Sep 29-30, 2011 Peak Wind Gusts

Strong west to northwest winds gusting to 45 to 55 mph affected south-central and southeast Wisconsin during the afternoon hours of September 29th into the overnight hours.   However, Green County experienced high wind conditions with sustained winds of 43 mph for one hour at the Monroe Airport, and there was a report of a gust of 68 mph just south of the city of Monroe.

A strengthening low pressure moving east through the upper Great Lakes region was responsible for the gusty winds.  Some scattered showers with small hail also occurred.   The showers were probably responsible for some of the higher gusts.

There were reports of scattered power outages due to broken tree branches knocking down power lines.  This is very typical of wind gusts in the range of 45 to 55 mph.

Below is a listing of some of the reports we received.
