Key Factors
- 01 No active weather alerts are in effect for the forecast date.
- 02 Morning through afternoon is mostly sunny to partly sunny with very low precipitation chances (around 2% to 11%).
- 03 Temperatures remain well above freezing all day and evening, so ice-related road hazards are not indicated.
- 04 Winds increase through late afternoon and evening, with sustained speeds up to about 14 mph and daytime gusts as high as 24 mph, which may cause minor handling issues for some drivers.
- 05 A slight chance of rain begins after 5pm, with better chances of showers from about 7pm onward.
- 06 The highest-risk period today is late evening, especially 8pm to midnight, when rain chances increase and thunderstorms are possible near 11pm to midnight.
- 07 Patchy fog is mentioned only after midnight, so it is not a primary hazard during the forecast date but could affect very late-night travel near the day boundary.

Recommendation
Best morning driving window: 8:00 AM to 11:00 AM, when conditions are sunny, dry, and winds are light. Best evening driving window: 6:00 PM to 7:00 PM; avoid later evening travel if possible, especially after 8:00 PM, with the greatest caution from 11:00 PM to 12:00 AM due to showers and possible thunderstorms.
