At least one person was killed when severe storms swept through Oklahoma early Thursday evening, destroying property and covering the area with golf ball-sized hail.

One of the most severe storms hit Pawnee, Oklahoma, about 70 miles northeast of Oklahoma City, with winds strong enough to overturn several RVs at the Pawnee Lake campground. According to the Associated Press, Pawnee County Sheriff Darrin Varnell confirmed that one person who was in an RV during the storm had died.

The National Weather Service is conducting a damage assessment to determine whether the damage was caused by straight-line winds or a tornado.

Further north, severe thunderstorms moved across Minnesota and Wisconsin. Hailstones ranging in size from quarters to ping-pong balls were common in the storms, but one storm managed to spawn a tornado north of Duluth, Minnesota.

Thursday’s storms are a reminder that severe weather can be destructive and deadly even outside of the traditional spring storm season.

People in the central United States should keep an eye on the skies and monitor the forecast on the AccuWeather app as more severe thunderstorms are expected for the weekend.
