As a cold front swings through the region on Wednesday, two very different air masses will collide. The drier air from the northern Plains will meet the steamy air coming from the Southeast into the mid-Atlantic. The merge of dry air and very moist air will create favorable conditions for thunderstorms, some of which may be severe.
The main threats with these storms will be torrential downpours, damaging wind gusts in excess of 60 mph and even some hail. -SS
