AREAS AFFECTED...CENTRAL OKLAHOMA
CONCERNING...TORNADO WATCH 279...
VALID 172135Z - 172300Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 279 CONTINUES.
SUMMARY...THE SEVERE THREAT FOR WW 279 IS INCREASING, WITH AN
ISOLATED SUPERCELL THUNDERSTORM ONGOING ACROSS CENTRAL OKLAHOMA. ALL
HAZARDS ARE ANTICIPATED, INCLUDING HAIL LARGER THAN 2.00", 65-80 MPH
WINDS, AND TORNADOES.
DISCUSSION...RECENT RADAR IMAGERY SHOWS AN ONGOING SUPERCELL
THUNDERSTORM THAT IS UNDERGOING AN UPDRAFT SPLIT. 20Z OUN SOUNDING
DATA AND KTLX VAD DATA SHOW VERY STRONG LOW-LEVEL SHEAR AND
STREAMWISE VORTICITY THAT WILL FAVOR THE RIGHT SPLIT AND AN EASTWARD
STORM MOTION ALONG THE WARM FRONT, RESULTING IN INCREASED TORNADO
POTENTIAL THIS AFTERNOON INTO THE EVENING. A STRONG TORNADO IS
POSSIBLE WITH THE RIGHT SPLITTING SUPERCELL AS IT APPROACHES AND
CROSSES THE I-35 CORRIDOR IN THE NEXT 1-2 HOURS. ECHO TOPS ON THE
RIGHT-SPLIT OF THE SUPERCELL HAVE INCREASED TO 55 KFT, SUGGESTING
RAPID UPDRAFT INTENSIFICATION. ANY ADDITIONAL THUNDERSTORMS THAT
DEVELOP AND INTERACT WITH THE WARM FRONT WILL BE CAPABLE OF ALL
HAZARDS.
