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 mid-to-upper 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 near 30 degrees across some 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.
