MESOSCALE DISCUSSION 1072
NWS STORM PREDICTION CENTER NORMAN OK
0220 PM CDT TUE JUN 05 2012
AREAS AFFECTED...PORTIONS OF SOUTHWEST OK AND TX PANHANDLE
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 051920Z - 052045Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...THUNDERSTORMS WILL CONTINUE TO DEVELOP THROUGH THE
REMAINDER OF THE AFTERNOON. THE STRONGEST STORMS MAY PRODUCE STRONG
WIND GUSTS AND HAIL. THE SEVERE THREAT IS EXPECTED TO REMAIN
SUFFICIENTLY ISOLATED THAT A WW IS NOT ANTICIPATED ATTM.
DISCUSSION...THUNDERSTORMS HAVE DEVELOPED TO THE NORTH OF AN MCV
WHICH HAS BEEN NEARLY STATIONARY ACROSS THE SRN PANHANDLE AND SOUTH
PLAINS. THIS AREA IS ALONG THE INSTABILITY GRADIENT RESULTING FROM
DIFFERENTIAL HEATING AND IN AN ENVIRONMENT WHERE A BELT OF STRONGER
MID LEVEL EASTERLY WINDS EXISTS AS DEPICTED BY THE LATEST KAMA VWP.
THIS SETUP MAY LEAD TO ORGANIZED WESTWARD-MOVING MULTICELL STORMS
POSING A RISK OF STRONG WINDS AND HAIL THROUGH THE REMAINDER OF THE
AFTN.
THE SEVERE THREAT SHOULD REMAIN SUFFICIENTLY ISOLATED TO PRECLUDE A
WW.
