Nine years ago today, the shelf cloud went directly over us in Cathedral Heights. This was when my desk was next to the Glass Enclosed Nerve Center. The actual severe thunderstorm followed soon after.

ATTN, fellow weather nerds (mostly meteorologists): this is sick (as the kids say)! Check out the isolated t'storms quickly growing as the cap breaks and the anvil tops are blowing east to west. [imagery COD] #meteorology #science #DCwx #VAwx #MDwx

#Metallica update: still on track from the constant, non-stop pouring rain to taper to spotty showers and drizzle between 4p-6p. Cool, damp, and drizzly through the show, unfortunately.

And there it is! More snow for us from the remnants of the upper low that moves over us overnight into the morning on Thursday. This is the energy that if it had phased with the southern stream in the Deep South would have led to a big storm.

Oh, it's snowing aloft, but like we talked about yesterday, tremendously dry air in the low levels is just destroying it. That's why no data under 3k ft. I believe ultimately we'll get a dusting out of the upper low remnants tonight/tomorrow AM a la 12z HRRR. Hampton Roads coastal storm long gone.

36 hrs away from the start of the event and the SREF plumes look like this??? What kind of data is getting into the deterministic models, or are the physics of the current setup too complex? Note the mean (black line) is much higher than the recent "nothing" amounts. /jargonformeteorologists

It has us.

Doppler radar "donut hole" is shrinking rapidly, so precipitation is getting closer and closer to the ground. With temps in the mid 30s and dewpoints in the teens, I think we'll start off as a mix of rain and sleet briefly before changing over to all snow. HRRR has that scenario. #DCwx #VAwx #MDwx

Obv. ice early Thursday morning this week, possibly Sat. morning, and then a potential storm of some variety around this time next week.

Man, I hope that #snowsquall breaks up before it gets to Interstate 80 in #Pennsylvania. Why do I feel like this is going to lead to something very bad? Snow squall #warnings in effect all the way up into New York state. Radio stations in PA, you gotta be on the air right now talking about these

I got this awesome #SunPillar this morning on #WMATA's Blue Line as we were coming into DCA. As usual, my phone washes it out too much, and the contrast was much better to the naked eye. Still, awesome. Moving on, let's thaw out now.

The Annual Meeting of the @ametsoc.bsky.social missed this by one week in #NewOrleans. 😂 #AMS2025

Newspaper report to @NWSHouston
of 3.25" of snow in #Houston and that's inside Loop 610. Just wow. Closest airport is #Hobby which is reporting heavy snow in visibility of 1/4 mile. #Houston #HTX #Htown #TXwx #Texas #TexasWeather

The smoke from the #PalisadesWildfire and others is so thick that it is showing up on dual-polarity doppler radar. It looks like some of the embers are so large that the algorithm is detecting them as "big drops" (second image). #CaliforniaWildfires #Malibu #LosAngeles

The dry low levels are being overcome by the rain and it will start reaching the gorund in the Beltway region by 3:30p at the latest. Damp roads for the evening rush (and tomorrow morning). #DCwx #VAwx #MDwx

Got an account here just to post this. #BT #ToriAmos
