(EXTRACTED FROM FXUS63 KARX 151045) National Weather Service La Crosse WI 545 AM CDT Wed Jul 15 2026 Issued at 545 AM CDT Wed Jul 15 2026 Fog has formed in many river valleys across the region. This fog will dissipate over the next few hours. After the fog dissipates, smoke from Canadian and northern Minnesota wildfires moves in this afternoon and lingers through the day on Thursday. As a result, some locations may see reduced visibilities due to the smoke. There remains not enough confidence to put smoke in the TAFs at KLSE and KRST. If confidence grows that this smoke will lower visibilities enough at both airports then smoke will be put in the TAFs. Winds are light and variable for the forecast period. Cecava
