Areas affected...eastern/southern Lower MI to northeast IN and
northwest OH

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

Valid 301646Z - 301845Z

Probability of Watch Issuance...5 percent

SUMMARY...A broken line of thunderstorms may pose a risk for
localized damaging winds and small hail through late afternoon.

DISCUSSION...Along a weak cold front, a broken line of thunderstorms
is bisecting Lower MI into far northern IN. Airmass immediately
downstream has warmed into the low to mid 80s, with heating slowed
farther east in the wake of an MCV over north-central/northeast OH.
Moist low-levels amid weak mid/upper-level rates, combined with
generally weak to modest low/mid-level shear, should serve to
mitigate the overall severe threat. Small hail production is
possible with some speed shear in the upper portion of the buoyancy
profile. Locally strong gusts in wet microbursts should be the main
hazard, but that will likely be modulated by the sub-optimal
thermodynamic environment.
