   Concerning...Severe Thunderstorm Watch 337...

   Valid 070824Z - 071030Z

   The severe weather threat for Severe Thunderstorm Watch 337
   continues.

   SUMMARY...A severe threat will likely continue for another hour or
   so across northeast Nebraska. As the line of storms approaches the
   Nebraska-Iowa state line, the threat is expected to become marginal.
   Wind damage and hail will be the primary threats. No new watch is
   expected downstream.

   DISCUSSION...The latest radar imagery shows a line of strong
   thunderstorms from far southeast South Dakota into northeast
   Nebraska. The line of storms is supported by a 30 to 40 kt low-level
   jet over the central Plains and by a minor shortwave trough moving
   through the northern Plains. Although a wind-damage and hail threat
   may continue for another hour or so, the line of storms is moving
   away from the low-level jet which is centered over western Nebraska.
   The line of storms has also shown some weakening characteristics
   including warming cloud tops on IR imagery. For this reason, the
   threat should become increasingly isolated, especially as the
   convection approaches the Nebraska-Iowa state line.
