Areas affected...southern Lower MI...eastern IN...western OH...far
northern KY

Concerning...Severe potential...Tornado Watch likely=20

Valid 072033Z - 072200Z

Probability of Watch Issuance...80 percent

SUMMARY...As supercells spread quickly east-northeast from southern
Lower MI and northwest IN, an additional tornado watch/watches will
be needed prior to 22Z. This may also include a combined/separate
watch farther south in eastern IN/western OH ahead of supercells
intensifying over the Wabash Valley.

DISCUSSION...As mentioned in MCD 0679, an increasingly favorable
setup for supercells, a couple of which may be long-tracked, is
underway across northwest IN to the Wabash Valley. The northern
storms may being to outpace the rapid boundary-layer
warming/moistening that is occurring across northeast IN and
northwest OH into southern Lower MI. Nevertheless, the intense
mid-level jet will likely foster sustained supercells even as they
become slightly elevated towards southeast Lower MI. With backed
low-level flow and ample low-level shear (per IWX VWP data), the
tornado threat will remain prominent with any supercells along and
south of the surface warm front. A couple strong tornadoes are
possible.
