0805 PM CDT SAT APR 25 2026
AREAS AFFECTED...FAR SOUTHERN KANSAS INTO NORTHWEST OKLAHOMA
CONCERNING...SEVERE THUNDERSTORM WATCH 143...
VALID 260105Z - 260230Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 143
CONTINUES.
SUMMARY...THE NEAR-TERM SEVERE THREAT APPEARS TO BE DIMINISHING
ACROSS FAR SOUTHERN KANSAS AND NORTHWEST OKLAHOMA. CONVECTIVE TRENDS
ARE BEING MONITORED TO DETERMINE IF A TEMPORAL WATCH EXTENSION MAY
BE NEEDED FOR SOUTHERN PORTIONS OF WW 134.
DISCUSSION...A SUPERCELL MOVING SOUTHEASTWARD ACROSS SOUTHERN KS HAS
SHOWN SIGNIFICANT SIGNS OF WEAKENING OVER THE PAST 30 MINUTES. WHILE
ATTEMPTS AT ADDITIONAL CONVECTIVE INITIATION NOTED EARLY ACROSS
NORTHWEST OK, THE ONSET OF NOCTURNAL COOLING AND INCREASING
INHIBITION HAS DRASTICALLY REDUCED THE POTENTIAL FOR ADDITIONAL
THUNDERSTORM DEVELOPMENT ACROSS WEST-CENTRAL TO NORTHWEST OK. THESE
TRENDS SUGGEST THAT THE SEVERE THREAT FOR SOUTHERN PORTIONS OF WW
134 IS QUICKLY WANING. HOWEVER, WEAK CONVECTION CONTINUES TO DEVELOP
ALONG AN OUTFLOW BOUNDARY ALONG AND SOUTH OF HIGHWAY 54 NEAR PRATT,
KS. GIVEN LOCALLY STRONGER FORCING FOR ASCENT THAT CAN COMPENSATE
FOR INCREASING INHIBITION AND AN OTHERWISE FAVORABLE THERMODYNAMIC
AND KINEMATIC ENVIRONMENT, IT REMAINS PLAUSIBLE THAT THIS ACTIVITY
COULD INTENSIFY AND POSE A SEVERE HAIL/WIND THREAT DOWNSTREAM INTO
FAR NORTHWEST OK IN THE COMING HOURS. CONFIDENCE IN THIS SCENARIO IS
LOW, BUT CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED TO
DETERMINE IF A TEMPORAL EXTENSION OF PORTIONS OF WW 134 WILL BE
REQUIRED AFTER THE 02 UTC EXPIRATION TIME.
