Areas affected...Indiana and southern Lower Michigan

Concerning...Severe Thunderstorm Watch 59...

Valid 200048Z - 200215Z

The severe weather threat for Severe Thunderstorm Watch 59
continues.

SUMMARY...Local risk for damaging wind gusts continues.

DISCUSSION...Latest radar loop shows a broken -- and gradually
weakening -- band of pre-frontal storms moving eastward across
central and northern Indiana.  While more vigorous cells within this
band persist farther south -- into portions of Tornado Watch 58
where slightly greater surface dewpoints (low to mid 50s) exist, the
prior, limited tornado risk over central and northern Indiana has
further diminished.  While a brief spin-up is still possible, the
predominant severe risk will remain locally damaging wind gusts.  In
the wake of the initial band, a second band of frontal convection
near the Illinois/Indiana border will reach western fringes of WW 59
over the next hour or so -- which may bring an additional chance for
wind gusts in excess of severe levels locally.  Overall though, a
gradual/nocturnal decrease in storm intensity within both of the
aforementioned bands will continue over the next few hours.
