DAYS 1-5 (JANUARY 15-19)
A transition out of mild and back to colder takes place today, but after last night’s light rainfall in the area, today’s temperature drop will take place with mostly dry conditions, just a slight chance of a few lingering raindrops first thing this morning, followed by clouds giving way to more sunshine as the wind picks up and the temperature goes down. A secondary frontal boundary passing by tonight can be responsible for a passing snow shower, even a brief snow squall potentially. This sets up a dry, windy, and cold day Friday. During the weekend (3 days as it includes MLK Jr. Day on Monday) we will be impacted by 3 separate weather systems. Saturday, low pressure passing by to our northwest brings a warm front / cold front combination. While there may be some early-day sun especially in eastern areas, look for a couple periods of rain and snow – rain favoring the coastal plain and snow favoring areas further inland where there can be some minor accumulation. I’ll detail this further on the next blog post tomorrow morning. The second system will bring a swath of snow to Cape Cod and the Islands and perhaps back through the I-95 belt for a few hours on Sunday evening as a fast-moving storm system passes well offshore, heading north northeastward. The third system will be a trough and cold front that can bring a snow shower later Monday, which will be a windy and chilly day.
TODAY: Cloudy morning with spotty light rain except light mix / snow in southwestern NH & central MA. Sun and passing clouds this afternoon. Temperatures start out 37-44 west of I-95 and 40-47 I-95 eastward, falling into the 30s during the day. Wind S shifting to W 5-15 MPH, increasing to 10-20 MPH with higher gusts by late in the day.
TONIGHT: Partly cloudy. An evening snow shower or snow squall possible. Lows 15-22. Wind W 10-20 MPH with higher gusts.
FRIDAY: Mostly sunny. Highs 27-34. Wind W 10-20 MPH, gusts around 30 MPH.
FRIDAY NIGHT: Increasing clouds. Lows 20-27 evening followed by a slow rise overnight. Wind SW 5-15 MPH.
SATURDAY: Mostly cloudy. Periodic light rain eventually mixing with and changing to snow coastal plain, mix to snow inland with accumulation of up to 1 inch (2 inches higher elevations central MA and southwestern NH) by late-day. Highs 32-39 inland and 38-45 coast occurring before midday followed by a gradual temperature fall. Wind S 5-15 MPH shifting to N from west to east.
SATURDAY NIGHT: Decreasing clouds. Lows 23-30. Wind N 5-15 MPH.
SUNDAY: Increasing clouds. Highs 33-40. Wind N 5-15 MPH.
SUNDAY NIGHT: Cloudy. A period of snow mainly I-95 belt eastward with best chance of up to a few inches accumulation over Cape Cod. Lows 22-30. Wind N to NE 5-15 MPH, higher gusts along the coast.
MONDAY: Sun / cloud mix. Chance of late-day or evening snow showers. Highs 25-32. Wind shifting to W 10-20 MPH, higher gusts.
DAYS 6-10 (JANUARY 20-24)
Dry and cold weather into the middle of next week followed by a mix/snow chance later in the week, depending on the track of approaching low pressure.
DAYS 11-15 (JANUARY 25-29)
This period of time continues to feature a leaning toward cold weather and a couple of wintry precipitation chances, with it being too far into the future for any details.
