   Areas affected...Extreme eastern IA into northern IL and extreme
   southern WI

   Concerning...Severe Thunderstorm Watch 361...

   Valid 040024Z - 040200Z

   The severe weather threat for Severe Thunderstorm Watch 361
   continues.

   SUMMARY...Threat for severe/damaging wind and line-embedded
   tornadoes will spread northeastward this evening.

   DISCUSSION...A storm cluster with embedded circulations remains
   intense early this evening near/south of Davenport, IA. Deep-layer
   shear vectors remain favorably orthogonal with this line segment,
   with stronger cores aloft indicating the presence of embedded
   supercells within this cluster. Favorably moist and sufficiently
   unstable downstream conditions favor maintenance of this system into
   a larger portion of northwest IL. A wind gust of 81 mph was recorded
   earlier in Burlington, IA, and wind gusts of 60-80 mph remain
   possible with this intense storm cluster. Low-level flow/shear is
   strengthening ahead of the system (as noted on the KILX VWP), and
   line-embedded tornadoes will continue to be possible, given the
   presence of embedded supercell structures.  

   The severe threat may eventually spread east of WW 361, and local
   expansion of the watch will continue to be possible with time this
   evening.
