 Meteorologist Brian Pierce is pinpointing the time a touchdown may take time due to the scope of the storms. We did have straight-line winds of 70 to 75 miles an hour coming through the Quad Cities area. Up around the Dubuque area, wind speeds were pushing 100 miles an hour. National Weather Service office in Des Moines confirmed at least one tornado touchdown Monday night in Urbandale. It went through Windsor Heights and into Des Moines before it lifted back up.
