I'm staying put in my office in Rosslyn vs working from home this afternoon in S. Arlington (south of the fall line)....could make a difference of 0.25"

stop talking....you're generating too much extra warm air

It was 52 yesterday so I doubt snow will stick today.

Looks like we’re in for a day of meh, bust, hrrrrrrrrr, and omg I hate living here in DC where it NEVER snows.

Clouding up ahead of sunrise here. Hopefully can keep it colder by a degree or so...in marginal setups every bit counts along/East of 95.

Loudoun closed which means PWC isn’t far behind.

First legit snow of the season here locally, I’m pumped; sticking with 1-2” here with amounts closer to an inch than two. We’ll hit the low 40s before precip kicks in and we wet bulb. I’m sure there will be lots of complaining posts but if you’re along/East of 95, set your expectations now to see a rain/snow mix at onset. Won’t be surprised a favored spot NW hits 5” but it’ll be very localized. ETA: got to a low of 31 even inside the Beltway south of the fall line so that’s encouraging.

UHI hell. I just dipped to 36 here in south Arlington.

Down to 38/24 here.

^^ I’d go with 2 10” storms in a month.

Might is the key there

Feels great to track an event again. Seems like Bristow may rescind his reservation request.

Always best when LWX plays catch up.

While I agree that positive snow depth change is useful to compare with 10:1 maps, I agree with WxUSAF’s comment earlier that it may be a little underdone. It’s not like its 36 with light precip falling over 7 hours. A middle ground between 10:1 & snow depth change is probably a little more realistic.

18z Euro and 00z NAM both get DC about 0.45” QPF...heavy rates will easily overcome surface temps. And just above the surface is cold so the rates will bring down those colder temperates to the surface too. #weenie

ha, I thought the same thing when I first read it. I wonder what the threshold for heavy for them is....is under 30” during the afternoon just be snow showers??

I’m in the heat valley of South Arlington where its 44 degrees. Though there’s a big range of temps on the weather stations around me - from 37 to 45 so who knows

44/21 currently. High of 54.

Waaaaaay out of range.

Snow on Tuesday followed by 70 on Saturday is how we do winter in the mid-Atlantic.

Out around 7p

Really happy to read the changes in the storm thread about salting by MDOT. VDOT needs to change that asap too. Terrible impacts on our waterways and a waste of money, too.

What will help is the DP in the upper 20s. I don't even care about street accumulations...I'm happy with a heavy burst of snow and some grass accumulations.

This is actually looking better than what I expected even yesterday...I'm thinking 1" is a good call for here. Obviously west of 95 looks best given the temp profile. I'm all in!
