Feb 1986 was pretty good. 13” at BWI

Wow good thing I was only 4 and there was no internet or I would have been cliff jumping in 85-86.

@North Balti Zen and @dailylurker all like

whoa baby...they're a double bunner.

Weeklies apparently might put your weenie back in the bun and EPS signal for 20-21st isn’t terrible…

GLL needs to GTFO

Agree. I think they’re done pretty much regardless. Even if they fall into a WC spot, they’re getting bounced in the first round.

Jesus Ravens. Even a seemingly disastrous game turns into a heart attack.

I remember how that pattern developed in 17-18. Looked like an amazing overrunning pattern at range and the models were keying in on a storm from D8-10, but then the cold push overwhelmed it and it was suppressed to hell and gone. We got a couple minor events in a cold and dry period.

Great thread this morning from @griteater. His best analogs for this MJO progression at this time of year in a Niña are 95-96, 01-02, and 17-18. Three wide ranging outcomes there showing @psuhoffmans reminder that luck always has a big role to play.

Seeing videos and images out of Mayfield, Ky. Staggering devastation. Got to be some EF4 level damage.

Yikes, kiss of death

Agree with everyone else. Tons of very cold air in Canada. Not like last year at all where the blocking was just blocking in modified Pacific air masses. That’s legit arctic air in Canada. We just need a small slice.

LOT to like on that GEFS run. -AO and -NAO builds from east-based to west-based by post-Xmas. And the -EPO keeps nudging eastward in time pushing the western trough more into the Rockies and high plains. And GEFS has actually been accelerating the changes rather than can-kicking. We were wondering about that given that the MJO phases forecast was not jiving with the H5 look.

12z gfs and GGEM both are close with this idea

Reach out to @dendriteand he can change it

As a longwave pattern no, but with the right shortwave timing and the blocking over the pole, it’s possible.

GEFS and EPS both have several nice features by Xmas week: -EPO, ridge bridge across the pole with -AO, -east NAO. But both have a pig of a -PNA also. We need that EPO ridge to move east a bit to kick that trough at least out into the Plains.

Since there’s nothing happening for at least a week… If you squint, you can maybe envision an overrunning/southwest flow event around D8-12 (next weekend). TPV rotates down through central and eastern Canada perhaps while pieces of that Baja Low may eject out into the southern Plains. What we need is for the TPV to provide just enough cold air and suppression and for only a modest piece of the Baja low to eject so it’s not too strong and pumps the SE ridge again. It’s a long shot…we don’t usually score at the start of a pattern transition, but it’s the only thing I see in the next 15 days.

Coldest this season here as well, but still only 25F.

DCA hasn’t been below 22F in like 3 years? So yeah, give me the vodka cold so it can sneak down to 21F in an intrahour!

Four T’s so far: 11/27, 11/29, 11/30, 12/8

Saw a tweet earlier this week. Every major station east of the MS river (and probably most west of it too) is BN on snowfall. Lake effect zones aren’t too far behind yet I think. I believe Buffalo and Syracuse were like 5-6” behind. Erie was 10” or so.

Micro-pixie dust in Columbia. Biggest December snow of the 2021-2022 season!

Damn, who could have predicted an I-95 snow hole and the NW crew to cash in big time??!! I’ll have to remember that for next time!
