   MESOSCALE DISCUSSION 0290
   NWS STORM PREDICTION CENTER NORMAN OK
   0354 PM CDT WED MAR 30 2016

   AREAS AFFECTED...PORTIONS OF WRN N INTO N-CNTRL TX...WRN/CNTRL
   OK...AND S-CNTRL KS

   CONCERNING...SEVERE THUNDERSTORM WATCH 58...59...

   VALID 302054Z - 302230Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   58...59...CONTINUES.

   SUMMARY...LARGE HAIL CONTINUES TO BE THE MAIN THREAT WITH ONGOING
   STRONG/SEVERE THUNDERSTORMS ACROSS WW 58 AND 59. AN EWD EXPANSION OF
   BOTH WATCHES MAY BE NEEDED OVER THE NEXT HOUR OR TWO IN OK/TX.

   DISCUSSION...TWO AREAS OF SCATTERED SEVERE THUNDERSTORMS ARE ONGOING
   AS OF 2045Z...ONE OVER S-CNTRL KS/N-CNTRL OK...AND ANOTHER ACROSS
   S-CNTRL OK INTO WRN N TX AND N-CNTRL TX. IN BETWEEN THESE CLUSTERS
   OF THUNDERSTORMS...A GAP IN THUNDERSTORM DEVELOPMENT IS EVIDENT
   ACROSS MUCH OF CNTRL OK WHERE CONVECTION OCCURRED EARLIER THIS
   MORNING. MANUAL OBSERVATION AND VISIBLE SATELLITE IMAGERY ALSO SHOWS
   SUPPRESSED CUMULUS...SUGGESTING THE SEVERE RISK ACROSS MUCH OF CNTRL
   OK WILL REMAIN LIMITED IN THE SHORT TERM.

   ACROSS N-CNTRL OK AND S-CNTRL KS...MULTIPLE LARGE HAIL REPORTS OF
   1-2 INCHES HAVE BEEN RECEIVED WITH SPLITTING SUPERCELLS BEING
   OBSERVED. FURTHER S ACROSS S-CNTRL OK INTO WRN N TX/N-CNTRL
   TX...CONVECTION HAS REMAINED MORE ISOLATED. A SIMILAR
   THERMODYNAMIC/KINEMATIC ENVIRONMENT FOR BOTH OF THESE REGIONS WILL
   REMAIN FAVORABLE FOR A LARGE HAIL THREAT...WITH ISOLATED DAMAGING
   WINDS ALSO POSSIBLE. THE TORNADO THREAT REMAINS RELATIVELY LOW
   ACROSS BOTH SEVERE THUNDERSTORM WATCHES AS AREA VWPS SUGGEST
   LOW-LEVEL WINDS REMAIN VEERED TO THE SW. AN EWD EXTENSION OF WW 58
   AND 59 MAY BE NEEDED IN THE NEXT HOUR OR TWO FOR PARTS OF S-CNTRL OK
   INTO N-CNTRL/NERN TX AS ADDITIONAL CONVECTION FORMS/MOVES INTO THESE
   AREAS.
