   NWS STORM PREDICTION CENTER NORMAN OK

   AREAS AFFECTED...ERN TX PNHDL AND NWRN TX INTO WRN AND CNTRL OK
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 364...
   
   VALID 101835Z - 102000Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 364
   CONTINUES.
   
   THROUGH 20Z...THE GREATEST THREAT OF SEVERE STORMS WILL EXIST ACROSS
   ERN HALF OF WW AREA.
   
   MCS CONTINUES TO EVOLVE THIS AFTERNOON WITH MOST INTENSE STORMS
   LOCATED ALONG ERN AND SRN PERIPHERY OF LARGER CONVECTIVE
   SHIELD...NAMELY FROM WILBARGER COUNTY TX AND JACKSON/TILLMAN
   COUNTIES OK NEWD INTO CADDO AND BLAINE COUNTIES OK AS OF 1820Z.  18Z
   MESOANALYSIS INDICATES THAT POCKETS OF STRONGER HEATING HAVE
   OCCURRED OVER PORTIONS OF NWRN TX AND N-CNTRL INTO NERN OK WHERE
   TEMPERATURES HAVE WARMED THROUGH THE 80S.  MOREOVER...ONGOING STORMS
   ARE BEGINNING TO INTERACT WITH THE WRN EDGE OF RICHER BOUNDARY LAYER
   MOISTURE WHICH IS LIKELY RESULTING IN REDUCED CONVECTIVE INHIBITION
   AND MODERATE CONVECTIVE INSTABILITY.
   
   THUS FAR...ASOS AND OK MESONET OBSERVATIONS INDICATE A NUMBER OF
   WIND GUSTS GREATER THAN 50 MPH IN ASSOCIATION WITH THE MOST INTENSE
   STORMS.  GIVEN THE STRENGTHENING TROPOSPHERIC FLOW OBSERVED BY
   UPSTREAM VWPS AND PROFILERS AND THE DECREASING STABILITY...EXPECT
   TSTMS TO CONTINUE TO INCREASE IN COVERAGE AND INTENSITY THIS
   AFTERNOON OVER PARTS OF WRN INTO CNTRL OK.  DAMAGING WINDS WILL
   REMAIN THE PRIMARY THREAT...THOUGH HAIL WILL BECOME INCREASINGLY
   POSSIBLE AS AIR MASS FURTHER DESTABILIZES.
