Key Factors
- 01 Chance of showers and thunderstorms this morning (precipitation probability roughly 23–35% from 7–9am).
- 02 Storms today could produce heavy rain (daily forecast: “Some of the storms could produce heavy rain”).
- 03 Late afternoon/evening thunderstorm risk increases (around 5–7pm with precipitation probability up to ~20%, and ~26–29% from 7–9pm).
- 04 Lower visibility/road spray risk is not quantified in the provided data (no visibility values given), so confidence is reduced, but wet roads are likely when storms occur.

Recommendation
Safer to drive during the window when rain chances are lowest: 10:00am–12:00pm (mostly cloudy; precipitation probability drops to ~2–12%). Use extra caution in the evening; if you must travel, 9:00pm–10:00pm has only slight chance rain showers (~20–29%), but be prepared for developing showers and reduced traction.
