A late season snow storm developed over the southern Rockies during the night of the 5th into the morning of the 6th.  The upper system was quite separated from the surface features.  Though the surface low tracked across southern Kansas and eventually through Missouri, the upper level low pressure moved northeast into northeast Nebraska by the morning of the 7th, before sinking slowly southeast across Iowa.  A cold air mass was in place to the north of Iowa.  A mixture of precipitation occurred across the state.  Over the far south, all of the precipitation fell in the form of rain.  Precipitation was mixed over the central counties, and predominantly snow over the north.  Though there was a mixture of freezing rain and ice pellets in the central counties, the amounts were not all that significant.  Significant snowfall occurred north of Interstate 80.  Due to the prolonged nature of the event, many areas did not meet the criteria of a winter storm.  Snowfall along the I-80 and U.S. Highway 30 corridors was generally in the 3 to 6 inch range.  The snow fell over a 24 hour period.  Heavy snowfall occurred from about U.S. Highway 20 and north.  During a 12 to 18 hour period, snowfall of 7 to 10 inches was common.  Some of the heavier snowfall amounts were 10.1 inches in Worth County at Northwood, 9.4 inches in Kossuth County at Swea City, and 9 inches in Webster County at Fort Dodge.  Travel was hampered to some extent during the nighttime hours, but with ground temperatures in the low 40s F., conditions improved quickly after sunrise.  Blowing and drifting snow was limited because of the heavy, wet nature of the snow.  Winds during the height of the storm were from the east at 20 to 45 MPH.  This caused significant drifting in open areas for a few hours.  Also, the wet snow stuck to trees and power lines.  There were scattered reports of tree limbs down and power outages, but nothing widespread.
