   Concerning...Severe Thunderstorm Watch 460...

   Valid 252224Z - 260000Z

   The severe weather threat for Severe Thunderstorm Watch 460
   continues.

   SUMMARY...Strong thunderstorms will persist with a severe gust
   threat over the next few hours, and a couple instances of severe
   hail cannot be ruled out.

   DISCUSSION...Several strong thunderstorms continue to consolidate
   along a frontal boundary over NE into IA. While merging their cold
   pools, several of these storms have become outflow dominant, given
   that the stronger (i.e. 40 kts) effective bulk shear is lagging in
   the post-frontal boundary airmass. Storms should remain loosely
   organized along the frontal boundary, where 2500 J/kg MLCAPE will
   support a continued risk for some severe gusts and perhaps a couple
   instances of hail over the next few hours.
