Recommendation
Drive normally, but use low beams and extra following distance if you must travel before 9am due to patchy fog. Safest morning window: 9:00am-12:00pm. Safest evening window: 7:00pm-10:00pm, after the afternoon thunderstorm chance ends and before overnight fog forms after midnight. Carry water and check coolant/tires given the heat advisory.
