
SUNDAY: Mostly cloudy. Chance of snow showers. Lows in the 10s. Highs from the middle 20s to lower 30s.

DAYS 6-10 (JANUARY 28-FEBRUARY 1)
A potential storm during the January 28-29 period but not sure if all the ingredients will come together for a significant event as it is too far away to be sure. Leaning toward dry/cold for the end of January / beginning of February but may have to watch additional storminess to the south and east.

DAYS 11-15 (FEBRUARY 2-6)
Somewhat active pattern so may have to watch 1 or 2 weather systems in this time period and with the temperatures still trying to average below normal that would leave the door open for snow chances (don’t interpret this as “here come the blizzards!” because it’s not really what I mean). Been monitoring for a potential pattern retrogression and moderation, but it appears that would attempt to take place after this time period.

7:35AM

DAYS 1-5 (JANUARY 22-26)
Arctic high pressure moves overhead today, which will still be cold and breezy, but not nearly as cold as yesterday was. High pressure then move offshore and opens the door for a midweek warm-up, but the trade-off will be wet weather arriving by late Wednesday through Thursday. Colder/drier air returns by Friday, but only seasonable cold as the slow-moving front that creates the midweek wet spell moves offshore. But a second cold front will deliver colder air by the start of the weekend.
Forecast details…
TODAY: Sunshine, filtered late by high clouds. Highs 21-28. Wind NW 5-15 MPH, gusts 20-25 MPH. Wind chill often below 20.
TONIGHT: Clouding over. Lows 11-18 evening, rising back to the 20s overnight. Wind light variable early, becoming light S to SW.
WEDNESDAY: Cloudy. Rain showers arriving west to east during the afternoon, with patchy freezing rain possible interior areas to start. Areas of fog mid to late afternoon. Highs 38-45. Wind S to SW 5-15 MPH with higher gusts.
WEDNESDAY NIGHT: Cloudy with rain showers likely evening becoming a steady rain overnight. Areas of fog. Temperatures steady 38-45. Wind SW 10-20 MPH, higher gusts possible especially South Coast.
THURSDAY: Overcast. Rain likely. Areas of fog. Highs 45-52. Wind S 10-20 MPH with higher gusts, shifting to W during the day from west to east.
FRIDAY: Mostly sunny to partly cloudy. Risk of a snow shower evening. Breezy. Lows in the 20s. Highs in the 30s.
SATURDAY: Partly sunny. Chance of snow showers. Windy. Lows in the 10s. Highs in the 20s.

DAYS 6-10 (JANUARY 27-31)
Will watch the January 27-29 period for potential storminess which would occur while it was cold enough for snow/mix. Dry, cold end to month.

DAYS 11-15 (FEBRUARY 1-5)
Starts out cold/dry, some unsettled weather follows as it tries to moderate. This forecast is purposely vague and low confidence because of the uncertainty of the large scale pattern. May see retrogression of trough toward the western US but unsure how quickly this might take place.

7:23AM

DAYS 1-5 (JANUARY 21-25)
I bet many of you are tired from dealing with winter weather and perhaps watching an exciting football game, or perhaps some of you, like me are battling with or recovering from a winter cold, so today’s blog update will be short and to-the-point. Kind of taking it easy. First, it’s a bitterly cold northwesterly air flow today with arctic air dominating, and other than a few ocean-effect flurries on the outer part of Cape Cod we’ll see dry weather, then we moderate ever so slightly as high pressure moves overhead Tuesday. This high moves offshore by Wednesday and a cold front approaches, and it warms significantly that the next round of precipitation falls as rain showers, however it may be cold enough at ground level for some freezing rain at the start from this, so something to keep an eye on. This front will get hung up in its attempt to get offshore Thursday and with low pressure riding up along it, it means more precipitation, but this time it will be mild enough for a rain event. However as it pulls away, there may be just enough cold air to end it as a mix or brief snow at night, if the timing is correct. On Friday we’re back to chilly and dry weather for the most part, but a disturbance approaching later in the day and evening may trigger some snow showers.
Forecast details…
TODAY (MLK JR DAY): Partly sunny. A few snow flurries outer Cape Cod. Highs 5-12. Wind NW 15-25 MPH, higher gusts. Wind chill -5 to -15 at times.
TONIGHT: Clearing. Lows -2 to +5. Wind NW 5-15 MPH, higher gusts. Wind chill -8 to -15 at times.
TUESDAY: Mostly sunny. Highs 22-29. Wind NW 5-15 MPH becoming light variable during the afternoon.
TUESDAY NIGHT: Partly cloudy. Lows 11-18 evening, then slowly rising overnight. Wind light variable evening, light S overnight.
WEDNESDAY: Partly sunny early, then mostly cloudy. Rain showers arriving west to east but may fall as freezing rain at first. Highs 38-45. Wind S to SW increasing to 10-20 MPH.
THURSDAY: Cloudy. Rain, may end as mix/snow late. Temperatures fall from the 40s to the 30s.
FRIDAY: Partly cloudy. Risk of snow showers late-day and evening. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (JANUARY 26-30)
Colder air will dominate much of this period. We’ll have to watch the January 27-29 period for potential storminess, but the very early idea is that it may be too far south and east to have a significant impact and we’d just see more energy from the polar jet stream with snow showers. Low confidence. Many days to iron it out. Fair weather later in the period.

DAYS 11-15 (JANUARY 31 – FEBRUARY 4)
Large scale pattern retrogression (westward movement) may occur with low pressure scooting back to the west and a flat ridge in the US Southeast. This would allow some milder weather and a westerly flow with minor weather systems passing through the region. Again a low confidence forecast for this period.

8:55AM

DAYS 1-5 (JANUARY 18-21)
We saw the snow behave about as expected, and based on the later-day update, the changeover lines as well. The little details are still revealing themselves as the storm is progressing, and one thing to watch has been a boundary between milder and very cold air that slid down the Maine and NH Coasts into northeastern MA overnight, putting places like Lawrence into the middle and upper teens while Boston was reaching the middle 30s. This boundary, as of the writing of this blog, is slowly coming down the coast of MA now and we will have to see if it reaches the city of Boston before the morning is over. While we have a variety of precipitation from sleet and freezing rain over many areas to just plain rain where it’s mild enough, all of this will continue for some time, with areas seeing freezing rain the longest obviously having the most direct impact. But later, as precipitation begins to taper off, possibly as snow in some areas, the big story will become the temperature drop in areas that were in the milder air. Anything wet or any slush/snow not removed will freeze solid in very rapid fashion by the end of the day today. That will be the largest threat leftover with this event, other than the ongoing freezing rain. Still looking for a clearing trend tonight, but the definite is the bitter cold and strong wind, so if you do plan to try viewing the total lunar eclipse, you may want to choose a window to look out of rather than going outside. I think there will be enough clear sky to see it. Not forgetting coastal flooding, which will be an issue from mid morning to midday around the late morning high tide, which is astronomically quite high anyway and being added to by some moderately strong wind along the coast. Fairly widespread minor flooding is expected with pockets of moderate flooding. By tonight, a north northwest wind will mean minor flooding should be confined to north-facing shores of Cape Cod Bay with the late evening high tide. It will be cold enough by then that any splash over is likely to freeze on anything it makes contact with. So once this is over, we won’t have anything to talk about right? I mean everybody else may be talking about blizzards on models that won’t verify, but here at WHW we’ll talk about the upcoming few days, and you might wanna listen, because Monday is going to be one cold day, with lots of wind. Straight shot of Arctic air and wind chill to emphasize it. But at least it will be dry! There may be no more ice falling from the sky, but there will be plenty of ice left on the ground, so be careful if you will be out there. As we approach midweek, the cold eases a bit Tuesday, and much more so Wednesday and Thursday, which will turn somewhat unsettled as a front arrives and then hangs around. The details of this still have to be figured out, so the forecast below will be fairly generic to reflect the unknowns a few days out.
Forecast details…
TODAY: Overcast with sleet, freezing rain, rain to the southeast, some snow southwestern NH, then all precipitation tapering off west to east late in the day. Thunder is possible RI and southeastern MA mid to late morning. Large temperature contrast ranging from around 15 northern MA and southern to NH to the 40s South Coast, but temperatures falling below 10 north and all the way to the 10s south by the end of the day. Wind variable 15-25 MPH South Coast, becoming N with higher gusts late-day, and elsewhere wind E to N 5-15 MPH increasing to 15-25 MPH late day. Higher wind gusts all areas late in the day. Wind chill falling below 0 by end of day.
TONIGHT: Partly cloudy. Lows 0-7. Wind N to NW 15-30 MPH. Wind chill frequently -5 to -10 and occasional -10 to -20.
MONDAY (MLK JR DAY): Sun and passing clouds. Highs 8-15. Wind NW 15-30 MPH. Wind chill frequently -5 to -15.
MONDAY NIGHT: Clear. Lows 0-7. Wind NW 15-25 MPH, diminishing gradually. Wind chill below -10 at times.
TUESDAY: Sunny. Highs 21-28. Wind NW 5-15 MPH, a few higher gusts.
WEDNESDAY: Mostly cloudy. Chance of snow/mix showers transitioning to rain showers. Temperatures rise from the 20s to the 40s.
THURSDAY: Cloudy. Chance of rain, may end as mix/snow late. Temperatures fall from the 40s to the 30s.

DAYS 6-10 (JANUARY 25-29)
Seasonably chilly January 25, dry during day but snow showers at night as much colder air arrives for the January 26-27 weekend with a couple periods of snow showers possible. Slight moderation, still cold, and mostly dry end of period.

DAYS 11-15 (JANUARY 30-FEBRUARY 3)
Look for a colder than average period of weather, dominated by a polar jet stream and minor systems with snow shower threats.
