Cold Front Dropping South Across the Western U.S.; Watching Threat for Tornadoes and Flooding in the South

A cold front will push south across the Western U.S. into Tuesday with mountain snow and areas of gusty to high winds. An area of low pressure will form along this front on Tuesday and bring a potential for severe thunderstorms with tornadoes and excessive rainfall in the lower to mid Mississippi River Valley. To the north, heavy snow is possible in parts of the upper Midwest. Read More >

A major weather system impacted the middle of the country during April 13-15.  For northern Illinois and northwest Indiana, this brought gusty winds, rain, and for far northern Illinois some snow and ice.  The effects of the snow and ice combined with the winds led to power outages near the Wisconsin line.  In addition, the strong winds from the northeast gusting over 40 mph brought high waves to the western and southern shores of Lake Michigan on Saturday, April 14.  These waves brought flooding to some lakeshore areas, including parts of the Chicago shore such as the bike path.
