Re Today: Watch the first 10 miles of the western shore of the bay in AA and Balt counties. This is the kind of day that low level helicity can jump dramatically from the enhanced SE winds coming up the rivers. Kind of a theory of mine that started when the F1 went through the next street down in 2006.

 

Noted..  Thanks. :yikes:
