It’s going to be hot and humid across the region today, especially in parts of southeastern South Dakota and northwest Iowa. High temperatures will warm into the upper 80s and low 90s for most of us. Dewpoints in the 70s throughout the day will allow heat index vales to climb into the mid to upper 90s and even triple digits at some points this afternoon. Expect mostly sunny skies with a few scattered afternoon rain showers and thunderstorms in parts of southwest Minnesota and northwest Iowa.
More rain will develop West River overnight and will eventually move into the Missouri River Valley by early tomorrow morning. The rest of us will have the chance for scattered afternoon thunderstorms. Temperatures will continue to cool down day by day and by next week we’ll be well below average in the 70s!
