VALID 260100Z - 261200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PARTS OF
THE TEXAS PANHANDLE...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER NORTHWEST
WISCONSIN...
..SUMMARY
SEVERE THUNDERSTORMS REMAIN POSSIBLE THIS EVENING ACROSS PARTS OF
THE CENTRAL/SOUTHERN PLAINS, AND ALSO ACROSS PORTIONS OF THE UPPER
MIDWEST. SEVERE WIND GUSTS AND ISOLATED LARGE HAIL ARE THE PRIMARY
HAZARDS.
..SOUTHERN/CENTRAL HIGH PLAINS
A STORM CLUSTER IS MOVING SOUTHEASTWARD ACROSS THE TX/OK PANHANDLES
THIS EVENING. A SHORT-TERM THREAT FOR STRONG TO SEVERE GUSTS WILL
PERSIST THROUGH THE EVENING WITH THIS CLUSTER. THE EVOLUTION OF THIS
CLUSTER AS IT MOVES INTO A REGION INFLUENCED BY WESTWARD-MOVING
OUTFLOW IS UNCLEAR. COOLER TEMPERATURES AND WEAKER LOW-LEVEL LAPSE
RATES ARE OBSERVED WITHIN THIS OUTFLOW, THOUGH RICHER LOW-LEVEL
MOISTURE AND STRONGER MUCAPE ALSO NOTED, WHICH MAY HELP TO SUSTAIN
THE ONGOING CLUSTER AND AN ATTENDANT SEVERE-WIND THREAT THROUGH THE
EVENING.
FARTHER NORTH, WIDELY SCATTERED STRONG TO SEVERE STORMS ARE ONGOING
ACROSS PARTS OF THE CENTRAL HIGH PLAINS. MODERATE BUOYANCY AND
EFFECTIVE SHEAR OF 30-40 KT WILL CONTINUE TO SUPPORT A THREAT OF
ISOLATED HAIL AND LOCALIZED STRONG TO SEVERE GUSTS THROUGH DUSK.
INCREASING CINH SHOULD EVENTUALLY LEAD TO A WEAKENING TREND LATER
TONIGHT, THOUGH ANY STORM CLUSTERING THIS EVENING COULD LEAD TO A
LONGER DURATION OF LOCALIZED SEVERE-WIND POTENTIAL. SEE MCD 2132 FOR
MORE INFORMATION REGARDING THE SHORT-TERM THREAT IN THIS AREA.
..PARTS OF WI/UPPER MI
OCCASIONAL STRONG TO SEVERE STORMS HAVE BEEN NOTED WITHIN A STORM
CLUSTER ACROSS NORTHWEST WI THIS EVENING. MLCAPE OF 1000-2000 J/KG
AND 30-40 KT OF EFFECTIVE SHEAR LARGELY ORTHOGONAL TO THE SURFACE
FRONT/TROUGH WILL CONTINUE TO SUPPORT SUPERCELL POTENTIAL THROUGH
DUSK, BEFORE A GRADUAL WEAKENING TREND IS EXPECTED. SEE MCD 2133 AND
WW 626 FOR MORE INFORMATION.
