...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 LOWER MO VALLEY/MIDWEST...

...SUMMARY...
ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE ON FRIDAY ACROSS THE
NORTH-CENTRAL HIGH PLAINS...AND POSSIBLY INTO PARTS OF THE LOWER
MISSOURI RIVER VALLEY AND MIDWEST.

...NORTHERN/CENTRAL HIGH PLAINS...
WHILE THE UPPER RIDGE WILL REMAIN PROMINENT OVER THE PLAINS AND
MID-LEVEL TEMPERATURES WILL BE RELATIVELY WARM...MOIST LOW-LEVEL
UPSLOPE TRAJECTORIES MAY ALLOW FOR ISOLATED SEVERE THUNDERSTORMS TO
DEVELOP ACROSS THE CO/WY FRONT RANGE VICINITY AND POSSIBLY SOUTHEAST
MT INTO THE IMMEDIATELY ADJACENT HIGH PLAINS FRIDAY
AFTERNOON/EVENING. BOUTS OF SEVERE HAIL WOULD LIKELY BE THE MAIN
RISK.

...LOWER MO VALLEY/MIDWEST...
THUNDERSTORMS MAY DIURNALLY PERSIST/RE-INTENSIFY ACROSS THE REGION
INTO FRIDAY AFTERNOON WITHIN A MOIST/UNSTABLE AIR MASS TO THE SOUTH
OF A SOUTH/SOUTHEASTWARD-MOVING FRONT. IF SO...LOCALLY DAMAGING
WINDS/SOME HAIL MAY BE POSSIBLE.

...PORTIONS OF AZ/UT...
WITH THE CLOSED UPPER LOW EXPECTED TO BEGIN SHIFTING EASTWARD OVER
THE SOUTHWEST STATES ON FRIDAY...INCREASING FORCING FOR
ASCENT/PIVOTING UPPER-LEVEL JET AND RELATED STRONG VERTICAL SHEAR
WILL LIKELY OVERSPREAD THE REGION. WHILE MARGINAL MOISTURE/BUOYANCY
SHOULD BE LIMITING FACTORS...A FEW STRONGER STORMS CAPABLE OF
HAIL/WIND MAY BE POSSIBLE. THE REGION WILL BE REEVALUATED FOR LOW
SEVERE PROBABILITIES IN FUTURE OUTLOOKS.
