Here are 24 hour rainfall reports and a summary of how precip’s been running across Chicago and The Midwest the past 30 days

The “hit or miss” nature of warm season rainfall was on display again Wednesday.

My WGN meteorological colleague Mark Carroll has broken out some of the heavier 24 hour rain totals across the Greater Chicago area and in areas surrounding.

Not everyone saw the rain. The map of rainfall reports and the plot of Doppler radar estimated rainfall among the graphics below offers a look at who saw rain and who didn’t.
