There is the potential for roadway and airport delays during the morning and midday hours Friday due to downpours in the area.
While the storms will be random with hit-and-miss fashion, they have the potential to cause poor visibility for a short time, as well as flash and urban flooding.
Commuters outside of the immediate Washington, D.C., area can also be affected over the I-66, I-70 and I-95 corridors.
A couple of the storms can be severe, bringing damaging wind gusts and power outages to a small number of communities.
Part of the same system heading into the Washington, D.C., area early Friday brought more than 900 flight delays to the Chicago area Thursday.
Showers and thunderstorms will affect parts of the mid-Atlantic states Thursday night into Friday as a push of cooler and less humid air sags southward.
During the afternoon and evening, the storms and their downpours will tend to settle over southern Virginia and North Carolina.
In the wake of the front pushing southward, temperatures will trend from slightly above-average to slightly below-average for a couple of days, Saturday and Sunday. Warm and humid air will build back next week.
