The freezing night that followed yesterday's snow storm has left roads in southwestern Connecticut with hazardous patches of ice early this morning -- and the National Weather Service warns there is little prospect for melting the snow and ice later today.

That's because the daytime high temperature today will rise only about to the freezing mark of 32 degrees, the NWS says, with an east wind around 9 mph.

Overnight, there is a slight chance of snow and freezing drizzle late and into early tomorrow. Skies will be cloudy with a low temperature of about 30 degrees.

Tomorrow, there remains a chance of cold drizzle in the morning, then changing to rain after 1 p.m. as temperatures rise to a high of nearly 50 degrees. The warming, wet trend is expected to produce areas of fog in throughout the region.

Nighttime tomorrow is likely to bring more rain and fog, mainly before 1 a.m.

More warm weather is the in the forecast for Tuesday, which the NWS says will be mostly sunny, with a high near 51 degrees and a west wind 5 to 8 mph, later increasing to between 13 and 16 mph. Gusts could be as high as 28 mph.

Wednesday, the weather service predicts, will be sunny, with a high in the low-40s.

Saturday morning's snowstorm dropped from 4 to 7 inches of snow across southwestern Connecticut , but cleared out by early afternoon.

In the wake of the region's first significant snowfall of 2012, temperatures plunged last night to the low-teens -- and below -- overnight.

Few problems were caused by the storm. Unlike the October nor'easter that left more than 800,000, the storm had a minimal impact on the state's power companies, with no storm-attributed outages reported by either Connecticut Light & Power or United Illuminating.

No serious accidents or lane closures were reported on the region's major roads by Sunday morning.

Metro-North Railroad maintained service on or close to schedule all day.

Many community events and social activities for Saturday were cancelled early in the day because of concerns about travel safety`.
