Congrats to you all as always! 2.25" at IAD 1.48" at DCA 1.04" at BWI

You must be close to me. I'm in Herndon and measured about 0.3" give or take in 5 minutes.

@MillvilleWx THIS! La Plata gets enough exciting tornadoes to keep them entertained for a while. They will be fine.

Experienced 3-4"/hr snowfall rates w/ 45-50 mph wind gusts through the wee hours this morning. I even witnessed thundersnow thrice! The wait for a storm to take advantage of this pattern was definitely worth it. It's unfortunate that Ji couldn't just enjoy the storm instead of worrying about the back-edge. He may be the first poster to ever get reaped by da reaper in the middle of a HECS. @WxWatcher007 is this true?... about this being the first reaping to take place during a HECS? Btw, one of those lightning strikes may have been your reaping now that I think about it. The flash that I saw fits with the time of Ji's reaping.

BTW, here's the ONI data since 1950 for those curious. https://origin.cpc.ncep.noaa.gov/products/analysis_monitoring/ensostuff/ONI_v5.php

It was the Feb 12-13, 2014 event. Cool Neutral.

Some runs of the gfs yesterday, particularly the 12z and 18z runs, were aggressive with getting convective snow showers east of the mountains on Christmas morning. We'll see if it becomes more aggressive again and eventually if CAMs pick up on this closer in time.

Very light snow w/ moderate-sized flakes. (Herndon, VA) Fifth time there've been flakes this season. Sixth day there've been flakes. December 7th,9th,14th,16th,17th,18th.

Meteorological (or Climatological ) Winter is upon us!

The Great Mid-Atlantic Arctic Severe Squall Event of 2020 Note: Tornadoes were not at their peak intensity along their whole path as the tornado path lines may falsely imply.

IAD got down to 28F this morning. RIP one-minute obs at IAD. A coating of frost is on the grass.
