NWS said brief EF-1 tornadoes landed late Monday near Earlville, about 80 miles southwest of Chicago; near Romeoville and Plainfield in Will County; near Lisbon in rural Kendall County; three tornadoes were near Grant Park in Kankakee County. In Indiana, one tornado was confirmed in Lowell and another near DeMotte.

Severe straight-line winds were recorded near Morris in Grundy County.

The Storm Prediction Center said these storms met the criteria as derechos, or powerful storm clusters that produce intense wind damage for 250 miles or more.

Two separate derechos affected the Chicago area Monday night.
