High pressure – in our case, fair weather -- is building into New England and the Northeast for a few days, and this will mean gradually but steadily improving weather.
Sunshine is limited Wednesday, with ample moisture in the lowest levels of the atmosphere causing new clouds to build and billow through the day. This will generally blot out the sun and ensure a cool air will continue with highs only near 50, some 8 to 10 degrees milder than Tuesday!
Gone, also, are the rain and snow showers as the final flakes depart from eastern Maine and the final sprinkles nudge south of New England.
Clearing is expected Wednesday night as dry air takes hold, ensuring a cold night with lows in the 20s. We’ll likely have a bright Thursday with similar temperatures to Wednesday, but a warmer feeling thanks to the sunshine.
Meanwhile, a big storm over the Plains States will bring blizzard conditions there, while scooping up warmth ahead of its track and launching it toward New England. This will create a round of showers Friday night into Saturday morning, thus opening the door to highs around 70 Saturday afternoon.
The showers should come to an end on Saturday in most of New England, except perhaps Cape Cod. Sunday may not be quite as warm, but should start pleasant ahead of a larger storm that will deliver rain Sunday night into Patriots Day for the Boston Marathon.
Although this raises concerns of a similar scenario to last year with rain and cool temperatures, our exclusive NBC10 Boston/necn Forecast System is showing a 60 to 70% chance of rain Monday.
