Flash Flood in Clark County, Illinois

Periods of showers and thunderstorms which produced up to 4.00 inches of rain from June 25th into the morning of June 26th saturated the ground and swelled area creeks in northern Clark County. A round of thunderstorms during the afternoon of June 26th rapidly produced an additional 3.00 to 5.00 inches of rain resulting in widespread flash flooding. Most roads were flooded in the northern part of the county, and one road washed out about 5 miles north of Marshall. U.S. Highway 40 and State Route 1 were closed at times. Several homes and businesses in the city of Marshall suffered flood damage. The widespread flooding did not subside until late in the morning on June 27th.

A weak upper-level disturbance triggered scattered thunderstorms across central Illinois on June 26th. Many of the storms produced locally heavy rainfall and areas of flash flooding, while one cell dropped nickel-sized hail in Bridgeport in Lawrence County. The flooding in northern Clark County persisted until the morning hours of June 27th.
