Areas affected...Upper Midwest

Concerning...Severe Thunderstorm Watch 534...

Valid 150051Z - 150215Z

The severe weather threat for Severe Thunderstorm Watch 534
continues.

SUMMARY...Severe threat will spread across northern
Illinois/southern Wisconsin this evening.

DISCUSSION...Remnant MCV, from an early-day MCS, is moving
east-southeast across central IA. Latest radar/satellite imagery
suggests this long-lived feature is located northwest of CID. Over
the last hour or so, considerable amount of convection has
developed, possibly in response to this MCV. While a few supercells
are currently observed from southwest WI, arcing southwest along the
MS River through the middle portions of ww534, a new MCS may soon
evolve. This developing co*plex is expected to propagate toward
southern Lake MI with an attendant risk for hail/wind.
