Key Factors
- 01 Slight chance of rain showers around 10–11am (15%); thunderstorm chances increase from late morning into the afternoon.
- 02 Showers and thunderstorms are likely from about 2–6pm (probability ~57–59%) which can bring heavy rain, reduced visibility, and sudden slowing.
- 03 Evening period retains storm risk: 6–7pm (45%), 7–8pm (35%), and 8–9pm (25%) with conditions changing after sunset.
- 04 Road slickness risk is elevated due to repeated rainfall/thunderstorm likelihood through the evening; no snow/ice indicated, but wet conditions are probable.
- 05 Wind speeds are modest (generally 2–8 mph), so strong gust/crosswind risk is not indicated; the primary hazard is precipitation/thunderstorms.

Recommendation
Drive in the morning before storms ramp up—about 7–10am (mostly sunny, PoP 3–9%). Avoid the afternoon/evening storm window; for any travel late in the day, use 7–9pm only if storms are passing, since PoP drops from ~45% at 6–7pm to ~25% at 8–9pm.
