Areas affected...portions of Michigan

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

Valid 091817Z - 091945Z

Probability of Watch Issuance...60 percent

SUMMARY...Thunderstorms capable of damaging wind and hail to
increase through the afternoon.

DISCUSSION...Thunderstorms have been increasing in coverage across
Lake Michigan as forcing for ascent increases with an upper-level
wave approaching. Across the Michigan peninsula, cumulus is
increasing as well. Daytime heating has yielded MLCAPE around
250-500 J/kg. Enhanced flow aloft with the wave and steep lapse
rates will support potential for damaging winds and some instances
of severe hail. This area is being monitored for a potential watch
this afternoon.
