Discussion

A slow-moving frontal system to our northwest will inch its way into the Mid-Atlantic region this weekend and then grind to a halt. Low pressure will form along the stalled-out frontal boundary zone enhancing the chance here for showers and thunderstorms and some of the rain this weekend can be heavy at times. High pressure off the coast will resume control early next week and it'll stay on the warm, humid and unsettled side. Looking ahead, there are some favorable signs for a refreshing air mass to move into the northeastern part of the country by the end of next week or during the following weekend.
