Key Factors
- 01 Special Weather Statement notes areas of fog early this morning, with some fog locally dense and visibility down to a quarter mile or less.
- 02 Fog is most likely in the early morning hours: patchy fog from 7:00 AM–8:00 AM and again 8:00 AM–9:00 AM (then trending to mostly sunny after 9:00 AM).
- 03 Hourly forecast shows slight to chance showers/thunderstorms from about 1:00 PM onward (15–25% daytime), which can bring brief heavy rain and sudden visibility changes.
- 04 Heat Advisory is in effect until 8:00 PM, which can contribute to driver fatigue and reduced alertness (even though it’s not a direct roadway hazard).
- 05 No specific wind gusts or visibility numbers are provided for the afternoon/evening thunderstorm period, adding uncertainty.

Recommendation
If possible, avoid the fogiest window and plan travel after visibility improves—safer morning driving is roughly 9:00 AM–11:00 AM. For the evening, consider driving earlier—roughly 6:00 PM–7:00 PM—before the later period of ongoing low-level thunderstorm chances (20% or so through the early evening hours).
