A strong upper level wave lifted northeast from the Texas Panhandle early on March 9, reaching the western Great Lakes as an intense closed low. This system included a leading surge of warm air, allowing precipitation to become rain or light freezing rain over a large area, with many locations receiving a few hundredths to two tenths of an inch ice accumulation before colder air wrapped in behind and transitioned precipitation to snowfall. Brief periods of heavier snowfall due to marginally unstable air off the surface led to accumulations of 2 to 6 inches north of Interstate 90 along with travel disruptions, with generally a trace to 2 inches south; the exception being parts of northwest Iowa which received 2 to 4 inches. As the surface low pressure moved across Iowa by later in the afternoon and evening of March 9, northwest winds increased to a gusty 30 to 45 mph.
