DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK

VALID 291200Z - 301200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR FAR SOUTHEAST
MINNESOTA INTO THE WESTERN UPPER PENINSULA OF MICHIGAN....
..SUMMARY
ISOLATED TO SCATTERED STRONG TO SEVERE STORMS ARE POSSIBLE FROM THE
CENTRAL HIGH PLAINS TO THE NORTHERN GREAT LAKES ON SUNDAY.
..SYNOPSIS
A MID-LEVEL TROUGH WILL AMPLIFY ACROSS THE NORTHERN PLAINS ON
SUNDAY. AT THE SURFACE, A COLD FRONT WILL MOVE ACROSS THE UPPER
MIDWEST TO NEAR NORTHERN LOWER MICHIGAN TO THE CENTRAL PLAINS BY 12Z
MONDAY.
..CENTRAL PLAINS TO THE UPPER MIDWEST
VERY STRONG TO EXTREME INSTABILITY IS FORECAST TO DEVELOP AHEAD OF A
COLD FRONT FROM THE CENTRAL PLAINS TO WISCONSIN. STORMS ARE EXPECTED
TO DEVELOP ALONG THIS FRONT DURING THE AFTERNOON TO EVENING ON
SUNDAY. SHEAR WILL BE MOSTLY WEAK ALONG THE FRONT WHICH MAY LIMIT
STORM ORGANIZATION. HOWEVER, WHERE STRONGER MID-LEVEL FLOW IS
PRESENT (CENTRAL AND NORTHERN WISCONSIN INTO THE WESTERN UP OF
MICHIGAN), MORE ORGANIZED STORMS ARE EXPECTED, INCLUDING THE
POTENTIAL FOR SUPERCELLS. THESE STORMS WILL POSE A THREAT FOR SEVERE
WIND GUSTS AND LARGE HAIL, AND PERHAPS A TORNADO.
FARTHER SOUTH AND WEST ALONG THE FRONT, WEAKER SHEAR WILL BE
PRESENT. HOWEVER, VERY STRONG HEATING AND STEEP LAPSE RATES WILL
SUPPORT SOME SEVERE WIND THREAT AS STORMS DEVELOP ALONG THE UNCAPPED
FRONT DURING THE AFTERNOON/EVENING ON SUNDAY.
