Snow then A Warm Up

Been eyeing this snow for a about a week now. Not a big snowfall, but bigger than anything we've have this winter so far. Details:

1. Long duration snow event from Tuesday morning to early morning hours of Wed.
2. Snow will be mainly light, but some heavier bursts are possible.
3. Unusual Snow Set-up: No strong surface low pressure at all.
4. Key ingredients are a potent upper low in the Midwest, and a strong surface High in SE Canada.
   1. The High provides a bubble of cold stable air for warmer air to override and produce snow.
   2. The upper low provides a steady stream of moisture right into our area.
   3. Cannot overstate how important that High pressure is in making this snow possible. Without it, little snow if any at all. But with it, several inches.
5. Total snow = 4-6” expected by 5 am Wed morning.

 
Wild Cards:

1. Temperatures soar much higher than expected into the mid-30’s and the snow is wet and melts at first (VERY UNLIKELY)
2. Snow could be fluffier than I have giving up deeper accumulation (UNLIKELY)
3. Enhancement of moisture off the ocean from Low developing off the NC coast on Wed. This would keep us in the snow through mid-morning Wed giving us some additional snow. [One model is doing so this evening]. (POSSIBLE)

 
This will be our largest snow of the winter so far. It seems to be that we will be in a regional sweet-spot for this one. My confidence in the total snow is lower than usual due to the wild cards I listed above.
