Summary
A Dense Fog Advisory was in effect early this morning (until 8:00 AM EDT) with visibility as low as 1/4 mile, but conditions have since improved significantly. The rest of the day brings mostly sunny skies, mild temperatures, light winds, and virtually no precipitation risk.
Key Factors
- 01 Dense Fog Advisory was active until 8:00 AM EDT with visibility as low as 1/4 mile, creating hazardous early-morning driving conditions.
- 02 Post-fog conditions are favorable: mostly sunny to sunny skies throughout the day with 0% precipitation probability.
- 03 Temperatures range from 45–58°F during the day — well above freezing, eliminating ice risk.
- 04 Winds are light to moderate (7–13 mph NW during the day, tapering to 2–7 mph SE overnight) — no significant crosswind hazard.
- 05 Evening brings increasing cloud cover (partly to mostly cloudy) with a slight precipitation chance (up to 8% overnight), but no meaningful driving hazard.
- 06 Humidity is elevated early (86% at 7 AM) but drops steadily through the afternoon (40% by 3–5 PM), supporting fog clearing after 8 AM.
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%.
