Key Factors
- 01 Patchy fog is expected before about 9am, which can cause localized reductions in visibility, especially between 7–9am.
- 02 After 9am, skies become partly to mostly cloudy with light winds (0–3 mph) and temperatures in the 70s to low 80s, which are favorable for driving.
- 03 There is only a slight (around 15–20%) chance of showers and thunderstorms this afternoon, so most areas will stay dry, with only brief, localized impacts if a storm develops.
- 04 Evening and late-night conditions are mostly clear to partly cloudy with light winds and no significant hazards indicated.
- 05 An Extreme Heat Watch is in effect for future days (starting Wednesday), but the dangerous heat conditions are not occurring today.

Recommendation
Avoid driving, if possible, during the patchy fog period from about 7:00–9:00am. A safer morning driving window is roughly 10:00am–12:00pm, and a safer evening window is around 7:00–9:00pm when conditions are calm and visibility is good.
