Discussion
An Arctic air mass has plunged into the Mid-Atlantic region and today will be very windy and cold for the middle of December. Temperatures will struggle to get above the freezing mark and wind chill values will be considerably lower given the NW wind gusts up to 35 mph. A "clipper" low pressure system will drop southeastward across the northern Ohio Valley today and move to our north by late tonight and early tomorrow. As a result, most of its snow will stay to our north - near and north of the Mason-Dixon Line - but a few snow showers cannot be ruled out around here later tonight into early Thursday and a dusting is possible with some slippery spots. The late week threat for snow has decreased as it appears that the next couple of waves of energy in the northern branch of the jet stream will likely not consolidate in time to produce snow around here.
