Areas affected...Parts of Indiana/Ohio/southern Lower Michigan

Concerning...Severe Thunderstorm Watch 151...

Valid 202031Z - 202230Z

The severe weather threat for Severe Thunderstorm Watch 151
continues.

SUMMARY...Isolated severe risk continues in and near WW #151.

DISCUSSION...Latest radar loop shows several bands of storms moving
across southern Lower Michigan/Indiana/western Ohio at this time,
with a new band of storms developing along the immediate frontal
zone.  This band of storms -- now entering northwest portions of WW
#151 -- likely marks the back edge of severe risk, which will
gradually advance eastward across the watch over the next few hours.
 Meanwhile, risk for locally damaging winds and hail continues, as
an amply sheared and unstable warm sector remains in place in and
near the WW area.
