Results of March Weekend Snowfall Across the Area

A quick moving disturbance brought accumulating late winter snowfall to the area overnight and early Sunday.  Two elements worked together to produce a fairly narrow band of snowfall. First, very dry air poised north of the system kept the snowfall from pushing too far northward. Second, a warmer plume of air off the surface pushed northward through northwest Iowa, northeast Nebraska, and extreme southeast South Dakota.  This allowed a changeover to light freezing rain.  Below is a map and listing of the accumulated snowfall totals from the system.

A satellite picture at midday reveals the some of the swath of snow left behind by the winter system.  One thing to note is the narrow tongue of snowfall which extends up through the western side of the Sioux Falls area.  This corresponded to a brief enhancement to snowfall which resulted in one inch snowfall in about a 45 minute period on Sunday morning.

In just a mere two hours, note just how much of the snowfall had melted with the strengthening March sun, and what additional heavier snowfall was revealed by the exiting and dissipating clouds.  Since the Missouri River was still frozen upstream of Fort Randall Dam, the snow remained on the river while melting along the surrounding banks.
