Heavy thunderstorms rumbled across parts of northern and central Iowa overnight, bringing winds up to 65-miles an hour — ripping up shingles, knocking down tree limbs and knocking out power to thousands. Myrna Wolfswinkel, of Sheldon, was vacationing with her family in Otter Tail, Minnesota, when the storms hit last night. Wolfswinkel says “I was in the cabin with my grandson and it kept getting worse. We crawled under the table. I could see the clock. It wouldn’t stop blowing. It was blowing for at least 20 minutes. It was really scary.” She says there was a lot of moderate damage in the campgrounds.She says “Lots of trees down. A couple trees on the roof of my daughter’s cabin — there was a big tree on her cabin. On our cabin, there was a big branch. We heard it fall and got scared. But no injuries; we were thankful for that.” A truck was blown over in Nevada, Iowa, last night — the driver had to be cut out.
