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 >

 

 
 
Overview
  • Numerous rain showers, regularly mixed with graupel and at times snow, moved over northern Illinois and northwestern Indiana during the late afternoon and evening of March 25, 2022. The showers are called squalls, and develop in the same way as springtime thunderstorms. They produce brief but intense precipitation rates and winds, some of which can be damaging. 
  • Wind gusts of 50 to 60 mph were observed across northern Illinois and northwest Indiana within and outside of squalls. The peak wind gust was 72 mph in Sugar Grove, associated with a particularly intense squall.
