Key Factors
- 01 Rain chances rise from about 1% earlier morning to 31% by 3–4 PM, and increase further after 5 PM (64%+) through the evening (75–90%+).
- 02 “Rain Showers Likely” persists through the evening (17:00–23:00), with “Showers And Thunderstorms” expected after 23:00, increasing hazard for drivers.
- 03 Patchy fog is specifically mentioned overnight after 11pm (between 11pm and midnight), which can sharply reduce visibility.
- 04 South wind 1–10 mph during the day with gusts up to 22 mph (daily forecast); gusty conditions can affect handling, especially for high-profile vehicles.
- 05 No active alerts are listed, but the combination of wet roads, thunderstorms, and late-night fog elevates overall driving risk.

Recommendation
Try to drive in windows with the lowest rain/visibility risk: Morning: 7:00–10:00 AM (mostly dry/partly sunny, low precip chances). Evening: 4:00–5:00 PM (rain is just starting—precip probability ramps up afterward and is much higher later). If you must drive later tonight, use extra caution after 10:00 PM due to high rain/thunderstorm likelihood and possible patchy fog after 11:00 PM.
