Areas affected...far eastern Wisconsin...northern Michigan

Concerning...Severe potential...Watch possible=20

Valid 232332Z - 240030Z

Probability of Watch Issuance...40 percent

SUMMARY...Strong to severe wind threat may continue across northern
Michigan.

DISCUSSION...A line of thunderstorms now moving through the Green
Bay area has produced reports of wind damage and measured gusts
60-65 mph. This line will move eastward across Lake Michigan and
eventually into portions of northern Michigan and the upper Michigan
Peninsula. It is uncertain if this line will maintain intensity,
given the decrease in instability with eastward extent across this
region and loss of daytime heating. None the less, a gradient of
MLCAPE around 500-1500 J/kg remains in place along with deep layer
shear around 30-35 kts. The progression of this line will be
monitored but a watch is not anticipated at this time.
