DAYS 1-5 (MAY 3-7)

Low pressure passed by to the southeast of New England overnight giving a period of rain to far southeastern MA, the last of which is exiting Cape Cod early this morning. As the low pulls away, a pool of cold air associated with an upper level low crossing the region will create a lot of stratocumulus and cumulus clouds, some of which can produce a pop-up shower, otherwise it’ll be a day of limited sun, an active breeze, and a cool feel to the air, but with mainly dry conditions. The upper low pulls out tonight and we clear up but are quite cool. High pressure building across the Mid Atlantic and off the coast Monday and Tuesday will promote fair weather and a warming trend for our region, though it will become rather breezy, especially on Tuesday, which will also be the warmest of the two days. As is usual, a southwesterly air flow will be modified by cooler ocean water and it won’t be able to warm up as much along the South Coast and especially across Cape Cod and the Islands. The midweek – Wednesday and Thursday – will feature unsettled weather as a trough of low pressure approaches and a frontal system triggers showers and possible thunderstorms on Wednesday. After the front passes by on Thursday, it will slow down while another wave of low pressure moves up along it, bringing the chance of rain that day.

TODAY: Early-morning overcast southeastern MA while rain exits Cape Cod. Otherwise, lots of clouds, limited sun, and the chance of a passing shower. Highs 54-61. Wind NW 5-15 MPH, few higher gusts.
