A storm system in the central part of the country will push east, setting the stage for a widespread precipitation event across the central and eastern United States through Monday. A wide swath of accumulating snow is forecast from Nebraska to New England.

That’s the word this morning from the National Weather Service (NWS), who has issued a Winter Storm Warning for northern Fairfield County that will be in effect from 7 pm tonight until 6 pm Monday, February 2. The warning from the New York City office of NWS also includes northern New Haven County, as well as Orange and Putnam counties in New York.

Heavy snow, sleet and freezing rain are expected to affect interior portions of southwestern Connecticut and the lower Hudson Valley, according to the latest NWS warning. Newtown could see between 10 and 14 inches of snow, adding to what remains in place from Winter Storm Juno, which arrived January 26-27. Less than a tenth of an inch of ice may also come with the new precipitation.

The weather event is not expected to arrive until tonight, about three hours after the warning goes into effect. NWS is stating that most of today will be cloudy, with temperatures reaching a high of 28 degrees. Winds will remain, but not as strong as yesterday’s, moving 5-7 mph and creating wind chills between 10 and 20 degrees.

The snow is expected to arrive “mainly after 10 pm,” the weather service currently states. Temperatures will drop to a low of 17, and a light east wind will increase to 6-11 mph after midnight. Wind chill values will be between 5 and 10 degrees.

Chance of overnight precipitation is 100%, according to NWS, with new snow accumulation of 3 to 5 inches “possible.”

Monday will dawn with continuing snow “before noon, then snow, freezing rain and sleet,” according to the weather service. Temperatures will be “steady” around 20 degrees, but the wind chill will make it feel closer to 5-10 degrees. An east wind of 11-14 mph will “become north in the afternoon.”

Chance of precipitation for Monday remains 100%, with new snow and sleet accumulation of 4-8 inches, and new ice accumulation of 0.1 to 0.2 of an inch “possible,” NWS is posting at 8:58 am Sunday, February 1.

Wunderground.com, a weather dedicated website, is echoing NWS on some of its predictions. While Wunderground is showing 5-8 inches of snow for the Sunday overnight, that website is posting expectations of just 1-3 additional inches of “wintry precipitation” for Monday.

Wunderground’s staff is looking at a mix of wintry precipitation for Monday morning, “then periods of snow expected in the afternoon.” It is still a 100% chance of precipitation, according to that site’s professional, but a lesser amount arriving.

Monday night, according to Wunderground, will see “some lingering evening flurries or snow showers. Evening clouds will give way to clearing” with a low of -1 degree F.

No announcements have been made concerning school delays or closings as of 9 am Sunday, but The Bee will announce any updates as they are made.
