AREAS AFFECTED...PARTS OF NORTHERN AND CENTRAL OKLAHOMA
CONCERNING...SEVERE THUNDERSTORM WATCH 483...
VALID 112342Z - 120145Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 483
CONTINUES.
SUMMARY...THE THREAT FOR ISOLATED SEVERE WIND GUSTS IS EXPECTED TO
PERSIST THIS EVENING. HOWEVER, THE POTENTIAL FOR ORGANIZED COLD POOL
DEVELOPMENT REMAINS UNCERTAIN.
DISCUSSION...MAINLY PULSE-TYPE STORM MODES HAVE BEEN OBSERVED OVER
THE PAST 1-2 HOURS WITH RECURRING INITIATION FOCUSED ALONG COLLIDING
STORM-SCALE OUTFLOWS AND THE WESTERN EXTENSION OF A SYNOPTIC FRONT
ANALYZED ACROSS NORTHERN OK. LATEST OBJECTIVE ANALYSIS INDICATES
THAT THE STRONGEST INSTABILITY (MLCAPE OF 2000-3000+ J/KG) IS
LOCATED OVER NORTHEAST OK IN THE VICINITY OF THE STALLED FRONT,
WHERE DEWPOINTS ARE IN THE MID 70S. BOTH BOUNDARY-LAYER MOISTURE
CONTENT AND RESULTANT INSTABILITY DECREASE WITH WESTWARD EXTENT;
HOWEVER, LOW-LEVEL LAPSE RATES BECOME STEEPER.
REGIONAL VWPS INDICATE DEEP-LAYER SHEAR OF GENERALLY LESS THAN 30 KT
ACROSS THE AREA, WHICH SHOULD TEND TO LIMIT THE POTENTIAL FOR
ORGANIZED STORM MODES. AS SUCH, THE CURRENTLY OBSERVED PULSE STORMS
ARE EXPECTED TO CONTINUE THIS EVENING WITH AN ASSOCIATED RISK FOR
LOCALLY SEVERE WIND GUSTS AND PERHAPS SOME MARGINALLY SEVERE HAIL.
THE POTENTIAL FOR AN ORGANIZED COLD POOL CAPABLE OF MORE
CONCENTRATED SEVERE WIND GUSTS WILL BE CONTINGENT ON THE FAVORABLE
CLUSTERING OF STORMS, WHICH HAS YET TO BECOME APPARENT.
