NWS STORM PREDICTION CENTER NORMAN OK
0340 PM CDT SAT MAY 26 2007
AREAS AFFECTED...EASTERN CO
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 262040Z - 262245Z
POTENTIAL FOR ISOLATED LARGE HAIL MAY DEVELOP OVER THE NEXT FEW
HOURS ACROSS THE CO FRONT RANGE. ALTHOUGH QUESTIONS EXIST REGARDING
THE EXTENT/MAGNITUDE OF THE SEVERE POTENTIAL...WILL MONITOR FOR A
POSSIBLE SEVERE THUNDERSTORM WATCH.
POST-FRONTAL UPSLOPE REGIME CONTINUES TO EVOLVE OVER EASTERN
CO...WITH SURFACE DEWPOINTS GRADUALLY RISING AMIDST LOW LEVEL
SOUTHEASTERLY FLOW...WITH DEWPOINTS WELL INTO THE 40S F ALONG AND
SOUTH OF THE PALMER DIVIDE AS OF 20Z. PERHAPS AIDED BY A LOW
AMPLITUDE MID LEVEL IMPULSE...INSOLATION/HEATING AND SOME ADDITIONAL
INCREASE IN BOUNDARY LAYER MOISTURE WILL BE CONDUCIVE FOR THE
DEVELOPMENT OF ISOLATED STRONG/SEVERE STORMS NEAR THE I-25 CORRIDOR
OVER THE NEXT FEW HOURS. ALTHOUGH MID LEVEL WIND SPEEDS ARE MODEST
/25-30 KT VIA PLATTEVILLE CO PROFILER/...ESPECIALLY WITH SOUTH
EXTENT...VEERING WIND PROFILES MAY ALLOW FOR SOME SUSTAINED
STORMS/SUPERCELL STRUCTURES IN AN ENVIRONMENT WITH MLCAPE VALUES OF
500-750 J/KG. AS STORMS DRIFT EAST-SOUTHEAST THROUGH LATE
AFTERNOON/EARLY EVENING...IT IS QUESTIONABLE HOW FAR EAST STORMS
WILL MAINTAIN A SEVERE THREAT ACROSS THE CO PLAINS GIVEN INHIBITION
IN THE BOUNDARY LAYER.
