Episode Narrative A winter storm came out of the southwest United States and brought freezing rain and a little bit of snow to northeast Iowa from February 20th into the 21st. The freezing rain created ice accumulations that ranged from a tenth of an inch up to a quarter of an inch. Snow accumulations over the 2 days ranged from 1 to 4 inches. In addition to the freezing rain and snow, strong winds hit the area with sustained winds of 20 to 25 mph and gusts between 30 and 35 mph. Ice accumulations of a quarter of an inch were reported in Mitchell, Howard, Winneshiek, Clayton and Allamakee Counties. The ice accumulations were responsible for downed power and telephone lines, vehicle accidents and school cancellations. The highest reported snow amount was 3.6 inches in Fayette (Fayette County). As the freezing rain moved in, it was accompanied by some lightning strikes that sparked an explosion at a feed plant north of Oelwein (Fayette County).
Event Narrative Freezing rain developed across the county during the early morning hours of the 20th with ice accumulations up to a quarter of an inch on exposed surfaces. The freezing rain then changed over to snow with storm total accumulations of 1 to 2 inches through the 21st.
