It’s an interesting argument on Twitter and I’m not sure how if this is really a disagreement or just confusion. But it seems 12z eps was a pretty huge outlier from a long trend. So either way I’d wait for some confirmation before jumping off a cliff.
That plus a SSW will favor a trough east of the Rockies at some time lag after it happens. So if it happens around the 7th, the SSW would start helping that pattern around the 15-20th.
Solid ensemble agreement for the period around the 6/7th. Still a ways to go. I also like seeing signs that any “mild/relax” period will be pretty short lived. Can already see off/on hints of the trough undercutting the NAO and also reestablishing an aleutian low.
Yeah, freezing level is like 950mb in that deform band. It’s low, but also not right at the surface. So I think it would be pouring slush bombs at 34 if it happened like that. But it “should” be a 30-32F pasting.
I think I agree that there would be at least some snow in that deform band on the back with that look. But the torched boundary layer at that point is pretty alarming and discouraging.
Don’t care that much, but I seem to be one of the very few people who can’t click on post reactions to see who reacted. Phone and computer, neither works for me.
And GFS/GEFS has a notable strong vortex bias, so extra encouraging to see it onboard as well. Assuming this holds and we get an official SSW around the 3rd, question becomes how fast it impacts the troposphere on our side of the planet.
