La Crosse, Wis. – Wisconsin drivers woke to dense fog across river valleys Wednesday, but sunshine will soon return with a fall warmup. Clear skies and calm winds will dominate into the weekend, keeping roads like U.S. Highway 53 and I-90 dry and safe for travelers.
According to the National Weather Service in La Crosse, temperatures will climb steadily through Friday, topping out near 79 degrees. The calm stretch continues Saturday and Sunday with highs around 80, a reminder that late September can still feel like summer.
