La Crosse, WI – Western Wisconsin residents will wake up to a chill as a brief fall cold snap grips the region Thursday morning, October 9. The National Weather Service in La Crosse warns that areas of frost could develop across low-lying and rural spots, potentially damaging tender vegetation and late-season gardens.
According to the National Weather Service, calm winds and clear skies will help temperatures dip into the mid-30s early Thursday before a return to sunshine and highs near 66°F. Gardeners are encouraged to cover plants or move containers indoors tonight to prevent frost damage.
Wednesday will bring bright sunshine and highs in the low 60s, while Thursday’s early frost gives way to a pleasant, sunny afternoon. By Friday, temperatures will rebound into the low 70s, making it a perfect setup for weekend leaf viewing or early Halloween decorating.
Looking ahead, La Crosse and surrounding areas, including Onalaska and Holmen, can expect mostly sunny skies Friday and Saturday, with mild highs in the mid-70s. Sunday could bring a 20–30% chance of light showers, but dry, comfortable conditions should return by Columbus Day.
Travelers along U.S. Highway 53 and I-90 should expect good driving conditions through the weekend, with clear skies and light winds dominating the forecast.
Stay weather-aware this week and take precautions to protect sensitive plants before Thursday’s early frost settles in.
