Does any snow actually occur with temps at or below freezing? Seems like rain turning to white rain and quickly ending.

Don’t know about the 80” snowstorm for southwest PA, but seems like at least one mega cold outbreak is more likely than not for later this month? Probably focused to our west so we don’t get the brunt.

Hoco deathband!

GFS has some digital blue!

It ain’t much, but euro had something for the cape storm? Like dusting -1”?

I think it bounces around as much as anything in mid and long range, but it’s pretty deadly inside D5

Nina’s are exhausting

If it wasn’t 48 when it started, we would have definitely gotten a couple tenths in a matter of 3-5 minutes. Temp dropped to 37.

Instant mini dusting

Ripping snow and graupel

Since the 12-20” idea that one GFS run threw out is obviously gone, we’re trading between the former Euro AI idea of a widespread 1-3” for this solution where some lucky spot may get 6-8” and some people are going to get almost totally skunked.

Just had some flakes with temps of like 48

Off the top of my head I can’t think of a great analog for this, but I don’t have the photographic memory that @psuhoffmanand others do. I’d guess New England has some experience with these? But you’re looking at a ULL deepening and capturing a surface low basically on top of us. So this is all dynamics driven with strong upward motion. There’s no great moisture feed off the ocean, no WAA or CCB well defined. So I guess we’re looking at where the best lift from the jet streak exit region and the ULL falls? Maybe there will be some frontogen at like 700mb that will produce some of those higher totals? It’s totally a Nowcast. 1-6” would be a reasonable range.

This is totally a thoughts and prayers event. 80% going to be broken hearted. Don’t think I’ll be relaxed until I’m shoveling. If we could be objective though, it’s potentially a really cool event to watch just from a dynamics perspective.
