DAYS 1-5 (FEBRUARY 7-11)…
This update will nix in-depth discussion and save it for comments below as information comes in today. Overall, we’re still looking at a nice day today with plenty of sun and snow-melting, above-freezing temperatures. Clouds come in late from 2 directions: a high cloud shield from the south ahead of a developing ocean storm, and a band of clouds from the north along the leading edge of colder air, a cold front, which may trigger a snow shower in southern NH and northern MA by evening. The storm developing offshore will grow into a large-sized and very powerful ocean storm, but its orientation and size will be enough to throw moisture in the form of accumulating snow back into southeastern New England Monday. We’ll continue to watch the interaction of pieces of energy in a larger scale low pressure trough Tuesday-Thursday with additional opportunities for snow possible. At this time it looks like a second system may deliver a period of snow early Wednesday to parts of southern New England, but again timing and location of any snow area is uncertain, so just follow later updates.
TODAY: Sunshine much of the day, fading late behind advancing high clouds from the S, and also some cloudiness arriving in southern NH and northern MA from the north at the end of the day. Highs 38-45. Wind SW up to 10 MPH.
TONIGHT: Mostly cloudy. Chance of a snow shower southern NH to northern MA early. Snow developing southeastern MA and southern RI overnight. Lows in the 20s. Wind NW to NE 5-15 MPH with higher gusts.
MONDAY: Cloudy. Snow expanding northwestward across the region and continuing much of the day before becoming more intermittent and scattered at night. Blowing snow likely. UPDATED ACCUMULATION FORECAST… 4-8 inches except 8-14 inches in portions of southeastern MA and under 4 inches in north central MA and southwestern NH and under 8 inches outer Cape Cod and Nantucket. Temperatures steady in the 20s but may reach the 30s for a while immediate coast south of Boston and Cape Cod / Islands, before falling later. Wind NE 15-30 MPH with higher gusts especially coastal areas and southeastern MA. Blizzard conditions may exist in these areas for a few hours.
TUESDAY: Partial clearing but snow showers possible during the day/evening. Cloudy with a risk of snow returning overnight. Lows around 20. Highs around 30.
WEDNESDAY: Cloudy with a chance of snow morning. Variably cloudy with a chance of snow showers afternoon. Lows around 20. Highs around 30.
