Torrential rainfall amounts from 6 to 12 inches occurred over a two-day period, causing an historic flood event. A very slow-moving cold front over southwest Illinois and southeast Missouri provided the focus for prolonged heavy rainfall. A deep southwest wind flow brought subtropical moisture across the frontal zone. Two-day rainfall amounts included 11.64 inches at Anna (Union County) and 11.50 inches at Galatia (Saline County). At the Carbondale airport, the two-day total was 6.61 inches. Other two-day totals included: 7.66 at Harrisburg, 7.53 at Mt. Carmel, and 10.50 at Du Quoin.
