…Patchy Freezing Drizzle and Areas Of Light Snow Creating Slick Conditions, Additionally Accumulating Snow and Blowing Snow Friday into Friday night… .A weather system passing across the state this morning is producing a variety of weather across Iowa. Over the north, light snow is falling. Across southern Iowa, the weather is a bit more messy. Patchy freezing drizzle is occurring along with areas of fog. Both are putting down a light glaze of ice on sidewalks, elevated surfaces and untreated roads. In addition, light snow is occurring in some areas also making some roads slick. The morning commute will be difficult especially on secondary roads and elevated surfaces. A second stronger system will impact the state Friday into Friday night bringing accumulating snow to the entire state of Iowa. Snow will spread across the state Friday morning into Friday afternoon and continue through the evening hours into early Saturday morning. Widespread moderate to locally heavy snow is expected. North to northeast winds will increase Friday afternoon through Friday night creating areas of blowing and drifting snow as well. There is the potential that some or much of the advisory area for Friday into Friday night may be upgraded to a warning at some point. Snowfall rates may be higher at times during the Friday afternoon commute which could lead to slick, snow-covered roads and reduced visibilities.
