Recommendation
Drive normally with routine caution. Best morning window: 10:00am-12:00pm, after the patchy fog burns off. Best evening window: 8:00pm-9:30pm, after storm chances end but before overnight fog thickens. If driving 7-9am, use low beams and add following distance; if a thunderstorm develops in the afternoon, slow down for wet pavement and brief visibility drops.
