Garden-variety or severe?

Twenty minutes of video compressed are into 20 seconds showing the thunderstorm on the afternoon of September 18, 2012.

When the line of thunderstorms approached Tuesday afternoon I set up the video camera pointed outside the window. I was in Reston, Va. and severe thunderstorm warnings were being posted throughout the area. The storms looked impressive on radar.

After 20 minutes from setting up the camera the storm was over. We had briefly gusty winds, heavy rain, but nothing severe. I know that other areas had flooding rain and damaging winds, however.

Peak winds were generally in the 45-60 mph range. Reagan National Airport gusted to 61 mph and BWI 47 mph. Scattered reports of downed trees resulted from these strong gusts.
