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 -

And btw, the pattern we just had really delivered. We just didn’t have all of the luck on our side. Could just as easily have had 2 blizzards in one week, so if I see Jan 2026 analog again, I’ll by honking loudly about it. -

Looks like a big change/flip in the long range over the last 24 hours. One run does not make a trend, but 3 00z/12z runs in a row just did a resounding repudiation of the freezing february pattern. Interestingly, AI ensembles led the way on this. We may be able to thaw this glacier out by presidents day weekend, or if its not as warm as progged, weekend after. Unfortunately we may have lost big snow chances for the next 2 weeks, and by the time it gets cold again with the SSW effect and weak MJO 3, we’d be running out of time by that point. Not saying it won’t snow then, but more likely to be smaller to moderate events. -

No prob. I like the effort you're putting into comparing model forecasts, though. -

Did you check the ensembles for that time period? We don't really go by op models beyond day 5-7 or so
