Another Severe Thunderstorm Warning was issued around 12:30 Thursday afternoon, this time for southeastern Osceola County, northeastern O’Brien County, Clay County, and Southern Dickinson County. These storms were forecast to drop hail up to ping pong ball size.

A line of severe thunderstorms rumbled through the KIWA listening area Thursday morning.

The storm generated Severe Thunderstorm Warnings in east central and southeast South Dakota beginning at about 4:35 this morning, with the large system moving to the east-northeast at about 45-miles-per-hour. The first warnings were issued for northwest Iowa around 8:20 this morning, and continued through about 9:30 am.

The Severe Thunderstorm Warnings, which were issued by the National Weather Service office in Sioux Falls, said radar had indicated the severe thunderstorms, with a forecast of heavy rains, winds gusting up to 70-miles-per-hour, and hail as large as a half-dollar.

As of noon Thursday, no major damage had been reported to the National Weather Service, or the area law enforcement agencies.

In Rock Rapids, they experienced some small hail, along with strong winds, and 1.7-inches of rain during the early morning storms. Lyon County Sheriff Stewart Vander Stoep says in his hometown of Doon there was a lot of water, and some tree limbs down, but no major damage. The NWS in Sioux Falls indicated that it had appeared that the Doon and Alvord area had received the worst of the storm.

In George, our trusty weatherman Clarence Stubbe reported some small hail, high winds, and heavy rain, with 1.6-inches of rain falling during the time the storm passed over George.

In Sibley, the Osceola County Sheriff’s Office says they received no hail during the severe thunderstorm warning period, just strong winds and rain.

In Rock Valley the heavy rains caused some city streets to be closed for a time Thursday morning, due to flooding.

In Orange City, the Police Department had received no damage reports from that city, they had avoided the hail, but had some strong winds and heavy rain.

At noon on Thursday, the trailing edge of a thunderstorm passed over the Sheldon area, bringing with it 0.22-inches of heavy rain and pea-sized hail.
