   Areas affected...east-central Missouri into far western Illinois

   Concerning...Severe Thunderstorm Watch 35...

   Valid 140044Z - 140245Z

   The severe weather threat for Severe Thunderstorm Watch 35
   continues.

   SUMMARY...Large hail and damaging wind risk continues in WW35.

   DISCUSSION...Recent storm activity across the south side of the St.
   Louis metro this evening has produced instances of large hail up to
   1.75 in. Additional storm development is occurring near the surface
   warm font. Surface objective analysis continues to indicate around
   1000-1500 J/kg of MLCAPE overlapping 40-45 kts of deep layer shear
   and steep low to mid-level lapse rates. This will continue to
   support potential for elevated supercells capable of large hail and
   damaging wind through the next few hours this evening.
