Key Factors
- 01 Thunderstorm timing risk: slight chance after ~5pm, increasing to showers/thunderstorms likely from ~8pm through at least ~2am (peak risk window: 8pm–2am).
- 02 Heavy rain potential: forecast notes some storms could produce heavy rain (new rainfall amounts between 1/4 and 1/2 inch possible overnight).
- 03 Wind/gusts: winds rise to 10–13 mph with gusts up to 25 mph, which can worsen handling and visibility in storms (especially for high-profile vehicles).
- 04 Reduced travel reliability at night: lower visibility/road spray expected during thunderstorm hours (no explicit visibility value provided, so impact is inferred from precipitation/TS likelihood).

Recommendation
Safer to drive during two calmer windows: (1) Morning: 7:00–11:00 AM. (2) Evening: avoid the main storm period; if you must travel, aim for 6:00–7:00 PM before the higher likelihood window starts around 7–8 PM (otherwise postpone until after storms pass).
