Among a handful of other random trivia facts, the newly rated EF-5 Enderlin tornado is now the shortest-lived EF-5 on record (19 minutes), as well as the furthest north American EF-5 on record (~46°N latitude)

We just passed the 72nd anniversary of the first tornado to be detected by radar - 4/9/53, in Champaign County, Illinois. This particular tornado was captured by the radar at Willard Airport and was photographed by Don Skaggs, who used a 35mm film camera mounted atop the A-scope

OTD 9 years ago: I got up close and personal with this multivortex EF-3 tornado between Como and Sardis, MS - this same supercell would later go on to produce an EF-4 near Holly Springs which unfortunately killed 9 people

I've been in hibernation in this quiet spell of weather, but radar is useful for more than just tornadoes and QLCS'... up in Nome, Alaska, icebergs galore are being tracked in their natural flow up and down the coast using an X-band radar #akwx

All sorts of helicopter/plane activity today on the X-band here in S TN. Composite of the last 10 mins beautifully shows aircraft tracks #tnwx

Just experienced my first BlueSky outage. They grow up so fast…

2/16/23 - an otherwise relatively innocuous enhanced risk day in the Tennessee Valley produces a family of EF-0/1 tornadoes within 10km from my teams radar, yielding the best resolution (both spatially & temporally) data we’ve yet gathered of tornadogenesis, featuring vortex holes & all! #tnwx

OTD '89: Huntsville, AL saw the worst tornado in it's history; the notorious Airport Road F-4. Apartment buildings & entire commercial blocks were eviscerated; duplexes were swept clean from their foundation, & 1000s of cars were thrown and mangled - 21 people died, most of them in cars. (1/3)

Archival data of KHTX (left) vs. my team's X-band radar (right) from the Prospect, TN EF-2 on 5/8/24, in which R = Zdr, G = dBZ, B = CC. X-band was scanning the tornadic vortex at 256ft compared to KHTX at 5400ft.
Zdr arc was very intense and omnipresent @ this time near tgen as seen on X-band.

Recently re-discovered some old photos taken by a Lawrence Co., TN spotter of the April 8th, 1998 "Forgotten F5" in Southern TN.
This tornado fortunately took no lives, but nevertheless was very violent, & was largely usurped in the media by the more well-documented Nashville F3 the same day. #tnwx

Comanche dodged a major bullet last night. That sort of scouring and shredding of debris leads me to think this thing with it's relatively narrow vortex could have crept up to violent territory at times #okwx

Bryan Wilson is now Chase Wilson!
No, look; my entire life - since the day I was born - I've gone by my middle name, Chase. I just went with the formality of my first name, Bryan, but nobody in my life (seriously, not a single teacher, partner, or relative) called me that pre-wx. Chase forever!

Hurricane #Kristy showing some incredible mesovort action, as well as more of those wispy spiraling cloud features in the eye this afternoon

Harry Weinmans tornado/TDS frequency data shown at SLS also by proxy shows an issue my team is working to solve - the radar gaps in CONUS. Ours in the Tennessee Valley is currently somewhat covered by our X-band which has warned several tornadoes missed by NEXRAD… but more powerful systems needed

@tlyza89.bsky.social: The current EF-5 tornado drought is highly unlikely to be natural going back to 1880 based on statistical analysis #31SLS
…and I believe it. 2013 was not a mysterious 200mph temporal firewall for tornadoes.
Fujita's "legacy" intuition was probably quite close to reality

I’m glad I don’t do sports, so that my team never loses.
I’m on team radar.
And radars never lose.

Eastern NM today is probably a setup I'd chase if I lived within 50 miles... As far as Clovis specials are concerned, I reckon I could work with this #nmwx

Another fun day with the battle-proven DOW-6 & welcoming FARM to Dixie Alley (plus, catching up with Josh and Karen is always a real treat)
