Winter Storm Warning Minnesota, Wisconsin | Effective 03/13/2026 14:03

...MAJOR WINTER STORM SATURDAY NIGHT INTO MONDAY MORNING... .A prolonged, high-impact winter storm affects the region Saturday night through Monday morning. Highest snow totals in excess of 12 to 18 inches are favored north of Interstate 90 with some locales north of Highway 10 approaching 24 inches. Along Interstate 90, a wintry mix of snow, freezing rain, and sleet makes it difficult to pin down exact snow and ice amounts, but impacts are warranting of a winter storm warning. Across northeast Iowa and southwest Wisconsin, snow does not look to arrive until Sunday afternoon, so the winter storm watch is maintained until further details can be ascertained. Increasing winds Sunday afternoon and night should result in whiteout conditions for exposed locales and an upgrade to a blizzard warning is likely once the exact threat area is determined. Regardless of exact snow amounts, expect major travel impacts regionwide with some roads possibly impassable, especially in wind-prone areas. * WHAT...Heavy snow, mixed with sleet and freezing rain. Total snow accumulations between 6 and 12 inches with locally higher amounts. Ice amounts around one tenth to three tenths of an inch. Winds gusting up to 50 mph may result in blizzard conditions later Sunday into Monday morning. * WHERE...Portions of southeast Minnesota and central, southwest, and west central Wisconsin. * WHEN...From 7 PM Saturday to 1 PM CDT Monday. * IMPACTS...Travel could be very difficult to impossible. Widespread blowing snow could significantly reduce visibility. The hazardous conditions could impact the Monday morning commute. Gusty winds could bring down tree branches.
