DAYS 1-5 (JANUARY 2-6)

You’ve made it to the second day of 2021! And the weather today is just as expected. Last night, precipitation arrived as snow in all areas west and north of Boston, a few flakes in the city, and generally rain to the southeast. The initial burst of snow was enough accumulate a coating to 2 inches, as expected. Here at the WHW location in Woburn Massachusetts I measured 7/10 of an inch (0.7) of snowfall before the band moved away and it ended. When precipitation returned, it was in the form of sleet then went to rain. During the overnight hours it became rain in all areas, but some of that rain was freezing on untreated surfaces north and west of Boston, especially in Worcester County where temperatures held close to or just below freezing longest while other areas warmed to the upper 30s and lower 40s pre-dawn. The hold-out areas will warm toward 40 today and any icing should melt away. The entire region is starting overcast with areas of rain and some fog today as low pressure tracks across southeastern New England, and as that low makes its way east and northeast of the region this afternoon and evening we’ll see the return of dry air and some clearing. As the temperature drops tonight, watch for the formation of black ice on untreated surfaces, into Sunday morning as well. Most of this will vanish due to dry air by later Sunday morning. Sunday will be a nice winter day, but don’t expect total sunshine as clouds will be rapidly moving back into the region in advance of the next low pressure system, which will bring its shield of precipitation into the region late Sunday and into Monday. The question with this system is its organization and battle against some dry air. It will have colder air to work with, so the snow potential extends a little further south and east than the system just before it, but at the same time it will be fighting dry air that may try to eat away at the precipitation. Some of the shorter range guidance has been insisting on an offshore intensification of this system, dragging cold air eastward and creating a snow situation with a bit more potential to it, while other guidance has had this occurring a little too far offshore to have much of an impact. No surprise that the guidance continues to struggle with these details but they should iron things out over the next few runs. In the mean time, I’ll just continue the idea from yesterday, and based on this, this is my early call on snowfall accumulation through Monday evening… No accumulation for outer Cape Cod and Nantucket, a slushy coating for Cape Ann MA, lower Cape Cod, and Martha’s Vineyard, northwestward to about Plymouth and westward along the South Coast, a coating to 1 inch from the South Shore north of Plymouth to southern RI away from the coast as well as northward to the immediate North Shore of the Boston area, 1-3 inches for the I-95 belt and the lower part of the I-495 belt south of I-90, and 3-5 inches for the I-495 belt from I-90 northward. This system will be hanging around underneath upper level low pressure offshore Tuesday and perhaps even into Wednesday (a little longer than previously expected) keeping it on the unsettled side here with the potential for rain and snow showers.

TODAY: Overcast with areas of fog & drizzle along with periods of rain this morning. Breaking clouds from west to east this afternoon. Highs 45-52. Wind E 5-15 MPH backing to N then W with higher gusts at times.

TONIGHT: Clearing. Lows 23-30. Watch for black ice formation. Wind W 5-15 MPH, diminishing.

SUNDAY: Increasing clouds. Snow, except mix/rain South Coast, arriving by the end of the day. Highs 35-42. Wind N up to 10 MPH.

SUNDAY NIGHT: Cloudy. Periods of snow except mix/rain in coastal areas. Lows 30-37. Wind NE 5-15 MPH.

MONDAY: Cloudy. Rain (mostly coast) & snow (mostly interior) may get heavier and rain may change to snow in all areas by later in the day. Highs 32-39. Wind NE to N 10-20 MPH, higher gusts.

MONDAY NIGHT: Cloudy. Snow/mix/rain tapering off to spotty and lighter. Lows 23-30. Wind N to NW 10-20 MPH, higher gusts.

TUESDAY THROUGH WEDNESDAY: Variably cloudy. Snow and/or rain showers possible. Temperatures generally 32-39. Wind N to NW 10-20 MPH, higher gusts.

DAYS 6-10 (JANUARY 7-11)

The delay in departure of the low pressure area into midweek likely delays the arrival of the next system or changes its track somewhat. Need to watch later January 8 through January 10, but this system could easily end up passing south of there region. Will keep a close eye on its evolution.

DAYS 11-15 (JANUARY 12-16)

Blocking pattern expected. Next storm threat window later January 12 through January 14.

C-19 Chat Post – January 2 2021

DAYS 1-5 (JANUARY 1-5)

Happy New Year to all! We start 2021 with an active weather pattern bringing 2 bouts of unsettled weather during its first 5 days. Today starts bright and cold with sun & high clouds as high pressure sits over the region. We’ll see cloudiness advance during the day as the high pressure area starts a northeastward retreat and low pressure approaches from the southwest. This low pressure area will be heading for the eastern Great Lakes, but along its warm front we’ll see a secondary low pressure area develop, near Long Island, then track northeastward across southeastern New England Saturday morning. This will be a progressive system with precipitation arriving as snow for most areas tonight, except rain along the South Coast, then transitioning to sleet & rain from south to north as warmer air comes in aloft, but surface cold will probably allow a period of freezing rain and some glazing of ice to take place across Worcester County, adjacent northeastern CT, and along the I-495 belt from near I-90 northward into southern NH, so be aware that any untreated surfaces may become very slippery. Temperatures should make it above freezing in all areas as the rain moves out from southwest to northeast by late morning or midday Saturday, and clouds will break as the secondary low exits via the Gulf of Maine, pulling drier air back in behind it. Similar to today, high pressure will then build in for Saturday night and early Sunday with dry/colder air. Watch for the formation of black ice Saturday night on surfaces that don’t dry off. Another low pressure area will make a run at us from the southwest later Sunday, and the slower movement of this one will allow it to hang around offshore Monday and even into Tuesday. This one should again begin as snow for most of the region except possibly mixed precipitation or rain for the South Coast, and drier air may eat away at the precipitation area for a time on Sunday night, but Monday’s situation may become more complex as the low center gets a shot of energy and intensifies, making for heavier precipitation at the same time colder air is drawn closer to the storm center. This would mean a better chance of accumulating snow for more of the region, including Boston. We’ll have to see how far south and east it can get from there, as temperatures will probably still be marginal or just too mild for all snow for at least a while. At this time, I do think while the low will be close enough to potentially bring snow and rain showers to at least eastern coastal areas, especially Cape Cod, on Tuesday, it should be far enough offshore to not bring any steady precipitation to the region.

TODAY: Sunny start, cloudy finish. Highs 32-39. Wind N up to 10 MPH.

TONIGHT: Cloudy. Snow, except rain South Coast, arriving southwest to northeast by late evening, may mix with sleet before changing to rain except freezing rain over northeastern CT, interior MA, and southern NH. Snow accumulation of a coating to 2 inches away from the coast, highest amounts in the higher elevation of southwestern NH and central MA. Lows 29-36 evening, rising slowly overnight. Wind N to NE up to 10 MPH inland and 10-20 MPH coast.

SATURDAY: Cloudy with areas of fog and a chance of rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind NE to variable 5-15 MPH becoming W.

SATURDAY NIGHT: Clearing. Lows 23-30. Watch for black ice formation. Wind W up to 10 MPH.

SUNDAY: Increasing clouds. Snow, except mix/rain South Coast, arriving by the end of the day. Highs 35-42. Wind N up to 10 MPH.

SUNDAY NIGHT: Cloudy. Periods of snow except mix/rain in coastal areas. Lows 30-37. Wind NE 5-15 MPH.

MONDAY: Cloudy. Rain (mostly coast) & snow (mostly interior) may get heavier and rain may change to snow in all areas by later in the day. Highs 32-39. Wind NE to N 10-20 MPH, higher gusts.

MONDAY NIGHT: Cloudy. Snow/mix/rain tapering off. Lows 23-30. Wind N to NW 10-20 MPH, higher gusts.

TUESDAY: Variably cloudy. Snow and/or rain showers possible. Highs 32-39. Wind N to NW 10-20 MPH, higher gusts.

DAYS 6-10 (JANUARY 6-10)

Transition to a blocking pattern. Seasonably cold & dry weather will flank one storm threat that comes around January 8.

DAYS 11-15 (JANUARY 11-15)

Indications are for stronger blocking. Storm threat in the January 12-14 window.

C-19 Chat Post – January 1 2021

DAYS 1-5 (DECEMBER 31 – JANUARY 4)

On this final day of 2020, we won’t see much sun, but after morning rainfall exits the South Coast region, it will be a dry day. High pressure building across eastern Canada and pushing down into New England will bring some clearing tonight and 2021’s first day will dawn with sunshine, but clouds will advance steadily as the day goes on and another low pressure area approaches from the southwest. This system will have colder air to work with so snow & sleet are likely to be at the leading edge of the precipitation shield of this low pressure area when it arrives on Friday evening, but warmer air aloft will change that to rain during the night and into Saturday morning. However some colder air trapped at the surface may result in some pocket of freezing rain mainly over interior valley locations before temperatures rise sufficiently to eliminate that issue. By Saturday afternoon, low pressure will have crossed the region and drier air will be moving in behind it. But this dry interlude will also be short-lived, as a follow-up low will pass by the region Sunday night into Monday with another period of precipitation, the details of which still need to be worked out.

TODAY: Mostly cloudy. Rain South Coast region this morning. Highs 42-49 this morning, then slowly falling temperatures during the afternoon hours. Wind W 5-15 MPH with higher gusts.

TONIGHT (NEW YEAR’S EVE): Clearing. Lows 18-25. Wind N 5-15 MPH evening, diminishing overnight.

FRIDAY: Sunshine fading behind increasing high cloudiness. Highs 32-39. Wind N up to 10 MPH.

FRIDAY NIGHT: Thickening overcast with snow/sleet northwestern areas and mix/rain southeastern areas arriving from southwest to northeast, changing to rain except possible freezing rain interior valley locations. Lows 30-37. Wind N to NE up to 10 MPH inland and 10-20 MPH coast.

SATURDAY: Cloudy with areas of fog and a chance of rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind NE to variable 5-15 MPH becoming W.

SATURDAY NIGHT: Clearing. Lows 25-32. Watch for black ice formation. Wind W up to 10 MPH.

SUNDAY: Increasing clouds. Chance of rain/mix/snow by late in the day. Highs 36-43. Wind N up to 10 MPH.

SUNDAY NIGHT & MONDAY: Cloudy with rain/mix/snow possible. Temperatures 35-45. Wind NE to variable 10-20 MPH shifting to N.

DAYS 6-10 (JANUARY 5-9)

High pressure builds in with fair weather January 5. Weak system may bring a few rain/snow showers, milder on January 6. High pressure builds back in with fair weather January 7. Next threat of unsettled weather comes from passing low pressure about January 8 before dry/cold weather ends the period.

DAYS 11-15 (JANUARY 10-14)

Stronger indications of a blocking pattern setting up during this period. Will have to watch one or two low pressure areas, strongest chance for unsettled weather around January 12-13.

C-19 Chat Post – December 31 2020

DAYS 1-5 (DECEMBER 30 – JANUARY 3)

After much of the region saw a very nice sunrise, an abundance of high & mid level cloudiness will limit sunshine today as a warm front moves across the region. The precipitation associated with this front, which is not too prominent anyway, will pass north of the WHW forecast area. This warm front is parented by low pressure which will be passing north of our area tonight and dragging its trailing cold front across the region Thursday morning, bringing with it a period of rainfall before drier air returns during the day from northwest to southeast with some partial clearing occurring. High pressure, initially under-forecast by guidance, will be quite strong as it builds across eastern Canada and exerts its influence on us here, bringing cold and dry weather for New Year’s Eve & New Year’s Day. If you recall, just a few days ago, most guidance had been calling for a repeat of the warm/set scenario of Christmas Day, but this is a vivid example of why we don’t just look at the models and make that the forecast. The storm system that this guidance was trying to track so quickly well northwest of our area is going to be a little slower-moving, and track much further southeast, passing right over the area early Saturday. Ahead of it, when its precipitation shield arrives during Friday night, it will likely be cold enough so that it begins as snow & sleet in some areas, especially away from the coast, but warmer air moving in aloft will change this precipitation to rain, although a period of icing is quite possible over interior locations, especially valleys, where surface cold air is always a lot harder to dislodge. Eventually, as low pressure moves east of us during Saturday, drier air will return, and we’ll see improvement in the majority of the region before the end of the day, but it now appears this improvement will be rather short-lived, into the first part of Sunday, before follow-up low pressure tracks south of the region, but close enough to bring its envelope of precipitation into at least the southeastern portion of the area by Sunday night. The timing and precipitation type details still need to be worked out, but odds favor a little bit more snowfall coverage with that one, provided it gets far enough north.

TODAY: Sunshine limited by high & mid level clouds. Highs 33-40. Wind W up to 10 MPH.

TONIGHT: Mostly cloudy. Rain, may begin as sleet, arriving in southern NH and northern MA pre-dawn. Lows 25-32 evening, rising through the 30s overnight. Wind S under 10 MPH.

THURSDAY: Cloudy morning with rain progressing southeastward through the region. Mostly cloudy to partly sunny afternoon. Highs 42-49. Wind SW 5-15 MPH shifting to NW.

THURSDAY NIGHT (NEW YEAR’S EVE): Partly cloudy. Lows 18-25. Wind N 5-15 MPH evening, diminishing overnight.

FRIDAY: Sunshine fading behind increasing high cloudiness. Highs 32-39. Wind N up to 10 MPH.

FRIDAY NIGHT: Thickening overcast with snow/sleet northwestern areas and mix/rain southeastern areas arriving from southwest to northeast, changing to rain except possible freezing rain interior valley locations. Lows 30-37. Wind N to NE up to 10 MPH inland and 10-20 MPH coast.

SATURDAY: Cloudy with areas of fog and a chance of rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind NE to variable 5-15 MPH becoming W.

SATURDAY NIGHT: Partly cloudy. Lows 25-32. Watch for black ice formation. Wind W up to 10 MPH.

SUNDAY: Partly sunny. Snow/mix/rain possible at night. Highs 35-42. Wind N up to 10 MPH.

DAYS 6-10 (JANUARY 4-8)

Low pressure passing southeast of the region may impact the area with snow/mix/rain January 4. High pressure builds in with fair weather January 5. Weak system may bring a few rain/snow showers, milder on January 6. High pressure builds back in with fair weather January 7. Next threat of unsettled weather comes from passing low pressure about January 8. Temperatures variable, not too far from normal.

DAYS 11-15 (JANUARY 9-13)

Stronger indications of a blocking pattern setting up during this period. Generally dry and seasonably cold weather to start out in our area, but a chance of some unsettled / wintry weather comes later in the period.

C-19 Chat Post – December 30 2020

DAYS 1-5 (DECEMBER 29 – JANUARY 2)

High pressure builds into the region today, which will be breezy, cold, & dry. High pressure crests over the region Wednesday with cold, tranquil weather, but you’ll notice an increase in high cloudiness ahead of a warm front, which will quietly move through the region during the evening hours as a lead low pressure area tracks north of the region. This low will drag a cold front through here Thursday morning with cloudiness and a rain shower risk, as a shot of milder air will have moved in behind the warm front and ahead of the cold front. The entire evolution of the New Year’s Eve & New Year’s Day set-up looks different on recent guidance than it did on previous guidance, which was showing a set-up very similar to that of last week (Christmas Eve / Christmas Day). But we know guidance has been struggling, but seems to have resolved at least to the idea of the weaker low passing north late Wednesday & early Thursday, high pressure building across eastern Canada to bring some colder air back in for New Year’s Eve, and then low pressure from the southwest making a run at our area later Friday into Saturday. The details of this particular low pressure area are still not worked out, but the general idea is that the onset of precipitation sometime Friday afternoon or evening may be in the form of snow/sleet & freezing rain for some areas, especially away from the coast, before rain takes over, possibly leaving some pockets of freezing rain a bit longer over interior valleys, before tapering off at some point Saturday, depending on details of frontal boundaries and low pressure track. More fine-tuning needed there which will take place as we get closer to this event.

TODAY: Sun & passing clouds. Highs 32-39. Wind NW 10-20 MPH.

TONIGHT: Clearing. Lows 13-20. Wind NW 5-15 MPH, diminishing.

WEDNESDAY: Sun & high clouds. Highs 33-40. Wind W up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 23-30. Wind S under 10 MPH.

THURSDAY: Mostly cloudy with a chance of rain showers in the morning. Partly sunny in the afternoon. Highs 43-50, occurring in the morning. Wind SW 5-15 MPH shifting to NW.

THURSDAY NIGHT (NEW YEAR’S EVE): Partly cloudy. Lows 25-32. Wind N 5-15 MPH evening, diminishing overnight.

FRIDAY (NEW YEAR’S DAY): Clouding over. Snow and/or sleet & rain and/or freezing rain arriving from southwest to northeast by the end of the day. Highs 30-38. Wind N to NE 5-15 MPH.

FRIDAY NIGHT: Overcast with rain except pockets of freezing rain possible interior valley locations evening. Temperatures steady 30-38 evening, rising to 38-45 overnight. Wind N to NE 5-15 MPH, becoming variable.

SATURDAY: Cloudy with areas of fog and a chance of rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind variable 5-15 MPH becoming W.

DAYS 6-10 (JANUARY 3-7)

High pressure noses in with cold/dry weather January 3. We’ll have to watch for low pressure passing south of the region January 4 which is handled very differently by various guidance, but right now my leaning is that it stays far enough south to bring only a minor threat of snow/mix/rain to the South Coast. High pressure brings dry/chilly weather January 5. Weak system may bring clouds and a minor precipitation threat about January 6 before fair weather returns at the end of the period.

DAYS 11-15 (JANUARY 8-12)

Best chances for unsettled weather come about January 8 & 12, but there is a lot of uncertainty with pattern evolution at this time. Will monitor for potential blocking. Not expecting guidance to handle pattern recognition very well for a while.

C-19 Chat Post – December 29 2020

DAYS 1-5 (DECEMBER 28 – JANUARY 1)

The next-to-next-to-next-to-last day of 2020 (today) will be a mild one by late December standards as low pressure tracks east northeastward down the St. Lawrence Valley and a warm front goes by this morning followed by a late-day cold frontal passage. This moisture-starved system will bring only the threat of a rain shower ahead of or along its cold front and despite dominant cloudiness much of the day, we may see some clearing late today. The next-to-next-to-last day of 2020 (Tuesday) will feature a cold wind but dry weather with sun & a few clouds as we’ll be between departing low pressure in eastern Canada and approaching Canadian high pressure. The next-to-last day of 2020 (Wednesday) will be cold but tranquil as high pressure builds over the region, though some high cloudiness will show up. The last day of 2020 (Thursday a.k.a. New Year’s Eve), much like today, will feature lots of clouds and milder air ahead of yet another low pressure area taking a similar track north of our area, and there may be a few rain showers during the day, although these should exit by evening for any limited outdoor festivities taking place that night, just as colder air arrives. The first day of 2021 holds the most complex outlook of this 5-day period, as cold high pressure will have built into eastern Canada while another low pressure area approaches New England from the southwest. Cold air will be stubborn, at least at the surface, as the moisture from this system arrives during the day – a set-up for potential icing conditions and maybe some frozen precipitation, before rain becomes dominant, but all of this will depend on the depth of the cold air and how difficult it is to dislodge. Obviously, fine-tuning will be necessary as this event draws closer.

TODAY: Mostly cloudy through early afternoon then partial sun by late day. Chance of passing rain showers, especially during the afternoon hours. Highs 43-50. Wind S 10-20 MPH.

TONIGHT: Partly cloudy evening. Clearing overnight. Lows 26-31. Wind W 10-20 MPH.

TUESDAY: Sun & passing clouds. Highs 32-39. Wind NW 10-20 MPH.

TUESDAY NIGHT: Clearing. Lows 13-20. Wind NW 5-15 MPH, diminishing.

WEDNESDAY: Sun & high clouds. Highs 33-40. Wind W up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 23-30. Wind S under 10 MPH.

THURSDAY: Mostly cloudy. Chance of rain showers. Highs 45-52. Wind SW 5-15 MPH.

THURSDAY NIGHT (NEW YEAR’S EVE): Mostly cloudy. Lows 28-35. Wind N 5-15 MPH evening, diminishing overnight.

FRIDAY (NEW YEAR’S DAY): Overcast. Rain arriving from southwest to northeast, may begin as freezing rain and/or sleet in some locations. Highs 33-40. Wind N to NE 5-15 MPH.

DAYS 6-10 (JANUARY 2-6)

Low pressure exits during January 2 which starts wet then ends dry & colder. High pressure builds in with dry and cold weather for January 3. Low pressure may pass close to or south of the region with an unsettled weather threat January 4 with the next system likely to be one passing north of the region with milder air and rain showers by January 6, but this being quite a few days away it’s not a high confidence outlook.

DAYS 11-15 (JANUARY 7-11)

Much of this period looks quiet other than a chance of some unsettled weather about January 8. The overall pattern may be shifting to more of a blocking set-up here though which has some potential implications for mid January.

C-19 Chat Post – December 28 2020

DAYS 1-5 (DECEMBER 27-31)

High pressure provides us with bright but cold weather today, and as we come down the home stretch to the finish line of 2020 we’ll be seeing a few more changes in the weather. First, a broad but moisture-starved area of low pressure passes north of our area Monday, dragging its warm front through the region during the morning with lots of cloudiness, then its cold front through in the afternoon with perhaps a rain shower as milder air will have taken over. But quickly behind this comes another shot of cold air between the departing low via eastern Canada and approaching high pressure in the Great Lakes Monday night and Tuesday with a gusty breeze. High pressure will settle over the region then slip to the south with fair and seasonably chilly weather Wednesday. By Thursday, weaker low pressure will travel eastward, passing north of this area but dragging a cold front through. This front may be accompanied by a few rain showers.

TODAY: Mostly sunny. Highs 34-41. Wind W 5-15 MPH becoming variable under 10 MPH.

TONIGHT: Increasing clouds. Lows 25-32. Wind S up to 10 MPH.

MONDAY: Mostly cloudy morning. Partly sunny with a passing rain shower possible afternoon. Highs 43-50. Wind S 10-20 MPH.

MONDAY NIGHT: Partly cloudy evening. Clearing overnight. Lows 26-31. Wind W 10-20 MPH.

TUESDAY: Sun/cloud mix. Highs 34-41. Wind NW 10-20 MPH.

TUESDAY NIGHT: Clearing. Lows 18-25. Wind NW 5-15 MPH.

WEDNESDAY: Sunny. Highs 33-40. Wind W 5-15 MPH, diminishing.

WEDNESDAY NIGHT: Partly cloudy. Lows 23-30. Wind S under 10 MPH.

THURSDAY: Variably cloudy. Chance of rain showers. Highs 45-52. Wind SW 5-15 MPH.

DAYS 6-10 (JANUARY 1-5)

As high pressure builds over eastern Canada and another low travels in our direction from the southwest, what yesterday’s guidance was showing more as a set-up similar to the one we had on Christmas, it now has been leaning toward a little more complex scenario where high pressure to the north is strong enough to force the low’s track a little further south and keep colder air in the region for New Year’s Day. This could be a set-up for a more complex precipitation situation, something we’ll have to keep a close eye on during the next several days. Any precipitation exits by early January 2 followed by dry/colder weather for the January 2-3 weekend. Temperatures moderate with a minor disturbance bringing a chance of mix/rain showers January 4 and/or 5.

DAYS 11-15 (JANUARY 6-10)

Best chances for unsettled weather from passing systems January 8 & 10. Evolution of pattern and storm track is a little uncertain at this time and we’ll be watching for some blocking to potentially set up before the end of this period which could shift the track of future storms more to the south.

COMMENTARY

10 years ago today I published the first blog entry here as we were dealing with a significant winter storm. That was fun, and it’s been an interesting and fun ride since. Thank you everybody who has supported this blog during its first decade of existence!

DAYS 1-5 (DECEMBER 25-29)

Back to seasonably cold weather for this weekend. Today we may see some snow showers making their way all the way across New England via the Great Lakes, so while we have a mixed sky, some of those clouds may release some snowflakes and even brief minor accumulations in some areas. While today is rather blustery, Sunday will end up more tranquil with less wind, more sun, and no snow shower threat. Low pressure will track eastward, passing north of New England early in the week, bringing milder air and clouds in during Monday with a few rain showers, but perhaps a few snow showers west and north of Boston in the evening as colder air returns. Regardless, this will be a minor system and serve mostly to bring a new shot of cold air in for Tuesday, with wind and possibly a passing snow shower, followed by cold but more tranquil weather as high pressure builds in by Wednesday.

TODAY: Sun/cloud mix. Passing snow shower possible, a few of which may result in minor accumulation. Highs 32-39. Wind W 10-20 MPH, higher gusts.

TONIGHT: Clear. Lows 17-24. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 34-41. Wind W 5-15 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 25-32. Wind SW 5-10 MPH.

MONDAY: Variably cloudy. Chance of rain showers. Highs 42-49. Wind SW 10-20 MPH

MONDAY NIGHT: Variably cloudy evening with a rain or snow shower. Clearing overnight. Lows 26-31. Wind W 10-20 MPH.

TUESDAY: Partly cloudy. Chance of a passing light snow shower. Highs 35-42. Wind NW 10-20 MPH.

TUESDAY NIGHT: Clearing. Lows 18-25. Wind NW 5-15 MPH.

WEDNESDAY: Sunny. Highs 33-40. Wind NW 5-15 MPH, diminishing.

DAYS 6-10 (DECEMBER 31– JANUARY 4)

High pressure shifts offshore December 31 with fair and milder weather. Low pressure tracks across southeastern Canada with its frontal system bringing the chance of some rain shower activity here for January 1. Colder/drier January 2-3 followed by moderation and a risk of unsettled weather returning to the region by the end of the period on January 4.

DAYS 11-15 (JANUARY 5-9)

Best chances for unsettled weather from passing systems January 5 & 8. Evolution of pattern and storm track is a little uncertain at this time and we’ll be watching for some blocking to potentially set up before the end of this period which could shift the track of future storms more to the south.
