A cold front marching into the area, has ignited a line of thunderstorms this evening, mainly in our northern counties. While the threat of severe weather has ended, we do have the concern for flash flooding with any storms given the moisture antecedent conditions. Remember, if you encounter a flooded roadway, turn around and find an alternate route. The storms should end by 9 or 10 p.m. with gradual clearing overnight with mild lows in the 70s in town with 60s in suburbs. In the wake of the front, northwesterly winds will bring in less humid conditions overnight and early Friday. This will set the stage for sunshine and a gorgeous end to the work week. Despite the lower humidity, it will still be rather warm with highs in the middle to upper 80s. The weekend looks pretty good overall. The only fly-in-the-ointment will be Saturday when a weak disturbance will arrive, providing the risk of showers, especially in West Virginia, Virginia, and southern Maryland, with lower humidity. Otherwise, we will see some sunshine with highs in the 80s. Behind this disturbance, we partly to mostly sunny and hot conditions for Sunday.
Have a great finish to the work week!
