Clearing skies, light winds and abundant low level moisture aided by recent rainfall has led to fog development early this morning. The fog will be dense in some areas, reducing visibilities to a quarter mile or less. In addition, due to the patchy nature visibilities are likely to change rapidly over short distances. Keep this in mind if traveling early this morning. When encountering dense fog be sure to slow down, keep your headlights on low beam and give yourself plenty of distance with other vehicles. Conditions should improve by daybreak as winds increase from the west and northwest ushering in slightly drier air. $$
