   Concerning...Severe Thunderstorm Watch 361...

   Valid 032314Z - 040045Z

   The severe weather threat for Severe Thunderstorm Watch 361
   continues.

   SUMMARY...The threat for damaging wind and possibly a tornado will
   spread northeastward this evening.

   DISCUSSION...A QLCS has evolved across southeast IA into northeast
   MO, and will continue spreading northeastward into a moist and
   moderately unstable environment. A small bowing segment has evolved
   within the northern portion of the QLCS across southeast IA, where
   the orientation of the line has become more orthogonal to the
   deep-layer shear vectors. This section of the line may pose a
   locally greater threat of damaging wind through early evening as it
   moves into northwest IL. Low-level shear (as depicted on the KDVN
   VWP) is also sufficient to support some potential for a
   line-embedded tornado. 

   Farther south, the environment remains favorable along the southern
   portion of the QLCS, and a threat for damaging wind and possibly a
   brief tornado will eventually spread into west-central IL. Isolated
   hail will also be possible with the stronger embedded cells.
