This works both ways. The latest snow map does not line up with their watches and warnings, so i think there was just a glitch...the snow map is not changed from last night.

That bullseye of colder h85 temps directly over me caught my eye Cold air stuck in the Valley. Blue ridge is our friend in this instance. But with the track being shown i will be surprised if we don't mix some even here. Link to comment Share on other sites More sharing options...

Given the trends with this thing, my bar in Germantown is 4". Some of our forum's northern spots could end up with fat ice sandwich -- 6 or so inches of snow, a thick layer of sleet congealed by some freezing rain, then a few inches of powder on top. Enjoy!

psuhoffman Posted December 15, 2020 Share Posted December 15, 2020 @mappy 6z euro was good if you take it in a vacuum but it again nudged everything NW as every run has for 2 days and even up here we are out of any wiggle room. Any further adjustment and we will lose both the WAA front thump but especially any back end as the best forcing for that keeps shifting north. If the trend stops right now we are ok but any continued west shifts of the track today and we are in trouble even up here. Link to comment Share on other sites More sharing options...
Kmlwx Posted December 15, 2020 Share Posted December 15, 2020 Well...when I walked out to my car a little while ago (Arundel Mills area). All my windows were frozen over, a bottle of water inside had frozen and the washer fluid froze on contact. I'm just going to take the weenie approach and assume that I have a local cold dome that will make me invincible to the changeover. Might head back to my parent's place in Colesville to watch this one. Probably similar totals overall... 1 Link to comment Share on other sites More sharing options...
weathergeek Posted December 15, 2020 Share Posted December 15, 2020 That map is nuts. I live in Glen Burnie so I'll be chasing to the NW side of my neighborhood for a few extra inchesMy point and click forecast for 22207 (cherrydale) is up to 3 inches with heavy rain mixed in during duration. 3 miles toward Falls Church is up to 7 inches, with possible ice . 1 Link to comment Share on other sites More sharing options...

If the trend stops right now we are ok but any continued west shifts of the track today and we are in trouble even up here. Haven’t seen 6z euro, but took a quick look at other guidance. For MBY, it looks to all come down to the WAA thump. Thankfully, it looks pretty good on the 0z euro and meso guidance. But after that, it’s a sleet/rain mess and the CCB looks north of me. Maybe a finger of it sweeps through and gives me another dusting-2” tops, but that’s it. Pretty bleak frankly compared to 36hrs ago. If it wasn’t for that high pressure and confluence, this would be 100% rain for almost everyone with that surface low track. Link to comment Share on other sites More sharing options...

Kleimax Posted December 15, 2020 Share Posted December 15, 2020 The NWS has 12-18 inches for me in Owings mills in the WSW... not seeing how that’s possible. Even the updated snowfall map of 8-12 doesn’t seem likely. Link to comment Share on other sites More sharing options...

If your windshield washer fluid froze at 30 degrees (or even 0 degrees, for that matter), it's not windshield washer fluid. 1 1 Link to comment Share on other sites More sharing options...

caviman2201 Posted December 15, 2020 Share Posted December 15, 2020 In all seriousness though if there ever was a storm for novice chasers, this is it. If this crazy gradient verifies, those of us in the coastal plain who have never chased have a rare opportunity to chase from cold rain to a foot of snow and be back before our boss notices we left. 2 Link to comment Share on other sites More sharing options...

I agree. Usually I use the orange Rain-X stuff and it's great. This is stuff the dealer put in. It's crap. Link to comment Share on other sites More sharing options...
North Balti Zen Posted December 15, 2020 Share Posted December 15, 2020 If this NAM is right Emmitsburg is not far enough for me to go. May just cancel and stay home, chasing to central PA not an option technically during PA's covid restrictions. 1 Link to comment Share on other sites More sharing options...

Warm Nose Posted December 15, 2020 Share Posted December 15, 2020 This is a cold rain 'near miss' and/or sleet fest for most here. Fun while it lasted ... it follows a similar pattern, we should be used to it by now. Link to comment Share on other sites More sharing options...

Yeah I'd be tempted to do my 33-mile mini chase to Greenbrier Park off I-70 but man even there is looking dodgy now. Link to comment Share on other sites More sharing options...
