DAYS 1-5 (DECEMBER 30 – JANUARY 3)

Upper level low pressure and a surface cold front swing through from northwest to southeast today, maintaining unsettled weather for several hours. We’ll start to see improvement at the end of the day as the front pulls through and drier air arrives. Behind this front it turns more seasonably chilly for the end of the weekend and the final day of 2023 on Sunday with dry weather. A trough passing by on Monday may be responsible for a rain or snow shower in a few locations as we greet 2024. A dry, chilly westerly air flow is expected for Tuesday and Wednesday, but later Wednesday another weak cold frontal boundary approaching may cause a snow flurry.

TODAY: Mostly cloudy through midday with a chance of rain showers. Decreasing clouds late-day from northwest to southeast. Highs 38-45. Wind W up to 10 MPH, shifting to NW 5-15 MPH by late-day.

TONIGHT: Partly cloudy. Lows 23-30. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 36-43. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 25-32. Wind W up to 10 MPH.

MONDAY: Partly sunny. A passing snow flurry possible. Highs 33-40. Wind W 5-15 MPH.

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

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

TUESDAY NIGHT: Partly cloudy. Lows 22-29. Wind W 5-15 MPH.

WEDNESDAY: Partly sunny. A passing snow flurry possible. Highs 36-41. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 4-8)

Disturbance passes by early period with minor precipitation threat but more organized storminess gets going offshore and moves away. Will watch for a southern jet stream storm system near or south of the region later in the period. Polar jet stream remains in Canada – temps run on the mild side of normal.

DAYS 11-15 (JANUARY 9-13)

We’ll feel the effects of a slow pattern transition with a bit more chill. A dry pattern early to mid period. A storm threat may present itself late period.

DAYS 1-5 (DECEMBER 29 – JANUARY 2)

Low pressure brings additional damp weather today. An upper trough and frontal system pass through Saturday with a little bit of lingering unsettled weather. The trend is drier and a little colder to end 2023 and begin 2024, but a quick shower of rain and/or snow may accompany the passage of a trough on New Year’s Day.

TODAY: Cloudy. Periods of light rain possible. Areas of fog. Highs 41-48. Wind N up to 10 MPH.

TONIGHT: Mostly cloudy. Lows 33-40. Wind W up to 10 MPH.

SATURDAY: Mostly cloudy to partly sunny. Chance of rain and/or snow showers. Highs 37-44. Wind W-NW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 23-30. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 36-43. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 25-32. Wind W up to 10 MPH.

MONDAY: Partly sunny. A passing snow flurry possible. Highs 33-40. Wind W 5-15 MPH.

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

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

DAYS 6-10 (JANUARY 3-7)

Dry and seasonably chilly weather with high pressure in control during the middle of next week before an unsettled weather threat later in the period.

DAYS 11-15 (JANUARY 8-12)

This period features mainly dry weather and an unsteady but general trend toward colder weather.

DAYS 1-5 (DECEMBER 28 – JANUARY 1)

A series of low pressure areas results in a spell of unsettled weather until Saturday. The first one moving by just to our southeast today gives us most of our rainfall, especially the first half of the day. A follow up low can produce periods of additional rain through Friday. An upper level low and surface cold front have to swing through on Saturday with a rain and snow shower threat. The balance of the holiday weekend will feature more seasonably chilly weather as we say bye to 2023 Sunday and hi to 2024 Monday. Mainly dry weather is expected, but I can’t rule out a passing snow flurry with a weak disturbance moving through the region on Monday.

TODAY: Overcast with widespread rain and areas of fog through midday. Mostly cloudy with spotty light rain and drizzle during the rest of the day. Highs 42-49. Wind NE 5-15 MPH.

TONIGHT: Mostly cloudy. Areas of fog and drizzle. Lows 38-45. Wind N up to 10 MPH.

FRIDAY: Cloudy. Periods of light rain possible. Areas of fog. Highs 41-48. Wind N up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Lows 33-40. Wind W up to 10 MPH.

SATURDAY: Mostly cloudy to partly sunny. Chance of rain and/or snow showers. Highs 37-44. Wind W-NW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 23-30. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 36-43. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 25-32. Wind W up to 10 MPH.

MONDAY: Partly sunny. A passing snow flurry possible. Highs 33-40. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 2-6)

Dry and seasonably chilly weather with high pressure in control through the middle of next week before an unsettled weather threat looms later in the period.

DAYS 11-15 (JANUARY 7-11)

Unsettled weather threat comes early period with a rain/snow chance. Drier weather follows. Temperatures near normal.

DAYS 1-5 (DECEMBER 27-31)

Unsettled weather will be dominant until the start of the weekend as a series of low pressure areas impact the region. This morning, while not as widespread as yesterday, there will be some areas of visibility-reducing fog, and today the sun is not as likely to break out once the fog burns off, as more cloud cover will be prevalent. Low pressure emerging off the Mid Atlantic Coast by tonight will move just southeast of New England during Thursday, producing a spell of rain for our region. This will taper off for a time, but additional periods of rain can still occur through Friday with a follow-up low, this one weaker, moving by the region. Finally, upper level low pressure swings through during Saturday with some lingering rain and snow showers as slightly colder air arrives. Finally, high pressure moves in with fair, seasonably chilly weather for the final day of 2023 on Sunday.

TODAY: Cloudy. Areas of fog this morning. Highs 42-49. Wind SW to variable under 10 MPH.

TONIGHT: Cloudy. Rain arrives. Areas of fog. Lows 38-45. Wind variable to NE up to 10 MPH.

THURSDAY: Cloudy. Rain likely. Areas of fog. Highs 42-49. Wind NE 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain tapers off. Areas of fog and drizzle. Lows 38-45. Wind NE up to 10 MPH.

FRIDAY: Cloudy. Periods of light rain possible. Areas of fog. Highs 41-48. Wind NE-N up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of rain and/or snow showers. Lows 32-39. Wind N 5-15 MPH.

SATURDAY: Mostly cloudy to partly sunny. Chance of rain and/or snow showers. Highs 37-44. Wind N-NW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 23-30. Wind NW 5-15 MPH.

SUNDAY: Partly sunny. Highs 36-43. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 1-5)

Drier and more seasonably chilly pattern to start 2024.

DAYS 11-15 (JANUARY 6-10)

Unsettled weather threat comes early to mid period with rain/snow chances. Drier weather follows. Temperatures near normal.

DAYS 1-5 (DECEMBER 26-30)

Where’s Rudolph when you really need him? A very foggy start to the day after Christmas across the region as calm wind is met with matching temperature and dew point essentially across the entire WHW forecast area. If you have plans to travel on the roads, use caution from early through mid morning until the fog finally thins out and dissipates. This will take place as a southwesterly breeze develops and warms the temperature above dew point levels while also mixing the air up to clear the fog. Some fog patches may re-develop tonight though as we have very light wind. Wednesday, a southeast breeze will repeat the process that today’s southwest breeze does. The southeast breeze Wednesday will be ahead of low pressure that will move up from the Mid Atlantic and bring our region a slug of rain Wednesday afternoon and night into Thursday morning, before tapering off as the low moves away. But we’ll remain unsettled into late week as a follow-up low moves just south of the region Friday and still upper level energy has to pull through the region on Saturday. Additional precipitation Friday would be in the form of rain, but as we get to Saturday, colder air filtering in would mean some areas would flip to snow showers before it dried out.

TODAY: Dense fog into mid morning eventually thins out and dissipates. Mostly cloudy. Highs 46-53. Wind calm then SW up to 10 MPH.

TONIGHT: Mostly cloudy. Areas of fog. Lows 36-43. Wind S under 10 MPH.

WEDNESDAY: Cloudy. Rain arriving. Highs 43-50. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 38-45. Wind E 5-15 MPH.

THURSDAY: Cloudy start – rain tapers off. Mostly cloudy with a chance of rain showers in the afternoon. Highs 45-52. Wind NE-N 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain possible. Patchy fog. Lows 38-45. Wind NE up to 10 MPH.

FRIDAY: Mostly cloudy. Rain possible. Highs 40-47. Wind NE up to 15 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of rain and/or snow showers. Lows 32-39. Wind N 5-15 MPH.

SATURDAY: Mostly cloudy to partly sunny. Chance of snow showers through midday. Highs 35-42. Wind N-NW 5-15 MPH.

DAYS 6-10 (DECEMBER 31 – JANUARY 4)

Dry end to 2023. Watch for potential unsettled weather from low pressure in the region around January 2. Fair weather returns later in the period. Temperatures near normal.

DAYS 11-15 (JANUARY 5-9)

Another storm threat possible around mid period with rain/snow chances. Temperatures near normal.

DAYS 1-5 (DECEMBER 25-29)

Merry Christmas! A quiet holiday for those celebrating today with a light wind, lots of clouds, and areas of fog, especially to start the day. But it will be a precipitation-free day with generally fine conditions for local / regional travel. The quiet weather will continue through Tuesday. Then low pressure winding up through the Midwest will redevelop in the Mid Atlantic and move off our coast later Wednesday to early Thursday. Here, the air will be mild enough for this to be a rain event. This one will not be nearly as potent as the recent one. As this low moves away, upper level low pressure in the region will keep it somewhat unsettled into late week as well, but with a bit of a cool-down, so we may see snow showers in additional rain showers, depending on timing and location.

TODAY (CHRISTMAS DAY): Areas of fog this morning. Mostly cloudy. Highs 45-52. Wind variable under 10 MPH.

TONIGHT: Mostly cloudy. Areas of fog. Lows 33-40. Wind variable under 10 MPH.

TUESDAY: Lots of clouds / limited sun. Highs 46-53. Wind variable up to 10 MPH becoming S.

TUESDAY NIGHT: Mostly cloudy. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Cloudy. Rain arriving. Highs 43-50. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 38-45. Wind E 5-15 MPH.

THURSDAY: Cloudy start – rain tapers off. Lots of clouds, limited sun, and a passing rain shower possible afternoon. Highs 45-52. Wind NE-N 5-15 MPH.

THURSDAY NIGHT: Lots of clouds. A rain or snow shower possible. Lows 33-40. Wind N 5-15 MPH.

FRIDAY: Lots of clouds. A rain or snow shower possible. Highs 35-42. Wind N 5-15 MPH.

DAYS 6-10 (DECEMBER 30 – JANUARY 3)

Upper level low pressure hangs around for the potential of a few rain and snow showers December 30. High pressure brings dry weather December 31. Watching for the approach of low pressure and a return to unsettled weather in the first couple days of the new year but there continues to be indications this system may be shunted to the south of the region with mostly dry weather here. Temperatures not far from normal.

DAYS 11-15 (JANUARY 4-8)

Dry start. Storm threat may materialize mid to late period with rain/snow chances.

DAYS 1-5 (DECEMBER 24-28)

Quiet, mainly cloudy, and mild is the theme for Christmas Eve & Christmas Day. A weak disturbance moving slowly through the region will be responsible for the abundant cloudiness along with some isolated patches of rain. If it rains where you are, it won’t last long, but if it happens early today west of I-95, watch for some black ice on untreated surfaces as temperatures sit around freezing to start out the day. Any icing issues will be short lived though as the temperature goes up enough to end it. Some lower level moisture especially in coastal areas can result in low clouds, patchy fog, and a couple spots of drizzle through early Christmas morning. If Rudolph needs to use his nose to help Santa tonight, it will be due to fog patches, not snowy weather. None of that around this time for the holiday! Looking ahead, a milder southerly air flow kicks in Tuesday as a weak ridge of high pressure slides over the region early then offshore. Clouds likely stay somewhat dominant on Tuesday though. When we get to midweek, we’ll be dealing with a larger scale low pressure system. Initially this storm matures and occludes out in the Midwest, and its energy stretches out and weakens as it moves east and northeast, but a redevelopment of the low will likely bring a slug of rain with mild air in place during Wednesday. By Thursday, this is moving beyond our region and we turn slightly colder, with a few rain/snow showers possible as upper level low pressure drifts over the region.

TODAY: Mostly cloudy. Isolated rain showers. Patchy coastal drizzle and fog. Highs 39-46. Wind variable up to 10 MPH.

TONIGHT (CHRISTMAS EVE): Mostly cloudy. Isolated rain showers. Patchy coastal drizzle and fog. Lows 33-40. Wind variable up to 10 MPH.

MONDAY (CHRISTMAS DAY): Mostly cloudy to partly sunny. Highs 43-50. Wind variable up to 10 MPH.

MONDAY NIGHT: Mostly cloudy. Lows 25-32. Wind N up to 10 MPH.

TUESDAY: Lots of clouds / limited sun. Highs 45-52. Wind variable up to 10 MPH becoming S 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Cloudy. Rain arriving. Highs 43-50. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 38-45. Wind SE 5-15 MPH.

THURSDAY: Partly sunny. A rain or snow shower possible. Temperatures steady 38-45 to start but may fall slightly during the afternoon. Wind SW 5-15 MPH.

DAYS 6-10 (DECEMBER 29 – JANUARY 2)

Upper level low pressure may produce a few rain/snow showers December 29. Fair weather with high pressure in control December 30-31. Watching for the approach of low pressure and a return to unsettled weather in the first couple days of the new year but some indications are for this system to be kept to the south with more dry weather here. Temperatures above to near normal with a general cooling trend.

DAYS 11-15 (JANUARY 3-7)

General trend is for a more seasonably chilly pattern but with storminess kept to the south, at least until late in the period when a precipitation threat is possible.

DAYS 1-5 (DECEMBER 23-27)

Quiet weather for the next few days, including Christmas Eve and Christmas Day, but a warm front and disturbance moving slowly through the region will make C.E. & C.D. a little more cloudy as we turn milder. A weak cold front will come by the region on Tuesday with little fanfare. However, we are in El Nino, and the next storm system born of the subtropical jet stream will be here by the middle of next week, but again it looks like a rain event as the cold air will be trapped well to the north in Canada with the polar jet stream.

TODAY: Sun gives way to clouds. Highs 35-42. Wind variable up to 10 MPH.

TONIGHT: Mostly cloudy. A few snow showers possible. Lows 25-32. Wind variable under 10 MPH.

SUNDAY: Cloudy with patchy drizzle and a possible rain shower morning. Mostly cloudy to partly sunny afternoon. Highs 39-46. Wind variable under 10 MPH becoming SW.

TUESDAY NIGHT: Partly cloudy. Lows 32-39. Wind SE under 10 MPH.

WEDNESDAY: Cloudy. Rain arriving. Highs 43-50. Wind SE 5-15 MPH.

DAYS 6-10 (DECEMBER 28 – JANUARY 1)

Upper level low pressure may produce a few rain/snow showers December 28-29. Fair weather with high pressure in control December 30-31. Watching for the approach of low pressure and a return to unsettled weather as early as the first day of 2024. Temperatures above normal.

DAYS 11-15 (JANUARY 2-6)

Unsettled weather potential very early and again later in the period. Temperatures above to near normal.

DAYS 1-5 (DECEMBER 22-26)

We have a quiet pattern in place that will be with us right through Christmas Day and slightly beyond, which may not be very helpful for creating a white Christmas, but will be great news for travel up to and through the holiday. A chilly high pressure controls the weather today. Moderation gets underway Saturday. A warm front will cross the region Saturday night and early Sunday and may produce a few patches of very light rain and snow in the region, then fair, milder weather is ours for the balance of Christmas Eve to Boxing Day aka the day after Christmas. A weak cold front will slide into the region later Tuesday but without any issues.

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

TONIGHT: Partly cloudy. Lows 15-22. Wind N up to 10 MPH.

MONDAY (CHRISTMAS DAY): Mostly sunny. Highs 43-50. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 25-32. Wind SW up to 10 MPH.

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

DAYS 6-10 (DECEMBER 27-31)

Low pressure brings a rain chance December 27 with milder air in place and an inland low track. Upper level low pressure may bring a few rain/snow showers December 28 and a few flurries December 29 as colder air returns. Fair weather with high pressure for December 30-31 to wrap up 2023 in a quiet note.

DAYS 11-15 (JANUARY 1-5)

Watch for a disturbance with some precipitation around the first couple days of 2024, otherwise a fairly quiet pattern to start the new year with no major temperature extremes.

DAYS 1-5 (DECEMBER 21-25)

A continued northerly air flow between high pressure to the west and low pressure off the coast will bring fair and seasonably chilly weather through Friday as we end Autumn and welcome Winter – the solstice is tonight at 10:27 p.m.. A weak disturbance will bring more clouds and perhaps a touch of very light precipitation late Saturday to early Sunday, before high pressure takes over for a dry and slightly milder Christmas Day. This weather pattern remains very favorable for travel and errands leading up to and through the holiday.

TODAY: Mostly sunny. Highs 36-43. Wind N-NE 5-15 MPH.

TONIGHT: Partly cloudy. Lows 21-28. Wind N-NE 5-15 MPH.

SUNDAY NIGHT (CHRISTMAS EVE): Mostly clear. Lows 22-29. Wind SW up to 10 MPH.

MONDAY (CHRISTMAS DAY): Mostly sunny. Highs 43-50. Wind SW 5-15 MPH.

DAYS 6-10 (DECEMBER 26-30)

Low pressure approaches December 26 with clouds returning, then a good rain chance December 27 with a storm system passing through the Northeast, low center to our west and mild air in place as it looks at this point. Upper level low pressure may cause a few rain/snow showers with a slight cool-down later in the period, but no major cold indicated.

DAYS 11-15 (DECEMBER 31 – JANUARY 4)

Dry weather to end 2023. Watching for a low pressure system and precipitation threat in the January 1-2 time frame, with fair, colder weather after that.

DAYS 1-5 (DECEMBER 20-24)

A northerly air flow between high pressure to the west and low pressure off the coast will bring fair and seasonably chilly weather through Friday. A weak disturbance will bring more clouds and perhaps a touch of very light precipitation Saturday, before high pressure takes over for a dry and slightly milder Christmas Eve. This pattern is very favorable for pre-holiday travel and errands.

TODAY: Mostly sunny. Highs 37-44. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 21-28. Wind N 5-15 MPH.

SUNDAY (CHRISTMAS EVE): Mostly sunny. Highs 38-45. Wind SW up to 10 MPH.

DAYS 6-10 (DECEMBER 25-29)

A fair, mild Christmas Day with high pressure in control. Low pressure approaches December 26 with clouds returning, then a good rain chance December 27 with a storm system passing through the Northeast, low center to our west and mild air in place as it looks at this point. Upper level low pressure may cause a few rain/snow showers with a slight cool-down later in the period, but no major cold indicated.

DAYS 11-15 (DECEMBER 30 – JANUARY 3)

Dry weather for the last couple days of 2023. Watching for a low pressure system and precipitation threat in the January 1-2 time frame, with fair, colder weather after that.

DAYS 1-5 (DECEMBER 19-23)

Upper level low pressure may produce a couple rain and snow showers today as it swings through the region from west to east. A northerly air flow between high pressure to the west and low pressure off the coast will bring fair and seasonably chilly weather Wednesday through Friday. Another disturbance moves into the region on Saturday and may produce some insignificant light snow, except snow or rain near the South Coast.

TODAY: Variably cloudy. Chance of rain showers except mix/snow showers possible in some higher elevations. Highs 38-45. Wind W 5-15 MPH.

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

DAYS 6-10 (DECEMBER 24-28)

Christmas Eve / Christmas Day feature fair, milder weather with high pressure in control. Watch for a frontal boundary and a rain/snow shower chance December 26. Potential widespread precipitation event later in the period from low pressure associated with the subtropical jet stream.

DAYS 11-15 (DECEMBER 29 – JANUARY 2)

Trend back to mainly dry weather at least through mid period. No major cold.

DAYS 1-5 (DECEMBER 18-22)

A stormy Monday starts this week before Christmas. A well-advertised storm system will move up from the south, with the center of low pressure basically traveling up the Connecticut River Valley during this afternoon. Steadiest rain this morning becomes more showery this afternoon with a general 1 to 3 inch rainfall for the region. Strongest wind gusts from the southeast and south will be around through early afternoon before the wind shifts to the southwest and, while still strong and gusty, the top gusts should be behind us. Coastal flooding will be minor to moderate around the high tide time at midday, most notable along the South Coast. As the storm moves away, we stay breezy into tonight, but dry weather returns. Overnight temperatures should stay above freezing so I’m not concerned about any freezing of leftover puddles and surfaces that don’t dry out quickly. Tuesday, we’ll have upper level low pressure crossing the region, with cooler weather and a chance of a few rain and snow showers, but no big deal. The weather Wednesday through Friday will be governed by high pressure with dry and seasonably chilly weather. A blocking pattern will result in low pressure sitting offshore to our east, but indications are that other than the wind turning more northeast Thursday and/or Friday, and some coastal cloud potential, that the system will not have any significant impact on our weather.

TODAY: Overcast through midday with rain, heavy at times, and a slight chance of thunderstorms. Mostly cloudy with additional rain showers during the afternoon but breaks of sun are also possible. Highs 57-64. Wind SE 15-35 MPH with gusts above 40 MPH inland and above 50 MPH coastal areas, shifting to S.

MONDAY NIGHT: Variably cloudy. Lows 34-41. Wind SW 15-25 MPH, higher gusts.

TUESDAY: Variably cloudy. Chance of rain showers except mix/snow showers possible in some higher elevations. Highs 38-45. Wind W 10-20 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 22-29. Wind WNW 10-20 MPH.

WEDNESDAY: Partly cloudy. Highs 37-44. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 21-28. Wind N 5-15 MPH.

THURSDAY: Mostly sunny to partly cloudy. Highs 36-43. Wind N-NE 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 21-28. Wind N-NE 5-15 MPH.

FRIDAY: Partly sunny. Highs 35-42. Wind N-NE 5-15 MPH.

DAYS 6-10 (DECEMBER 23-27)

Blocking breaks down and a more zonal flow takes over the pattern. Disturbance may bring a few rain and snow showers on December 23. High pressure brings fair, milder weather for Christmas Eve / Christmas Day. Watching for a more significant precipitation event, probably rain, later in the period as low pressure approaches from the southwest.

DAYS 11-15 (DECEMBER 28 – JANUARY 1)

Storm system may be nearby early in the period then quieter again. No major cold.

DAYS 1-5 (DECEMBER 17-21)

The last of high pressure keeps us rain-free during the daylight hours today, but any sun you may see this morning is a bonus as the clouds will take over for an overcast sky. A fast-moving low pressure area is set to bring a wind and rain event to our region tonight and Monday. The set-up looks the same as described in yesterday’s blog post. The low center will travel just west of our area – generally up the Hudson Valley – with moderate to strong winds from the southeast eventually shifting to the south then southwest as the low goes by, and a trough extending southward from it swings through. Heaviest rainfall takes place during the first 12 hours of Monday, with a potential dry slot and cloud breaks before the trough swings through with another batch of rain showers. Still cannot rule out thunder but that’s a low probability. The bigger impacts with this system will be wind with gusts above 40 MPH inland and above 50 MPH near the coast, potentially over 60 MPH over Cape Cod, and heavy rainfall of 1 to 3 inches with local flooding in prone areas, low visibility during heaviest rain, and some coastal flooding, especially South Coast, focused around Monday’s high tide time. After this system departs, upper level low pressure keeps it somewhat unsettled Tuesday with lots of clouds and a few rain and snow showers. Midweek will see dry and seasonably chilly weather between high pressure to our west and an evolving offshore low pressure area.

TODAY: Partial sun into mid morning especially I-95 belt eastward, otherwise cloudy. A patch of drizzle or an isolated rain shower possible in the afternoon. Highs 47-54. Wind E 5-15 MPH.

TONIGHT: Cloudy. Rain arrives, may be heavy at times overnight. Temperatures rise to 50-57. Wind SE increasing to 15-35 MPH with higher gusts, especially coast.

MONDAY: Overcast through midday with rain, heavy at times, and a slight chance of thunderstorms. Mostly cloudy with additional rain showers during the afternoon but breaks of sun are also possible. Highs 57-64. Wind SE 15-35 MPH with gusts above 40 MPH inland and above 50 MPH coastal areas, shifting to S.

DAYS 6-10 (DECEMBER 22-26)

A blocking pattern keeps low pressure over the ocean to our east and high pressure just to the west until about Christmas Day. A weak disturbance or two may produce a touch of light precipitation. Will watch the end of the period for things to un-block in the pattern and a new low pressure system approaching from the southwest with a greater threat of precipitation.

DAYS 11-15 (DECEMBER 27-31)

A little more active outlook in this time frame with more west to east flow and the ability of jet stream disturbances to move into the Northeast. Overall pattern still appears mild with no major cold in sight.

DAYS 1-5 (DECEMBER 16-20)

An area of high pressure keeps our weather fair today. A quick-moving, potent low pressure area that originated in the Gulf of Mexico will fly north northeastward as an inside runner storm – one that has an inland track – bringing us a bout of wind and rain Sunday night into Monday. Ahead of it, a moistening east to southeast air flow will send clouds in tonight into Sunday, but other than a patch of drizzle or a couple “in-advance” rain showers, we won’t see much in the way of rainfall until after dark Sunday, with the most solid rain area coming through during the first 10 to 12 hours of Monday. As low pressure tracks west of the WHW forecast area, a dry slot will shut off the main rainfall and we may even see some breaks in the clouds for a while Monday afternoon before a trough of low pressure trailing the main low center swings through with more showery rainfall Monday evening. This system exits overnight and on Tuesday we’re left with upper level low pressure swinging through the region. This will keep it unsettled with a chance of additional rain showers, possibly mixed with snow in higher elevations as colder air starts to move in. By Wednesday, we’ll be in a dry northwesterly flow between evolving low pressure well offshore and high pressure nudging in from the Ohio Valley / Great Lakes.

TODAY: Mostly sunny. Highs 45-52. Wind N 5-15 MPH shifting to E.

TONIGHT: Clouds increase. Lows 32-39. Wind E under 10 MPH.

SUNDAY: Cloudy. A patch of drizzle or an isolated rain shower possible in the afternoon. Highs 47-54. Wind E 5-15 MPH.

SUNDAY NIGHT: Cloudy. Rain arrives, may be heavy at times overnight. Temperatures rise to 50-57. Wind SE increasing to 15-35 MPH with higher gusts, especially coast.

MONDAY: Overcast through midday with rain, heavy at times, and a slight chance of thunderstorms. Mostly cloudy with additional rain showers during the afternoon but breaks of sun are also possible. Highs 57-64. Wind SE 15-35 MPH with gusts above 40 MPH inland and above 50 MPH coastal areas, shifting to SW.

MONDAY NIGHT: Variably cloudy. Passing rain showers possible evening. Lows 37-44. Wind SW-W 15-25 MPH, higher gusts.

TUESDAY: Variably cloudy. Chance of rain showers except mix/snow showers possible in some higher elevations. Highs 38-45. Wind W 15-25 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 22-29. Wind WNW 10-20 MPH.

WEDNESDAY: Partly cloudy. Highs 37-44. Wind NW 5-15 MPH.

DAYS 6-10 (DECEMBER 21-25)

A blocking pattern keeps low pressure over the ocean to our east and high pressure just to the west from the Winter Solstice to Christmas Day. This is generally a dry pattern with the only chance of precipitation limited to a few rain/mix/snow showers from weak disturbance or two moving through.

DAYS 11-15 (DECEMBER 26-30)

A little more active outlook in this time frame with more west to east flow and the ability of jet stream disturbances to move into the Northeast. Overall pattern still appears mild with no major cold in sight.
