It is going to be sunny, warm and somewhat humid for the next couple of days. Highs will reach the mid 80s in Sioux Falls today while parts of central South Dakota warm into the low to mid 90s. Tomorrow will be warmer and a little breezier with high temps ranging from the low 90s in Sioux Falls to the mid 90s across central South Dakota. It’s not going to be quite as humid as it was the last time we had a string of 90 degree days, but you will definitely notice the humidity.
A powerful cold front will blast across the Dakotas Thursday and Friday, moving into Iowa and Minnesota late Friday into Saturday. That front will bring a good chance of thunderstorms, and some of them will probably be severe. Severe storms are possible across central and northern South Dakota Thursday afternoon and Thursday night, the severe weather threat will shift to southeastern South Dakota, southern Minnesota, eastern Nebraska and western Iowa on Friday. Storms should end by late Friday night in most places, however, they could linger into Saturday morning across the extreme southeastern part of our KSFY coverage area.
After the front passes, cool and dry Canadian air will slip in from the north. Saturday and Sunday will be mostly sunny with highs only reaching the low 70s Saturday, we will warm back to the mid to upper 70s by Sunday.
