June 25-26, 2021: Tornadoes and Flash Flooding

Overview

An active late June weather pattern resulted in several consecutive days of heavy rainfall and thunderstorms across northern Illinois and northwest Indiana. On June 25th, these storms produced a brief multi-vortex EF-1 tornado near Danforth, IL, along with heavy rainfall south of the Kankakee River Valley. On June 26th, storms produced three additional EF-0 tornadoes in the area, and heavy rainfall resulted in flash flooding in the Chicago metro and areas farther south.

Fast Facts:

On the evening of June 25th, storms moved into areas along and south of the Kankakee River Valley. One of these storms went on to produce a brief multi-vortex EF-1 tornado near Danforth, IL in Iroquois County.

Additional thunderstorms developed during the late morning and afternoon of June 26th. These storms went on to produce 3 EF-0 tornadoes: one in Dyer and Schererville (IN), one in Crete (IL), and another in Chatsworth (IL). Some spotty wind damage was also reported in northwest Indiana as these storms rolled through.

Strong rotation within a storm over the city of Chicago prompted a Tornado Warning to be issued for the city, which included Downtown Chicago. This was the first Tornado Warning issued for Downtown Chicago in just over 11 years, with the last one being issued for Downtown on June 23rd, 2010. Fortunately, this storm did not end up producing any tornadoes.

In addition to tornadoes, flash flooding occurred on the 26th in many locations where heavy rainfall-producing thunderstorms "trained" over the same locations, resulting in several inches of rain in the span of just a few hours.
