CONCERNING...SEVERE THUNDERSTORM WATCH 79...

VALID 110036Z - 110230Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 79
CONTINUES.

SUMMARY...A THREAT FOR LARGE HAIL AND WIND DAMAGE WILL CONTINUE FOR
SEVERAL MORE HOURS ACROSS WRN AND CNTRL OK. A TORNADO THREAT MAY
ALSO DEVELOP DURING THE MID TO LATE EVENING.

DISCUSSION...THE LATEST RADAR TRENDS SHOW A CLUSTER OF STRONG TO
SEVERE THUNDERSTORMS IN NW OK WITH ANOTHER NORTH TO SOUTH ORIENTED
CLUSTER ACROSS SW OK. THE STORMS ARE LOCATED ALONG A CORRIDOR OF
MODERATE INSTABILITY ORIENTED SOUTHWEST TO NORTHEAST FROM NW TX NEWD
INTO FAR SE KS. MODERATE INSTABILITY IS EVIDENT ON THE 00Z OKC
SOUNDING WHICH HAS MLCAPE NEAR 2800 J/KG. IN ADDITION...THE SOUNDING
SHOWS 0-6 KM SHEAR NEAR 30 KT WITH A 700-500 MB LAPSE RATE NEAR 8.0
C/KM. THIS ENVIRONMENT SHOULD SUPPORT A LARGE HAIL THREAT WITH
ROTATING CELLS. WIND DAMAGE WILL ALSO BE POSSIBLE WITH DISCRETE
ROTATING STORMS AND ALONG THE LEADING EDGE OF SHORT LINE SEGMENTS. A
40 TO 55 KT LOW-LEVEL JET IS FORECAST TO STRENGTHEN ACROSS NW TX AND
SW OK OVER THE NEXT COUPLE OF HOURS. THIS WILL INCREASE DEEP-LAYER
AND LOW-LEVEL SHEAR DURING THE MID TO LATE EVENING. AS A
RESULT...CONDITIONS MAY BECOME MORE FAVORABLE FOR SUPERCELLS AND A
TORNADO OR TWO WILL BE POSSIBLE.
