   Areas affected...portions of southeastern Nebraska into central Iowa

   Concerning...Tornado Watch 669...

   Valid 150020Z - 150115Z

   The severe weather threat for Tornado Watch 669 continues.

   SUMMARY...A few severe gusts and a tornado remain possible over the
   next few hours. The best chance for any severe will be with a
   thunderstorm cluster traversing a differential heating boundary over
   the next 1-2 hours.

   DISCUSSION...A loosely organized line of thunderstorms is crossing
   the NE/IA border with a history of severe gusts. These storms will
   continue to propagate eastward into a highly sheared, destabilizing
   airmass, accompanied by a severe gust threat. The best chance for
   severe gusts, including any additional 75+ mph gusts or a brief
   tornado will be with the embedded thunderstorm cluster that is
   currently traversing a differential heating boundary.
