Sioux Falls, SD
We have areas of dense fog this morning in KELOLAND, with a dense fog advisory posted for both Aberdeen and Watertown. The fog should dissipate during the morning with highs returning to the upper 70s in the southeast, with upper 80s to near 90 in western KELOLAND. The grassland fire danger index will be very high to extreme in the west.
More fog is possible tonight with mild lows in the upper 50s to lower 60s. The fog should lift and afternoon temperatures will be very warm in the 80s most areas. The warm weather will continue into the weekend with widespread upper 70s to lower 80s.
Changes are on the horizon early next week. Scattered showers and thunderstorms are possible by Monday or Tuesday. The weather still looks at or above normal through Wednesday, but colder air and better chances of showers and thunderstorms could arrive by the middle of next week.
We don’t have the details yet, but colder air is likely late next week. In fact, it could be cold enough for some snow again in the Black Hills. Stay tuned.
