Today should be the mildest of the coming seven. A massive ridge builds over the southern Great Plains, opening up the Gulf of Mexico and allowing the mercury to spike. We’ll still be above average for highs today, just not as much as next week.
Clouds are also coming in from the southwest as a weak boundary brings a slim shot of thunderstorms later today. Wind and humidity will both increase as two weather systems come closer. Highs will be between the mid 80s and low 90s.
Isolated storms should begin moving into the Hills and far southwest first. Then we expect a few around Interstate 90 east of Sioux Falls. The coverage will be very hit-miss and it’s definitely not a lost day.
These continue to quickly move northeast later this evening. We’ll have a few leftover morning showers tomorrow but clearing skies should quickly take over. Then it’s just going to be plain hot and humid. We’ve got a chance of going 100°+ in central SD tomorrow afternoon.
Most of the shower chances in the extended forecast stay well to the north or east of KELOLAND. This pattern moving in has no signs of weakening and that means above-average temperatures.
Limited rain chances return at the end of the week, likely Thursday into Friday.
