* Watch for a severe thunderstorm and flood watch until 21 and 22 hours*
Both severe thunderstorms and flooding are in effect for a region stretching from Virginia to New Jersey through tonight due to the chance of storms, especially between about 5:00 PM and 10:00 PM. The top three hazards in any storm will be flooding rain, lightning and some damaging wind gusts.
Remember, seeing a severe thunderstorm means that the ingredients for severe thunderstorms are there, but it may or may not come together. However, if a severe thunderstorm warning has been issued for your location, that means a severe storm is on the way and you should seek shelter.

As of late this afternoon, a few storms have already developed along the Interstate 64 and Interstate 81 corridors, but there are no storms in the immediate metro area. Strong to severe storms are most likely during the evening hours – especially around sunset.
Calmer weather will emerge on Sunday, with rain chances diminishing rapidly in the morning and then skies clearing in the afternoon.

until tonight: Thunderstorms may slowly move into the region during the evening hours. The main threats are damaging wind gusts in some storms. Secondly, we have the threat of flooding in rain showers and lighting. At least half an inch of rain is possible for many of us, but a quick one or two inches of rain in the strongest thunderstorms can’t be ruled out.
Additional showers or weaker thunderstorms are possible later overnight as temperatures are in the upper 60s and low 70s. We’ll be monitoring rain amounts late into the night to make sure they don’t worsen flooding issues from previous storms.
Review of current time in The Washington Post.
Tomorrow (Sunday): The last of the rain will move out of the region in the morning as a light southwesterly breeze turns to the northwest, indicating that the cold front has passed. Southern Maryland may be the last place in the region to shake off the rain, perhaps by midday.
After the rains end, we all have a few more hours of clouds behind us, but afternoon skies will be bluer. High temperatures may range from 83 to 88 degrees, and humidity levels will slowly drop.

Strong to strong storm tonight
Tonight, the Beltway area should keep an eye on the 6-9pm window at most. This is when storms may be most focused on the DC area and the Interstate 95 corridor. A few storms may linger after that, but the potential for damaging wind gusts should subside shortly before the threat of flooding.
Small hail and frequent lightning are also possible tonight, even after the heaviest storms die down shortly after 9 or 10 p.m. Always remember “when it thunders, go indoors” — if you hear thunder, lightning is close enough to strike .
