2/22-23 "There's no way..." Storm Part 2

[Maestrobjwa]

Alright good people! So...given the trends I officially one eye brow up. Will there be delicious snow egg on my face? (The only kind of egg I like). Or will it be white rain? Is the Euro caving?  IVT or full blown coastal? Find out in this next riveting movement of this weather symphony!

Note: Please follow the mods requests and stay on topic...and avoid bickering! We don't need that dissonance in the orchestra 

[yoda]

@WxUSAF or any mod to pin and use this thread as the new one. 

Let's all focus in more on weather/modelogy in here and keep the banter in the respective thread.  If you see posts disappearing... you should know why 

Edit - thanks @mappy

That looks pretty reasonable to me although maybe questionable for Mt Holly’s area 

[Eskimo Joe]

Mt. Holly hoisting watches. The language definitely signals a moderate to high impact event:

Latest Srefs. A bit of a jog south, but not by much.

[WEATHER53]

It may be temps that become critical as we have focused on neg tilt  and other factors.  33/34 from 11-4pm  won’t allow significant accumulation around DC unless heavy.  0.5-.75 ph rates won’t achieve equal accumulation. 1”ph rates would allow about 0.25- 0.5” ph accumulation . 32/33 improves and 31/32 is very good

There is a lot of bust potential inside the beltway if rates are bad. I'd probably undercut guidance below 300'

We know the deal.  Dynamic cooling doesn't work here. we need a proper airmass

What? 

If you have the rates you will get dynamic cooling. Location has nothing to do with it. 

Getting the rates could be the issue depending on what plays out. If you get under a coastal CCB you're going to get nuked with snow heavy enough that it's gonna accumulate whether you like it or not. The question is whether or not it will get west enough and how strong it will be.

[grhqofb5]

I don’t mean to be a Debbie downer here. But (in strictly Laymans terms)isn’t there a good chance that this is going to end up being a bunch of rain because the temperature is not supposed to fall below freezing during the entire event? Having a hard time buying this one.

[yoda]

Thats a weird looking watch contour... but i guess they are going elevation for now

[weathercoins]

Yeah pretty surprised they did not put up a watch regionwide 

[Nomz]

Baltimore officially under the gun.
