(EXTRACTED FROM FXUS63 KARX 051728) National Weather Service La Crosse WI 1228 PM CDT Wed Aug 5 2026 Issued at 1225 PM CDT Wed Aug 5 2026 Primary concern over the next 24 hours is the likelihood (70%) of fog across much of NE IA and SW WI tonight into early Thursday as light winds through the lower 4 kft of the atmosphere occur and skies clear. Expect IFR/LIFR conditions, particularly in river valleys, so have included this at LSE. Expect additional adjustments over the 2 TAF cycles. Otherwise, winds will generally light and variable until late in the period when southerly winds at 5 to 10 knots return. Ferguson
