Wisconsin — Light flakes and a biting chill are greeting parts of the La Crosse area this morning, where temperatures near 37°F and early snow showers are creating slick spots and reduced visibility for drivers heading out.
According to the National Weather Service in La Crosse, temperatures at or below freezing combined with light winds are creating high frost potential early, with widespread sub-30°F lows expected by early Monday. That sets the stage for a significant frost and freeze risk across southeast Minnesota, northeast Iowa, and western Wisconsin.
Across La Crosse, Onalaska, and Winona, isolated snow showers and flurries may mix with sprinkles through the morning before skies gradually clear. Roads remain mostly wet, but bridges and shaded stretches along Highway 53 and I-90 could turn slick if temperatures dip quickly. Plan extra time if traveling and watch for brief visibility drops.
The bigger concern builds into tonight and early Monday, when temperatures fall to around 25°F. Widespread frost will form, threatening early-season crops, gardens, and outdoor plumbing. Residents should cover plants and bring sensitive vegetation indoors before evening.
Flooding also remains a concern along area rivers, with elevated levels continuing into early week. Avoid low-lying roads near waterways and never drive through flooded areas.
By Tuesday, a dramatic warm-up begins. Highs jump to 73°F under sunny skies, followed by 76°F Wednesday. Meteorologists are tracking this sharp temperature swing, which may lead to showers and thunderstorms by Thursday afternoon into Friday. While severe weather is not certain, gusty winds and brief heavy rain are possible.
Take action now: prepare for freezing temperatures, allow extra travel time, and stay alert near rivers.
Cold conditions ease after Monday morning, but additional alerts remain possible as weather patterns shift.
