A strong upper level trough will track through the Dakotas, dragging much cooler air south, with bands of thunderstorms tracking along a cold front that will push eastward. Sunshine and warm temperatures will carry through the morning before the clouds increase in the afternoon with potential for thunderstorms increasing after 1 pm. A few of those storms have to the potential to turn strong to severe during the late afternoon, early evening hours.
In the wake of that front, more autumn-like temperatures will be felt statewide, just in time for the official start of the autumn season Saturday evening.
