May Precipitation Highlights:
​May 30: The remnants of Tropical Storm Alberto tracked northward along the Illinois/Indiana border. Widespread moderate rain fell east of I-57 through mid-afternoon, with total rainfall amounts of 1.50 - 2.00". Further northwest, a persistent band of moderate to heavy rain developed overnight into the early morning near the Illinois River. This band dropped impressive rainfall amounts of 2 to 4 inches, with localized amounts as much as 5 inches from just northwest of Springfield northward to near Peoria and Henry. This caused flash flooding in portions of Tazewell, Woodford, and Marshall counties.
