Severe thunderstorms capable of very large hail, damaging wind gusts, and a few tornadoes are possible today across parts of the central and southern Plains. Heavy rain will pose a threat for flash flooding across portions of central and coastal Texas. Thunderstorms may also cause isolated wind damage across the Southeast. Read More >
Overview
|
Thunderstorms developed during the late morning and early afternoon across a zone just south of I-80 in northern Illinois and northwest Indiana and persisted for several hours. An extremely moist environment set the stage for very heavy rainfall rates. In addition, storms were moving slow and training over the same areas. This brought about flash flooding due to rainfall amounts estimated at three plus inches, and possibly near six, in some locations. The hardest hit communities were Braceville and Odell in northern Illinois, and in Indiana near the town of Hebron experienced very heavy rainfall. |
