Yeap. It was Election Day.

Reminds me of the weather in this region on November 3rd this past year w/ a deck of clouds extending from wsw/sw to ene/ne... But you said it was during the summer so I don't know for sure whether you are talking about the event I mentioned or a different one as those "standing cloud-deck features" actually occur at least occasionally every year, though usually not as frequently in the summer.

Another year is over and, like always, I'm a curious and noisy young man. What weather event(s) stood out for you personally in the past year? For me despite a very boring year in general I lucked into two decent (by MBYs standards) thunderstorms on June 4th and June 22nd. Both storms featured sheets of rain w/ 40-45mph wind gusts. The June 4th storm dropped the visibility to below 400 feet at one point. I know I know a lot of you will happy about that but MBY usually gets missed way more often than not. Welp, how about you guys? What event(s) stood out to you this past year (2020)?

FYI: Para-gfs is updating on tropicaltidbits again.

Lol.

What snowfall rates are you anticipating in your region should this band develop? Any chance at thundersnow?

Mega front classification (though I may have to double check this): 20F/hr 30F/6hr 40F/12hr 50F/24hr

Dec 7,9,14,25: T Dec 16-17: 2.1" Dec 18: 0.2" Stats: Trace on Christmas! Most snow received on Christmas day since 2010. 7 days with flakes through Dec 25th.

Merry Christmas to my fellow weather weenies! May we all be blessed with a surprise 6"/hr snowfall today that buries our worries away.

Yeah. I've given up tryin to figure out 2021. Summer weather in the winter then it gets colder until it starts snowing once we get into meteorological summer. In all seriousness though, Merry Christmas to you.

You celebrate Christmas on June 25th?... Cool.

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.

Fixed.

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.

... And Dulles has dropped to 31F after being at 34F earlier this evening.

There's an orange tinge to the sky here in Herndon with the sunset.
