Key Factors

Recommendation
Morning window — If you must drive, do so early between 7:00 AM and 10:00 AM, when rain chances are low (7–30%) and conditions are manageable. Evening window — After the storms clear, consider driving between 8:00 PM and 9:30 PM, when precipitation probability drops to near zero (3–7%) and winds are light — but be aware that patchy fog begins developing around 10:00 PM, so avoid driving after that time.
