Sioux Falls, SD
A very hot day is in the forecast with a heat advisory in effect for much of central and eastern KELOLAND. Heat index values are expected to range from 100 to 105. The hottest temperatures should be found in central South Dakota, with highs in the 100s for Pierre south into northern Nebraska.
The heat and humidity will fuel big storms later today in North Dakota. We are keeping a close eye on storm potential in northern KELOLAND by early this evening, including Aberdeen. The cap will be strong in much of the region, but the area closest to the North Dakota will be more subject to storm development. Any storms that bubble up will likely produce very strong winds over 70 mph and large hail. Stay alert to the latest forecasts if you live in the northern and northeastern portions of KELOLAND. Sioux Falls and many other areas will likely stay dry tonight.
Tomorrow looks a little cooler with highs in the lower 80s in Aberdeen and mid to upper 80s in Sioux Falls. There will be a chance of afternoon t-storms in the Black Hills.
The next chance of thunderstorms will arrive on Thursday into Friday in KELOLAND. This will be the best chance of rain for the week for the Sioux Falls area. Temperatures will remain near normal at the end of the week with lower to middle 80s East River and warmer numbers in the west.
