Key Factors
- 01 A Special Weather Statement reports fog early this morning, with some areas possibly having visibility of a quarter mile or less.
- 02 Hourly and daily forecasts otherwise show dry conditions, with 0-3% precipitation chances through the day and evening.
- 03 Winds remain light, generally 5-8 mph from the north, which should not create major driving issues.
- 04 Temperatures stay well above freezing, so there is no ice or winter-weather risk.
- 05 The exact duration of the fog hazard is unclear from the alert timing, so early morning travel carries some uncertainty.

Recommendation
Avoid or use extra caution for early morning driving, especially before about 9:00 AM, due to possible dense fog and sudden drops in visibility. A safer morning slot is 10:00 AM-12:00 PM, and a safer evening slot is 6:00 PM-9:00 PM when conditions remain dry with light winds.
