High pressure off the east coast that has been in control of the overall weather pattern around here for several days will begin to break down as we head to the weekend. A slow-moving frontal system to our northwest will inch its way into the Mid-Atlantic region this weekend and then stall out. Low pressure will form along the stalled-out frontal boundary zone over the weekend enhancing the chance for showers and thunderstorms and some of the rain can be heavy. 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 following weekend.

There is a chance that some of the rain that falls this weekend can be on the heavy side.
