NWS STORM PREDICTION CENTER NORMAN OK
0215 PM CDT FRI APR 03 2026
AREAS AFFECTED...EASTERN TEXAS SOUTH PLAINS INTO CENTRAL OKLAHOMA
AND SOUTHEAST KANSAS
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 031915Z - 032115Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...A WATCH IS LIKELY THIS AFTERNOON AS INITIAL SUPERCELLS
DEVELOP ALONG THE COLD FRONT. LARGE/VERY-LARGE HAIL AND SEVERE WINDS
WILL BE THE MAIN HAZARDS. THE TORNADO THREAT IS CONDITIONAL ON
MAINTAINING A DISCRETE STORM MODE INTO EARLY EVENING.
DISCUSSION...THE OBSERVED 18Z LMN SOUNDING SHOWED A FIRM CAP AT
ABOUT 800 MB. MODIFYING THIS SOUNDING FOR NEARBY CURRENT SURFACE
OBSERVATIONS WOULD SUGGEST THAT THIS CAP IS ERODING, WHICH IS
SUPPORTED BY VISIBLE SATELLITE/REGIONAL RADARS SHOWING A FEW DEEPER
SHOWERS/THUNDERSTORMS OVER THE LAST HOUR. 30-40 KTS OF EFFECTIVE
SHEAR WILL PROMOTE INITIAL SUPERCELLS CAPABLE OF LARGE/VERY-LARGE
HAIL AS WELL WELL AS SEVERE WIND GUSTS. GIVEN THE SHEAR VECTOR
MOSTLY PARALLEL TO THE COLD FRONT AS WELL AS THE STRONGER LINEAR
FORCING, INITIAL ACTIVITY IS EXPECTED TO CONGEAL SOMEWHAT QUICKLY.
THE TORNADO THREAT IS LESS CLEAR ON ACCOUNT OF THE INITIALLY WEAK
LOW-LEVEL SHEAR AS WELL AS THE TRANSITION TO A LINEAR MODE. HOWEVER,
A WEAK SURFACE LOW IN NORTHWEST TEXAS INTO SOUTHWEST OKLAHOMA COULD
BE A ZONE OF GREATER DISCRETE STORM POTENTIAL. SHOULD THOSE STORMS
REMAIN DISCRETE INTO THE EVENING, THERE WILL BE AN INCREASE IN
LOW-LEVEL SHEAR AND, ACCORDINGLY, A GREATER TORNADO RISK. THIS
SCENARIO IS LOW CONFIDENCE, THOUGH.
