With colder air entrenched across the northern tier of the U.S., a jet streak dropped southeast out of Canada and a strong zone of frontogenetic forcing along the boundary of colder air resulted in a band of heavy snowfall, with brief rates up to 1 to 2 inches per hour through the Missouri River corridor. Winds were not excessive with the system, with no significant blowing and drifting impacts.  Snowfall generally reached 6 to 12 inches along the Missouri River, but dry air poised to the north rapidly dropped amounts to an inch or less north of Interstate 90.
