Low pressure deepened as it moved from eastern Colorado on April 4 to central Minnesota on April 5. Slightly warmer and drier air aloft east of the upper-level low track kept any more persistent measurable precipitation mainly from the James River valley westward, but also limited the type to mainly light freezing rain and freezing drizzle except for more elevated areas west of the James River.  Several locations had ice accumulation from one-tenth to one-quarter inch, with a narrow zone from 2 to 5 inches of snow from Chamberlain to Wessington.  Northerly winds gusted to 30 to 45 mph as precipitation was coming to an end, but the overall lack of snowfall kept visibility from being significantly reduced.
