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.

Woooohoooo NFC East leaders! Ignore the current stats though.

Record is 74 for today at DCA. ...and 75F at IAD and 72F at BWI.

Close lightning/loud thunder or just visible lightning/audible thunder?
