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 Slight Risk (level 2 of 5) for severe weather is in effect over central, north central and northeast South Dakota, mainly for this evening through the overnight. There is still some uncertainty surrounding where and when storm initiation occurs, and how much coverage there will be. Large to very large hail (1 to 2+ inches) and damaging wind gusts up to 65 mph are currently the main threats.
Isolated to scattered storms could develop by early this evening over western South Dakota before making their way east-southeast across the region overnight. Initially, large to very large hail poses the main threat. But, eventually storms could organize overnight into one or more line segments with the potential for damaging winds increasing.
