Both the 12z GEFS, 12z AI-GEFS, and the 12z AI-ENS have several warning level hits from I-95 and points west. We may not be that far off from something here.
Yes, THAT is how we win and its inside an established pattern. Not a wave breaking into something as we're setting up. Really would like to see at least a slightly -NAO to help lock in our cold air though.
Bittinger and Frostburg mesonet sites showing a flip to westerly winds. Looks like the front is starting to crest the Eastern Continential Divide. Here's hoping we don't torch into the 70s prefrontal.
We still have a week to find our fail point. Could be any of the following:
1.) High slides offshore and we nibble away at CAD with antecedent southeast winds.
2.) Last minute de-amplification trend.
3.) Primary drives into Pittsburgh and it's just cold rain.
The Canadian high on the 06z Euro is a tad east for my liking. That setup can erode the CAD situation with prolonged southeast winds. Would like to see that backed up further west into the St. Lawrence River Valley.
