There is a slight risk of Severe Weather for Sunday. This is for areas north of a line from Waukon to Iowa Falls to Sioux City. This would include the cities of Fort Dodge, Mason City, Spencer and the Iowa Lakes Region. The main threats will be large hail and damaging winds. An isolated tornado is not out of the question but the greatest threat of tornadoes will be in southern Minnesota. Current activity in eastern Iowa (at 3am) may figure into new development later today and tonight.
