Mesoscale Discussion 1013
NWS Storm Prediction Center Norman OK
0639 PM CDT Fri Jun 26 2020

Areas affected...Southwest Michigan...northern Indiana...and far
northwest Ohio

Concerning...Severe potential...Watch needed soon 

Valid 262339Z - 270045Z

Probability of Watch Issuance...95 percent

SUMMARY...A severe thunderstorm watch will be issued shortly across
southwest Michigan, northern Indiana, and far northwest Ohio.

DISCUSSION...Multiple clusters of storms across northern Illinois
and southern Wisconsin have recently started to congeal across
western Lake Michigan and northern Illinois. The severe-weather
threat (especially damaging winds) is expected to increase as these
clusters continue to organize. In addition, a tornado or two is
possible, especially in far northern Indiana and southern Michigan
where surface winds remain more backed near a warm front. However,
relatively weak surface winds will be the primary limiting factor to
a greater tornado threat. 

A severe thunderstorm watch will be issued by 00Z across this
region.
