EF1 tornado in Trempealeau County, Wisconsin

This EF1 tornado developed southeast of Osseo and moved northeast, crossing into Jackson County near County Highway G. The tornado passed through a farm where damage occurred to the house and outbuildings. Otherwise, mainly tree damage occurred.

An intense storm system moved across the Upper Midwest on December 15th and produced a rare severe weather outbreak across western Wisconsin. Eight tornadoes occurred across parts of Trempealeau, Jackson and Clark Counties. Four of these tornadoes were rated EF2 and three EF1. The most substantial damage from the EF2 tornadoes occurred in Clark County. One tornado destroyed a home in the southwest corner of the county near Five Mile Creek west of Neillsville (Clark County). Another tornado caused extensive damage to farms and trees after moving through Stanley (Chippewa County) into the northwest corner of Clark County. An EF0 tornado passed through Perrot State Park (Trempealeau County) and damaged several homes on the west edge of Trempealeau (Trempealeau County). The other tornadoes largely moved through rural areas damaging trees, power lines and farm buildings. Because of the severe weather threat, the Rotary Lights display in La Crosse (La Crosse County) was closed for the first time in over 26 years where two temporary structures were destroyed.
