DAYS 1-5 (FEBRUARY 24-28)
The final 5 days of February are here to remind us it’s very much still winter. After our warm anomaly yesterday, we’re back to a cold reality today as high pressure in eastern Canada feeds plenty of polar air into our area. The cloud cover you see this morning is not from our coming winter storm but from an advanced area of moisture which is drying up as it moves eastward, passing to our south. These clouds will yield to more sun during the day today before our storm forerunners move in this evening. Low pressure will be heading toward New York from the Ohio Valley then redevelop and pass just south of New England on an east northeast track Friday and Friday night. This is a wintry precipitation set up for us with a cold high to the north, so we all start out as snow, and a good portion of the region stays snow through the event. The wild card remains how much warm air works in aloft to change that snow to sleet, and at this point I think anywhere from the South Coast to the I-90 area is in the game for this. If there is a change to rain at all it will be for a briefer time along the immediate South Coast and most likely Nantucket and Martha’s Vineyard. Areas that have mixed or changed should end as snow or snow showers Friday evening as colder air is ready to wrap right back in around the departing low pressure area. With all of this in mind, when it’s over, I expect accumulations to be 1-3 inches over the islands and perhaps immediate beaches on the South Coast, 3-6 inches from there to just south of I-90 including much of southeastern MA, RI, and eastern CT, and 6-10 inches north of there through the bulk of MA and southern NH, with a few spot accumulations of up to 12 inches favoring north central MA and interior southern NH. After our storm, it’s cold and mainly dry for the weekend and Monday, to end the month, with the exception of the chance of some snow shower activity Sunday as a reinforcing cold front moves by.
