Rounds of showers and thunderstorms will bring heavy rain to parts of the region through Thursday - which could result in flooding where the storms and heavy rain repeat, according to the National Weather Service in La Crosse.

In addition, there is a chance for a few strong to severe storms Thursday.

Friday brings the promise of a cooler, drier end to the work week.

Overview:

  • Weather mainly quiet through early evening (8 PM) across most of the area
  • 2 more rounds of storms expected into Thursday evening: first develops tonight and the second expected later Thursday afternoon and evening
  • Heavy rainfall remains the biggest weather risk - river rises likely with some flooding possible
