Key Factors
- 01 Forecast mentions thunderstorms with some storms possibly severe and producing heavy rain (day and night periods).
- 02 Rain/thunder chances increase through the day, with hourly precipitation probabilities rising to ~40–52% by 3–7 PM and ~55–60% from about 7–10 PM.
- 03 Expected rainfall amounts are substantial: ~0.25–0.5 inch during the day and ~0.5–0.75 inch at night, which can create water on roadways and localized flooding in heavy downpours.
- 04 No visibility data is provided; heavy rain and thunderstorms can rapidly reduce visibility, adding uncertainty and increasing risk.
- 05 Winds are light (generally 2–6 mph), so the main concern is heavy rain/thunderstorms rather than wind.

Recommendation
If you must drive, aim for a morning window around 7:00–11:00 AM (lower storm risk; only slight-chance showers). Avoid driving during the highest-risk period roughly 12:00 PM–11:00 PM, especially 4:00–10:00 PM when storms are most likely. For an evening option, the relatively safer slot is late evening around 11:00 PM–12:00 AM when storm chances ease somewhat (still use caution for lingering wet roads and isolated thunderstorms).
