   Concerning...Severe Thunderstorm Watch 425...

   Valid 101600Z - 101700Z

   The severe weather threat for Severe Thunderstorm Watch 425
   continues.

   SUMMARY...A swath of significant severe/damaging wind gusts appears
   likely across and to the east of the Des Moines metro area.

   DISCUSSION...Latest velocity data from the KDMX radar shows an
   impressive significant wind signature with the ongoing MCS, with
   80-115+ kt inbound velocities noted only 500-1000 ft AGL. These very
   likely severe winds will move across the Des Moines metro area
   shortly, and they will be capable of producing widespread,
   destructive damaging winds of 70-80+ mph as the MCS races eastward
   at 50-60 kt.
