With air temperatures are in the upper 90s, and dew points are in the upper 60s, its easy to see why a number of storms have popped up over the region this afternoon. I doubt any of these storms will become severe, due to a lack of sheer in the atmosphere, but heavy rain and dangerous lightning are possible in some of the storms (I saw about 20 cloud-to-ground strokes of lightning with a storm that moved just east of my Silver Spring office at about 12:30pm today...). The best chance of for storms will be south and west of DC.

The National Weather Service has extended the slight risk area for severe weather to include the entire metropolitan DC area for tomorrow... damaging winds area the greatest risk.
