They reissued the severe thunderstorm watch for the Northern part of the Delmarva. Lol why not just have left the original watch going

I think the initial watch was for the convection associated with the morning MCS, so they let that expire. Since the next  one is coming in from the west/further south they placed a watch in effect for areas west of the bay first, then with further evaluation added a new watch to adjacent areas to the east.
