MESOSCALE DISCUSSION 1324
  NWS STORM PREDICTION CENTER NORMAN OK
  0321 PM CDT MON JUN 20 2011
 
  AREAS AFFECTED...CENTRAL/EASTERN OK AND NORTH-CENTRAL TX
 
  CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
 
  VALID 202021Z - 202145Z
 
  AS A SUPPLEMENT TO EARLIER MESOSCALE DISCUSSION 1320...VISIBLE
  SATELLITE IMAGERY OVER THE PAST HOUR REFLECTS INCREASING HIGH BASED
  CU ALONG THE DRYLINE FROM WEST-CENTRAL OK SOUTHWESTWARD INTO TX NEAR
  THE ABILENE AREA. AS LARGE SCALE FORCING FOR ASCENT CONTINUES TO
  OVERSPREAD THE REGION AND REMAINING CINH WANES...IT SEEMS LIKELY
  THAT AT LEAST SCATTERED DEEP CONVECTION WILL INITIATE/INCREASE
  THROUGH THE 21Z-23Z TIMEFRAME. A WATCH WILL LIKELY BE ISSUED SHORTLY
  FOR AT LEAST PORTIONS OF CENTRAL/EASTERN OK...WITH A WATCH ALSO
  POSSIBLE ACROSS PORTIONS OF NORTH-CENTRAL TX WHERE SOMEWHAT MORE
  ISOLATED SEVERE DEVELOPMENT IS ANTICIPATED. AN INITIAL SUPERCELLULAR
  LARGE HAIL/SOME TORNADO THREAT WILL EXIST ESPECIALLY ACROSS
  OK...BEFORE A DAMAGING WIND THREAT LIKELY EVOLVES THROUGH EARLY
  EVENING.
