understudyhero Posted January 22 Share Posted January 22 What does sleet look like at 20 degrees like I can't imagine it. Does it just instantly crust up the snow on the ground already? Link to comment Share on other sites More sharing options...

MillvilleWx Posted January 22 Share Posted January 22 1 minute ago, Eskimo Joe said: That was an epic storm. 24" of snow in Damascus, 5" in Takoma Park. We had nearly dry roads in southern Montgomery County, while upcounty it was snowing hard. Storm was wild. Temps much colder this go around too. Should be an interesting night Saturday into Sunday morning. Link to comment Share on other sites More sharing options...

CAPE Posted January 22 Share Posted January 22 3 minutes ago, JenkinsJinkies said: There's also the NW trend though. The developing coastal low is tucked on the Euro and CMC. GFS has a damn near perfect track to keep almost everyone frozen. Be great if it has the right idea, but its kind of alone, and it is the GFS. 2 Link to comment Share on other sites More sharing options...

Cobalt Posted January 22 Share Posted January 22 2 minutes ago, MillvilleWx said: Some was, but Mt Airy actually got close to close to 20” from the front end thump. There was a band that setup over there area down to Clarksburg that absolutely crushed them. Never forecast until the last minute. That can happen with these setups. Never know!! Many of the analog events had surprise winners from the front end thump. Folks brought up Feb 21, 2015 as such an instance. Feb 16, 2016 is another good one, that had brutal cold leading in. 1 Link to comment Share on other sites More sharing options...

RevWarReenactor Posted January 22 Share Posted January 22 9 minutes ago, SnowGolfBro said: My biggest concern is we keep trending northwest and end up with disaster of an ice storm. Like is being progged to our south. If widespread power outages hit the major cities and suburbs, we could have millions without power heading into an arctic blast. We are a little over 2 days out. This isn't a week away. If things trend that bad in that short of a time period, that would be a failure on the models of monumental proportions. Its unlikely.

Hopefully a foot on the ground before the inevitable flip to sleet i have to feel like you guys near the MD/PA border are in pretty good shape. 1 Link to comment Share on other sites More sharing options...
NorthArlington101 Posted January 22 Share Posted January 22 I feel like the energy in here is shifting the wrong way for pretty much no reason? If you are holding onto the GFS as anything but a longshot perfect outcome, you're gonna have a bad time. But everything else pretty much tells the same story: 5-8"+ for most people in the metros on the thump then we go to sleetmaggedon. Usual folks out west probably climb above 1'. It's not gonna rain, at least. Gonna be wicked in it's own way. 3 Link to comment Share on other sites More sharing options...

CAPE Posted January 22 Share Posted January 22 I question the amount of freezing rain the Euro is depicting for the DC area up towards Baltimore. Something seems off with that. Probably some of that is sleet. 1 Link to comment Share on other sites More sharing options...

I envision this storm as a reverse 2011 Commutageddon, occurring near the 15th anniversary, with heavy snow at the onset followed by prolonged sleet — a different evolution, but potentially similar societal impacts.
