DAYS 1-5 (DECEMBER 28 – JANUARY 1)

Today is transition day as high pressure slips off the East Coast and a clipper system travels to our north. We’ll see lots of clouds and slightly milder air. Thursday and Friday will be fair and mild late December days with high pressure firmly established off the US East Coast. As we approach the time to flip the calendar, it will turn unsettled over the weekend that takes place. Clouds will dominate Saturday as a frontal boundary approaches from the west. There is some question as to how much rain will make it into the region that day. I will include the chance of passing rain showers for now, holding off much of the rainfall until later at night, possibly before midnight, and into a portion of the first day of 2023 before low pressure pulls a frontal boundary to our east and drier air arrives. Some fine-tuning will be needed for the weekend (New Year’s Eve / New Year’s Day) forecast.

TODAY: Mostly cloudy morning. Sun/cloud mix afternoon. Highs 35-42. Wind SW 5-15 MPH.

TONIGHT: Mostly clear. Lows 21-28. Wind SW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 40-47. Wind SW up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 20-27. Wind SW up to 10 MPH.

FRIDAY: Partly sunny. Highs 45-52. Wind SW 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Lows 32-39. Wind S up to 10 MPH.

SATURDAY: Mostly cloudy. A rain shower possible. Highs 47-54. Wind S 5-15 MPH.

SATURDAY NIGHT: Cloudy. Rain showers possible during the evening. Rain likely overnight. Lows 40-47. Wind S 5-15 MPH.

SUNDAY: Cloudy with rain likely in the morning. Breaking clouds afternoon. Areas of fog. Highs 50-57. Wind S 5-15 MPH shifting to W with higher gusts by late in the day.

DAYS 6-10 (JANUARY 2-6)

During the first several days of the new year we will sit near a boundary between mild air to the south and east and cooler to colder air to our north and northwest, leaving us vulnerable to a couple unsettled weather systems. It’s too early to really try timing the unsettled weather precisely, but eyeing January 4 and 6 as higher potentials.

DAYS 11-15 (JANUARY 7-11)

A similar pattern to what’s expected in the 6-10 day period continues to keep us in the zone for a couple of precipitation events with variable temperatures, averaging near to above normal.

DAYS 1-5 (DECEMBER 27-31)

The final 5 days of 2022 are covered in this first section of the blog and we’ll have a fairly quiet pattern during this stretch of time. The main feature will be a gradual warming trend as high pressure becomes established off the East Coast. Several other things will be going on – none of them major. First, clouds start today as a disturbance move through the region, but its departure will allow for sun to follow the clouds. A clipper low will track north of our region early to midday Wednesday with more cloudiness, but will keep an area of snow and snow showers to our north (delivering some accumulation to the mountains). Fair weather is expected otherwise through Friday and into Saturday, but clouds will advance into the region on Saturday ahead of a frontal boundary. I cannot rule out some rain shower activity in the region before Saturday is over, but at the moment I expect this to hold off for most areas until at least sometime after dark. They may be a factor for those out and about to celebrate the coming of the new year. Will fine-tune as we get closer.

TODAY: A cloudy start, then slow clearing. Highs 30-37. Wind W 5-15 MPH.

TONIGHT: Mostly clear evening. Clouds return overnight. Lows 18-25. Wind SW up to 10 MPH.

WEDNESDAY: Mostly cloudy morning. Sun/cloud mix afternoon. Highs 35-42. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 21-28. Wind SW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 40-47. Wind SW up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 20-27. Wind SW up to 10 MPH.

FRIDAY: Partly sunny. Highs 45-52. Wind SW 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Lows 32-39. Wind S up to 10 MPH.

SATURDAY: Mostly cloudy. A rain shower possible. Highs 47-54. Wind S 5-15 MPH.

DAYS 6-10 (JANUARY 1-5)

Low pressure moving through the region is expected to provide a wet and mild start to 2023, followed by fair and slightly cooler weather, then another disturbance with mild and rain showery weather around January 4, exiting quickly thereafter in a progressive pattern.

DAYS 11-15 (JANUARY 6-10)

Watching the January 6-8 window for potential unsettled weather which can be in any form from rain to ice to snow as we’ll be near the border of mild air along the East Coast and colder air from Canada. Drier, seasonably chilly weather follows.

DAYS 1-5 (DECEMBER 26-30)

A fairly quiet final stretch of 2022 this week, starting cold, ending mild as high pressure shifts to a position off the East Coast over the coming days. Only a weak disturbance passing by tonight may bring with it a few light snow showers to portions of the region.

TODAY: Sun followed by clouds. Highs 26-33. Wind W up to 10 MPH.

TONIGHT: Lots of clouds. A possible snow flurry favoring southern NH and northern MA. Lows 18-25. Wind W up to 10 MPH.

TUESDAY: Early clouds then sunny. Highs 28-35. Wind W up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 15-22. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 35-42. Wind W 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 20-27. Wind SW up to 10 MPH.

FRIDAY: Partly sunny. Highs 45-52. Wind SW 5-15 MPH.

DAYS 6-10 (DECEMBER 31 – JANUARY 4)

A mild end to 2022 with high pressure offshore and a trough approaching from the west, which may bring some wet weather before the final minutes of the year are counted down. Most likely unsettled days of early 2023 are January 1 and 4 based on current projected timing of disturbances in a generally west to east flow. Coolest weather January 2-3, but no severe cold.

DAYS 11-15 (JANUARY 5-9)

One or two relatively minor systems with precipitation threats during this period with a generally west to east flow. Variable temperatures averaging near to above normal.

Here ’tis.

DAYS 1-5 (DECEMBER 25-29)

Merry Christmas! We will have a quiet but cold holiday overall. A snow band that has dropped several inches of snow over Martha’s Vineyard and up to a few inches along parts of the South Coast will fade away during the day. Otherwise, high pressure will bring fair, cold weather today into the early portion of the week with a moderation in temperature following that.

TODAY (CHRISTMAS): Snow showers with additional light accumulation Islands to South Coast, diminishing by midday, otherwise partly cloudy to mostly sunny. Highs 23-30. Wind W 5-15 MPH.

TONIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 26-33. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 13-20. Wind WSW up to 10 MPH.

TUESDAY: Partly cloudy. Highs 28-35. Wind SW 5-15 MPH shifting to NW.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 32-39. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 18-25. Wind variable up to 10 MPH.

THURSDAY: Mostly sunny. Highs 38-45. Wind SW up to 10 MPH.

DAYS 6-10 (DECEMBER 30 – JANUARY 3)

Fair and mild weather is expected with high pressure off the Atlantic Coast for the final couple days of 2022. Unsettled weather, likely rain or rain showers, with low pressure and a frontal system moving through the region to greet 2023, followed by dry and somewhat cooler weather.

DAYS 11-15 (JANUARY 4-8)

One or two relatively minor systems with precipitation threats during this period with a generally west to east flow. Variable temperatures averaging near to above normal.

DAYS 1-5 (DECEMBER 24-28)

Christmas Weekend will be a cold one, and mainly dry, behind the big storm. Today will be the windier of the the two days, and some ocean-effect snow is expected along the South Coast, especially Cape Cod and the Islands. Otherwise, generally dry weather is expected with only the remote chance of a few snow flurries making their way into the region via the Great Lakes. Cold weather eases up slightly but generally continues into early next week. Watching for a disturbance with a snow shower threat about Tuesday.

TODAY: Sun/cloud mix. Isolated to scattered snow showers possible, especially South Coast. Snow accumulation of up to 3 inches islands, especially Martha’s Vineyard, and up to 1 inch South Coast especially Cape Cod. Highs 20-27. Wind SW 15-25 MPH, higher gusts. Wind chill around 10.

TONIGHT (CHRISTMAS EVE): Partly cloudy. Isolated snow showers, but additional scattered snow showers in the South Coast region. Lows 12-19. Wind WSW 10-20 MPH. Wind chill below 10.

SUNDAY (CHRISTMAS): Mostly sunny. Slight chance of an isolated light snow shower. Highs 23-30. Wind W 5-15 MPH, higher gusts. Wind chill below 20.

SUNDAY NIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 26-33. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 13-20. Wind WSW up to 10 MPH.

TUESDAY: Partly sunny. Chance of snow showers. Highs 28-35. Wind SW 5-15 MPH shifting to NW.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 32-39. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 29 – JANUARY 2)

Temperature moderation heading through the last few days of 2022 with fair weather as high pressure moves off the coast, after which we get into some unsettled weather – likely rain, as a frontal system and low pressure area move through the region, to start the new year.

DAYS 11-15 (JANUARY 3-7)

A bit of an up and down temperature pattern during this period with a battle between the Southeast ridge and high pressure in eastern Canada seems to be shaping up. Typical La Nina pattern. Too soon to time any disturbances / unsettled weather.

DAYS 1-5 (DECEMBER 23-27)

The long-advertised storm is in progress, and behaving as expected with no surprises thrown at us. Expect some coastal flooding and additional wind damage with potential power outages especially in RI and eastern MA to the NH Seacoast region where wind gusts are strongest through mid morning, with coastal flooding issues through the late morning high tide cycle. The lull is on the way and then we get one or two more rounds of rain squalls in the area this afternoon as the cold front extending from rapidly deepening low pressure in the Great Lakes passes by. As the low lifts into eastern Canada through tonight, an arctic boundary will pass by and may produce some snow showers and even a brief snow squall in some areas. While we miss a widespread flash freeze due to the wind’s ability to dry many surfaces before temperatures fall rapidly below freezing, we still will have icy patches and also some scattered coatings of snow which can also briefly slick up some surfaces. But the ongoing wind and much drier air should sublimate much of the ice into morning – but use caution regardless. Wind chill becomes the deal for Saturday, and while most of the region is dry with just a slight chance of a passing snow flurry, the South Coast will see some ocean-effect snow which likely delivers a small accumulation. Christmas Eve and Christmas Day continue to be generally dry and quite cold, though the wind will start to settle down moving through Christmas Day and any lingering ocean effect snow showers will push away from the South Coast, leaving only the slightest chance of a snow flurry from Great Lakes snow shower remnants. High pressure brings dry and chilly weather Monday, and a weak disturbance may produce a few snow showers Tuesday as it moves through from west to east.

TODAY: Overcast morning with rain and embedded heavier rain showers with a slight chance of thunder, diminishing from southwest to northeast. Mostly cloudy midday and early afternoon with isolated showers and even a break of sun possible. Then heavier clouds and 1 or 2 rounds of moderate to heavy rain showers moving through from southwest to northeast through mid afternoon, again a slight chance of thunder. Clouds may break for a glimpse of sun, especially near and west of I-95, prior to sunset. Snow showers are possible central MA, southwestern NH, and eastern CT late day. Highs 53-60 this morning, falling to the 40s this afternoon. Wind SE 15-35 MPH, gusts 40+ MPH inland, 50+ MPH coastal areas, diminishing for a while, then shifting to SW at similar speeds but a shorter period of strong gusts through mid afternoon.

TONIGHT: Variably cloudy evening with snow showers possible – minor accumulation may occur. Rapid icing over of any wet surfaces. Partly cloudy overnight with additional snow showers developing South Coast. Lows 12-19. Wind SW 15-30 MPH with higher gusts. Wind chill below 10.

SATURDAY: Sun/cloud mix. Isolated to scattered snow showers possible, especially South Coast. Snow accumulation of up to 2 inches island and up to 1 inch South Coast. Highs 20-27. Wind SW 15-25 MPH, higher gusts. Wind chill around 10.

SATURDAY NIGHT (CHRISTMAS EVE): Partly cloudy. Isolated snow showers, but additional scattered snow showers in the South Coast region. Lows 12-19. Wind WSW 10-20 MPH. Wind chill below 10.

SUNDAY (CHRISTMAS): Partly cloudy. Isolated snow showers. Highs 23-30. Wind W 5-15 MPH, higher gusts. Wind chill below 20.

SUNDAY NIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 26-33. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 13-20. Wind WSW up to 10 MPH.

TUESDAY: Partly sunny. Chance of snow showers. Highs 28-35. Wind SW 5-15 MPH shifting to NW.

DAYS 6-10 (DECEMBER 28 – JANUARY 1)

Quiet and cold middle of next week followed by moderation in temperature as we approach the change of year. May see wet weather to greet 2023, based on current timing and a more progressive Pacific-driven pattern evolving.

DAYS 11-15 (JANUARY 2-6)

May start with a bit of wet weather then drier and a cool down followed by moderation again and potential unsettled weather by the end of the period. Far too soon for any detail, but the overall pattern looks somewhat benign for early January.

DAYS 1-5 (DECEMBER 22-26)

On this first full day of winter, we look at the details of an upcoming storm. First we see clouds advance and thicken up today ahead of the system. Low pressure tracks into and through the Great Lakes while rapidly deepening through Friday. Between that and a strengthening high off to our northeast and east we will see a very strong pressure gradient. This is going to allow the wind to become strong in our region with the passage of this system. Two main bouts of precipitation will occur. The first one will take place with the system’s warm front, rain for most of the region from this evening to about mid morning Friday, when most of the expected 1 to 2 inches of rain will fall. A few areas may see amounts greater than 2 inches, while under 1 may occur on parts of Cape Cod. The strongest wind gusts are looking like they will take place from about 4 a.m. to about 10 a.m., when gusts of 45 to 65 MPH are possible, strongest being in eastern MA and RI coastal areas and higher elevations. This timing does reduce the chance of wind-driven coastal flooding as the high tide time is later in the day Friday, when we’ll be experiencing a lull in the strongest wind, and then a burst of wind from the southwest as the cold front moves through with a band of rain squalls. Once that goes by, we experience a rapid temperature drop from west to east. Thankfully, the continued wind and rapid drying of the air should help many surfaces dry off before they would have frozen up. But any puddles or areas that manage to remain wet will become icy rather rapidly during Friday evening. In addition, snow showers in the area behind the cold front may cause a small accumulation in some areas, which can add to the slippery conditions. One of our more dramatic temperature drops we’ve had in a while will take place – a matter of up to 40 degrees or so in just a couple hour’s time. This sets us up for a blustery and cold Christmas Eve and Christmas Day with a strong westerly air flow behind the departing storm which will be moving through eastern Canada. Saturday’s wind will be strongest, and Sunday’s will diminish slightly. Both days may see a few isolated snow showers surviving a trip from the Great Lakes, and on Saturday, the South Coast may pick up a bit of accumulating ocean-effect snow with a southwesterly wind – not too often a direction associated with ocean-effect snow in this area. By Monday, high pressure will bring cold but more tranquil weather to the region.

TODAY: Early limited sun, then cloudy. Highs 38-45. Wind E up to 10 MPH.

TONIGHT: Overcast. Rain arrives southwest to northeast, heavy at times overnight. Slight chance of thunderstorms after 3 a.m. Temperatures rising to 45-52. Wind E increasing to 10-20 MPH evening, SE 15-30 MPH with gusts over 40 MPH overnight, strongest coast.

FRIDAY: Mostly cloudy. Rain with embedded heavier rain showers and a slight chance of thunderstorms through mid morning, a lull, then a rain squall likely from southwest to northeast during the first half of the afternoon. Minor coastal flooding possible. Highs 53-60 occurring morning-midday, with a rapid drop beginning mid afternoon from southwest to northeast. Wind SE 20-35 MPH with gusts 45-65 MPH, strongest in higher elevations and coastal areas of eastern MA and RI, through mid morning, then diminishing slightly, then shifting to SW 15-35 MPH with gusts over 40 MPH.

FRIDAY NIGHT: Variably cloudy evening with snow showers possible – minor accumulation may occur. Rapid icing over of any wet surfaces. Partly cloudy to clear overnight. Lows 12-19. Wind SW 15-30 MPH with higher gusts.

SATURDAY: Sun/cloud mix. Isolated to scattered snow showers possible, especially South Coast. Highs 28-35. Wind SW 15-25 MPH, higher gusts.

SATURDAY NIGHT (CHRISTMAS EVE): Partly cloudy. Isolated snow showers. Lows 12-19. Wind WSW 10-20 MPH.

SUNDAY (CHRISTMAS): Partly cloudy. Isolated snow showers. Highs 27-34. Wind W 5-15 MPH, higher gusts.

SUNDAY NIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 28-35. Wind W up to 10 MPH.

DAYS 6-10 (DECEMBER 27-31)

Current indications are for a quiet home stretch of 2022 with high pressure in control, starting with chilly weather followed by a moderating trend as high pressure shifts more to the south and east of New England with time.

DAYS 11-15 (JANUARY 1-5)

As 2023 arrives, watching the first couple days for a possible storm system bringing a rain threat with mild weather, then a return to dry weather and a more seasonable chill thereafter.

DAYS 1-5 (DECEMBER 21-25)

The winter solstice occurs at 4:48 p.m. today. High pressure area then moves over our area for a cold, bright and tranquil day. You will notice some high cloudiness at times today well in advance of our next storm system. These clouds thicken up tonight into Thursday. Developing and rapidly deepening the low pressure will move through the Great Lakes Thursday night and Friday bringing us a windy rain event which may start with some snowflakes in the higher elevations well to the Northwest of Boston and end as a mix or snow as a strong cold front sweeps through on Friday evening. Strong to damaging winds accompany this event. We will see some minor to moderate coastal flooding at the time of high tide due to astronomically high tides combined with strong wind. Areas that do not dry off with wind Friday night can experience a flash freeze with a rapidly dropping temperature. Cold and mainly dry weather with blustery conditions can be expected for the weekend – Christmas Eve and Christmas Day. We’ll have to watch for some snow showers that may survive their trip from the Great Lakes, and also a period of somewhat rare ocean-effect snow bands from southwest winds may occur along and near the South Coast Saturday. Dry weather and less wind is expected Monday with high pressure in control.

TODAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

TONIGHT: Partly cloudy. Lows 22-29. Wind calm.

THURSDAY: Mostly cloudy. Highs 38-45. Wind E up to 10 MPH.

THURSDAY NIGHT: Cloudy. Rain arrives, may begin as snow/mix some inland locations. Lows 32-39 evening, likely warming overnight. Wind up to 10 MPH early, shifting to SE 5-15 MPH inland and 15-25 MPH coastal areas with higher gusts overnight.

FRIDAY: Mostly cloudy. Rain showers likely, some possibly heavy. Highs 55-62. Wind SE to S 15-35 MPH with gusts 40-55 MPH, possibly even higher in some coastal areas and higher elevations.

FRIDAY NIGHT: Mostly cloudy early evening with rain showers ending, possibly as snow showers with a brief coating of snow possible. Watch for rapid ice-over of wet surfaces by late evening / overnight. Partly cloudy to mostly clear overnight. Lows 20-27. Wind SW 15-35 MPH, higher gusts.

SATURDAY: Partly cloudy. Isolated to scattered snow showers possible, especially South Coast. Highs 28-35. Wind SW 15-25 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Isolated snow showers. Lows 12-19. Wind WSW 10-20 MPH.

SUNDAY (CHRISTMAS): Partly cloudy. Isolated snow showers. Highs 27-34. Wind W 5-15 MPH, higher gusts.

DAYS 6-10 (DECEMBER 26-30)

Generally dry and cold weather is expected much of the period. Watching for one wave of low pressure that may bring some snow or mix around December 27.

DAYS 11-15 (DECEMBER 31 – JANUARY 4)

Low confidence forecast. Indications of moderating temperatures early to mid period, a precipitation threat around the New Year, then a dry/colder finish.

DAYS 1-5 (DECEMBER 20-24)

A brisk northwesterly air flow continues today between low pressure in eastern Canada and high pressure approaching via the Great Lakes with a bright but chilly and breezy day for us. The high pressure area then moves over our area for a cold, bright and tranquil Wednesday for Winter Solstice (which occurs at 4:48 p.m.). But things change in a big way heading through Thursday and Friday as a rapidly deepening low pressure area moves through the Great Lakes, and its contrast with high pressure moving east of our region will create strong to powerful southeasterly to southerly winds here and a couple periods of rain, including some potential heavy rainfall. Thursday night to Friday evening. It will not likely rain the entire time though as there may very well be a couple dry periods in between bands. The final band will be on a strong cold front and may arrive quickly enough so that the rainfall ends as mixed precipitation or even snow, enough for a brief coating on some surfaces. More threatening is that areas that do not dry out from the wind can freeze over quickly later Friday night as the temperature drops rapidly, so keep that in mind if traveling later at night and early Saturday. Cold and mainly dry weather with blustery conditions can be expected for the weekend – Christmas Eve and Christmas Day. We’ll have to watch for some snow showers that may survive their trip from the Great Lakes, and also a period of somewhat rare ocean-effect snow bands from southwest winds may occur along and near the South Coast Saturday.

TODAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 16-23. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind calm.

THURSDAY: Mostly cloudy. Highs 38-45. Wind E up to 10 MPH.

THURSDAY NIGHT: Cloudy. Rain arrives, may begin as snow/mix some inland locations. Lows 32-39 evening, likely warming overnight. Wind up to 10 MPH early, shifting to SE 5-15 MPH inland and 15-25 MPH coastal areas with higher gusts overnight.

FRIDAY: Mostly cloudy. Rain showers likely, some possibly heavy. Highs 55-62. Wind SE to S 15-35 MPH with gusts 40-55 MPH, possibly even higher in some coastal areas and higher elevations.

FRIDAY NIGHT: Mostly cloudy early evening with rain showers ending, possibly as snow showers with a brief coating of snow possible. Watch for rapid ice-over of wet surfaces by late evening / overnight. Partly cloudy to mostly clear overnight. Lows 20-27. Wind SW 15-35 MPH, higher gusts.

SATURDAY: Partly cloudy. Isolated to scattered snow showers possible, especially South Coast. Highs 28-35. Wind SW 15-25 MPH, higher gusts.

DAYS 6-10 (DECEMBER 25-29)

Breezy and cold Christmas Day with isolated snow showers possible otherwise dry weather. Generally dry and cold weather is expected through the middle portion of next week though keep an eye out for one possible disturbance with some snow showers.

DAYS 11-15 (DECEMBER 30 – JANUARY 3)

Low confidence forecast. Indications of moderating temperatures early to mid period, a precipitation threat around the New Year, then a dry/colder finish.

DAYS 1-5 (DECEMBER 19-23)

A northwesterly air flow dominates our weather today and Tuesday between eastern Canadian low pressure and central Canadian high pressure, bringing dry, breezy, and chilly weather. That high will sink southeastward and move across the region Wednesday, also a dry and chilly but more tranquil day as we lose the gusty breeze. Things change as we head later into the week. A complex low pressure system will be set to impact our region. First some lead energy develops an initial rain area along the Mid Atlantic Coast which then heads northward, reaching our region in the evening, but may start as snow/mix with some chilly air trapped in the area. While this is going on another low will take shape and rapidly deepen in the Midwest while heading for the Great Lakes. There are still some details about this system that remain unknown, such as how far west it tracks, which holds a key to how quickly the lingering cool air can be pushed out of our region, as it sometimes happens above us but not at the surface nearly as quickly, if at all, in this set-up. For now, I lean toward a warm front making it through, and Friday being a breezy and very mild day with rain showers, culminating in a rain squall line as a cold front sweeps across the region ahead of the rapidly deepening storm in the Great Lakes Friday evening. As for more precise timing, we’ll have to nail that down later in the week. The system will likely produce some significant and possibly damaging wind gusts.

MONDAY: Partly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 16-23. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind calm.

THURSDAY: Mostly cloudy. Highs 38-45. Wind E up to 10 MPH.

THURSDAY NIGHT: Cloudy. Rain arrives, may begin as snow/mix some inland locations. Lows 32-39 evening, likely warming overnight. Wind up to 10 MPH early, shifting to SE 5-15 MPH inland and 15-25 MPH coastal areas with higher gusts overnight.

FRIDAY: Mostly cloudy. Rain showers likely. Highs 55-62. Wind SE 15-25 MPH with higher gusts.

DAYS 6-10 (DECEMBER 24-28)

A blustery, cold Christmas Eve & Christmas Day can be expected in the wake of powerful low pressure moving through eastern Canada. A few snow showers may survive a trip from the Great Lakes into our region. Generally dry and cold weather is expected early to middle portion of next week but watching around December 27 for a potential snow/mix/rain threat.

DAYS 11-15 (DECEMBER 29 – JANUARY 2)

Not a high confidence forecast, but after a chilly start it may moderate with a rain or snow threat sometime around the beginning of 2023.

The weekly…

DAYS 1-5 (DECEMBER 18-22)

Upper level low pressure crosses the region today with a gusty breeze, some clouds, and maybe a few passing snow flurries. Monday and Tuesday will be breezy and chilly days with an air flow out of Canada between low pressure in eastern Canada and high pressure approaching via the Great Lakes. This high will move over our region with dry, cold, tranquil weather on Wednesday. We’ve been watching a window of time where we are vulnerable to stormy weather on December 22 and 23, and that’s still there. While not set in stone, it’s starting to look like we’ll be looking at a rapidly strengthening low pressure moving into the Great Lakes by later Thursday, and during that day here we’ll see clouds thicken up, along with milder air arriving, so that we are probably looking at a rain event beginning by that night. Still will have to fine-tune some details about this system is we get closer to it.

TODAY: Variably cloudy. A passing snow flurry possible especially this afternoon. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 16-23. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind calm.

THURSDAY: Mostly cloudy. Highs 38-45. Wind E up to 10 MPH.

DAYS 6-10 (DECEMBER 23-27)

Stormy weather on December 23 should be in the form of rain and rain showers with gusty wind and mild air as strong low pressure passes northwest of the region. Christmas Eve and Christmas Day look blustery, cold, and mainly dry, perhaps a passing snow shower at times, behind this system as it exits through eastern Canada. Watching for a quick moving disturbance from Canada with a snow shower or light snow threat by the end of the period with continued chilly late December conditions.

DAYS 11-15 (DECEMBER 28 – JANUARY 1)

Starting chilly with mostly dry weather, maybe a brief light snow threat from a passing disturbance, then a few hints of a quick moderation in temperature toward the New Year’s Eve / New Year’s Day time frame.

DAYS 1-5 (DECEMBER 17-21)

The slow process of saying goodbye to our current bout of unsettled weather is underway. This storm was noted for producing plenty of rain and wind for the coastal plain, and a significant snow for the highest elevations of the WHW forecast area (southwestern NH and far north central MA). As we have expected, the colder air is filtering back eastward into the coastal plain where rain showers have becoming mixed with or changed to snow showers. We’ve lost the steadiest and heavier precipitation though, so just minor dustings / coatings of snow will occur with some of these snow showers. The general trend will be for drying, but we’ll hang onto the cloud cover through the day, seeing that break up more tonight. Sunday looks like a chilly but mainly dry day – only the chance of a few passing light snow showers in response to upper level low pressure moving through the region. Then, as we come down the home stretch of autumn toward the winter solstice, which occurs Wednesday at 4:48 p.m., we will be in a chilly but mainly dry weather pattern with high pressure providing plenty of low-angle sun Monday and Tuesday. Wednesday may some intervals of clouds and perhaps a later-day or evening snow shower associated with a passing trough, but this will be a very minor system with no significant impact.

TODAY: Mainly cloudy – rain and snow showers at times until midday favoring southeastern NH, eastern MA, and RI. Highs 35-42. Wind W 10-20 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 22-29. Wind NW 10-20 MPH.

SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 16-23. Wind W 5-15 MPH.

WEDNESDAY: Partly cloudy. A late day snow shower possible. Highs 33-40. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 22-26)

Likely impact by a storm system later December 22 into December 23 but highly uncertain of storm track and resultant weather here – stay tuned. Generally dry and cold pattern thereafter but may be a minor snow/mix producer right around Christmas Day.

DAYS 11-15 (DECEMBER 27-31)

Still a low confidence forecast but overall pattern looks chilly with one or two precipitation chances but overall on the dry side heading down the home stretch of 2022.

DAYS 1-5 (DECEMBER 16-20)

A rain event for most – except some higher elevation snow well inland (southwestern NH to parts of north central MA) today. This occurs as a redeveloped low wraps up just south of our region then moves to just east of the region by Saturday, at which time colder air moves back in and rain ends as snow showers for some areas. Upper level low pressure still has to cross the region Sunday with a few more snow showers possible, then high pressure noses back in for cold and dry weather early next week.

TODAY: Cloudy with rain likely, except snow with additional accumulation possible in highest elevations of north central MA through southwestern NH. Areas of fog. Highs 38-45 north and west of Boston, 45-52 Boston southeastward, mildest over Cape Cod and Islands. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coast, may shift to S late day over Cape Cod and Islands.

TONIGHT: Overcast with rain likely through the evening hours, tapering off to rain showers overnight. Lows 35-42. Wind briefly variable around Cape Cod otherwise E to NE 10-20 MPH with higher gusts evening, shifting to W overnight.

SATURDAY: Mostly cloudy. Rain showers turning to snow showers west to east before tapering off. Some minor accumulation of snow is possible in portions of southern NH and northern MA. Highs 38-45 early, then turning colder. Wind W to NW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 10-20 MPH.

SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

DAYS 6-10 (DECEMBER 21-25)

Still watching the window of December 22-23 for a potential storm, and with medium range guidance showing a large spread of outcomes, there is a lot of uncertainty and it remains impossible to attempt any detailing whatsoever, other than to say the signal is there for an East Coast storm system pre-Christmas, with mostly dry and cold weather both before and after it.

DAYS 11-15 (DECEMBER 26-30)

Overall pattern looks cold with one or two precipitation chances, but with uncertainties before this, the confidence becomes even lower for this period.
