   MESOSCALE DISCUSSION 0353
   NWS STORM PREDICTION CENTER NORMAN OK
   0736 PM CDT SUN APR 10 2016

   AREAS AFFECTED...NW TX...WRN AND CNTRL OK

   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.
