The NOAA Storm Prediction Center in Norman, OK has put most of the DC Metro area under a Severe Thunderstorm Watch until 10pm tonight.
As an upper level disturbance passes over our area this afternoon and evening, instability will continue to lead to scattered thunderstorms, many of which will turn severe. Numerous Severe Thunderstorm Warnings have already been issued in Virginia.
The main threat from these storms will be damaging winds in excess of 60mph, and large hail.
Keep your weather radios on today and tonight as numerous more Severe Thunderstorm Warnings are expected.
As an upper-level low pressure system slowly progresses through today into this evening, strong rain and thunderstorms are likely throughout the area.
Isolated thunderstorms began developing early this afternoon after a morning of mostly to partly cloudy skies over much of the DC region. These thunderstorms quickly gained strength due to the unstable atmosphere, helped by extra heat from the sunlight.
Localized flooding is also a possibility, especially in Virginia where the ground is already over-saturated from the 3-6 inches of rain some locations accumulated yesterday.
These strong scattered storms will continue to progress and form over our area through this evening before the system moves out. Keep an eye on the skies and local weather reports as these continue to develop.
