Weather systems moving toward New England from the west and south will combine to form a storm that brings steady precipitation to the Canadian Maritimes. The storm development will happen close to New England, and will result in a period of light snow and rain on Thursday. Snow is possible at the start in most of Southern New England on Thursday morning. A southerly breeze will bring in milder air, resulting in a transition to chilly rain showers for most of RI, CT, and SE MA before there is any accumulation. Interior Southern New England and part of Northern New England could see a minor accumulation. See the map for details.
Chilly rain showers will end during the afternoon and cold, dry weather returns by Friday morning. Thursday’s high temperature will be near 40°. Friday will be bright and sunny, but colder, with highs in the mid 30s. Saturday looks like a fine late-December day. Lows will be in the 20s, and highs will be in the low to mid 40s with partly to mostly sunny skies.
A storm system moving out of the Gulf of Mexico will track northward along the East Coast and it likely pass east of Nantucket on Sunday night. Normally, a storm taking this track in the winter brings the threat of snow, but there will not be any cold air in New England, and, instead, Southeastern New England will get cold rain, with the chance of snow or mixed precipitation in Worcester County and north of the Mass Pike. The steadiest precipitation is likely Sunday evening.
The weather pattern will turn colder in the Northeast for the end of 2013 and the start of 2014. Monday should be partly sunny with highs in the mid to upper 30s. Tuesday and Wednesday will be in the 20s with a gusty north-northwesterly wind ushering in the cold air. The early outlook for New Year’s Eve from New York City to Southern New England is for dry skies and temperatures in the teens.
