Severe Weather outbreak for East Coast 7/27

Whoa today totally caught me off gaurd. I don't have time for a map for today so I apologize for that but here are my thoughts: deep instability, good lapse rates and decent shear will allow for storms to develop and become severe in particular the 1-95 corridor. A severe thunderstorm watch was just issued for SE PA, Maryland and NJ so the threat is just beggining. Main threats are large hail(hail parameters look good today) and wind with the shear in place. Another thing I have noticed that these shortwave events tend to be more severe than regular cold fronts so if today becomes one of the more severe days this year it will not surprise me. I'll try and get a update in later.
