Look for a slight chance of rain in the west tonight with mild lows in the upper 50s to lower 60s. Tomorrow will be even warmer and windier with highs in the upper 80s to lower 90s.
The weekend will start warm ahead of a cold front. The wind will once again blow in from the south…likely 15-30mph in the afternoon. Rapid City will have the best chance of t-storms, with a line of severe weather possible in the afternoon advancing toward Pierre late in the day. Those storms should lose their punch as they move east overnight, but we’ll monitor that trend the next couple of days. We are forecasting scattered rain for Sioux Falls and Aberdeen late Saturday night through the first half of Sunday. Breezy northwest winds and cooler weather will arrive on Sunday, but the winds should relax by Memorial Day with highs staying in the 70s early next week.
Another warm day is forecast in KELOLAND with highs in the lower to middle 80s, but the wind will be increasing through the day in central and western KELOLAND. We are forecasting winds southeast at 20-40mph again for Pierre and Rapid City. Sioux Falls and Aberdeen will be mostly in the 15-25 mph range.
