As sure as the changes in the seasons go every year, we're starting to see a pattern change in the weather during our last month of meteorological summer.
The heat ridge that was responsible for the hot and dry weather in June and July is showing signs of weakness. The hot and dry dome of air is not covering as large of an area as it was last month.
This will allow for cooler weather and better chances for rain in KELOLAND and the upper plains.
Our first hit of cool air arrives this weekend after another round of rain on Friday and Saturday. That's when much of eastern KELOLAND will have highs in the 70s to near 80 degrees. Sioux Falls hasn't had a day in the 70s since June 21, the first full day of summer.
Temperatures will slowly warm on Sunday and into next week as the ridge tries to redevelop, but another hit of cooler weather will move in from the north late in the week and into next weekend. This will bring another chance for rain ahead of it and widespread 70s to KELOLAND by next weekend.
It's a sure sign that summer's heat is trying to leave us as we get closer to autumn.
