La Crosse, Wisconsin – A pleasant Wednesday will quickly give way to a significant storm system, bringing widespread rain and potential thunderstorms to the region by nightfall. While daytime hours will be mostly calm with a high near 80 degrees, conditions are set to deteriorate significantly after the sun sets. The developing system will create wet and potentially hazardous travel conditions for those on area roads, including Interstate 90.
According to the National Weather Service in La Crosse, the chance for precipitation jumps to 90 percent on Wednesday night. Showers and a possible thunderstorm are expected, with new rainfall amounts between a quarter and half of an inch. This marks the beginning of a prolonged wet period that will define the weather for the remainder of the workweek and into the weekend. Residents should prepare for soggy conditions and slick roadways for the Thursday morning commute.
The unsettled weather pattern is expected to intensify through Thursday night. Another round of showers and thunderstorms could deliver an additional half to three-quarters of an inch of rain, increasing the risk of localized water ponding on streets and in low-lying areas. Residents are advised to ensure sump pumps are operational and that storm drains near their property are clear of debris to help mitigate potential issues.
This pattern of showers and storms will linger through Friday and into the weekend. Warnings remain in effect, and residents should stay updated on any new advisories issued by emergency management officials as the week progresses.
