CONCERNING...SEVERE THUNDERSTORM WATCH 80...
VALID 110142Z - 110345Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 80
CONTINUES.
SUMMARY...A LARGE HAIL AND WIND DAMAGE THREAT WILL CONTINUE FROM NE
OK NEWD INTO CNTRL MO THIS EVENING. A BRIEF TORNADO CAN NOT BE RULED
OUT AS LOW-LEVEL FLOW INCREASES OVER THE NEXT FEW HOURS.
DISCUSSION...THE LATEST RADAR TRENDS SHOW A CLUSTER OF STRONG
THUNDERSTORMS LOCATED IN THE CNTRL PORTION OF WW 80 NEAR THE KS-OK
STATELINE WHILE A SECOND CLUSTER IS LOCATED JUST TO THE SOUTHWEST OF
THE WATCH IN NRN OK. THIS ACTIVITY IS BEING FUELED BY AN AXIS OF
MODERATE INSTABILITY EXTENDING FROM CNTRL OK INTO FAR SE KS WHERE
MLCAPE VALUES ARE ESTIMATED IN THE 1500 TO 2000 J/KG RANGE. IN
ADDITION...WSR-88D VWPS AT TULSA OK AND SPRINGFIELD MO SHOW 0-6 KM
SHEAR AROUND 40 KT. THIS ALONG WITH STEEP LAPSE RATES WILL BE ENOUGH
FOR SUPERCELL DEVELOPMENT AND LARGE HAIL. LAPSE RATES ARE STEEPEST
ACROSS THE SWRN AND CNTRL PART OF WW 80 SUGGESTING THE LARGE HAIL
THREAT WILL BE GREATEST THERE. WIND DAMAGE WILL ALSO BE POSSIBLE
WITH THE BETTER ORGANIZED DOWNDRAFTS. AS LOW-LEVEL FLOW INCREASES
LATE THIS EVENING...A BRIEF TORNADO ALSO CAN NOT BE RULED OUT.
