Key Factors
- 01 Special Weather Statement notes areas of fog early this morning with locally dense patches and visibility potentially down to a quarter mile or less, creating brief early-morning visibility hazards.
- 02 The fog hazard appears time-limited to the early morning; by 7 AM onward, the hourly forecast shows partly to mostly sunny conditions with no explicit fog and no precipitation.
- 03 Temperatures are well above freezing all day (upper 60s in the early morning to low 80s in the afternoon), so there is no risk of ice or snow on roads.
- 04 Probability of precipitation is 0–3% throughout the day and evening, indicating essentially dry-road conditions.
- 05 Winds are light from the north (around 5–8 mph), posing no significant risk from strong crosswinds or blowing debris.
- 06 Evening and night conditions are partly cloudy and dry with mild temperatures, which are generally safe for driving.

Recommendation
Avoid or use extra caution if driving very early this morning while patchy dense fog is possible (especially around sunrise). Safer preferred windows for typical driving today are: MORNING: roughly 9:00 AM–11:00 AM, after fog has had time to dissipate and conditions are partly to mostly sunny and dry; EVENING: roughly 7:00 PM–10:00 PM, when it is partly cloudy, dry, and winds remain light.
