Really? Does the rain stay mainly on the plain? @MN Transplant bad joke there good sir

Near perfect pass for the h5 for us to get mega CCB'd... @MillvilleWx was right on it at the 90 hr mark on the 06z EURO h5

Yet the best guess precip type on all of the soundings at DCA at hr 90 is.... snow. The entire column is fine till the last 50 meters

Better check with @PivotPoint on this first

Tasty

Just checked that and wow... indeed you are right. That was weenie porn indeed

Damn... really wish the 06z EURO went out one more frame... looked like the CCB was going to be going nicely for us

Soundings suggest otherwise at DCA and along i95 corridor. DCA at 96 is snow. But we'll just have to agree to disagree

6z gfs sucked for dc. Way to close for comfort even into loudoun huh? You get 20" on the 06z GFS... stop playin

disagree on the i95 corridor... 06z GFS was just right lol. It kept the area along and west in the snow the entire (well most) of the time. 06z GEFS support that.

06z RGEM at 84 looks good to me as well

Thanks for taking your time to post in our thread... esp with your detailed posts. Its greatly appreciated

@MillvilleWx would probably be better able to explain, but I believe so yes. Looking at the 6 hour snowfall amounts, 06z GFS is printing out 2" per hour rates (and higher in some spots) due to the extreme frontogenisis. I think this is causing the algorithm to show mix instead of the very heavy snow.

Rates are silly in the CCB at 96...

06z GFS is a mauling for i95 corridor and west

lol 0.2 at DCA... nice try

great disco from LWX this morning

URGENT - WINTER WEATHER MESSAGE National Weather Service Baltimore MD/Washington DC 352 AM EST Sun Dec 13 2020 VAZ503-WVZ501-505-131700- /O.NEW.KLWX.WS.A.0001.201214T0300Z-201214T1800Z/ Western Highland-Western Grant-Western Pendleton- 352 AM EST Sun Dec 13 2020 ...WINTER STORM WATCH IN EFFECT FROM THIS EVENING THROUGH MONDAY AFTERNOON... * WHAT...Heavy snow possible. Total snow accumulations of 6 inches or greater are possible. * WHERE...In Virginia, Western Highland County. In West Virginia, Western Grant and Western Pendleton Counties. * WHEN...From late this evening through early Monday afternoon. * IMPACTS...Travel could be very difficult. The hazardous conditions could impact the Monday morning commute. * ADDITIONAL DETAILS...The highest snow totals are expected on the ridges above 3000 feet elevation.

We may have to wait till Monday IMO when the h5 pieces/SLP for the Monday "event" finally moves into the NE/Canadian Maritimes before we get a better idea of where the players for our snow will be on Wednesday. As griteater pointed out... the 50/50 low positioning seems to be crucial to us down here. ETA: seems like you ninja'd me above... my bad

guess we'll see in about an hour whether or not the EPS backs up the OP or is a bit further east and leaves the OP on an island by itself

Euro isnt good

UKIE 6-12 for most i95 and west... @mappy jackpot (north central MD into NE MD 12"+)

Pivotal Weather will have it in the next 10 minutes... already out to 36

His 18z ensembles were nice for us... I expect him to show some forgiveness at 00z
