A big shift like that in the nearer term makes me anxious... dunno that I like its downstream implications here. Result of that phase is the 957 low near Newfoundland. TPV looks weaker and further north. Helps amp the SER more. That wave out west isn't helping either.View attachment 58239

I think it really just boils down to whether or not those two waves in the pacific phase. If they do, we get a more -PNA, and stronger LR WAR. We also get a less negative EPO because we don’t have that wave to help push it north.

Southern Christmas storm a decade ago was a Baja wave that we tracked 5-7 days out. Never wavered. Cross your fingers and clench your buttcheeks. A chance is all you can ask for.

It had a @Rain Cold guarantee! But it was looking a lot more suppressed than it ended up being. There was a big NW shift in the last 24-48 hours that put places like Greensboro and even the foothills and mountains in the game. And overrunning overperformed.

I think the NW shift also allowed it to nail DC with 6-12”, as DC basically got feet of snow on the regular in that time period.

What did January 17-18 2018 look like at H5 ? @Ollie Williams
Pattern here isn’t far off

I literally plotted it today, and I’ll share it tomorrow, but the H5 look wave very different. The wave was just barely holding onto the north from being cut off over AL/MS. There was a big +PNA and ridge over central Canada to the NW, and a little ridge the the NE.

CR had the magic whammy fingers for that one. I wonder if he still has another in him? Might be too old now, lol....maybe they have some blue pills to help enhance weather prediction prowess :) He's already a legend in Ga. A twofer for Xmas day storms would hang his weather gear in the rafters. Come on, CR, this one has potential. Get a secondary system to start up with that gulf tap, lag behind so the cold air gets in first. It could happen, with some whammy fingers .

That storm really was a Christmas miracle, maybe Santa will give us another one after all the crap we’ve endured this decade.
 
And the long-term implications of those changes for the close call on the 18z are what I suspected. Southern stream looks barely changed and western ridge improved a bit, but that nice 50/50 low (and mega high pressure) noped out. TPV didn't stick around the same way. Still far out there, subject to a lot of changes.

What the GFS spits out for this (another flizzard, with a tilt just a bit too far east) is better than I thought it would be actually. Just not as promising of a setup as last run was showing.
