Key Factors
- 01 Patchy fog is forecast from 7:00 AM to 9:00 AM, with very high humidity (93-97%), which may reduce visibility during the morning drive.
- 02 Isolated showers and thunderstorms are mentioned from about 9:00 AM through 8:00 PM, creating localized wet-road and brief visibility hazards even though precipitation chances stay relatively low (generally 15-20%).
- 03 No active weather alerts are in effect.
- 04 Winds are light all day (about 1-5 mph), so strong-wind driving hazards are not expected.
- 05 Temperatures remain warm well above freezing, so there is no ice or winter-weather risk.
- 06 Visibility values are not provided, so the severity of the fog and any storm-related visibility reduction is somewhat uncertain.

Recommendation
Safe for most drivers with caution. Avoid or delay driving during the foggiest morning window from 7:00 AM to 9:00 AM if possible. A safer morning slot is 11:00 AM to 12:00 PM. For evening travel, the safer slot is 8:00 PM to 10:00 PM after isolated thunderstorm chances decrease. If driving between 9:00 AM and 8:00 PM, watch for brief localized showers or thunderstorms and reduce speed on wet roads.
