Original target was pretty much near Decatur (west of GLE-DTO line). I was concerned about the limited extent (spatially) of the instability, but I figured it would be worth a shot driving down to at least ADM to check things out. I left OUN around 2:30 pm, and I arrived at Courtney approx 1/2 mile N of the Red River (NE of Nocona, TX) not long after 5 pm. Eventually, a storm was able to sustain itself near Nocona (to become the first GLE supercell)... Watched the storm from just ENE of Nocona and sampled 2" hail (
measured - I forgot to include that in the SpotterNet report) at that location. While driving E then S to Saint Jo, I apparently missed the tornado. The base didn't look too impressive when I stayed at the 1st location to sample the hail, which is why I opted to sample the hail vs. to move to stay ahead of the storm. *shrug*
Followed that 1st GLE supercell to I35... It had a nearly ground-scraping wall cloud (and even just ambient cloud base / LCL) at times (not surprising given downstream dewpoint depressions), but I didn't see any ground circulations. The updraft structure of this supercell as it neared GLE was awesome. There was at least one prominent inflow band that arced around the SE through NE part of the updraft, and the updraft itself had a sort of "barrel" appearance. I took a bunch of pics from near the GLE airport, and I haven't had time to process them much. I did quickly convert a RAW to JPG to show some of the structure. It's a shame we didn't have more daylight with which to watch this beauty.
A 2nd supercell developed and intensified W of the 1st GLE supercell, and I headed W to get into better position to view it. Ended up stopping S of Myra, TX, to observe:
Over the next hour, I followed the storm eastward as it went over GLE. Called it quits when the storm looked to weaken as it passed over I35.
Overall, it was a pretty nice chase, particularly given the time of year. I was happy that I didn't commit all the way to Decatur or Weatherford (where the instability corridor was much wider), as I knew I wanted to play the area near the warm front. In addition, there wasn't much of anything in the way of Cu between SEP and Henrietta. It was nice to grab a bite to eat with Amos and co in GLE as well!
