DAYS 1-5 (DECEMBER 16-20)
Arctic cold keeps its hold on southern New England today with dry weather and gradually diminishing wind as high pressure moves overhead. The rapid progression of weather systems means that a low pressure area will approach the region Saturday, with a large area of overrunning snowfall as milder Pacific air attempts to dislodge the cold air in place, and it will be rather stubborn to go at first, meaning that a moderate accumulation of snowfall may occur in a good portion of the region Saturday morning. As surface temperatures are slow to warm while it does warm up more easily aloft, precipitation will change to rain that will likely freeze on existing snowcover and other surfaces. A plus may be that the precipitation may move out of the region before we have a chance to see much ice accretion. By Saturday evening and the early hours of Sunday, the milder air will finally overtake the region, but it won’t be around along, as a cold front will come chugging along, producing a period of rain showers Sunday morning and midday. If enough moisture hangs around behind the front, the precipitation could end as a mix or snow. What is more certain is that a fairly rapid temperature drop will result in a freeze-up of softened snow and any melt-water and rain water, so by Sunday night and early Monday it may be quite icy in some locations. Monday itself will be a dry and cold day as high pressure moves in. For the time being, it appears that Tuesday will also feature fair but chilly weather.
TODAY: Sun and a few clouds. Highs 15-23. Wind NW 15-30 MPH with higher gusts morning, diminishing during the afternoon.
TONIGHT: Increasing clouds. Snow developing west to east after 2AM. Lows 12-20. Wind light variable.
SATURDAY: Overcast. Snow in the morning changing to rain south to north except freezing rain away from the coast by midday before ending. Snow accumulation before change over 1-2 inches South Coast and Cape Cod, 2-5 inches I-95 corridor to the I-495 belt, 5-8 inches north central MA and southwestern NH. Temperatures rise slowly to around 32 north and near 40 south by the end of the day. Wind S 5-15 MPH.
SATURDAY NIGHT: Mostly cloudy. Spotty drizzle and a slight chance of rain showers. Patchy fog. Temperatures rise into the 40s. Wind S 5-15 MPH.
SUNDAY: Mostly cloudy. Patchy fog early. Rain showers likely morning and midday, may end as mix/snow from northwest to southeast afternoon. Highs 48-55. Wind SW 10-20 MPH morning shifting to NW with higher gusts afternoon.
MONDAY: Mostly sunny. Lows 15-22. Highs 27-34.
TUESDAY: Partly sunny. Lows 12-20. Highs 30-38.

DAYS 6-10 (DECEMBER 21-25)
Low confidence on timing but at the moment it looks like the best chance of a system bringing rain/mix/snow would be later December 22 to early December 23. Mainly dry weather would start and end the period, including the Christmas Holiday and the start of Hanukkah. Temperatures during this period will be closer to seasonal normals.

DAYS 11-15 (DECEMBER 26-30)
A fairly active Pacific jet stream pattern continues with one or two storm threats possible during this period. As is expected this time of year, precipitation type would depend on track and overall set-up, but odds would favor rain as it looks like milder air will dominate with a northward-displaced jet stream in this area.

7:35AM

DAYS 1-5 (DECEMBER 15-19)
Arctic air moves into the region in waves through tonight and hangs on into early Saturday before being pushed out by a Pacific storm system which will bring a swath of snow eventually transitioning to ice/rain Saturday. Still some detail to be worked out regarding this system and will star to do that in the comments below and then have a full breakdown on the next blog entry. By Sunday we’re going to transition the other way from milder to colder again, and that may bring its own set of interesting weather.
TODAY: Sun and clouds. Isolated to scattered snow showers and snow squalls. Any squalls can contain briefly heavy snow and reduced visibility and produce minor accumulation and slippery travel. Highs 24-32 early, then falling temperatures. Wind W to NW 15-30 MPH with higher gusts.
TONIGHT: Partly cloudy. Isolated to scattered snow showers and snow squalls. Lows 0-12. Wind NW 20-30 MPH with gusts 40-60 MPH. Wind chill -10 to -25.
FRIDAY: Mostly sunny to partly cloudy. Isolated snow showers. Highs 14-21. Wind NW 15-30 MPH with higher gusts through early afternoon, diminishing later in the day. Wind chill often below 10.
SATURDAY: Cloudy. Snow developing then transitioning to ice/rain. Lows 10-18. Highs 35-42.
SUNDAY: Mostly cloudy. Rain showers morning to midday may end as snow.. Temperature 45-55 early, then falling.
MONDAY: Mostly sunny. Lows 10-18. Highs 25-33.

DAYS 6-10 (DECEMBER 20-24)
Still have watch this period for 1 or 2 potential low pressure systems bringing precipitation threats. Temperatures a little closer to seasonable overall.

DAYS 11-15 (DECEMBER 25-29)
A weak disturbance bring the chance of rain/snow showers around Christmas and a more important system may approach later in the period.

2:20AM

DAYS 1-5 (DECEMBER 14-18)
A weak disturbance will exit the region this morning after producing spotty light snow/rain over southeastern MA and RI. A couple of arctic boundaries will cross southern New England from northwest to southeast during Thursday, possibly producing snow showers/squalls. The main story will be the strong wind and bitterly cold air that moves in with these boundaries and continues through Friday, though the wind will drop off later Friday. The very progressive pattern will drive the next storm system into the region from the west early in the weekend, but its sprawling nature means it may take much of the weekend to get through here, bringing a transition out of the late-week cold to a milder spell, then back to cold at the very end, with a variety of weather during it all.
TODAY: Cloudiness decreases and sunshine develops after a little spotty light snow/rain in eastern MA and RI early. Highs 38-45. Wind W 5-15 MPH
TONIGHT: Clear evening. Partly cloudy with isolated to scattered snow showers overnight. Lows 22-30. Wind W 5-15 MPH.
THURSDAY: Sun and clouds. Isolated to scattered snow showers and snow squalls. Any squalls can contain briefly heavy snow and reduced visibility and produce minor accumulation and slippery travel. Highs 24-32 early, then falling temperatures. Wind W to NW 15-30 MPH with higher gusts.
THURSDAY NIGHT: Partly cloudy. Isolated to scattered snow showers and snow squalls. Lows 0-12. Wind NW 15-30 MPH with gusts over 40 MPH. Wind chill -10 to -25.
FRIDAY: Mostly sunny to partly cloudy. Isolated snow showers. Highs 14-21. Wind NW 15-30 MPH with higher gusts through early afternoon, diminishing later in the day. Wind chill often below 10.
SATURDAY: Clouding up early. Snow developing then transitioning to ice/rain. Lows 10-18. Highs 35-42.
SUNDAY: Mostly cloudy. Rain showers morning to midday. Temperature 45-55 morning-midday falling later.

DAYS 6-10 (DECEMBER 19-23)
Fair and cold December 19. Watch the period December 20-23 for 1 or possibly 2 precipitation threats from potential passing storms.

DAYS 11-15 (DECEMBER 24-28)
A couple weak disturbances bring the chance of rain/snow showers around Christmas and a more important system may approach later in the period.

7:34AM

DAYS 1-5 (DECEMBER 13-17)
Pattern remains very progressive with weak high pressure to the south of the region today giving way to a developing area of low pressure passing south of the region tonight and early Wednesday. Energy between this and another low over the Great Lakes will bring some cloudiness into the region by tonight to very early Wednesday with just a touch of light snow possible. Then, a couple arctic cold fronts bring much colder and windy weather in for Thursday and Friday. By Saturday, temperatures moderation is underway but this will be introduced by a period of snow to ice to rain as the warmer air has to overrun the cold air in place as it moves in.
TODAY: Increasing clouds. Highs 34-42. Wind W 5-15 MPH.
TONIGHT: Mostly cloudy. Spotty light snow. Lows 22-30. Wind SW 5-10 MPH.
WEDNESDAY: Mostly cloudy morning with spotty light snow early. Mostly sunny afternoon. Highs 33-41. Wind W 10-20 MPH.
THURSDAY: Variably cloudy. Scattered snow showers/squalls. Windy. Temperatures fall through the 20s.
FRIDAY: Mostly sunny. Windy. Lows 0-8 except 9-14 Cape Cod. Highs 17-25.
SATURDAY: Clouding over. Snow to ice to rain. Lows 8-16. Highs 38-45.

DAYS 6-10 (DECEMBER 18-22)
Milder with rain showers December 18. Colder December 19-21 but may have to watch a wave of low pressure passing to the south about December 20 with a possible snow threat. Milder with a few rain/snow showers at the end of the period.

DAYS 11-15 (DECEMBER 23-27)
Weak systems may bring a few rain/snow showers early to mid period. Watch for a stronger system late period. Temperatures variable but averaging closer to normal overall.

1:26AM

DAYS 1-5 (DECEMBER 12-16)
We start the week with a weak but somewhat significant system, weak in terms of its strength, but significant in terms of its impact on the morning commute, as snow will be in the process of transitioning to rain from south to north across the region, with a period of freezing rain over north central MA and southern NH for a while. The snow is expected to have accumulated less than 1 inch across far southeastern MA, southern RI, and the immediate coast of eastern MA, with 1-3 inches in the I-95 belt, 2-4 inches in the I-495 belt, and 3-6 inches from north central MA into southwestern and south central NH. By midday and afternoon it’s a done deal and the sky will be clearing for tonight’s Monday Night Football game in Foxboro between the Patriots and Ravens. In fact, with not too much cold air behind the storm, it won’t be all that bad for player and spectators. Expected dry weather Tuesday with a seasonable chill, then changes start to take place. Wednesday, a storm system will develop but should pass south of the region. We’ll have to watch for a period of cloudiness and perhaps a little snow/mix near the South Coast, but for now going with the idea of it staying too far south. This storm system will turn more to the north once by the region and combine with another low into a stronger system in the Canadian Maritimes, helping to drag down some very cold air for Thursday and Friday. A couple disturbances may result in snow showers/squalls Thursday afternoon and night. Expect a lot of wind as well on Thursday and Friday.
TODAY: Overcast into afternoon with rain southern MA/RI/CT and snow transitioning to rain northern MA into southern NH but with a period of sleet and freezing rain possible north central MA into interior southern NH, then rain ending from west to east midday and early afternoon. Breaking clouds late day. Highs 38-46 late-day. Wind variable under 10 MPH becoming W 5-15 MPH.
TONIGHT: Clearing. Patchy black ice on untreated surfaces. Lows 23-31. Wind W 5-15 MPH.
TUESDAY: Partly cloudy. Highs 34-42. Wind W 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Lows 22-30. Wind SW 5-10 MPH.
WEDNESDAY: Mostly cloudy southeastern areas morning, otherwise partly cloudy. Highs 33-41. Wind W 10-20 MPH.
THURSDAY: Variably cloudy. Scattered snow showers/squalls. Windy. Temperatures fall through the 20s.
FRIDAY: Mostly sunny. Windy. Lows 0-8 except 9-14 Cape Cod. Highs 17-25.

DAYS 6-10 (DECEMBER 17-21)
Developing snow to mix to rain December 17 with a very cold start and less cold finish. Much milder with rain showers possible December 18. Generally dry and colder December 19-21.

DAYS 11-15 (DECEMBER 22-26)
Weak systems may bring a few rain/snow showers early and mid period. Temperatures variable but averaging closer to normal overall.

8:19AM

DAYS 1-5 (DECEMBER 11-15)
The active pattern will continue. This is not a pattern juiced with big storms, but a pattern with frequent systems and changing weather. First, a cold and dry Sunday as clouds increase ahead of the approaching low pressure area that you’ve heard about as if it’s some massive winter storm about to strike. Truth is, as far as winter-type storm systems go, it’s rather minor. Once again it’s timing as well as precipitation type that will have impact on travel. That critical time will be the Monday morning drive as snow will have fallen in much of the region starting several hours before that. The forecast is essentially unchanged from yesterday, so I’ll leave it at that. Looking ahead, there are also no significant changes to the thinking presented on the previous blog update. Tuesday will be fair and chilly as a small high pressure area crosses the region. Keeping Wednesday’s forecast mainly dry for now as systems should be weak enough and far enough apart well south and northwest that we’re in between and left with nothing. What will happen is the southern system will intensify off the Mid Atlantic as it turns more to the north, eventually joining with the northern system to form a larger storm and yank down much colder air from Canada starting Thursday.
TODAY: Sunshine fading behind increasing clouds. Highs 28-36. Wind light variable.
TONIGHT: Thickening overcast. Snow develops overnight except mix South Coast. Lows 22-30. Wind light NE to E.
MONDAY: Overcast. Precipitation morning to early afternoon will be mainly snow I 495 north of the Mass Pike and northwestward from there but may end as a period of sleet/freezing rain near I 495 and in parts of central MA to far southern NH, snow transitioning to mix then rain I 95 belt mainly Boston to Providence corridor, mix turning to rain immediate coast from Boston south including Cape Cod. Updated snow accumulation estimate: coating to 1 inch coastline and Cape Cod, 1-3 inches Boston to Providence corridor, 3-6 inches I 495 belt mainly north of the Mass Pike and northwestward from there. Highs 33-43, mildest Cape Cod. Wind variable 5-15 MPH.
TUESDAY: Partly cloudy. Lows 22-30. Highs 32-40.
WEDNESDAY: Variably cloudy. Lows 20-28. Highs 34-42.
THURSDAY: Partly cloudy. Chance of snow showers. Windy. Lows 15-23. Highs 28-35 early but falling after.

DAYS 6-10 (DECEMBER 16-20)
Fair and very cold December 16. Unsettled over the weekend of December 17-18 with a threat of snow/mix/rain depending on evolution of 1 or 2 low pressure areas. Fair and colder at the end of the period.

DAYS 11-15 (DECEMBER 21-25)
From the Winter Solstice to Christmas Day expect a fast-flowing pattern with a couple minor systems and variable temperatures averaging a little closer to normal.

2:47AM

DAYS 1-5 (DECEMBER 10-14)
Active pattern upcoming as the fast-moving Pacific jet stream pattern continues, but now sharing itself with some colder air pressing southward out of Canada, which makes things a little more interesting. After a fair and cold Saturday and most of Sunday, the next plume of Pacific moisture will arrive with a elongated wave of low pressure Sunday night into Monday. The question continues to be where the snow/mix/rain zones will be, and the best call at this point is to go with snow to start in most areas except mix South Coast Sunday night, then the mix/rain area moving northward to at least the Mass Pike area and Boston-Providence corridor during Monday morning, but how fast and to what position will determine how much snow falls. For now will lean to mainly snow for the duration in the I 495 belt north of the Mass Pike with the mix/rain zone getting into the I 95 corridor toward the end of the event, with more rain further southeast. All of this will be out of here by Monday evening in time for an 8:30PM kick off in Foxboro of Monday Night Football between the Patriots and Ravens. Tuesday will be fair and chilly as a small high pressure area crosses the region. Wednesday will bring the next risk of precipitation but at this point it looks as if it may end up being two systems that never really get too involved with each other, one passing south and the other to the north, so while it is still several days off just going with a risk of snow showers for now.
TODAY: Mostly sunny. Highs 27-35. Wind NW 10-20 MPH with higher gusts morning, diminishing afternoon.
TONIGHT: Clear. Lows 9-15 outlying areas, 16-24 elsewhere. Wind light variable.
SUNDAY: Sunshine fading behind increasing clouds. Highs 28-36. Wind light variable.
SUNDAY NIGHT: Thickening overcast. Snow develops overnight except mix South Coast. Lows 22-30. Wind light NE to E.
MONDAY: Overcast. Precipitation morning to early afternoon will be mainly snow I 495 north of the Mass Pike and northwestward from there but may end as brief mix near I 495, snow transitioning to mix and ending as mix and rain I 95 belt mainly Boston to Providence corridor, mix turning to rain immediate coast from Boston south including Cape Cod. Preliminary snow accumulation estimate: coating to 1 inch coastline and Cape Cod, 1-3 inches Boston to Providence corridor, 3-6 inches I 495 belt mainly north of the Mass Pike and northwestward from there. Highs 33-43, mildest Cape Cod. Wind variable 5-15 MPH.
TUESDAY: Partly cloudy. Lows 22-30. Highs 32-40.
WEDNESDAY: Variably cloudy. Risk of snow showers. Lows 20-28. Highs 32-40.

DAYS 6-10 (DECEMBER 15-19)
Confidence remains lower than average overall but am pretty sure of a blast of cold air early in the period and a storm threat around the weekend of December 17-18.

DAYS 11-15 (DECEMBER 20-24)
Another storm threat may occur about the middle of the period but again highly subject to change based on the fast-flowing pattern and medium range guidance difficulty in the solution of possible systems.

7:33AM

DAYS 1-5 (DECEMBER 9-13)
First, the cold and wind today into Saturday. The cold lingers Sunday as an area of moisture approaches from the west but runs into dry air. Clouds will increase but the snow risk will be limited initially and have to wait for the main push of moisture with approaching low pressure by Monday, which will bring snow at least at first. The question is where the mix/change line ends up. For now will go for it pushing northward into much of the region but it may end up colder and further south. So Monday’s forecast is currently low confidence.
TODAY: Partly cloudy. Highs 34-42. Wind W 15-25 MPH with higher gusts.
TONIGHT: Mostly clear. Lows 16-25. Wind NW 15-25 MPH with higher gusts. Wind chill below 10 at times.
SATURDAY: Mostly sunny. Highs 27-34. Wind NW 15-25 MPH with higher gusts, diminishing in the afternoon.
SUNDAY: Increasing clouds. Chance of very light snow in the afternoon. Lows 13-21. Highs 30-38.
MONDAY: Cloudy. Snow likely then rain/mix line pushing northward at least part-way through the region. Lows 26-34. Highs 32-42 north to south.
TUESDAY: Partly sunny. Chance of snow showers. Windy. Lows 15-23. Highs 30-38.

DAYS 6-10 (DECEMBER 14-18)
Next system brings a chance of snow/mix/rain December 14 depending on track. Snow showers possible and much colder December 15-16. Fair and cold December 17. Next system brings a precipitation threat December 18.

DAYS 11-15 (DECEMBER 19-23)
No major changes to the overall pattern. Period likely starts and ends somewhat unsettled but this pattern makes it difficult to time and figure out track of systems more than a couple days in advance so much fine tuning to be done here.

7:16AM

DAYS 1-5 (DECEMBER 8-12)
The approach today will be a little bit old school as I’m currently not really trusting any computer models that much. Risky perhaps, but here goes my best shot at what I think will take place in the coming days. The next 3 will feature a west to northwest flow and a colder trend, with the coldest air of the season arriving later Friday into Saturday. The dominant Pacific jet stream will send an area of moisture this way during Sunday, bringing a chance of snow, favoring late day. How this system evolves is uncertain, but Monday will likely be an unsettled day with a risk of rain/mix/snow depending on location. There is plenty of time to work out these details.
TODAY: Partly sunny. Highs 38-45. Wind light variable early, then W increasing to 10-20 MPH and gusty.
TONIGHT: Mostly clear. Lows 24-30. Wind W 10-20 MPH with higher gusts.
FRIDAY: Partly cloudy. Highs 35-42. Wind W 15-25 MPH with higher gusts.
FRIDAY NIGHT: Mostly clear. Lows 18-25. Wind NW 15-25 MPH with higher gusts. Wind chill below 10 at times.
SATURDAY: Mostly sunny. Highs 27-34. Wind NW 15-25 MPH with higher gusts, diminishing in the afternoon.
SUNDAY: Increasing clouds. Chance of snow by late day. Lows 13-21. Highs 30-38.
MONDAY: Cloudy. Risk of snow/mix/rain. Lows 26-34. Highs 34-42.

DAYS 6-10 (DECEMBER 13-17)
Low confidence on timing of systems. At this time it appears one Pacific jet stream system will depart early in the period, a second one will threaten snow/mix about mid period, and another may approach by the very end of the period. Will refine this in future posts. A significant cold shot is possible around December 15-16.

DAYS 11-15 (DECEMBER 18-22)
No major changes to the overall pattern. Will work on the timing of systems.

7:31AM

DAYS 1-5 (DECEMBER 7-11)
In between storms well north and well south today but still unsettled. The snow fell mostly outside 495 in the early morning hours with rain further east and now we just have lingering lighter precipitation that will taper off. Thursday through Saturday will be mainly dry, rather windy, and trend colder. The next storm approaches later Sunday and if it gets here soon enough will bring some snow.
TODAY: Mostly cloudy. Patchy fog. Spotty light mix/rain mainly morning and midday. Highs 38-45. Wind variable up to 15 MPH.
TONIGHT: Partly cloudy. Watch for areas of black ice. Lows 25-33. Wind light W.
THURSDAY: Variably cloudy. Risk of a passing rain shower. Highs 38-45. Wind 5-15 MPH increasing to 15-25 MPH late.
FRIDAY: Partly cloudy. Windy. Risk of a passing snow shower. Lows 25-32. Highs 35-42.
SATURDAY: Mostly sunny. Windy. Lows 15-23. Highs 27-34.
SUNDAY: Increasing clouds. Chance of snow late. Lows 15-23. Highs 33-40.

DAYS 6-10 (DECEMBER 12-16)
Unsettled weather continues with a possible mix of precipitation December 12. Watching for another possible precipitation threat about December 14 then a shot of windy/cold weather following that.

DAYS 11-15 (DECEMBER 17-21)
Another storm threat early to mid period. Odds favor a milder track at this point.

7:27AM

DAYS 1-5 (DECEMBER 6-10)
Watch for patches of black ice this morning! Otherwise, a decent day today with high pressure providing sunshine with a seasonable chill. The next system arrives late tonight and as stated in the previous update will be a split system with one low north of the Great Lakes and another passing well south of New England Wednesday, leaving us in the middle with a little light precipitation, but it may be just enough in the form of snow to create a bit of a slick road situation especially over the interior prior to the Wednesday morning commute. Still looks like Thursday’s threat evolves mainly after it goes by, so just looking for some rain to snow showers as colder air arrives. The shot of cold air will be more pronounced Friday and Saturday as we get a piece of early-season Arctic air pulled out of Canada.
TODAY: Sunshine, then increasing clouds later. Highs 38-45. Wind light variable.
TONIGHT: Cloudy. Brief light snow to mix northwest, mix/rain southeast overnight. Lows 30-38. Wind light SE.
WEDNESDAY: Mostly cloudy. Spotty light mix/rain mainly morning. Highs 38-45. Wind variable up to 15 MPH.
THURSDAY: Variably cloudy. Risk of rain to snow showers. Lows 28-35. Highs 36-43.
FRIDAY: Partly cloudy. Windy. Snow showers mainly morning. Lows 25-32. Highs 35-42.
SATURDAY: Mostly sunny. Windy. Lows 15-23. Highs 27-34.

DAYS 6-10 (DECEMBER 11-15)
Next storm threat comes later December 11 through early December 13. This may be rain, mix, or snow, depending on low pressure track. Details to be worked out. Another system may threaten December 14 or 15.

DAYS 11-15 (DECEMBER 16-20)
One or two precipitation threats from passing Pacific jet stream low pressure areas. Temperatures highly variable.

2:40AM

DAYS 1-5 (DECEMBER 5-9)
Why waste time? Let’s start the work week off with a bit of a tricky commute. The cause? Snow from a fairly weak low pressure area moving through the Northeast today. The worst areas? The initial burst of snow between 5AM and 8AM will move west to east and impact southern NH, central and parts of eastern MA most significantly, but not because of the amount of snow. In reality, accumulations will be rather small. But because of a cold night and early morning, snow that falls can lightly coat any surfaces rather quickly and make them quick slippery. Temperatures are marginal further southeast and a slightly later arrival of precipitation there will mean much less of an impact. By noon, it’s pretty much a done deal and anything left will be a mix/rain except still a pocket of snow possible in north central MA and southern NH before everything moves out. A break in the unsettled weather will be brief on Tuesday as another low pressure are will be heading in for Tuesday night and Wednesday, but this one, an elongated area, will be weakening as it moves in, with the main areas of energy really staying both northwest and south of the region. It will also be a little milder with the next system, so mix/rain is more likely than snow. And then we do it again Thursday and Thursday night as another area of energy coming along the jet stream ignites a low pressure system. This one will probably not get its act together until it gets just beyond the region, so look for rain/mix developing Thursday and probably ending as lingering snow showers Friday as we get a shot of much colder air moving into the region behind this departing system.
TODAY: Cloudy through early afternoon with a period of snow mainly northwest of a Boston-Providence line accumulating a coating to 2 inches, highest amounts in higher elevations of north central MA and southern NH and possibly interior northeastern MA, then a mix of rain/snow further southeast a bit later, changing to rain, with a mix to rain area coming northward across eastern MA while it remains mostly snow for a while to the northwest, before tapering off midday and early afternoon. Clouds may break for a little sun late day. Highs 35-43. Wind variable 5-15 MPH.
TONIGHT: Clearing. Lows 22-30. Watch for patchy icy spots where snow melted but surfaces did not dry off. Wind light NW.
TUESDAY: Increasing clouds. Highs 38-45. Wind light variable.
TUESDAY NIGHT: Cloudy. Brief light snow to mix northwest, mix/rain southeast overnight. Lows 30-38. Wind light SE.
WEDNESDAY: Mostly cloudy. Spotty light mix/rain mainly morning. Highs 38-45. Wind variable up to 15 MPH.
THURSDAY: Mostly cloudy. Risk of afternoon rain, nighttime mix. Lows 28-35. Highs 36-43.
FRIDAY: Partly cloudy. Windy. Snow showers mainly morning. Lows 25-32. Highs 35-42.

DAYS 6-10 (DECEMBER 10-14)
Fair and cold December 10. The period December 11-13 will likely see some impact from 1 or 2 low pressure areas – details uncertain. Fair weather returns to end the period with another shot of cold air.

DAYS 11-15 (DECEMBER 15-19)
One or two precipitation threats from passing Pacific jet stream low pressure areas. Temperatures highly variable.

11:30AM

DAYS 1-5 (DECEMBER 4-8)
High pressure provides a nice December day to round out the first weekend of the final month of 2016. Winds which were brisk during the morning will relax during the afternoon. Things change quick around here, and clouds will sneak in tonight ahead of a weak area of low pressure that will pass just south of the region Monday, bringing a period of generally light precipitation, falling as mostly snow north and west of Boston, snow to mix/rain Boston area south. Look for minor snow accumulation (details below). Another slightly stronger low pressure area will approach Tuesday night and move into the region Wednesday but will be weakening as it does this, and with a little milder air in place, this one will be mostly mix/rain. Another low will try to form nearby Thursday. If it does so quickly enough, a period of rain to snow cannot be ruled out, but I believe it will evolve just far enough east to really bring just rain and snow showers to the region as colder air arrives.
TODAY: Sunny. Highs 37-44. Wind N 5-15 MPH with higher gusts, diminishing gradually.
TONIGHT: Increasing clouds. Snow arrives southwestern NH and central MA pre-dawn. Lows 22-27 except 28-33 immediate coast. Wind light variable.
MONDAY: Cloudy through mid afternoon with snow north and west of Boston amounting to a coating to 2 inches, greatest in higher elevations of north central MA to southwestern NH including Worcester and Fitchburg MA and Jaffrey NH. Snow/mix likely turning to rain from Boston/Providence southeastward with little or no accumulation. Clouds break late-day especially west of Boston. Highs 35-42. Wind variable 5-15 MPH shifting to N late.
MONDAY NIGHT: Slow clearing. Watch for icy patches on untreated surfaces. Lows 23-32. Wind light N to NW.
TUESDAY: Increasing clouds. Highs 40-48. Wind light variable.
WEDNESDAY: Cloudy with light mix/rain. Lows 30-38. Highs 38-45.
THURSDAY: Mostly cloudy with rain/snow showers. Lows 32-40. Highs 40-48 but may turn much colder late.

DAYS 6-10 (DECEMBER 9-13)
Cold, windy, isolated snow showers Friday December 9. Fair, cold, but diminishing wind Saturday December 10. Next storm system threatens later December 11 into December 12, but track/timing uncertain at this point. Fair by the end of the period.

DAYS 11-15 (DECEMBER 14-18)
Milder overall, a couple Pacific systems may threaten with rain/mix during this period.

3:33AM

DAYS 1-5 (DECEMBER 3-7)
High pressure center west of the region send a cooling northwesterly flow into the region for the weekend with fair weather. A weak disturbance will pass through during the first half of Monday and may bring a few insignificant snow showers. A couple low pressure areas will approach from the southwest late Tuesday but will be weakening as they move through on Wednesday with insignificant rainfall.
TODAY: Sun and patchy clouds. Highs 40-48. Wind NW 10-20 MPH with higher gusts.

DAYS 6-10 (DECEMBER 8-12)
Another low pressure area arrives from the west early in the period with a rain threat, but its departure will be followed by a blast of colder air December 9-10 with no more than a few snow showers but mainly dry weather. Fair and more tranquil by December 11 but the next Pacific low may bring unsettled weather by the end of the period.

DAYS 11-15 (DECEMBER 13-17)
Similar pattern with 1 or 2 Pacific jet stream lows bringing a risk of precipitation. Some models have hinted at cold enough for snow for one of these but it’s too early to know for sure. I’d lean milder at this point.
