DAYS 1-5 (APRIL 2-6)
A midweek storm will bother us with wind and a variety of precipitation. It’s to be a slow process both in and out. Today clouds thicken up and rain approaches, making it into areas west and south of Boston later in the day, but drying up somewhat as it pushes northeastward through evening. Renewed precipitation arrives overnight and Wednesday, mainly in the form of rain though some sleet/snow can start to mix in over higher elevations to the north and west as we go through the day. Just enough cold air is around so that sleet/snow will be an issue in northern MA and southern NH at times, with the greatest threat of accumulating snow favoring higher elevations of north central MA and southwestern NH Wednesday night into Thursday before precipitation tapers off to rain/snow showers, which will linger through Friday as low pressure will be slow to start pulling away. In fact, this low will still be impacting us into the start of the weekend with lots of clouds and maybe a few lingering rain showers. During the storm, especially Wednesday and early Thursday, expect fairly strong winds along the coast and some threat of coastal flooding as well. One potential surprise factor: Since temperatures in the atmosphere are very marginal, slightly heavier precipitation or a slightly further southeast low pressure track can pull the frozen precipitation area further east and south, so that will be something to monitor closely.
TODAY: Partial sun early, then cloudy. Later-day rain south central MA, eastern CT, RI, into southeastern MA. Highs 42-49, coolest in eastern coastal locations. Wind E up to 10 MPH.
TONIGHT: Cloudy. Spotty light rain, may mix with wet snow some interior higher elevations. Lows 35-42. Wind NE up to 10 MPH.
WEDNESDAY: Overcast. Rain/mix/snow likely. Highs 38-45 but may fall slowly during the day. Wind NE-E 10-20 MPH, gusty.
WEDNESDAY NIGHT: Overcast. Rain, heavy at times, may mix with or turn to sleet/snow at times favoring north central MA and southern NH. Lows 33-40. Wind E-NE 10-20 MPH inland, 20-30 MPH coast, higher gusts.
THURSDAY: Cloudy. Steady precipitation tapers to rain/snow showers. Highs 38-45, may spike to 45-52 Cape Cod. Wind NE-N 10-20 MPH inland, 20-30 MPH coast but may become variable Cape Cod, higher gusts probable.
THURSDAY NIGHT / FRIDAY: Mainly cloudy with additional rain/snow showers. Temperatures generally steady 38-45. Wind variable becoming N 10-20 MPH with higher gusts.
FRIDAY NIGHT / SATURDAY: Lots of clouds. A few rain/snow showers Friday night and a few rain showers Saturday. Lows 30-37 Friday night. Highs 41-48 Saturday. Wind N-NW 10-20 MPH.
DAYS 6-10 (APRIL 7-11)
Clearing trend to finish the weekend April 7. High pressure and fair weather April 8-9. Favorable sky conditions expected for solar eclipse viewing on April 8 (partial but greater than 90% coverage for WHW forecast areas while path of totality crosses far northern New England). Unsettled weather potential later in the period. Temperatures near to above normal.
DAYS 11-15 (APRIL 12-16)
A more west-to-east flow means variable temperatures and weaker weather systems to pass through, including a couple rain shower threats.
