The highest rainfall amount recorded by 2 p.m. Thursday afternoon was 2.33 inches in Shandon, Ohio. The highest rainfall totals in each county can be seen in the graphic below.
The steady rain is the result of the remnants of Tropical Cyclone Zeta and a deep low-pressure trough working together to send moisture into the Miami Valley.
Rainfall totals were in a deficit for the month until we saw an event that brought 1.92 inches of rain to Dayton Oct 18-21.
