For anybody into pointless stats -- ORD is going to do something this month that hasn't been done in a while, and that is to finish a month at an exact number of inches of precip. In this case, June 2026 will end right at 5.00"
The last time there was a month with x.00" of precip was March 2013, which had 2.00". Basic math says that this kind of thing has a 1/100 chance of happening, but it has been 159 months since it happened.
