...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE NORTH-CENTRAL HIGH
PLAINS...

...THERE IS A MRGL RISK OF SVR TSTMS FROM THE NORTHERN/CENTRAL HIGH
PLAINS TO THE MIDDLE MS VALLEY...

...THERE IS A MRGL RISK OF SVR TSTMS ACROSS THE SOUTHEAST STATES...

CORRECTED FOR WORDING

...SUMMARY...
SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS PORTIONS OF THE
NORTH-CENTRAL HIGH PLAINS ON THURSDAY...AND POSSIBLY PARTS OF THE
LOWER/MIDDLE MISSOURI RIVER VALLEY AND SOUTHEAST STATES AS WELL.

...NORTH-CENTRAL HIGH PLAINS TO THE MIDDLE/LOWER MO VALLEY...
THE LARGE-SCALE PATTERN WILL BECOME INCREASINGLY AMPLIFIED INTO
THURSDAY...HIGHLIGHTED BY A SOUTHWARD-DIGGING UPPER LOW OVER
CA/SOUTHWEST STATES AND AN AMPLIFYING UPPER RIDGE OVER THE
SOUTHERN/CENTRAL PLAINS. WHILE A RELATIVELY MOIST AIR MASS WILL
PERSIST ACROSS MUCH OF THE REGION NEAR A FRONTAL BOUNDARY AND EAST
OF THE ROCKIES FRONT RANGE...UPPER RIDGE-RELATED WARMING/CAPPING
ALOFT AND THE POTENTIAL FOR RESIDUAL MCS IMPACTS/OUTFLOW ACROSS THE
MIDDLE/LOWER MO VALLEY COMPLICATE THE FORECAST DETAILS.

STRONG/SEVERE THUNDERSTORM REDEVELOPMENT AND POTENTIAL MCS FORMATION
COULD OCCUR THURSDAY AFTERNOON/EVENING ACROSS PORTIONS OF THE LOWER
MO VALLEY/MIDDLE MS VALLEY VICINITY...BUT THE MOST PROBABLE SCENARIO
MAY BE FOR AT LEAST ISOLATED SEVERE THUNDERSTORMS TO DEVELOP
THURSDAY AFTERNOON/EARLY EVENING IN A NORTH-SOUTH CORRIDOR ACROSS
THE NORTH-CENTRAL HIGH PLAINS WITH AID OF MOIST/MODESTLY UNSTABLE
UPSLOPE FLOW. WHILE MODEST FORCING/CAPPING ARE POINTS OF
UNCERTAINTY...OTHER STRONG/SEVERE THUNDERSTORM DEVELOPMENT COULD
OCCUR THURSDAY EVENING ACROSS KS NEAR A SURFACE BOUNDARY AND TO THE
NORTHEAST OF A SURFACE TRIPLE POINT.

...SOUTHEAST STATES...
AS THE UPPER LOW CONTINUES TO DRIFT SLOWLY EAST-SOUTHEASTWARD...
ISOLATED STRONG TO SEVERE THUNDERSTORMS MAY BE POSSIBLE ACROSS
PORTIONS OF THE REGION MAINLY THURSDAY AFTERNOON/EARLY EVENING.
