Discussion
A cold, dry air mass is in place across the region as we begin a new work week, but there is plenty of moisture headed in this direction from low pressure moving towards the Ohio Valley. A mix of snow, ice and/or rain is likely to push into the area during late afternoon hours and it could change to all snow for awhile. In fact, there is a chance for a burst of heavier snow an hour or two after the onset of the precipitation as "evaporative cooling" will cause a quick drop in temperatures. Accumulations of anywhere from a coating to 2 or 3 inches are possible during this event with the higher amounts associated with spots that do receive bursts of heavier snow early this evening. Given the cold ground conditions, there can be some slick spots from late today through tomorrow morning. Another storm system will head towards the Carolina coastline by Thursday and its precipitation shield is likely to stay to our south and east.
