Warm today, then much cooler this weekend.

RAPID CITY, S.D. (KOTA) - Isolated showers and thunderstorms are likely this morning as a weak disturbance moves east through the area. Today will be another warm day, but a cold front will bring much cooler temperatures this weekend.

Isolated showers are possible late tonight into early Saturday morning. Saturday will be mostly dry with sunshine and 70s.

Sunday, clouds and showers will keep temperatures way down - in the 60s, with only 50s in the higher Black Hills!
