A brief ridge of high pressure will bring warming temperatures and some sunshine to the region today before coastal low pressure spreads light snow and blowing snow over portions of the forecast area Thursday and Thursday night, according to the National Weather Service (NWS).

Behind this system another surge of brutally cold air is expected for Friday and Saturday with dangerously cold wind chills likely, NWS says.

There is a 50 percent chance of snow showers today, mainly between 7 and 10 a.m., forecasters say. Skies are expected to clear as the day unfolds with a high of 22 degrees.

A half inch or less of accumulation is expected.
