Dang…384 hour run of the 12Z GFS is rain free for DFW…
Wonder if the drier trend relates to warmer temps…warmest Nov is 63.5 F set in 2016.

I was worried for my crew mates when I saw them circling in the eye for over 20 mins. Looks like the very rough ride was confirmed. Plane had to leave early. They reported svr turb and a "sawtooth" eye. Looks like they moved 600-700ft up & down during this stretch in ~1 min.

I think I’ll post a tornado I’ve seen per day until this crap ends or I run out of tornadoes. Since I’m 12 days behind, here’s some of the 12 tornadoes I saw on my best stormchase ever way back on May 29, 2004

USS Warrington, a Somers-class destroyer, sank east of the Bahamas. The culprit was the Great Atlantic Hurricane, a powerful Category 4 that peaked on the 13th. Nearly 250 members of the ship's crew were lost.

Puerto Rico was slammed by a Category 5 hurricane. The storm was reported to have damaged or destroyed over 200,000 structures. Massive amounts of crops were destroyed, heavily damaging the island's export industry. Over 300 people were killed.

Hurricane Harvey made landfall at ~10 PM near Rockport, Texas. It was the strongest hurricane to impact America since Wilma in 2005. The Category 4 left behind a record $125 billion in damage (tied with Katrina) and killed 106 people in the United States.

A record forty-two consecutive days of 100° heat finally came to an end at the Dallas-Fort Worth Airport on this day. July 1980 proved to be the hottest July on record with a mean temperature of 92 degrees.

Another issue here is mismatch between public expectation & scientific reality re: what's possible in predicting localized convective extremes (i.e., severe/torrential t-storms). Days/environments supportive of such risk are predictable; exact timing/location/intensity of subsequent extremes is not.
There have been claims that NOAA/NWS did not foresee catastrophic TX floods--but that's simply not true. This was undoubtedly an extreme event, but messaging rapidly escalated beginning ~12 hrs prior. Flood Watch mid PM, "heads up" outlook late PM, flash flood warnings ~1am.
WPC issued as many as six MPDs for the deadly flash flooding in the TX Hill Country starting yesterday evening and lasting through much of today. The first MPD generally set the stage for what was to come, while the next three shown were as the event unfolded.

The Texas floods over the last 2 days were predominantly associated with a long-lasting mesoscale convective vortex (MCV), but notice how there are multiple discrete rainfall maxima shown in the contours, each associated with different rainfall rates, duration, and phenomenon:

What a night working radar/warning ops for NWS Norman during their AWIPS upgrade ⛈️ I ended up issuing 17 svr tstorm warnings and 5 tornado warnings across Oklahoma 😮 Quite a fascinating supercell/QLCS event. Sorry to my Norman friends for setting off the sirens/phones and waking you up 🫤

International Falls, MN hit 95 today. They hit 95 this year before Memphis, Dallas, Houston, Atlanta, Charlotte, Little Rock, and New Orleans. They now have as many 95 degree days through May 11 as San Antonio, Austin, and El Paso.
