NEW: Flash Flood warnings are issued for parts of the Stateline until around 5AM Tuesday. Some private weather stations have recorded rainfall rates up to 2-3 inches per hour with some of these storms. While storms are moving out of the area, any potential flooding may take a bit longer to recede. This is why the warnings are in place so long into the night.

As of 12:30AM, here are the following warnings in place:

  • Flash Flood Warning for Winnebago and Boone Counties until 5:00AM. Radar estimates that 1-3 inches of rain has fallen in these areas.
  • Flash Flood Warning for McHenry County until 5:15AM. Radar estimates rain rates of 1-2 inches per hour with isolated areas reaching 3 inches per hour.
