Looks like the follow up is for C/S VA instead of NC... does this trend continue? We'll find out after the commercial

I'm no expert on the stratosphere, but it looks like it's about to split into two, which promotes more HL blocking?

Bad news, aigfs is an op model so little confidence in its blizzard scenario. The GOOD news is ensembles (including euro and ai euro) do have some support for that scenario by undercutting a s/w under HL blocking. The ens means is smoothed out, but if you can “read between the lines” you can see a sharper trough or ULL swing across the mid-south towards us from feb 13-16. -

As a glass half full kind of guy, I’m with you. The very fact that NC got their HECS should give us a lot of optimism about our future winters. We will get ours one of these winters, and many more to come. Instead and unfortunately, some choose to look at it as a zero-sum game where we get mad when folks south of us are getting more snow than we do. I also don’t think we’re done with winter yet, but if we really are, we have an El Nino to look forward to. It’ll probably be a milder winter than the last two, but at least we’ll have our chances with an active STJ. -
Lock it up

32 now. But not much melting if any

Since I moved back to the area, we've gotten zilch in March... so the WDI is off the charts. -

Strat warming is on the atlantic side, so that should knock the AO back down. Can already see hints of it doing that in the dashed mean line starting to turn downwards right at the end. -

Both GEFS and EPS have a follow up wave on the 15th after a cutter, with a cold enough airmass for us. I'll be watching that one. -

Looks like a potential swfe overrunning event from midwest to NE, but could include us depending on how well we hang onto the cold. Usual disclaimer applies -

Nothing new. Lived through some bad runs and plenty of close misses here. At least everything is still white here with 6 ft snow piles as if we had just gotten a flush hit. -

It does show some undercutting energy that could give us a mixed event or moderate snow if we could hold onto enough cold. Early for details, but it’s not a total shutout
