OP here.

I know, right? The temperature is the biggest uncertainty. It's impossible to predict accurately when the temp is marginal and hovering between freezing and above freezing. If temps stay above freezing, we'll get no accumulation. If temps dip just a smidge, and the inverted trough is positioned just so, then we can get as much as much as 8-10 inches in parts of the region. It's one of those storms...

Temps like that create ice/sleet and not snow. This could be snow-crete part 2[/quote]

No and no. If ground temps are above freezing, the snow just melts on contact. There will be no snowcrete under any circumstance for this storm.

It's weird you don't understand that the last time we got snowcrete, it was because the ground and the air were well below freezing BEFORE AND AFTER the storm, and that the storm had hours of sleet because there was a warm layer sandwiched inside the cold airmass. The sleet froze rapidly on contact with the ground. It was wild, and has never happened in the 20+ years I've been living in the DC area. It's not likely to happen again any time soon since you need very unusual conditions, which usually do not verify for us.

Again. No snowcrete.
