Slight Risk of Severe Storms Today

Heavy Rain Possible Today

Thunderstorms will develop early this afternoon into central SD, then progress southeast through this evening. Locally heavy rain, possibly as high as 4-5 inches, will be the main threat. Hail to the size of quarters and wind gusts to 65 mph will also be possible.

Rain will be a welcome site for many today but too much in a short period of time can still cause some concerns. While widespread impacts are not expected, isolated flash flooding is possible with urban and flood prone areas most likely to encounter issues. Thunderstorms this afternoon and evening will be efficient rain producers with rain rates perhaps exceeding 2 inches per hour. If storms persist over a location for a longer period, localized rain totals exceeding 4 inches are possible.
