   Areas affected...Parts of eastern NE into western IA

   Concerning...Severe Thunderstorm Watch 434...

   Valid 182251Z - 190015Z

   The severe weather threat for Severe Thunderstorm Watch 434
   continues.

   SUMMARY...The threat for severe gusts and isolated hail will
   continue into this evening.

   DISCUSSION...An extensive thunderstorm band is ongoing from
   northwest IA into eastern NE. There has been a tendency for these
   storms to be slightly anafrontal, due to generally front-parallel
   deep-layer flow and only marginal deep-layer shear. However, a few
   embedded clusters have begun to accelerate eastward and keep pace
   with the front, which could result in an increasing threat of strong
   to severe gusts as storms approach the Omaha/Lincoln areas and move
   into a larger portion of northwest IA. Otherwise, moderate to strong
   buoyancy will support potential for isolated hail with the strongest
   embedded cells.
