   Areas affected...East-central NE...Southwest IA

   Concerning...Severe Thunderstorm Watch 381...

   Valid 300224Z - 300330Z

   The severe weather threat for Severe Thunderstorm Watch 381
   continues.

   SUMMARY...Strong storms will spread across southeastern portions of
   WW381.

   DISCUSSION...Convective outflow has surged 10-15mi ahead of trailing
   convection along the southwestern flank of IA MCS. Latest radar data
   continues to suggest large hail accompanies two significant updrafts
   west of the Missouri River near OMA. This activity appears to be
   partly supported by a notable short-wave trough that currently
   extends along the SD/MN border into extreme eastern NE. As the
   trough shifts east the back edge of strong convection should shift
   east into southwestern IA where gradual weakening is expected over
   the next few hours.
