Feels like an event that starts as rain or a rain/snow mix and transitions to snow just before precip shuts off leaving like maybe a slushy half inch on grassy areas. Would love to be wrong and I'm definitely hoping for precip to start as early as possible. Expand I agree strongly. I think the only places that have a shot at 1" and/or slushy roads are out near frederick/Hagerstown down to Winchester, Front Royal and further SW Link to comment Share on other sites More sharing options...

Expand the cold air is fairly deep so although surface temps are not great the dews and 850s are solid to this untrained eye. it should be solid snow tv and reaffirm why we love this hobby. we will be pinging you for obs as you should be part of the first wave. 2 Link to comment Share on other sites More sharing options...

Expand Yeah you would need to look at temp profiles from the surface on up. If that warm layer is shallow and near the ground, and with dewpoints low as Wes said, then those temps can fall like a rock. 2 Link to comment Share on other sites More sharing options...

Expand Agreed, just would rather not waste precip getting temps to cooperate here along 95, but where we are headed, any snow is great. This has a feel of a rush hour WWA for the 95 corridor though too, out your way should be a decen 1-3 type WWA event. Link to comment Share on other sites More sharing options...
nj2va Posted January 6, 2020 Share Posted January 6, 2020 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! Link to comment Share on other sites More sharing options...

Ji Posted January 6, 2020 Share Posted January 6, 2020 2001-02 had one winter storm(i think it was 3 inches) in early January and we never saw cold or snow again that winter.

Bob Chill Posted January 6, 2020 Share Posted January 6, 2020 Only way my yard can eclipse an inch is if it's hot and heavy. like .2-.3 in 2-3 hours. There seems to be a legit chance for that to happen so maybe it's not crazy to expect 1" in the closer burbs. Link to comment Share on other sites More sharing options...
clskinsfan Posted January 6, 2020 Share Posted January 6, 2020 These are the RGEM temps at the onset of precip. Those of us in the Shenendoah Valley are looking really good for this one IMO. Most of the models are starting to juice up a little bit as we get closer as well. Someone is gonna grab 3+ inches in the 81 corridor: 1 Link to comment Share on other sites More sharing options...

Bob Chill Posted January 6, 2020 Share Posted January 6, 2020 Still a half decent sounding at onset of the heavier QPF along and west of I95. Consistent with the potential for rippage even if brief. ETA: here's the sim radar panel that coincides with the sounding. Legit rippage going on in places (like the most important place...my yard) 1 1 Link to comment Share on other sites More sharing options...
