   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.
