Key Factors
- 01 Chance of rain showers beginning around 2pm, increasing through late afternoon (hourly POP peaks around 3–4pm and remains elevated through about 6pm).
- 02 Thunderstorms are possible from about 5pm–8pm (hourly: “Chance Showers And Thunderstorms”).
- 03 Patchy fog is forecast after about 8pm (daily period 2), which can significantly reduce visibility while driving.
- 04 Wind is light to moderate (mostly 7–9 mph), so wind alone is not the main hazard; precipitation/visibility are.
- 05 No visibility or precipitation intensity values are provided, so timing of the worst conditions could vary, but the storm/fog periods are clearly indicated.

Recommendation
Safer to drive in the morning: 7:00am–11:00am, when conditions are mostly sunny with very low precipitation chances. Avoid evening travel if possible—conditions worsen after ~5pm with thunderstorms, and after ~8pm patchy fog may form; if you must drive, use extra caution and slow down starting 8pm.
