   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 complex is expected to propagate toward
   southern Lake MI with an attendant risk for hail/wind.
