Severe Thunderstorm Watch Until 8 AM

Mother Nature's wake up call is coming in from the west, bringing a history of vivid lightning, gusty winds, and some large hail.  These storms developed yesterday afternoon in Michigan and tracked through Ontario before making the turn southeast towards us overnight.  These storms are riding along a warm boundary in the mid levels of the atmosphere and are being fed into that.  The result of the strong and severe thunderstorm activity has been to throw up a short-fused Severe Thunderstorm Watch until 8 AM for the Philly metro, all of Delaware, and South Jersey south of 195.

A smaller area of storms has developed and moved into the burbs now but the brunt (as of just before 5 AM) is back across Berks and Lancaster Counties -- containing large hail and gusty winds...along with lots of lightning.  That will pass through the Philly metro over the next couple of hours as it moves east-southeast. It should hit the city by 6 AM and the Shore by 7.  Storms should come to an end about an hour or so after that nastier line (assuming it holds) passes through your location.
