Key Factors
- 01 Dense Fog Advisory: visibility around 0.25 mile or less until 8:00 AM EDT (major hazard for driving).

- 03 Slight chance of showers and thunderstorms from about 2:00 PM to 5:00 PM (peak hourly PoP ~21–23%), which can create brief heavy rain/road slickness and reduced visibility.
- 04 Early evening has a slight chance of rain showers (about 6:00–8:00 PM, PoP ~15–16%).
- 05 Wind increases through the afternoon (W winds up to ~12 mph; daily gusts reported up to 22 mph), which can affect vehicle handling, especially for high-profile vehicles.
