| Description: |
Areas of fog will continue overnight over most of northeastern Wyoming and western South Dakota. Patchy dense fog will occur through sunrise. With temperatures near freezing, elevated surfaces such as overpasses and bridges may become slick. Motorists should expect rapidly changing visibility, down to near zero at times. Remember to use your low beam headlights in fog, slow down, and provide plenty of braking distance between yourself and any vehicles in front of you. |
