   Concerning...Severe Thunderstorm Watch 425...

   Valid 101445Z - 101615Z

   The severe weather threat for Severe Thunderstorm Watch 425
   continues.

   SUMMARY...The greatest severe/damaging wind threat will focus over
   central Iowa, including the Des Moines metro area, over the next
   hour or two.

   DISCUSSION...Numerous measured severe wind gusts have been observed
   across eastern NE and western IA over the past hour in association
   with a small MCS. As this bow moves quickly eastward (around 45-50
   kt) into central IA this morning, it will encounter an increasingly
   unstable airmass. A focused corridor of severe/damaging winds of
   60-70+ mph appears likely given recent radar trends, with the
   development of a real-inflow jet and strong inbound velocities noted
   on the KDMX radar. This corridor will likely include the Des Moines
   metro area, with extrapolation of current storm motion suggesting
   arrival in this area around 16Z (11 AM CDT).
