Looking over models at 500 and at surface. I don't think many realize how close we were to a mecs. Look at nam 12k for example. That north vort now phases in late and you have a bombing low the second it gets off shore.
From what I under stand that north vort is what is killing off the moisture. We Keep weaking and getting that north vort out the way. The better our chances at at 1-3/2-4 event.
I could be wrong but these type of storms seem to always come more north than forecasted. 4" is my guess for my area but would love to see a PHL jackpot.
