Few pictures from the yard and neighborhood

My snowboard and car have lost snow since noon, but there’s clearly more snow on everything. Kids patio table has almost 2.5”. Grill has 2”. Both look relatively unaffected by wind.

Agree. Still, this would have been widespread 2-6” or more if it had fallen at night. You’re west of me and BWI and it made a notable difference

IAD 3.5” DCA 0.8” BWI 0.4” West is best

Wintry AF in Columbia. Vis down to 1/4-1/2mi, blowing like crazy.

Just got home and measured 1.5”. Rockville definitely had more. Being west helped today as I sorta expected it would.

Lightened up in Rockville but a beautiful wintry scene

Hope it’s snowing like this at home in Columbia because it’s crushing in Rockville

About 1” on car tops in Rockville. Bit of a lull, snow down to moderate-light

View out the window from Rockville

Ripping in Rockville.

Looks like probably 1/4-1/2” on cars in Rockville. Temp at home in Columbia down to 33 and all snow per Mrs WxUSAF.

All snow in downtown Rockville. Car tops and mulch whitening.

Using my red tag, I deduce a cold front has passed my house

Was 41F with heavy rain when I left Columbia at 645. Started mixing with sleet on Rt200, all snow and sleet with a temp of 34F when I got to the Rt200/I270 interchange. Same in downtown Rockville where I am for my daughters rock climbing competition that was foolishly not cancelled.

47/46 with light rain.

Blizzard warning issued for the Blue Ridge in VA

Based on turn Super Bowl halftime show, Fiddy could use a drop of fiddy

45.0/40.5

Red!

Storm threads are going to be unreadable

The 200km grid point spacing they use for plotting also seems like a poor decision

You rang?

Sweet! North side of my yard is in the @Ellinwood blue! South side is eating grey. Got to move the snowboard tonight…

More seriously, I like this 12z 3k NAM more than any previous meso runs for MBY. I noticed last night on the super long range hrrr, that it focused a wave of heavier precip through the metro corridors around 12-15z as cyclogenesis intensified to our south, but had it as snow. Earlier NAM runs had that as rain for us, but this NAM finally has it as snow as well. I think that feature is pretty critical to getting accumulation in the metros and lowlands below the fall line. If it’s ripping fatties and 31-34F as advertised, it will accumulate. If that feature is rain and it only turns to snow with that broad diffuse backside anafrontal precipitation, I’m a lot more skeptical of daytime accumulation outside the rural areas.
