AREAS AFFECTED...NRN LOWER MI

CONCERNING...SEVERE THUNDERSTORM WATCH 640...

VALID 250221Z - 250345Z

THE THREAT FOR ISOLATED DAMAGING WIND GUSTS IS EXPECTED TO PERSIST
ANOTHER HOUR OR TWO WITH CLUSTERS OF STORMS DEVELOPING OVER THE NRN
TIP OF LOWER MI. CONFIDENCE IS LOW THAT ADDITIONAL STRONG STORMS
WILL DEVELOP FARTHER S.  

SMALL CLUSTER OF STORMS CONTINUES MOVING EWD THROUGH EXTREME NRN
LOWER MI. THE ATMOSPHERE REMAINS MODERATELY UNSTABLE. HOWEVER...SWD
EXTENTION OF OUTFLOW BOUNDARY REMAINS LARGELY FREE OF THUNDERSTORMS.
THE ORIENTATION OF THE WLY LOW LEVEL JET RELATIVE TO THE EWD MOVING
OUTFLOW BOUNDARY APPEARS TO BE LIMITING DEEP LAYER CONVERGENCE. THIS
ALONG WITH THE STABILIZING BOUNDARY LAYER LOWERS CONFIDENCE THAT
ADDITIONAL STRONG STORMS WILL DEVELOP FARTHER S.
