September did not bring relief for Nebraskans in the north-central part of the state, where some communities saw 4 to 8 inches of rain over a two-day period. Ainsworth recorded 8.01 inches over two days and ended the month with nearly 10 inches of rainfall, a good 7 inches above average.

Across the state, the average overnight temperatures were higher than normal, helping the average minimum temperature to come in as the warmest on record. These wet and warm conditions did help some crops mature, but they also allowed fungal plant diseases to strike corn across the state.
