UPDATE: Wintry Weather to Impact Tuesday Roads

UPDATE:  Tuesday, Jan. 26, 3 PM–The National Weather Service has issued a weather alert notifying area residents of wintry weather impacting travel.

Light snow and sleet will likely mix with or transition to freezing drizzle through 4 p.m. This icy wintry mix is likely to continue into the evening commute, particularly away from the
coast.

A trace to few hundredths of an inch of gradual ice accumulation is possible on untreated and elevated surfaces, making for locally dangerous travel. Use extra caution if traveling into the evening.

Here’s the detailed forecast:

Tuesday Night:  Snow and sleet likely, possibly mixed with freezing rain before midnight, then a chance of rain, snow, and freezing rain. Cloudy, with a low around 30 degrees (wind chill values between 25-30 degrees). East wind 5-8 mph. Chance of precipitation is 70%. Little or no ice accumulation expected.

Wilton Library Closing Early

Wilton Library will be closing at 5 p.m. on Tuesday, January 26, due to the snowstorm and deteriorating driving conditions.

ORIGINAL STORY:  Monday, Jan. 25, 3 PM–A series of three low-pressure systems are expected to bring light- to occasionally-moderate snow and wintery mix to Wilton beginning Tuesday afternoon, Jan. 26 through Thursday afternoon, Jan. 28.

The three weather systems are forecast to move along a nearly stationary cold front stretched across the Mid-Atlantic region this week.

The Department of Emergency Services and Public Protection of the CT’s Division of Emergency Management and Homeland Security Department has provided a day-to-day forecast based on the latest computer models:

Tuesday, Jan. 26: The first low is forecast to bring a period of light- to occasionally-moderate snow (with a mix in southern CT) to our area starting Tuesday morning and continuing into Wednesday morning. A 1-3 inch accumulation is expected across most of the state. The NW Hills may receive a little more snow with accumulations up to 4 inches. Roads may receive a thin coating of snow for the afternoon rush hour. Highs in the low-30s.

Wednesday, Jan. 27: A second low is expected to form just south of Long Island on Wednesday afternoon. This low may stall near Nantucket and snow rotating around this low may impact eastern CT, RI and the Boston area Wednesday night into Thursday morning. An additional inch or two of snow is possible. Highs in the mid-30s. Once again roads may receive a thin coating of snow for the Wednesday afternoon rush hour.

Thursday, Jan. 28: A larger storm is currently expected to form off the North Carolina coast Thursday morning but then move out to sea well south of New England. On this track the storm would only bring another dusting of snow to the CT area on Thursday. If this storm takes a more northerly track then snowfall amounts could be higher. Highs in the low-30s.
