Sunny skies lit the way for Springville farmer Wayne Hicks Monday as he took his tractor on the frontage road along I-15 to a shop for repairs. Skies were foggy Tuesday morning in Utah County, and the National Weather Service predicts they will remain that way morning and evening through Wednesday, with fog thinning in the afternoon. Tuesday was upgraded from a "yellow" to a "red" day for Utah County due to pollution.
