Details
Areas of fog, dense in some locations will persist through 8 AM.
The dense fog will be especially common in and near river valleys

If traveling this morning, be prepared for fog that could bring
sudden and significant reductions in visibility over short
distances. If you encounter dense fog, slow down, give yourself
plenty of braking distance between other vehicles, and be sure to
keep headlights on low beam. Be especially cautious in school zones.
Conditions should improve between 8 AM and 9 AM.
