Key Factors
- 01 Thunderstorm threat ramps up after 18:00: Chance of precipitation increases from 14% (17:00-18:00) to 28% (18:00-19:00), 56% (20:00-21:00), and up to ~60% overnight (daily guidance).
- 02 Most hazardous evening window appears roughly 19:00-01:00, with “showers and thunderstorms likely” around 20:00-21:00 and continued “chance” periods afterward.
- 03 Gusty winds with storms: daytime gusts up to 28 mph; overnight daily guidance notes gusts up to 26 mph, which can be hazardous for high-profile vehicles.
- 04 Reduced driving conditions likely during storms (implied by thunderstorm/showers), but no explicit visibility or rainfall intensity values are provided.

Recommendation
Generally avoid driving during the stormiest period. Safer time in the morning: 07:00-10:00 (mostly sunny; very low precipitation chances early). Safer time in the evening: 17:00-18:00 (before thunderstorms become likely; only a 14% precipitation chance). After 19:00, especially 20:00-01:00, consider delaying trips or using extra caution if travel is necessary.
