Flooding and severe storms threaten the D.C. area today.
A dynamic weather pattern has taken shape, and it will likely lead to more rain and storms throughout the day. Additional downpours on top of already saturated soil could lead to flash flooding, which is why the National Weather Service has issued a Flash Flood Watch through this evening. A few road closures due to high water are possible for the evening commute home this evening. As a matter of fact, some of our WeatherBug sites measured well over an inch, and in some cases over two inches from Sunday through this morning.

Another concern is the chance for severe thunderstorms this afternoon and evening. The primary threats include straight line damaging winds, and the possibility of an isolated, small tornado. We're not expecting to see the sun today, so instability should be limited, however, that should be offset by moderate wind shear and a dynamic weather pattern, which keeps the D.C. are in the zone of severe potential.

It looks as though we'll dry out a bit tomorrow with some sunshine, however, we can't rule out a few garden variety showers tomorrow afternoon. The next chance of more heavy rainfall is Wednesday night through Thursday. We'll keep an eye on that system and update accordingly as Thursday nears.
