NaoPos Posted May 30, 2013 Share Posted May 30, 2013 Chickisha cell is still struggling. Volume scan shows that there's no evidence of an impressive anvil ScreenHunter_46 May. 30 15.20.png Good look.

Superstorm93 Posted May 30, 2013 Share Posted May 30, 2013 I wouldn't bet on it. Has more af an appendage than a true curving hook. That kind of radar signature rarely seems to produce much. Yeah, I highly doubt it produces over the next 15-20 minutes TOKC shows the appendage really well and how little rotation this cell has. Link to comment Share on other sites More sharing options...
NaoPos Posted May 30, 2013 Share Posted May 30, 2013 If they can stay discrete for another hour or so, they could get interesting. Between the subsidence and questionable wind profiles, they're struggling to go tornadic. Link to comment Share on other sites More sharing options...

SmokeEater Posted May 30, 2013 Share Posted May 30, 2013 MESOSCALE DISCUSSION 0882 NWS STORM PREDICTION CENTER NORMAN OK 0235 PM CDT THU MAY 30 2013 AREAS AFFECTED...CNTRL/ERN OK...WRN AR...FAR SWRN MO CONCERNING...TORNADO WATCH 252...253... VALID 301935Z - 302030Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 252...253...CONTINUES. SUMMARY...GREATEST TORNADO THREAT EXISTS NEXT COUPLE OF HOURS WITH SEMI-DISCRETE SUPERCELLS ACROSS CNTRL INTO NERN OK AND SUPERCELLS EMBEDDED WITHIN A BROADER CLUSTER ACROSS FAR SERN OK/WRN AR. LARGE HAIL IS ALSO POSSIBLE WITH THE WRN SUPERCELLS. DISCUSSION...LOW-LEVEL WIND PROFILES ARE STRONGEST AND MOST FAVORABLE FOR TORNADOES IN ERN OK/WRN AR PER TULSA/FORT SMITH VWP DATA. HERE...0-1 KM SHEAR OF 30-35 KT HAS PERSISTED AND LARGELY IS AIDING IN THE DEVELOPMENT OF A FEW MODERATE TO STRONG MESOCYCLONES ACROSS FAR W-CNTRL AR. CONTINUED WAA ATOP SHALLOW CONVECTIVE OUTFLOW SHOULD FOSTER RENEWED UPDRAFTS WITH A PERSISTENT RISK FOR A FEW TORNADOES. FARTHER W...SUPERCELLS ACROSS CNTRL OK HAVE PROGRESSED OFF THE DRYLINE INTO A STRONGLY UNSTABLE AIR MASS PER 18Z OUN RAOB. ALTHOUGH LOW-LEVEL WIND PROFILES ARE NOT QUITE AS FAVORABLE AS FARTHER E...THEY ARE STILL SUFFICIENT FOR A RISK OF TORNADO DEVELOPMENT...WHERE ONE MIGHT BECOME STRONG GIVEN THE DEGREE OF BUOYANCY. HOWEVER...WITH LARGE-SCALE DRYING/WARMING OCCURRING /INFERRED BY WATER VAPOR IMAGERY/...SUPERCELLS HAVE SHOWN EVIDENCE OF STRUGGLING TO BECOME VERY INTENSE. ..GRAMS.. 05/30/2013 Link to comment Share on other sites More sharing options...
jojo762 Posted May 30, 2013 Share Posted May 30, 2013 Lunch sounds like a good idea... I'm gonna check back up in an hour. Storms thus far have been pretty unimpressive, still a lot of time for things to ramp up though. Seems like if ANY storms were to develop in Kansas in a few hours, when the moisture has somewhat returned along with the instability they COULD get something there, maybe. Doubt any storms will form though, no signs of convective development whatsoever up there. Also wouldn't be entirely surprised to see a downgrade to a Slight Risk in the next update... SPC seemed pretty unimpressed with development so far. Link to comment Share on other sites More sharing options...
Ground Scouring Posted May 30, 2013 Share Posted May 30, 2013 Winds rapidly backing due to mesolow forming N of CSM, OK (1930Z)...maybe localized, enhanced updrafts and shear can offset the large-scale subsidence. Link to comment Share on other sites More sharing options...
