Plains tornado threat Mon 5/27-Fri 5/31

The Anadarko cell looks certain to come very close to Moore in another hour and a half...and given the increasing SRH down there, the Southern cell looks like a good chase until it gets closer to OKC. The cell will face an increasingly favorable environment just ahead. Ch. 9 chopper shows "significant" rotation and a possible wall cloud developing just SSW of Cashion, OK. TOR just issued there based upon sirens, but no actual TOR yet as circulation continues to develop.

It's almost ridiculous that these storms developed just in time. Basically, they formed at the heels of an exiting LLJ with 850mb winds 25-35 kts. Their speed will keep them firmly embedded within favorable low-level winds. :(

Thus far, the Anadarko and Guthrie supercells have stayed rather small in size and the anvil plumes are pretty narrow, which suggests they may be fighting some large-scale subsidence. Also, the 18Z OUN sounding still had backing mid-level flow and a big loop in the hodograph, which usually isn't what you see in a tornadic supercell environment. The wind profile will probably become more classic with time (albeit with slowly weakening low-level flow), but any issues with subsidence will likely remain.

I noticed the slight mid-level backing too and the exiting LLJ. The 0-1 SRH has taken a hit to some extent but still sufficient. On 5/20, while the low-level winds were not quite favorable midday, the wind profile was classic and improving beyond 17z. Hopefully these differences prevent something like 5/20 from repeating...at least over the metro area in the next couple of hours.
