MESOSCALE DISCUSSION 1884
NWS STORM PREDICTION CENTER NORMAN OK
0307 PM CDT MON AUG 04 2025
AREAS AFFECTED...THE CENTRAL HIGH PLAINS
CONCERNING...SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY
VALID 042007Z - 042200Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...ISOLATED SUPERCELLS CAPABLE OF VERY LARGE HAIL, SEVERE
GUSTS, AND A BRIEF TORNADO OR TWO ARE POSSIBLE ACROSS PARTS OF THE
CENTRAL HIGH PLAINS. A SINGLE OR PAIR OF SEVERE THUNDERSTORM WATCHES
WILL LIKELY BE NEEDED.
DISCUSSION...WIDELY SCATTERED HIGH-BASED CU/CBS HAVE BEEN NOTED FROM
THE LARAMIE MOUNTAINS TO PIKES PEAK, WITH ISOLATED DEVELOPMENT ALONG
THE SOUTH PLATTE AND AR VALLEYS IN EASTERN CO. MUCH OF THIS INITIAL
ACTIVITY IS OCCURRING WHERE SURFACE DEW POINT DEPRESSIONS OF 35-45 F
ARE COMMON. THIS SUGGESTS CONVECTION MAY STRUGGLE TO RAPIDLY
INTENSIFY, BUT SHOULD GRADUALLY STRENGTHEN INTO EARLY EVENING.
FARTHER EAST, THE WESTERN EXTENT OF LOW TO MID 60S SURFACE DEWPOINTS
EXISTS ACROSS FAR EASTERN CO, YIELDING MUCH MORE AMPLE MLCAPE. MOST
GUIDANCE SUGGESTS AT LEAST ONE STORM SHOULD BECOME SUSTAINED IN
SOUTHEAST CO OVER THE AR VALLEY AND COULD BE A LONGER-LASTING
SUPERCELL GIVEN THE ENVIRONMENT. OTHERWISE, THE HIGHER-BASED
CONVECTION TO THE WEST AND NORTHWEST WILL PROBABLY CONSIST OF
OUTFLOW-DOMINATED SUPERCELL STRUCTURES WITH A MIX OF SPORADIC LARGE
HAIL AND SEVERE GUSTS.
