DAYS 1-5 (MARCH 22-26)
High pressure sits atop New England early this week, continuing the very nice weather stretch that we started over the weekend. Once again the coastal areas will be cooler each day due to a sea breeze developing, and each night the inland lower elevations will be colder due to radiational cooling. High pressure partially gives way Wednesday as low pressure passes south of the region and a warm front approaches from the southwest ahead of another low pressure area heading for the Great Lakes, resulting in a general increase in cloudiness and a southeasterly air flow which will keep the region more uniform in temperature, the result being a cooler day for inland areas that won’t be able to warm as efficiently as the next 2 days. The warm front may bring a touch of light rain Wednesday evening as it passes and opens the door to a warmer southwesterly air flow for Thursday. Although this air flow will result in cooler conditions for the South Coast, especially Cape Cod and the Islands. The low heading into the Great Lakes will be passing north of our area Thursday night and Friday, dragging a cold front through when we will see our best chance for rain shower activity. We need rain as we have had a very dry March so far. However, this does not look like it will be a very significant rain producer. What it will do is introduce a cooler air mass later Friday – with the temperatures that day highly dependent on the timing of the cold front. The air behind it will probably be cold enough to allow a mix or snow should any precipitation linger long enough, but at the moment this is not very likely to occur – more of a remote possibility.
TODAY: Sunny. Highs 50-57 coast, 58-65 inland. Wind variable up to 10 MPH with coastal sea breezes.
TONIGHT: Clear. Lows 33-40. Wind variable under 10 MPH.
TUESDAY: Sunny. Highs 50-57 coast, 58-65 inland. Wind variable up to 10 MPH with coastal sea breezes.
TUESDAY NIGHT: Increasing high clouds. Lows 36-43. Wind SE under 10 MPH.
WEDNESDAY: Mostly cloudy. Highs 49-56, coolest coast. Wind SE 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Chance of light rain. Lows 41-48. Wind SE up to 10 MPH shifting to SW.
THURSDAY: Partly sunny. Highs 48-55 Islands / Cape Cod, 56-63 remainder of South Coast, 64-71 elsewhere. Wind SW 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy. Rain showers likely. Lows 48-55. Wind SW 10-20 MPH.
FRIDAY: Mostly cloudy. Rain showers likely. Highs 57-64, may fall quickly late-day / evening. Wind SW 10-20 MPH shifting to NW by late-day.
DAYS 6-10 (MARCH 27-31)
Early call on the last weekend of March (27-28) looks dry/cool Saturday, still on the cool side but watching for the arrival of low pressure from the southwest Sunday. As this system moves through into March 29 we’ll have to watch closely as cold air will be nearby so there is a slight chance we’ll be dealing with a rain/snow line somewhere, but leaning toward a rain event for now. Rain or snow, any precipitation we can get is needed. Dry/chilly ending to March (30-31).
DAYS 11-15 (APRIL 1-5)
The trend in the early days of April is for a warm-up that may not really take hold until later in the period as we’ll be near the border of Canadian cold while US Southeast warmth tries to push in. It may be unsettled during the transition.
