Severe Weather and Heavy Rainfall from the Midwest to the Ohio Valley; Mid-Summer Heat Continues

Severe thunderstorm and heavy rainfall threats will persist from the Midwest to Lower Great Lakes through Monday, shifting into the Ohio Valley and Central Appalachians Monday evening into Tuesday. Mid-summer heat will continue across much of the CONUS this week, with record highs possible well into the 100s across the south-central High Plains. Read More >

A system of showers and thunderstorms will move across the area late tonight into tomorrow morning. Instances of ponding or flooding may occur, especially in areas that saw flooding the past couple of days. Conditions finally look to quiet down for the early part of next week.
Scattered showers and thunderstorms capable of producing torrential rainfall will continue to spread across the area overnight tonight. Given the already saturated soils, this could lead to additional instances of flooding. The most vulnerable areas for flooding tonight will be near and south of I-80 and across northwest Indiana, where a Flood Watch is in effect until 10 AM CDT on Sunday. Localized flooding will be possible north of the watch area.
