I’m genuinely concerned now for your area. This could be really ugly. I know you know the at anytime temp is <28° during ZR, accretion processes are maximized. <25° is usually when you see the greatest ice storms occur and it could very well be that way over your area back into VA.

It’s not hyperbole when I say this will be one of the extreme cold plunges we have seen since 2014 in these parts. With snow and ice on the ground will make travel issues for days on end. I’m bullish and think some places will see 18-22” of snow somewhere out of this, it’s just a matter of where. I expect it to occur in Northern MD by your hood across the M/D. Someone is going to get shelled.

I like Louis as a person and as a winter mind, but I think he needs to lay off the hard liquor. There isn’t a single model that is that route and there won’t be. Not sure why he said that. Need a full phase over the Four Corners for that.

Looking at everything, I think some here are really hung up on the sleet mixing and not enough on the absolute drubbing that WAA pattern is going to bring for the thump up front. This is a setup that can rival the Feb 2014 thump in places. The initial 4hrs when snow becomes heavy too will be big beautiful dendrites in the stronger bands. 1-2”/hr rates likely with some bands >2”/hr considering the strength and depth of the FGEN and DGZ, respectively. If you can remember 2014, there was 2’ of snow in Mt. Airy and not a single model showed that until it basically on top of us. Use climo, know your area for who usually hangs on to snow the longest. This will be a crazy beatdown prior to any flip. Lowlands will mix, metros will mix, eastern shore will mix, and mix will likely make it to I-70….it is what it is. It’s the nature of an upper pattern closing off west of where we want it. However, the snow will come in hot and heavy and last for a while to bring in some great totals, the biggest of which some have seen in a decade. Thermals will be situated as we get into Friday and the NAM Nest comes into line. That’s the model I want to see. That piece of guidance usually sucks, but it does do well at showing the thermal progression while sucking otherwise. It’s gonna snow y’all!! As for Southwest VA, it sucks this shift happened so abruptly. I wasn’t anticipating THIS much of a shift, but there will be some heavy heavy snow upfront before driving sleet. It will be a high impact scenario for so many. And the cold afterwards is NO JOKE!! This isn’t going anywhere.

It’s wild out there. A completely different world. I want the front end thump to be like what the models show tonight. That will produce some insane dendrites and walls of white for a while.

You know who is going to absolutely clean up on this setup? @jonjon I’ve been noticing the wind pattern with this one out there. Davis might hit 30” with this one.

I would wait for sure, but it could be pretty difficult on Monday morning. Still some time to keep an eye on things.

That front end thump is a straight ass kicking before any flip. 1-1.4” of precip, all snow before any flip to IP on the EC for any area west of the Bay. The 700mb FGEN are textbook on Pivotal as the WAA pattern moves in. A solid 10-18” falls before sleet comes into the picture, and the storm actually ends as snow to cap off any sleet. This is a really strong WAA pattern being depicted now with the phasing depiction. It will come in really hot and heavy like a wall. Still time for changes. This system can only climb so far north with the current upper level pattern as progged. QPF prior to flip Snow before any flip 700mb FGEN

This makes more sense in a physics sense and the post by Tripol has a lot of merit. This is not a pattern where a low can drive hard to western PA and should in theory struggle to get to WV. This should be more of a primary to transfer from eastern TN/KY to off the Carolina coast. That’s what the AIFS is showing and makes more sense synoptically.

Man, it could be a beautiful sight around here if the CMC/UKMet come to fruition. I am actually on vacation and willing to travel if need be to get into the jackpot. Anyone care to host a meteorologist? I can cook really well, clean up after myself, and I’m a big fan of geeking out over snowstorms

This was the key. Idc what kind of cold air intrusion you have, a low onto Charleston, WV is gonna cause mix issues. If we get the primary closer to Knoxville area, that probably perfect. I would even work with Eastern KY. Just can’t get it north of there or there will be mixing.

It does, but it lowers the accum amounts per panel to account for the lower overall ratio of the sleet. It was 11” of snow before the flip for DC. Was looking earlier.

1043mb reinforcing HP over Quebec. I might shed a tear

Man, that run was great. I still can’t get over Nashville at 15+ inches of snow either being forecast. Their record was set in the 1890’s at 17.4” for a single storm. This is gearing up to be a potentially special storm for a large part of the country.

I haven’t looked too closely at that, but I would bet some slant-wise instability will be found somewhere in this. Bob showed a point sounding with a bit of MLCAPE which should promote a better opportunity for some thunder prospects. Considering the sounding Bob had, I would suspect the best chance would be across the Western Carolina’s up into Central VA within the primary 7H Frontgen pattern that materializes late-Sat PM into Sunday AM.
