Moderate to heavy snows are expected to spread north to south into Iowa Monday morning and continue well through the evening hours. The National Weather Service says this will result in widespread moderate to heavy snow accumulations across central and southern Iowa. Accumulations of a foot or more are possible south. There will also be a sharp gradient in snowfall accumulations somewhere near the Highway 30 corridor.

Snow amounts may vary greatly over short distances north to south. Snowfall rates may often be an inch per hour in areas of heavier snowfall. These intense snow rates and northeast winds gusting from 30 to 35 mph will produce near blizzard and whiteout conditions. Travel will be difficult to impossible at times. The snowfall should end Tuesday morning with wind beginning to diminish as well.
