Ground Scouring Posted May 30, 2013 Share Posted May 30, 2013 People are evacuating Cashion. There are already hints of a BWER developing over Cashion (and another near Anadarko). The lowering is growing more evident. Link to comment Share on other sites More sharing options...

HM Posted May 30, 2013 Share Posted May 30, 2013 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.

Superstorm93 Posted May 30, 2013 Share Posted May 30, 2013 Lovell cell might try and screw with the Cashion cell These MDT risks over the past few weeks have really only produced one or two truly isolated supercells that can put down long track tornadoes Link to comment Share on other sites More sharing options...

HM Posted May 30, 2013 Share Posted May 30, 2013 For the record, metro area surface winds are all around 180° at 19z. Everyone is firmly entrenched in the departing LLJ, greater than 30 knots. Link to comment Share on other sites More sharing options...
cstrunk Posted May 30, 2013 Share Posted May 30, 2013 We still have mostly S to SSW winds at the surface, which I think is hindering the tornado potential at the moment. We'll have to keep an eye on that as the afternoon progresses. Link to comment Share on other sites More sharing options...

DDweatherman Posted May 30, 2013 Share Posted May 30, 2013 The cell passing Anadarko has taken a right-hand turn, so Moore might be dodging a bullet down the road. IF that were to go tornadic, I don't see how it wouldn't turn a bit more a pass to their south. Link to comment Share on other sites More sharing options...

thunderbird12 Posted May 30, 2013 Share Posted May 30, 2013 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.

DDweatherman Posted May 30, 2013 Share Posted May 30, 2013 I think some SW winds in addition to the meager LL lapses could be hindering significant tornadic development than we could be seeing overall if those aspects were different. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

Buckeye05 Posted May 30, 2013 Share Posted May 30, 2013 Chickasha storm is about to produce - video/radar confirm a much tighter wall cloud with stronger rotation. I wouldn't bet on it. Has more of an appendage than a true curving hook. That kind of radar signature rarely seems to produce much. Link to comment Share on other sites More sharing options...
