That is the thing....the NARCAN algorithm excels at accurately conveying snowfall given the modeled thermal profile. If the model is too warm, then the map will be off.
I still say at the end of the day, we should be able to muster enough n stream insert for a good foot of snowfall, given the -NAO/PNA tandem. I can't imagine the well is that dry with the PAC that active.
We will know by 12z tmw.
