Wind gusts to 75 to even 85 mph have been common with this system. Literally tens of thousands of homes and businesses are without power and the power may be off for some time due to the extent of the damage.
Updated the watch graphic (8:27pm EDT): The severe thunderstorm watch is in effect until 1am EDT:
I strongly advise people in these areas to bring items that can be blown about indoors and to listen for later weather information as the storms approach.
The record temperatures ahead of these thunderstorms will -- at least for a time -- be broken by the rain-cooled air. Temperatures may drop as much as 30° in five minutes!
