Ok, here’s a couple. 14” otg so far but it’s very hard to measure with winds at 22G40. CXX Mets were saying this morning that 35-40 dBZ returns below 0°F were nearly unprecedented. Saw lots of that this morning. Storm temps started at 0°F, dropped to -10°F around midnight and have crept up to 1°F, all under a strong SSW WAA regime above 800mb and strong (20+mph) N cold air draining down the Champlain Valley at 925mb. 1”+ per hour rates will continue for another 2-3 hours then taper to snow showers (with 3-5” more after that through tomorrow mid day as the NW flow becomes blocked (with Froude numbers falling below 1.0) and temps crashing to -15 to -20°F and dangerous wind chills of -40°F. Fun stuff!

Looks like the snow survived the rain/warm onslaught last night. Temp just dropped below freezing to 31.1°F so the melting should be over. 2m High temp for the storm was 36.1°F I wont show pics/video from up here in VT unless people want me to.

Checking in from Casa de das–north. First flakes falling up here. Check out that temperature on the car thermometer:

Exactly right, @Bob ChiII. One of the things to watch for.

1.6” for me in Clarksburg. Streets and sidewalks were fully covered.

I’ll banter a bit since we’re in the lull. It’s been a good 20 years in Clarksburg. While further up Parr’s Ridge near @mappyand @psuhoffman certainly do better, it’s been amazingly consistent how often Clarksburg is the high total in the DC (actual) metro area. It’s a great combo of just enough elevation on the ridge, just far enough east so it’s out of the lee shadow of the Appalachians, just low enough to be below CAD inversions and my place is in a depression on NE facing hill so I get cold air drainage into the area and lower sun so the ground stays cold relative to the surrounding areas and I catch every possible flake. It’s like my own tiny microclimate version of the Canaan Valley. Alternately, my place in Vermont where I am spending my weekends now is the exact opposite. I live in the absolute least snowy area in the entire state. It’s so weird to track and report the (relatively) low total when everyone else is “cashing in” around me. Quite the juxtaposition.

I was thinking the same. I’ll get a measurement at my place after the batch that’s blossoming in the western part of the county passes through. The deck railing is new snow from this evening.

I thought you were joking at first. Then I remembered those on the ridge further NE did not do well. I got 13.2" at the southwest end of the ridge.

I fully support this. I'm flying up (to VT) late tonight. Here's the forecast at my place up there. Look at those temps! Saturday: A 30 percent chance of snow after 3pm. Mostly cloudy and cold, with a high near 8. Wind chill values as low as -15. North wind 7 to 10 mph. New snow accumulation of less than a half inch possible. Saturday Night: Snow. The snow could be heavy at times. Low around 3. North wind around 8 mph. Chance of precipitation is 100%. New snow accumulation of 5 to 9 inches possible. Sunday: Snow. The snow could be heavy at times. High near 9. North wind 9 to 15 mph, with gusts as high as 28 mph. Chance of precipitation is 100%. Sunday Night: A 50 percent chance of snow showers. Cloudy, with a low around -5. North wind around 13 mph, with gusts as high as 25 mph.

That’s a trend lately, I see. 1) storms juicer than progged and 2) convergence and N and NW flow stronger as we get closer to game time.

The cutoff was real. This is from 30,000ft as I was approaching the Mason Dixon line:

I hope so. I'll dig it up when I get home. First time using these cams so I hope I set it up right.

First bluebird sky starting to peek out. Can't wait to get home this evening.

Those are lifetime memories you are creating for your son. Good job training him up in the ways that are good and right!!!

13.2" was the total for me in Clarksburg. @ka60 just up the road may have had a bit more as he is usually a tic or two higher than me (Clarksburg ranges from 550' to 810' ASL). 7.2" from the WAA+coastal part of the storm and 6.0" from the ULL.

I can confirm @Ka60‘s 12.5” total. I asked my roommate (who HATES the snow) to go stick my 12” ruler into the snow on the back deck and let me know what the snowdepth was and she flatly said to me, “it disappeared, you’ll have to find it yourself when you get here tomorrow”. LOL.

30 dBZ returns still over Clarksburg. Incredible.

I think I prefer this over a more vertically stacked or phased system since it equals 30 hours of snow. Same basic foot of snow but very different delivery.

I like to use this loop to see the subsidence on the back end of storms coming through. Sure, it's composite but that's helpful in seeing the non (or very light) precip features. It's helpful for the back edge hallucinations that are created by the spine of the mountains to our west as well since LWX radar does not typically see over the ridge tops but KRLX and KBPX can see what's over there. https://www.atmos.washington.edu/~ovens/wxloop.cgi?radar_us_full+/2h/

Check your math, big guy. Western extent is still expanding west.

Latest obligatory deck pic from Casa de das:

Excellent! If u get a total later tonight, can u PM it to me? I don’t land at DCA until 7am tomorrow so I’ll miss measuring when it’s done. Oh, and, you will get dumped on over the next hour. Fun.

One of my favorite cams in Upper MoCo in Germantown. Looking south on 270 from the AWS (weatherbug) HQ building. Realtime Link: https://cameras-cam.cdn.weatherbug.net/AWSHQ/2019/01/13/011320191548_l.jpg

@Ka60 howdy! You have a total for Clarksburg yet? Looks like it’s coming down again. F19D87CD-A651-4CD8-BCB1-C7EB32CE40FB.MP4

Clarksburg is getting deathbanded. 25.7°F/26°F, winds from the SSE at 3mph. 6E42FC48-8156-4955-919C-1605AA69DFDA.MP4
