...THERE IS A SLGT RISK OF SVR TSTMS ACROSS MUCH OF OK/KS INTO
WESTERN/NORTHERN MO AND SOUTHEAST NEB/SOUTHERN IA...
...OK/KS INTO THE MISSOURI VALLEY...
SEVERE STORMS CONTINUE TO DEVELOP ACROSS SOUTHWEST/WEST CENTRAL OK
AT THIS TIME. DOWNSTREAM OF THE UPPER TROUGH SHIFTING EASTWARD
ACROSS THE CENTRAL/SOUTHERN ROCKIES TONIGHT...A QUICKLY INCREASING
SOUTHERLY LOW LEVEL JET/MOISTURE TRANSPORT REGIME IS LIKELY TO
MAINTAIN THESE STORMS INTO NORTHERN OK/SOUTHERN KS THE REMAINDER OF
THE EVENING. AS EVIDENCED BY THE 00Z OBSERVED RAOB FROM NORMAN...THE
THERMODYNAMIC AND KINEMATIC ENVIRONMENT WILL REMAIN FAVORABLE FOR
SUPERCELLS...AND THUS POTENTIAL FOR LARGE HAIL AND LOCALLY-DAMAGING
WINDS...ALONG WITH A TORNADO THREAT MAINLY THE NEXT SEVERAL HOURS.
FARTHER NORTH...STORMS ARE EXPECTED TO BECOME MORE WIDESPREAD ACROSS
CENTRAL/EASTERN KS...AND THEN EAST-NORTHEASTWARD WITH TIME INTO
PORTIONS OF EASTERN NEB/MUCH OF MO/SOUTHERN IA/WESTERN IL. MOST OF
THIS CONVECTION SHOULD REMAIN ELEVATED WITH LARGE HAIL AS THE
PRIMARY HAZARD.
...LA/EAST TX...
PERSISTENT CLUSTER OF STRONG/ISOLATED SEVERE STORMS CONTINUES TO
SHIFT EASTWARD ACROSS CENTRAL LA EARLY THIS EVENING. A MARGINAL
HAIL/WIND GUST POTENTIAL MAY CONTINUE THE NEXT FEW HOURS...HOWEVER
THE OVERALL THREAT SHOULD CONTINUE TO DIMINISH WITH LOSS OF DAYTIME
HEATING.
...SOUTHWEST/WEST CENTRAL TX...
EARLIER ISOLATED STORMS THAT DEVELOPED ACROSS SOUTHWEST TX NEAR THE
BIG BEND HAVE WANED WITH LOSS OF DAYTIME HEATING. HOWEVER...WITH THE
DRYLINE LIKELY TO RETREAT THIS EVENING ACROSS WEST TX WITH ONSET OF
LARGE SCALE HEIGHT FALLS...A RENEWED BOUT OF THUNDERSTORMS WITH AN
ISOLATED SEVERE RISK COULD DEVELOP BY DAYBREAK EARLY MONDAY ACROSS
PORTIONS OF WEST CENTRAL/SOUTHWEST TX.
