DAYS 1-5 (MARCH 17-21)…
The volatility of March will be apparent during this 5-day period, starting with a mild St. Patrick’s Day which includes the chance of scattered showers and thunderstorms with gusty winds and small hail this afternoon as we get relatively warm at the surface and have cold air aloft, which is an unstable set up. A strong cold front passes on Friday with a few rain and eventually snow showers, gusty wind, but most importantly bringing a delivery of cold air that will last through the weekend. After fair weather Saturday, a storm system that has traveled cross country will make a run up the East Coast late Sunday into that cold air, departing early Monday, but in the process of its passage may leave a significant snowfall over at least part of, if not most of the region. With the event toward the end of this period, details are still not possible to discern, but fine-tuning will be in progress throughout so you have as accurate a lead-up and final call as possible. In the mean time just be aware of the strong possibility of a significant winter storm as spring officially gets underway.
TODAY: Lots of clouds and areas of fog to start, then variably cloudy including partial sunshine, leading to scattered showers and possible thunderstorms after 2PM, some of which may include small hail. Highs range from near 50 South Coast to the lower 60s interior MA/NH. Wind SW increasing to 10-20 MPH with higher gusts. Also, briefly strong wind gusts are possible near any showers and thunderstorms.

FRIDAY: Variably cloudy. Scattered rain showers mainly late morning through mid afternoon, may end as snow showers in some areas. Temperatures steady in the 40s in the morning falling to the 30s in the afternoon. Wind W 15-25 MPH with higher gusts, shifting to N.
