DAYS 1-5 (MARCH 20-24)
The Vernal Equinox occurred at 5:37 a.m. .. Spring is here! You know I always warn about thinking any threat of winter weather is over just because spring arrives. Well, we won’t worry about any winter weather threats right now because even though we know what late March & April can do to us here, we have a nice weather pattern to start off the new season as high pressure moves in today and sits atop New England for several days, through Tuesday in fact. Today’s temperatures will be most uniform across the region due to a westerly air flow. Sunday through Tuesday, warmest weather will be inland during the day while coastal areas are cooler due to sea breeze development. Nights will be chilly due to radiational cooling from the combination of clear sky and light wind, though we may see some ground fog formation in lower elevations each night as the temperature makes a run for the dewpoint during its overnight fall. By Wednesday, an increase in clouds and a more regional southeasterly air flow ahead of a warm front will likely make this a cooler-feeling day, and there may be some light rainfall around later in the day or in the evening as the warm front arrives.
TODAY: Mostly sunny. Highs 52-59. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 26-33. Wind W under 10 MPH.
SUNDAY: Mostly sunny. Highs 48-55 coast, 56-63 inland. Wind variable up to 10 MPH with coastal sea breezes.

MONDAY: Sunny. Highs 48-55 coast, 56-63 inland. Wind variable up to 10 MPH with coastal sea breezes.
MONDAY NIGHT: Clear. Patchy ground fog interior lower elevations. Lows 33-40. Wind variable up to 10 MPH.
TUESDAY: Sunny. Highs 49-56 coast, 57-64 inland. Wind variable up to 10 MPH with coastal sea breezes.
TUESDAY NIGHT: Clear then increasing high clouds. Patchy ground fog interior lower elevations. Lows 36-43. Wind SE under 10 MPH.
WEDNESDAY: Mostly cloudy. Chance of light rain by late-day or evening. Highs 48-55. Wind SE 5-15 MPH.
DAYS 6-10 (MARCH 25-29)
Warmest day except cooler South Coast March 25 ahead of a cold front, the parent low pressure of which passes north of the region late March 25 and early March 26 when a better shot of rain occurs, before it turns breezy, colder, and dry later March 26. High pressure brings mostly fair weather, a cool start then moderating temperatures in the March 27-28 period before the next disturbance brings a chance of unsettled weather by March 29.
DAYS 11-15 (MARCH 30 – APRIL 3)
Based on current anticipated timing of systems and being near the border of a mild US Southeast and a cold eastern Canada, expecting a drier but chilly finish to March and a warming trend the first few days of April marked by some unsettled weather during the transition.
