Precipitation in Illinois for April was more complicated.
April precipitation ranged from 2 to 4 inches in northern and
central Illinois to 4 to 7 inches in southern Illinois. As a
result, the northern two-thirds of the state was slightly below
average, while the southern third was up to 2 inches above
average. Fort Massac State Park reported the highest monthly
precipitation total of 7.80 inches.
The Midwest had alternating bands of dryness and wetness for
April. The above-average precipitation in southern Illinois
extended into Indiana, Ohio, Kentucky, and the rest of the Ohio
River Valley. Just to the north was a band of slightly
below-average precipitation across Missouri, northern Illinois,
northern Indiana, and parts of Michigan. Another band of wetter
conditions extends from Kansas, Iowa, Wisconsin, and western
Michigan. Drier than average conditions have prevailed for
several months in Minnesota and the Dakotas.
