Areas of fog, dense in some locations will persist through 8 AM. The dense fog will be especially common in and near river valleys and other low lying areas, and reduce visibilities under one quarter mile.
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.
