Rapid City, SD – A dynamic weather pattern is unfolding across South Dakota, with severe thunderstorms expected to sweep through central parts of the state today, followed by an intense heatwave. Residents should prepare for a range of hazardous weather conditions, starting with a cool front bringing relief from recent heat but also sparking potentially severe storms.
The National Weather Service in Rapid City has issued a severe thunderstorm warning for Wednesday, with wind gusts potentially exceeding 60 mph and the possibility of hail over 1 inch in diameter. These storms are expected to be isolated to scattered, primarily affecting central South Dakota, with cloud-to-ground lightning posing an additional risk. The storms are anticipated to develop in the late morning and persist through the evening hours.
As the week progresses, a significant shift towards hotter and drier conditions is expected. By Thursday, temperatures are predicted to climb into the upper 90s, with some areas reaching as high as 103°F on Friday and Saturday. The heat, coupled with low humidity levels, will elevate fire weather concerns across the region.
The extended forecast indicates a slight cooldown beginning Sunday, with highs in the mid-90s, but the threat of dry conditions and fire danger will likely persist. Residents are urged to monitor local weather updates closely and take precautions, particularly during the peak of the heatwave later this week.
