PATCHY DENSE FOG POSSIBLE... Areas of fog will develop across the region with visibilities decreasing to 1 to 3 miles. The fog may become locally dense, further reducing visibilities to less than one-half mile at times. Motorists encountering the fog should slow down, use your low beam headlights and allow for extra braking distance between you and the vehicle ahead. By mid-daytime morning, the days insolation and an active southwest wind should be enough to quickly dissipate the fog. && dch
