   Areas affected...portions of eastern Iowa

   Concerning...Tornado Watch 497...

   Valid 022309Z - 030015Z

   The severe weather threat for Tornado Watch 497 continues.

   SUMMARY...A focused corridor of 60-85 mph wind gusts is expected
   with a bowing line segment across eastern IA.

   DISCUSSION...A QLCS continues to move across eastern IA, with a
   pronounced line-end mesovortex currently located over Johnson
   County, IA, tracking eastward. Immediately south of the mesovortex
   is a rear-inflow jet, where a measured 81 mph wind gust was recently
   reported and where a tornado was also reported. The current
   expectation is that this coupled mesovortex/rear-inflow jet
   structure will progress within the QLCS for at least the next hour
   or two, accompanied by a narrow but focused swath of severe gusts in
   the 60-85 mph range.
