With an area of low pressure slowly spinning away to the east we’ve had some continuing rain and thunderstorms, mostly in northwest Iowa and southwest Minnesota. After yesterday’s deluge, Sioux Falls has had another 18/100” since midnight. Skies have been mostly sunny in northern and western KELOLAND. There is also a bit of smoke in the west. Thanks to a fairly brisk northerly wind, temperatures have only been in the 60s and 70s, well below normal.
Tonight will be a fairly cool night, in the low 50s, with a light northerly breeze under clear to partly cloudy skies. There will be a chance of showers or possibly a weak thundershower West River.
Tomorrow skies will be partly to mostly sunny, and thanks to a gentle northerly breeze it will again be much cooler than normal. Highs will only be in the low to mid 70s. There is a slight chance of showers in western South Dakota.
High pressure will clear the skies on Wednesday, and we’ll be a tad bit warmer. A light southwest breeze will work with the sunshine to push us to the upper 70s to low 80s.
Thursday will be partly cloudy, in the upper 70s to low 80s East River, and the mid 80s West River. But Thursday evening through Friday morning we’ll have a decent round of thunderstorms, and early indications are they could be pretty strong.
Behind the thunderstorms, the weekend is looking warm – and humid in the southeast. With mostly clear skies from Friday afternoon through Sunday afternoon, highs will be in the 80s those three days. Monday is also looking quite warm
Right now it looks like highs will be in the low 80s the rest of next week through the Labor Day weekend.
