Sioux Falls, SD
We have another hot day in the forecast in much of eastern KELOLAND, but relief is in sight. A cold is moving into northwestern SD and strong northwest winds will accompany this system. As a result, it will be significantly cooler across the west with highs of 85-90 very likely in Pierre and Rapid City. Aberdeen will be warmer near 90, but the front will arrive around midday and the switch in wind direction will drop the humidity. Sioux Falls still has an excessive heat warning today, but the dewpoint will be lower than previous days with highs in the mid 90s. The front will go through KELOLAND mainly dry, with only chance of rain affecting far northeastern KELOLAND early this afternoon.
Tomorrow will be cooler with highs in the mid 80s to near 90. By Thursday night and Friday, isolated clusters of t-storms will be possible as more humid air tires to make a return as we start the weekend. We’ll carry a 20% chance of rain in many areas Friday and Saturday. Otherwise, warm weather will continue into next week highs mainly in the upper 80s to near 90.
