The National Weather Service-La Crosse has issued a winter storm watch for Mower County Tuesday evening through Wednesday morning.

The system is expected to produce 4 to 6 inches of heavy wet snow. Most of the snow accumulation is expected over higher terrain and on grassy surfaces. Visibility may be reduced to under one mile at times, according to the NWS.

Other counties under a watch include Olmsted, Winona and Fillmore.

The winter storm watch means there is a potential for significant snow, sleet or ice that may impact travel.
