The National Weather Service is calling for mostly cloudy skies, lower temperatures and perhaps a little more snow today in St. Lawrence County.

The storm that dropped as much as a foot of snow in some areas of St. Lawrence County and forced delays, early closings and cancellations at area schools yesterday and today is moving over New England and the Canadian Maritimes and northeast into the Atlantic.

Northwest winds of about 15 mph will result in some blowing and drifting of snow, the NWS says.

After high temperatures today in the teens and single-digit lows tonight, the temperature will rise into the 30s on Friday with snow turning to rain.

Temperatures are expected to be in the upper 20s Friday night with continued rain and snow showers.

For Saturday, the outlook is for a chance of rain and snow, then partly sunny skies on Sunday with highs in the teens.
