Gfs at 24 hrs is def colder for sw va extending up the 81 corridor. Has a pocket of 0c 850s and the moisture is more significant on this run. Could get interesting for the guys along 81. It may be trying to compensate for the lift that we usually get off the mountains. Could have just been a blip tho because at 27 it is gone.

Sure makes you hesitate to go with the NAM.

I haven't looked at soundings yet. Maybe it's closer than the maps make it look? I've been next storm focused so I really didn't follow model progression till today.

Forecaster's Discussion

" .SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY/...

FOCUS OF FRI NIGHT-SAT WILL BE A DEVELOPING COASTAL PLAIN LOW AS
IT CROSSES FROM ERN NC TO OFF THE SHORE AT THE NC/VA BORDER. THIS
TRACK IS VERY FAVORABLE FOR PRECIPITATION ACROSS THE AREA.
HOWEVER...THE PRESENCE OF THE NRN STREAM TROUGH NORTH OF THE
GREAT LAKES IS LIMITING COLD AIR. THE COOL AIR THAT IS THERE ALONG
WITH DYNAMICAL COOLING WILL BRING ADVISORY LVL SNOW/WINTRY MIX TO
AREAS WEST OF THE I-95 CORRIDOR FRI NIGHT-SAT.

DID HOURLY TEMPERATURES TO ACCOUNT FOR WARM AIR CROSSING SRN MD
FRIDAY NIGHT WITH WARMING THROUGH THE NIGHT THERE. SHOULD SEE
FRONTOGENESIS WITH SLIGHT COOLING FOR CNTRL/NERN MD. THIS IS WHERE
A BAND/TROWAL WOULD SET UP WHICH COULD UP SNOW TOTALS ALONG AND
NORTH OF A LINE FROM DC TO BALTIMORE SHOULD DYNAMICAL COOLING BE
STRONG ENOUGH.

WRAP AROUND PRECIP LOOKS TO CHANGE TO SNOW SATURDAY...BUT A
WINTRY MIX COULD HOLD ON THROUGH MOST OF THE MORNING."

Hope I'm wrong but would say this looks a lot like all rain 43-47 F with just a slushy mix near the end for the I-95 major population areas, of course some 3-6 inch accumulations possible at good elevations north and west. But the storm does one good thing -- it forces stronger high pressure to linger around for the later storm next week and that one looks fairly promising for you. Will think about it and post in that thread too.

I really don't see how we get a thump like the NAM suggests. It's not like we start with -5c 850s and then quickly rise to 0C. They are 1c to begin with and we are praying for wetbulbing and dynamic cooling.

hope baby...it springs eternal in these parts

NAM gives me 11.08mm of all snow for the first 5 hours (I checked hourly soundings and I'm good thru 29 hrs)

at 30 hours, it has switched and 2.85mm fall the 30th hour, so some of that is still snow....say 1mm, so IF it's right, I'm looking at 12mm of wet snow, or 4"+
