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.
