Starting tomorrow, the first chances of strong to severe weather shows up across western South Dakota. By Friday afternoon into the evening hours and overnight, an isolated strong to severe storm with gusty winds and hail are possible.
On Saturday, statewide chances of severe storms are expected, with the best chance over the eastern half of the state. The thinking on Saturday is that isolated thunderstorm development is possible across western South Dakota during the afternoon hours.
By the evening and overnight hours, thunderstorm development for eastern South Dakota will depend on temperatures as much warmer air will move into the area. If storms do develop, they are expected to become severe.
Sunday looks to bring the best risk for severe thunderstorms as the focus will be across the east. Warmer temperatures will surge into this area and increase the dewpoint and humidity levels. A front will move into the region, which will be the focal point for thunderstorm development. Thunderstorms may start to develop in the afternoon, but are more likely during the evening and overnight hours.
Then by Monday, another round of strong to severe storms is possible, mainly along and east of Interstate 29 and into Minnesota and Iowa.
