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

Along and north of a slow moving warm front, storms continued to regenerate and train over portions of north central and northeast Illinois, generally along and near the I-88 and U.S. Highway 30 corridors.  The environment was favorable for locally heavy rainfall with any storms and giving the training and slow movement, isolated flooding occurred, including flash flooding in Lee County along U.S. Highway 30.  A flash flood warning was in effect.
