October 22-24, 1887 Snow Storm & Arctic Outbreak

From October 22 through October 24 1887, a significant early winter storm affected the Intermountain Region, Dakota Region, Upper Mississippi River Valley, and Great Lakes.  This winter storm produced 16 inches in Deadwood, Dakota; 12 inches in Merrill, WI; 10.5 inches in Grand Meadow, MN; 10 inches in Black River Falls, WI; 9.9 inches in Green Bay, WI; 8 inches in Gaylord, MI; and 2.5 inches in La Crosse, WI.

In the wake of this winter storm, a 1039 mb surface high moved southeast into the Northern Plains.  This system brought an unusually cold air mass southward into the aforementioned areas.  This air mass was more typical of late November or early December than mid October.  Some record low temperatures included:  -16 F in Deadwood, Dakota; -15 F in Billings, MT; 0 F in Aberdeen, Dakota; and 17 F in La Crosse, WI.

The map below shows the track of this low pressure system.
