AREAS AFFECTED...SERN MI

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 270048Z - 270115Z

ISOLATED STRONG TO SEVERE STORMS POSSIBLE...BUT WW NOT EXPECTED AT
THIS TIME.

REGIONAL RADARS INDICATED A BROKEN LINE OF STORMS EXTENDING FROM
SANILAC COUNTY WSWWD TO ALONG THE BORDER OF GRATIOT/CLINTON COUNTIES
IN SERN-SERN LOWER MI. THIS ACTIVITY IS MOVING SEWD INTO AN AIR
MASS THAT HAS BECOME MARGINALLY UNSTABLE WITH THE LOSS OF DAYTIME
HEATING.  DESPITE MARGINAL INSTABILITY AND WEAK LAPSE RATES OVER
THIS REGION...LOW LEVEL DIRECTIONAL SHEAR AND STRONG DEEP LAYER
SHEAR SUGGEST A FEW STORMS WILL BE CAPABLE OF ROTATING.  IN
ADDITION...VERY MOIST BOUNDARY LAYER WITH SMALL SURFACE DEWPOINT
DEPRESSIONS AND LOW LCLS SUGGEST A POTENTIAL FOR BRIEF TORNADO OR
TWO.  HOWEVER...MARGINAL INSTABILITY SHOULD TEND TO LIMIT COVERAGE
OF STRONG AND SEVERE STORM ACTIVITY.  THUS...WW IS NOT EXPECTED...
BUT CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED.
