AREAS AFFECTED...PORTIONS OF CENTRAL AND EASTERN OKLAHOMA INTO
SOUTHEASTERN KANSAS AND FAR SOUTHWESTERN MISSOURI
CONCERNING...TORNADO WATCH 121...
VALID 152055Z - 152200Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 121 CONTINUES.
SUMMARY...A SEVERE WIND AND HAIL THREAT SHOULD PERSIST FOR SEVERAL
MORE HOURS, AND A COUPLE TORNADOES REMAIN POSSIBLE.
DISCUSSION...MULTIPLE SUPERCELL THUNDERSTORMS HAVE DEVELOPED OVER
THE PAST COUPLE OF HOURS OVER PORTIONS OF NORTHEASTERN OK INTO
SOUTHEASTERN KS, WHERE SEVERE HAIL HAS BEEN REPORTED. ADDITIONAL
STORMS HAVE RECENTLY MATURED OVER NORTHWESTERN TX AND ARE
APPROACHING THE RED RIVER. ALL OF THESE STORMS ARE TRAVERSING THE
WARM SECTOR IMMEDIATELY AHEAD OF THE DRYLINE, WHERE 2500+ J/KG
MLCAPE AND OVER 60 KTS OF EFFECTIVE BULK SHEAR RESIDES. AS SUCH,
SUPERCELLS SHOULD PERSIST FROM THE RED RIVER TOWARD THE OZARKS FOR
SEVERAL MORE HOURS, ACCOMPANIED BY A SEVERE WIND/HAIL THREAT.
REGIONAL VADS SHOW MODEST SPEED SHEAR CONTRIBUTING TO ELONGATED
HODOGRAPHS, BUT WITH LITTLE LOW-LEVEL CURVATURE, SO TORNADO
POTENTIAL APPEARS MODEST. STILL, A COUPLE OF TORNADOES CANNOT BE
RULED OUT IF SUPERCELLS CAN PERSIST IN A DISCRETE FASHION. THE
GREATEST SHORT-TERM SEVERE THREAT EXISTS WITH ONGOING STORMS IN
NORTHEASTERN OK, WHERE VERTICAL WIND SHEAR IS LOCALLY STRONGER.
