Storms are expected to start in southeast South Dakota and last throughout the evening and be calming down shortly after midnight tonight. Some of the storms this evening are expected to be severe. High winds, hail, and isolated tornadoes are expected from these storms. The greatest tornado threat in KELOLAND is in northwest Iowa.
Along with those storms, a secondary round of storms looks to move into South Dakota from Wyoming in the early afternoon. These are expected to move across the area but weaken once they run into the stable air behind the storms already in the east.
Lows tonight cooling down to the 50s across much of the area with clearing skies once the front moves on.
Another small chance for rain tomorrow as the leftovers of this system passes over. Current timing of the rain has it in western and central South Dakota during the day and in the eastern side of the state during the evening hours.
The next work week will start off cooler with highs in the mid to upper 70s and slowly warming up to the 80s by Wednesday. The 2nd half of the week will cool down again with highs back in the 70s.
