An early winter storm produced 6 to 9 inches across portions of central and southern Minnesota during the morning and late afternoon of Tuesday, October 20th. A weak surface trough moved across the Upper Midwest with modest warm air advection ahead of it. Initially, precipitation was light but increased by the late morning and afternoon as both higher than average Precipitable Water values were ingested into the system and a dual upper jet core was maximized across Minnesota. This allowed for a few hours of higher snowfall rates and led to isolated 8-9 inch totals where banding of these higher snowfall rates was located.  The snow set records in some locations for being so heavy so early in the season.
Some of the higher snowfall totals from this system include:
9.5 inches east of New Prague.
9.1 inches southwest of Apple Valley.
A swath of 8.5 to 9.0 inches between Prior Lake and Rosemount in Scott and Dakota Counties.
