Current webcams and surface observations show locally dense fog from the Colorado border to the city of Cheyenne, with visibility down to one quarter of a mile. This fog is expected to linger for the next several hours, with visibilities fluctuating between one quarter of a mile and 4 miles through the afternoon.
If traveling across Laramie County, please slow down, use your low beam headlights, and leave plenty of distance ahead of you. Be prepared for sudden drop in visibility.
