Storm risks begin to grow after 5pm, especially in areas along and north of Highway 14 and into central and western South Dakota. A few strong to severe storms could bring risks of 1.5 inch hail, 70 mph winds, and even a tornado along or north of Highway 14. Storm clusters will move east after dark, with a gradually diminishing severe weather risk into Wednesday morning.
A storm or two could redevelop in the area on Wednesday afternoon. While severe weather risks are on the lower side, an isolated storm could produce quarter size hail and 60 mph winds. Storms will move away from the area Wednesday evening.
Hot and humid conditions on Tuesday bring risks for storms into Wednesday morning. Those storms may linger in the area Wednesday, with dry weather anticipated for the rest of the week and through the upcoming weekend. One thing you'll notice is warming temperatures by next weekend, with highs surging back into the middle 90s to even near 100 degrees in central South Dakota and Nebraska.
