Key Factors
- 01 Patchy fog from 6:00 AM to about 10:00 AM (daily forecast explicitly: “Patchy fog before 10am”).
- 02 Fog persists/returns late: patchy fog between 11:00 PM and 3:00 AM (daily forecast).
- 03 Between 3:00 AM and 5:00 AM there is a slight chance of rain, followed by “chance of rain and patchy fog” toward morning; precipitation type is not specified (rain vs. possible light freezing), so slickness risk is uncertain but elevated.
- 04 Near-freezing temperatures overnight (about 38–36°F from midnight through early morning), which can worsen any damp-road conditions.
- 05 Low wind speeds overall, but the main driving hazard is visibility (fog), not wind.

Recommendation
Use the safer windows for driving: Morning: 10:00 AM to 12:00 PM when fog clears and conditions are mostly cloudy/partly sunny. Evening: 6:00 PM to 8:00 PM when it’s mostly cloudy; avoid late-night driving after 11:00 PM due to patchy fog and increased precipitation chances early morning.
