Areas affected...north-central Lower MI

Concerning...Severe potential...Watch unlikely=20

Valid 222020Z - 222115Z

Probability of Watch Issuance...20 percent

SUMMARY...The potential for a brief tornado and/or localized 50-65
mph gust will focus in a mesoscale area northwest of Saginaw Bay
over the next 1-2 hours.

DISCUSSION...A supercell has developed on the southern end of a band
of low-topped convection moving across northern Lower MI. Lightning
was recently observed in the past 15 minutes as the storm moves east
along a west-east oriented stationary front. Along and south of the
boundary, surface dewpoints are in the 70-72 deg F range. Ample
deep-layer shear and adequate buoyancy (500-1000 J/kg MLCAPE) will
seemingly support a continuation and maintenance of this storm as it
moves east. An isolated risk for a 50-65 mph gust and perhaps a
brief tornado are possible with this storm.
