An overturned semi blocked the westbound lane of traffic on the north side of I-80 Wednesday afternoon. During the severe thunderstorm in the area high winds blew the tractor trailer over near exit 80 in Adair County. Adair and Casey Fire and Rescue as well as DOT officials secured the scene and were able to remove the obstacle which slowed traffic for a time. Damage to cities in Guthrie Center, Stuart and Panora was limited to tree branch knock downs.
