WIDESPREAD FOG WILL CONTINUE THROUGH THIS EVENING... Very light wind and mild, moist air flowing over the cold and in some areas, snow-covered ground, will lead to widespread fog with visibility between one half of a mile and 2 miles in the valleys for the rest of the day and early tonight. Locally dense fog with visibility under one quarter of a mile will occur across the ridges. Use caution if your travel route will cross the higher terrain where the visibility could be very poor near the ridge tops. Slow down and allow plenty of braking distance between you and the vehicle ahead.
