HANFORD, Calif. – The Central Valley woke under a blanket of dense fog this morning, its quiet streets and farm fields softened in pale gray light. Visibility in parts of Fresno, Kings, and Tulare Counties dropped below a quarter mile, creating hazardous travel from Los Banos to Visalia before sunrise.

According to the National Weather Service in Hanford, a Dense Fog Advisory remains in effect until late this morning, impacting much of the San Joaquin Valley, including Hanford, Lemoore, Corcoran, and Madera. Drivers along Highway 99, I-5, and rural county roads should reduce speed, use low beams, and allow extra braking distance. The fog may lift slowly near rivers and orchards, where trapped moisture lingers longer after dawn.

Once the fog clears, late-fall sunshine will quickly warm the region. Afternoon highs near 74°F will bring comfortable conditions through Sunday, with a light breeze and mostly clear skies. By Monday, the Valley sees a taste of early-November warmth—temperatures climbing toward the upper 70s before a midweek cool-down begins.

While the stretch remains dry for now, longer-range models hint at a possible shift by Thursday or Friday, with clouds and light rain brushing the Sierra foothills. It’s the kind of early transition pattern that often signals winter’s first push later in the month—something to watch as pre-Thanksgiving travel ramps up statewide.

Residents are encouraged to drive cautiously this morning and enjoy the calm, sunny afternoons that follow—ideal for fall yardwork, local markets, or early holiday decorating before wetter weather returns.
