Questions that still need to be answered...
Temperatures and dewpoints?
Does a secondary form and if so where?
How strong is the high pressure to the north?
However..perhaps the biggest question is how much QPF actually makes it into the region?
I think at this point is the biggest unknown... Not only is how much QPF makes it into the region while the temps are supportive of frozen but how much over all QPF?
How much WAA will there be if the majority of the precipitation rides west of the region and then we are only dealing with QPF from the potential coastal low?
Unfortunately all these might come down to the last couple hours before the event...
On this map I believe Pittsburgh PA will start as brief ice and go to rain and then change back to snow later in the period..same thing stretching up towards Erie Pa...
