Pierre, SD – The National Weather Service has issued Severe Thunderstorm Watch 588 for much of South Dakota, warning residents of potentially damaging storms expected to develop Wednesday afternoon and evening. The watch remains in effect until 10 p.m. MDT.
According to the NWS Storm Prediction Center in Norman, Oklahoma, the affected counties include Bennett, Brule, Butte, Charles Mix, Custer, Fall River, Gregory, Haakon, Hughes, Jackson, Jones, Lawrence, Lyman, Meade, Mellette, Oglala Lakota, Pennington, Stanley, Todd, Tripp and Ziebach. Forecasters say storms could bring wind gusts over 60 mph, large hail, and frequent lightning.
Meteorologists warn that isolated tornadoes are also possible, though the primary threats remain strong winds and hail. The unstable air mass over the region, combined with a passing cold front, is expected to fuel the severe weather risk through the evening hours.
Residents are advised to monitor local forecasts, have multiple ways to receive weather alerts, and be prepared to take shelter if warnings are issued. Outdoor plans, especially in rural areas, should be reconsidered until the storms pass.
Drivers are urged to use caution, as heavy rain could reduce visibility and cause water to pool on roadways. Those traveling in open areas should remain alert for rapidly changing weather conditions.
Forecasters say the threat should diminish late tonight as storms weaken and move east, but scattered showers may linger into the overnight hours.
