The heat won't be extreme, but the combination of warmth and humidity could make a busy day walking around the fairgrounds feel a little steamy.

Scattered showers and thunderstorms are expected to develop Sunday afternoon and evening across western Minnesota, where instability will be greatest.

A few of those storms could become strong, with gusty winds and hail possible. However, the storm activity should have a difficult time maintaining strength as it moves east.
