Yeah I knew it when the air didn't have the feel of an outbreak day like it did on 4/16/2011. On top of that as you stated the winds were calm and that is definitely not how it goes around here on most high end days.
Agreed On the big days here it is usually very windy even outside storms. 4/16/2011 being the prime example. The problem is this was a cry wolf event and so when we do get a big one that may be an issue.
I don't see how they maintain the MDT. This should be a Slight to be honest. A high shear low cape event. I think they walk it back to ENH and shift it east a bit but we shall see.
