Heavy Rain Continues in Florida; Cold Front Brings Thunderstorms and Showers to Central US

Scattered areas of heavy rain continue to produce isolated flash flooding across the Florida peninsula. Anomalous moisture will combine with a cold front and will bring heavy rain and scattered flash flooding across the Mid-South, Ohio and Tennessee Valleys today and Tuesday. Above average temperatures will continue to be found ahead of the cold front from the Midwest to the Northeast. Read More >

Overview

Wind gusts frequently reached 50 to 55 mph for much of northern Illinois and northwest Indiana on Sunday, November 15.

The peak wind gust was 69 mph at Chicago Midway Airport a little before noon, which was also measured at a nearby NWS Cooperative Observer location. This appeared to be a localized burst of higher gusts.

These winds were a result of a rapidly strengthening weather system moving from the Great Lakes into southeast Canada.

This continued the tempo of a windy autumn across the region, as shown in Chicago stats to the right.
