Misc 2021-22 Fall/Winter Whamby Thread

oh, if rgem had a big snowstorm and nam didn't you can bet the nam would be tossed but the rgem not. o_O
I’ve found the best approach to get an idea of what’s going on is to visit multiple forums . Right now my go to are here , mid Atlantic americanwx and nyc American wx. Each paint a different picture . I do the same for long range pattern . Here and wxdisco ( old accu weather forum )

That's literally the three forums I go on as well lol.
 
I joke in jest, We know they aren't getting a foot of snow. 1. it's not going to be 10:1 ratios, and 2. only half of what falls will linger. Can't get efficient accumulation when it's 33 and 34 degrees.
But it’s not 33 and 34 degrees the entire time. You keep saying this but we’re dealing with a column that’s crashing and already cold antecedent conditions.

It was 38 degrees when it started snowing on both 12/18 and 1/23/03. You are not dealing in reality.

Yeah , heavy wet snow . Column crashing is fun.
 
6Z GFS should have more buzz! It was a great run! Winter’s not over! Mega analfrontal incoming for our torchy February D8B7B438-AB58-4E57-B754-1D329C10EC7A.pngA480829D-273F-4F56-87EB-FA55CB4CA899.png79B1815A-57CA-4069-A33E-C4AD7954A4FA.png
 
^ you can see in that last image something all over CAE. Looks like a video I watched last night. All imma say about that.

I never stated the entire event, but there will be a several hour window of snow (maybe more) @ or above 32 degrees. You will not get efficient accumulations.

This whole column crashing is 100% rate driven, so if the rates aren't as strong as depicted on the NAM, then you can be even warmer.

And since I was referring to Bern in my first post, here's the GFS sounding for Bern.

And here's Durham. GFS doesn't show below freezing till after precip is moving out.

Both situations would verify as 32/SN for both locations. It’s not ideal, I’ll agree, but it’s also not going to snow for hours at 34 like the models show, either. Models often keep BL temps too high in such situations, when in reality 2m temps almost always drop to freezing.
 
I'm not getting any reacts on my rgem vs nam gif. i should stop i guess.

?

You know me man...most of the time, I'm going to ride out with you and suit up with the cold first jersey. In this case, if we get light precip, honestly, who cares if it's rain or snow. It's going to come down in the middle of the night and probably won't amount to more than a dusting. But if we get rapid cyclogenesis off the coast, there will be plenty of precipitation and plenty of that will be snow. It won't be efficient at first, but it'll get there.
