24+ would be so amazing in DC. Loving the radar/sat presentation down south. Keep that S coming guys!

Looks reasonable to me. I might expand that 24+ out into elevated areas a little further. But thats just because I live there

DT is buying the GFS and buying the idea that precip. shuts off at 06Z Sunday.

Sorry, have been busy most of day and trying to catch up on the major threads here....is there incoming data supporting a later than 06z Sunday wind-down in D.C. region?

That's eerily early if Feds close early.

This is probably as extreme a forecast as we will ever see for central Va

[Eskimo Joe]

Folks...snowfall measurements with this storm will be very important.  FEMA declares disasters based off the amount of snow each county has received and then compares it to the emergency response expenses.  Measure twice, report once.

[clskinsfan]

Look at post 44 above. The precip shield has doubled in size over the past 3 hours. This is gonna be a monster.

They even said on the radio show measure a ton of times - the drifting is going to make it very very difficult. Take like 15 measurements and see what shows up the most. 

[84 Hour NAM]

This stuff is getting in here before 4pm tomorrow I can guarantee you that. It's already in southwest VA

I'm planning on putting snow boards with marker poles. I'll have to double it for the white monster. She's one bad a&* looking storm. Absolutely stunning show of force. Sends chill up my spine.

[Mikethemanatee]

So does the fact that precipitation is already in SW VA mean anything?

I was wondering the same thing. Is the timing correct or is it coming in sooner? My sister is going to be moving her son in to U of MD tomorrow.

But they are allowing new students to move in tomorrow
