Recommendation
If you must drive this morning, wait until after 8:00 AM EDT when the Dense Fog Advisory expires and visibility improves. For the safest morning window, aim for 9:00 AM–11:00 AM when skies are sunny, winds are calm, humidity has dropped, and fog has fully cleared. For evening travel, 6:00 PM–8:00 PM is your best window — winds are very light (5–7 mph), temperatures are comfortable (54–57°F), and precipitation chances remain negligible at just 1%.
