Discussion

A strong cold front came through the region last night and it has ushered into the Mid-Atlantic region an unseasonably cold air mass for this time of year with its origins up in the Arctic region. Temperatures today will do no better than the middle 40’s for afternoon highs and there will be a strong NW wind producing much lower wind chill values. Temperatures are likely to drop to below-freezing later tonight bottoming out in the middle-to-upper 20’s across many suburban locations. With high pressure in control at mid-week, there should be plenty of sunshine on Wednesday; however, temperatures will remain below-normal throughout the Mid-Atlantic region.
