Arctic Blast to Grip Region as Forecasters Track Sunday–Monday Winter Storm

Forecast confidence hinges on an uncertain coastal track.

Temperatures on Thursday will reach into the mid-40s, the last taste of ‘warm’ weather the area will see for some time, as snow and blistering temperatures will move in over the weekend.
Many will only get a light dusting of snow tonight before sunshing and 40 degree temperatures tomorrow.
Tracking evening rain, much colder air this weekend
Tonight will be chilly with a chance of evening snow and rain showers until 3 a.m.

Overview

  • Light snow and spotty rain taper by about 3 a.m., leaving little more than a dusting for most areas and minimal impact on the morning commute, with Thursday the warmest day near the mid-40s.
  • An Arctic outbreak arrives Friday night with temperatures crashing through Saturday, when highs hold in the teens and wind chills commonly fall 10 to 20 degrees below zero.
  • Snow is projected to develop around midday Sunday, peak Sunday night, and fade Monday morning, with the greatest totals favored inland and a risk of coastal mixing that could cut amounts near the shore.
  • Key models disagree on the storm’s path, with the GFS trending farther offshore and the European model closer to the coast, and forecasters expect better alignment by Friday.
  • A broad clash of tropical moisture and Arctic air is poised to produce significant snow and icing across parts of the South, raising the risk of major airline delays that could ripple into New England travel.
