Key Factors
- 01 NWS Special Weather Statement: areas of fog developed early this morning; some fog may become locally dense with visibility of a quarter mile or less.
- 02 Hourly relative humidity is very high early (93% at 07:00, 90% at 08:00, 84% at 09:00) then falls through the morning—consistent with fog becoming less widespread after mid-morning.
- 03 No precipitation, temperatures well above freezing, and only light north winds (5–8 mph) for the rest of the day reduce other roadway hazards.

Recommendation
Avoid nonessential driving during the early-morning fog—particularly before 10:00 AM local time when visibility may be rapidly changing. Safer morning window: 11:00–12:00 (fog likely dissipated). Safer evening window: 7:00–8:00 PM (dry, partly cloudy, light winds). If you must drive during fog, use low beams, slow down, and increase following distance.
