Ejection of the main upper level wave (which had already steered a pair of snow producing systems across the area during the prior week) brought yet another light to moderate snowfall over northwest Iowa, southeast South Dakota, northeast Nebraska and southwest Minnesota.  While it generally snowed for five to eight hours at most across northwest Iowa, a majority of that time found visibility of a mile or less. Snowfall amounts 2 to 5 inches were common, with around an inch or less from the lower Missouri River valley eastward toward Storm Lake.  Roads rapidly became snow-covered and hazardous due to the snowfall rate.
