Berk had a graphic earlier on Twitter showing the baroclinic leaf

46 degrees here Baltimore County but only 32.5 in parts if Carroll

Pictures coming out of NYC this evening are awful. They were completely unprepared for the snow. They're having their own commuteageddon. Judging by some of the photos, motorists may be stuck on the highway for hours.

Yeah it's low for the mountains above 2000 feet for sure, but it's above average for the Shenandoah Valley. I guess it's average to slightly above for other areas---above for Frederick MD--and maybe slightly below for your area in Carroll. I have to think Topper wasn't really making an educated guess when it came to Western Maryland and Allegheny Mountains.

Berk posted lwx's regional snowfall average map which can be found here: https://justinweather.com/2017/11/18/maryland-winters-snowfall-by-region-and-baltimore-records/ t's decent.

I would think both places would be significantly better. As you get into northern Baltimore County or into Carroll those places would be comparable and maybe better than Hgr or Thurmont. If you have elevation near the Catoctins that obviously helps even more. I lived in Winchester for years and Hagerstown "on balance" did much better but Winchester was better than Baltimore.

For you Maryland winter weather experts, I moved from Columbia to Owings Mills in September after spending about a year and a half in Columbia. (Lived most of my life in Winchester, VA.) How does the average/median snowfall compare between Columbia and Owings Mills? Believe my elevation is about 600 feet.

I'm thinking the bulk of the snow, even out there will be overnight through noon Wednesday. If that's heavy snow, it's easily 8-12 inches

I lucked out on this storm and am working from Winchester this week.

Cranky weather guy has been tweeting about the northwest turn of the low. Seems like precip shield won't expand much.

Light snow in Columbia. Tops of cars are covered, looks like grass too.

A spotter reported an inch in Stephens City

Yep, I lived about 10 miles west of Winchester and woke up to about 12-14 inches of snow but roads were black top by early afternoon

Yeah, 2009 was jackpotting central va in the lead up

Presidents Day 03 was talked about well in advance also
