It is going to be another warm and humid day. Afternoon temperatures will range from the upper 80s to low 90s, but the heat index will soar back into the mid to upper 90s for many.

Another system will bring a chance of thunderstorms late today and this evening across central and western South Dakota. Thunderstorms will move east overnight tonight into tomorrow morning and then redevelop across parts of eastern South Dakota, Minnesota and Iowa tomorrow afternoon and evening. Once again, some storms could be severe with the potential for heavy rainfall amounts of one-quarter to one-half inch or more.

The weekend ahead will be sunny, cooler and not as humid. Highs will still reach the upper 80s to low 90s on Saturday, but afternoon temps will drop into the low 80s by Sunday. The cooler 80s will stick around into next week with a chance of showers and thunderstorms by late Tuesday night into Wednesday.
