March 12th Update

All systems go for a big March Nor'easter on Tuesday

The third Nor’easter of the month is on the doorstep. This one promises to bring heavy snow and strong wind to New England Monday night through Tuesday, with effects lingering through the midweek.

Snow will develop after midnight in Southern New England, and it will be steady by 4-5 am. A few inches will likely accumulate by dawn, with heavy snow continuing through midday Tuesday. It will snow through the afternoon, but the heaviest will likely be over by 12-2 pm. Snow showers linger into Tuesday night, with a coating-1″ additional accumulation possible in the evening. The brunt of the storm is from 4 am – 2 pm Tuesday. 1-2″ per hour snow rates are possible.

This does not look like a very wet/heavy snow for most of Southeastern New England. The exception may be on Cape Cod and the islands where the air will be just a bit warmer. I have kept the snow totals a little lower there to account for denser snow, but, if it’s not very wet/heavy, then the jackpot for this storm could be from New Bedford to Plymouth to Falmouth. The heaviest snow in CT will be in the eastern half of the state, particularly in the northeast hills of Tolland/Windham Counties.

The wind will gust 35-45 mph in RI and interior SE MA, with 45-60 mph gusts for coastal SE MA, Cape Cod, and the islands. Nantucket may have some gusts over 60 mph. Once again, power outages are possible.

Expect lingering snow showers on Wednesday with no accumulation during the day. Flakes cannot be ruled out Wednesday night, with another coating-1″ possible by dawn on Thursday, especially inland.

Chilly weather persists through the week. Highs will only be in the 30s to low 40s between Thursday and Monday, and yet another storm is possible in the middle of next week as spring begins. Enough already!
