One long-range computer model can take us out to the official end of summer, which is September 21 this year. And it's interesting to note that it keeps steady rain chances coming for the next six weeks.
Raw computer data suggests that widespread rain amounts from now until September 21 range from three and a half to as much as seven inches. The seven inches are coming in from one of the driest areas over the past 30 days, northwest Iowa.
When compared to average, it ranges anywhere from as little as three-quarters of an inch above average in Pierre to as much as two and a third inches over in Sioux Falls. The heaviest rains are expected in eastern KELOLAND.
Along with the rain chances, temperatures are expected to remain cooler than average. By the official first day of fall the average highs are in the upper 60s to lower 70s. So with the cooler than average forecast over the next six weeks, don't be surprised to have more afternoons with highs in the 60s.
