A lot of this stuff is also on the margins...like even the paper Tip linked was something like a 2% change in the speed for every 1C of warming. So you have a 204 knot jet streak instead of 200 knots....

Who is this dude from the Nintendo game? The polar bear dude dressed as a greaser from the 1950s who threw boulders at you.

The end of the 06z GEFS looked pretty nice...I don't trust anything beyond about D9-10 though right now because the swings and inconsistency have been remarkable compared to the usual D11-16 variance.
-
Didn't realize it, but BOS officially got 0.2" yesterday....so that's first measurable for them. Still think PVD and BDL are waiting on first measurable. ORH is sitting at 3.0" from November.
-
How is that different from any of the other 80-90% of years where snow hasn't fallen yet in early December there?
-
Hmmm not ringing a bell. Was it in December or earlier in the autumn? The only cutter I recall in Dec 93 was 12/21/93…it was more of a HV runner but we got into the warm sector and got windy. I don’t remember massive winds here but elsewhere in SNE wouldn’t have surprised me.
-
I’ll imbibe in a legit HWW event but they are generally so rare around here in the interior. The 12/17/00 one though was crazy. I think we gusted 65-70 and lost power for a few hours.
-
Xmas Eve 1996 was a good one too…ruined the White Xmas chances here but it was very windy. Not technically an so southerly screamer, but we had an epic wind nor Easter (esp on the coast) in Dec 1994 on Xmas Eve into Xmas day. It was subtropical iirc…no cold anywhere so it was rain even into the mountains of NNE despite a benchmark track.
-
12/17/00 was pretty epic…ironically that was a frigid month too but we had that one big screamer in the middle of it and it didn’t disappoint. Trying to remember the early 90s one being reference but can’t really. Though I tended to to ignore cutters back then so I don’t remember them as well as snow events.
-
I mean, just look at the EPO region…went from deep blue to orange in 48 hours. Horrific continuity…we wouldn’t be surprised on an OP run but for an ensemble mean to do that is notable. Shows how clueless guidance is right now.
-
Our batting average on these is like late-career Chris Davis levels. For every “hit” there’s like 10 whiffs.
-
He posted 60mph at 5k feet…lol But yeah, if it actually gets to 90+ knots, then there’s at least some potential to mix down 50+ at sfc, though even usually that isn’t enough because of inversion. edit: I reread his tweet…looks like he was just coloring minimum of 60 at 850 and not saying that was the cap…not sure why we’d even care about values that low. You’d prob want to start at 80+.
-
50 knot winds at 850mb in the winter on southerly flow…can you get any more mundane for a high wind threat?
-
I think they are having trouble with the transition period. There’s a strong MJO wave moving through phases 5-6-7 over the next 10-12 days but that is probably conflicting a bit with the low frequency stuff closer to the dateline. So it’s destructive interference if that is indeed the case. I think models are confident in a good period once we’re out of that destructive interference period which is why very late December into January has consistently looked good.
-
The ensembles are pretty clueless beyond D10 right now. Check out this animation for the last 48 hours on the EPS…12z on the 4th, 12z yesterday and 12z today….all 3 of these are valid Dec 18th 00z
-
Been persistent down there
-
Is BOX radar down? Nice timing.
-
Yeah I feel like you could extend it from 1992-2015. While 2018 and 2021 were good, those were clearly in a different paradigm where the crazy exciting stuff was becoming far less frequent. I mean, even in the 1980s we had the occasional bomb…they were just far outweighed by the torturous regimes of all shapes and sizes. For some, it’s 1993-2015…Scooter and the CT Valley would beg to differ about December 1992 being euphoric.
-
@CoastalWx Todays weeklies show that bit of increased split flow we were talking about earlier for week 2…hopefully this trend keeps up and maybe we can avoid a pre-Xmas grinch
-
The weeklies sort of showed that happening when you break it down into the sub-week level. Between roughly the 20th and 25th it really tries to spike the PNA via Aleutian low intensification even if the absolute strength of the low isn’t super high yet. The fact that it tries to replace Aleutian ridging is enough.
-
EPS has that window of opportunity similar to what the GFS showed…more defined on todays 12z run.
-
You need to fire up a blog post for the southerly wind threat.
-
2016-17 was a pretty solid winter up there too not long before he moved there…had a couple of latitude storms. It’s like as soon as he moved there l, they turned into the CT river valley.
-
Then followed by an ‘07-08 extreme latitude gradient winter where he gets almost double the pike region.
