Monday's Forecast

After a scorcher of a rally week, a cold front has slipped through the area. This cold front will bring cooler conditions and chances of showers and thunderstorms that are exactly what the firefighters were hoping for. It'll also help sweep the Vineyard Fire's smoke away from the Black Hills, though smoke from Canada will remain an issue.

Behind the cold front, temps will fall below typical August numbers. Most areas will settle for highs in the 70s or low 80s. Another wave pushes through the area in the afternoon and evening, kicking up another round of thunderstorms. Some could be strong, especially west and south of Rapid City. Storms won't be widespread, but any lone wolves that pop up could produce hail and damaging winds.

Extended Forecast

Another round of storms is possible on Wednesday afternoon and evening. Most of the strongest storms will be in Nebraska.

Drier conditions are anticipated for Thursday and Friday and the extra sunshine will help push temps briefly higher. The busy pattern returns for the weekend, knocking temps to their knees and opening the door for more chances of increasingly needed showers and storms.
