Scattered severe thunderstorms capable of damaging wind gusts and some hail are expected this afternoon and evening from the Upper Ohio River Valley into the Northeast, and from the Appalachians into the Mid-Atlantic States. Excessive rainfall from heavy thunderstorms may produce areas of flash flooding from southern New Mexico into the western and northern Gulf Coast into Wednesday. Read More >

Widespread heavy rain fell from the end of August through early September, and also in October across the region. Rainfall totals over 20 inches fell in just 3 months across much of eastern IA and northwest IL. This water fell across already saturated soils, and eventually found its way into area rivers and tributaries. This led to significant rises of river levels, and eventually moderate to major flooding. The Wapsipinicon, Rock, English, Skunk, Iowa, Cedar, Pecatonica and Mississippi Rivers were all affected. |
