Key Factors
- 01 No active weather alerts for the forecast date
- 02 Patchy fog 7-9am with 93-97% humidity may briefly reduce visibility
- 03 Isolated showers and thunderstorms possible 9am-8pm (precip chance 14-23%), which could cause brief heavy rain or wet roads
- 04 Patchy fog expected to return overnight after 8pm as humidity rises toward 81%
- 05 Winds very light (1-5 mph), so no crosswind concerns
- 06 Temperatures 70-87F, so no ice risk
- 07 No numeric visibility data was provided, so fog density is uncertain

Recommendation
Driving is generally safe. Best morning window: 10am-12pm, after fog lifts and when shower chances are low (14-17%, partly sunny around 11am). Best evening window: 8pm-10pm, after the isolated storm threat ends and before overnight fog develops. If driving 7-9am or late night, use low beams and allow extra following distance. If a thunderstorm occurs, slow down and avoid flooded roads.
