   Areas affected...parts of central Illinois

   Concerning...Tornado Watch 32...

   Valid 110301Z - 110430Z

   The severe weather threat for Tornado Watch 32 continues.

   SUMMARY...Severe storms remain likely this evening across WW32. A
   few tornadoes, hail and an increasing damaging wind threat are
   expected.

   DISCUSSION...Across parts of far eastern MO/IA into central IL,
   several clusters of strong to severe storms are ongoing as of 0300
   UTC. A mixed convective mode is present, and expected to continue,
   with semi-discrete supercells ongoing over the western portions of
   the watch area. These storms are moving into a very strongly sheared
   air mass that remains moderately unstable (LSX VAD 0-1km SRH 500+
   m2/s2). This will continue to support supercells and linear
   structures capable of all hazards. With time, upscale growth into
   one or more linear clusters appears likely. Damaging gusts and a few
   tornadoes are possible.
