DAY 3 CONVECTIVE OUTLOOK

VALID 311200Z - 011200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE UPPER MS VALLEY TO THE
CNTRL PLAINS...

...SUMMARY...
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A COLD FRONT
FROM MINNESOTA...SOUTHWEST INTO KANSAS.  ISOLATED LARGE HAIL AND
STRONG WINDS MAY BE OBSERVED WITH THIS ACTIVITY.

...UPPER MS VALLEY TO CNTRL PLAINS...

SIGNIFICANT SHORT-WAVE TROUGH WILL MIGRATE INTO THE HIGH PLAINS
SUNDAY AFTERNOON WITH MODEST WSWLY FLOW FORECAST TO OVERSPREAD THE
IMMEDIATE FRONTAL ZONE AS FAR SOUTH AS KANSAS...AND ALONG THE
DRYLINE ACROSS THE TX PANHANDLE.  LARGE SCALE PATTERN IS EXPECTED TO
BE SUBSTANTIALLY DIFLUENT ALOFT WHICH SHOULD ENCOURAGE QUITE A FEW
STORMS TO EVOLVE ALONG WIND SHIFT BY LATE AFTERNOON AS CINH WEAKENS.

THUNDERSTORMS MAY BE ONGOING AT THE START OF THE PERIOD ACROSS PARTS
OF ND/NRN MN BUT THIS CONVECTION SHOULD BE ELEVATED AND POSSIBLY
POST-FRONTAL BEFORE LIFTING NORTH OF THE INTERNATIONAL BORDER.  OF
MORE CONCERN WILL BE TSTMS THAT DEVELOP ALONG THE FRONT BY MID-LATE
AFTERNOON...INITIALLY ACROSS MN...THEN PROGRESSIVELY SW ALONG THE
WIND SHIFT ACROSS NEB INTO KS WHERE TEMPERATURES SHOULD SOAR INTO
THE MID 90S.  DEEP LAYER SHEAR IS FORECAST TO BE SUPPORTIVE OF AT
LEAST ORGANIZED MULTI-CELL CLUSTERS AND A FEW SUPERCELLS MAY
ULTIMATELY DEVELOP TOWARD EVENING WHEN SHEAR/LLJ
INCREASES...ESPECIALLY ACROSS THE CNTRL PLAINS.  LARGE HAIL AND
STRONG WINDS ARE THE PRIMARY THREATS WITH NEAR-FRONTAL CONVECTION.
SEVERE THREAT COULD LINGER WELL INTO THE EVENING HOURS AS SHORT WAVE
EJECTS TOWARD THE MID MO VALLEY.
