"It’s the third 1-in-1,000-year rain event in the Lower 48 states in about a week".

"If it seems like a barrage of extreme rain events has been wreaking havoc across the country over the past week, you’re not imagining things. The latest resulted from an overnight deluge in central and southeastern Illinois, with some areas registering 8 to 12 inches of rain in less than 12 hours.

It’s the third 1-in-1,000-year rain event in the Lower 48 states in about a week.

The National Weather Service office in Lincoln, Ill., has received about 20 reports of flooding, mostly due to water inundating roads and intersections. Television affiliate WAND in Decatur, which is about 35 miles east of Springfield, reported cars submerged in high water with emergency crews involved in rescues. Minor flooding of several rivers has also occurred.

Flash-flood warnings have affected a large swath of central and southern Illinois from around Springfield to southeast of Effingham. That’s where months’ worth of rain has fallen because of a parade of thunderstorms. Many of them were “training” or repeatedly moving over the same neighborhoods."
