Sioux Falls, South Dakota – Scattered severe thunderstorms are set to target eastern South Dakota between 7 p.m. Tuesday and 4 a.m. Wednesday, threatening ping pong ball-sized hail, 65 mph wind gusts, and pockets of heavy rainfall across the region.
According to the National Weather Service in Sioux Falls, storms will develop this evening, primarily impacting the I-29 corridor, Sioux Falls, Watertown, Brookings, and extending south to Yankton. The main risks include damaging winds, large hail, and locally heavy rain, with a Level 2 risk (scattered severe storms) highlighted across much of the state. Travel on I-90 and I-29 could be hazardous, especially during the overnight hours, as strong winds and reduced visibility may occur with these storms.
Residents in Minnehaha, Lincoln, Brookings, and surrounding counties should closely monitor weather alerts and consider moving vehicles to shelter to avoid hail damage. Charge phones and prepare for possible power outages, especially in rural areas prone to downed lines. If you’re traveling, avoid low-lying roads due to the risk of flash flooding, and be prepared to seek shelter quickly if warnings are issued.
Storms are expected to weaken after 4 a.m., but additional updates or warnings may be issued overnight. Stay tuned to local alerts for the latest information.
