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 >

On December 31, 1988, the Chicago Bears faced off with the Philadelphia Eagles at Soldier Field in downtown Chicago.  Midway through the second quarter of the game, a relatively small, but very dense area of fog that had been moving south down Lake Michigan moved onshore, quickly dropping visibility to between 10 and 20 yards for the remainder of the game.  The fog proved to be a particular challenge for players and spectators alike, with both teams being forced to a running game as receivers could no longer see the football, and fans and television announcers finding it nearly impossible to see the action on the field.  The end of the game was a happy one for fans of the Bears, however, as they prevailed 20-12.

Below are hourly observations from the former Meigs Field, now Northerly Island.  Note that visibilities had been around 3 miles during the morning with a west-southwest wind, but by about 10 minutes after noon, winds had shifted to the southeast, very dense fog rolled in off Lake Michigan, and visibility only went down from there!
