Another winter storm moving toward southwestern Connecticut from the southeast continues to pose the threat of snow and sleet this week, although the impact is trending later than earlier forecasts.

Tomorrow through Thursday are subject to a "Hazardous Weather Outlook" from the National Weather Service, with the potential for "significant" snowfall most likely Wednesday night.

But there is the chance of snow and freezing rain beginning tomorrow morning, off and on, through Thursday morning, the NWS warns.

Today will be sunny, but again very cold. The daytime high temperature is expected to be about 17 degrees and the wind chill could feel as though it is minus-9 degrees because of a north wind 5 to 10 mph, then becoming west.

There is a slight chance of light snow after midnight.

That chance of snow continues tomorrow mainly before 2 p.m., then the skies will clear with temperatures rising to a high of 35 degrees.

Tomorrow there is a chance of snow again, with a low of around 27.

On Wednesday, a mix of rain and snow is likely before 4 p.m., then rain and sleet. The daytime high is expected to be about 36 degrees, according to the NWS. New precipitation amounts may be between a quarter- and half-inch.

The rain and snow mix is expected to become all snow late Wednesday. The accumulations could be at least 1 to 2 inches.

By Thursday, snow is possible through the early-morning hours, tapering off after 7 a.m. The day should gradually become clear with a high temperature of about 35 degrees, the weather service predicts.
