Severe Thunderstorms Well East of District

By Jason Samenow

* Severe T'storm Watch East of District (Map) until 11 p.m.
* Heat Advisory Monday, Noon to 10 PM (except far N&W: map) *

After matching the previous hottest day of the summer (the mercury reached 96 at DCA which it also hit on July 16), an intense line of thunderstorms has developed over northeast Maryland and should pivot southward over the next several hours. These storms may produce dangerous lightning, torrential rain, and very strong winds. Most of the action should stay east of a line from Baltimore to Annapolis. However, we'll keep you posted if the storms get any closer to the metro region...

Monitor radar and severe warnings issued by the National Weather Service on our Severe Weather Tracking Station below. Also, comment below with conditions where you are. And see our full forecast through Wednesday.

Watching an outflow boundary on radar pushing south of Baltimore. Will it be the focusing mechanism for some storms in the metro area?

NWS has cleared all of the local area from the severe thunderstorm watch.

The storms are running into a more stable airmass and we're losing day time heating...
