California – Fog drapes across Hanford this morning like a low gray sheet, softening headlights and muting fields along Route 41. Moist air clings to windshields, and visibility shifts from block to block—a classic early-December pattern that demands slow speeds and extra patience as travel builds.

According to the National Weather Service, dense and patchy fog lingers through late morning, especially near agricultural corridors where cool soil traps moisture. Travel may move slowly on rural roads, and drivers should allow extra time where visibility fluctuates. Even after the fog lifts, damp pavement can stay slick in shaded areas.

Skies brighten into the afternoon as the atmosphere stabilizes. Highs reach the upper 40s to mid-50s, eventually trending warmer into Saturday, when mostly sunny weather pushes temperatures toward 57°F. Calm winds dominate, keeping air quality relatively stable but allowing nighttime cooling to regenerate fog pockets. Friday morning may bring renewed localized fog before sunshine fills in.

While Hanford enjoys this quieter pattern, meteorologists are watching a broader December cold surge across the northern U.S. Models now hint at lake-effect snow from December 11–17, stretching from Minnesota to New York. Anyone planning early holiday travel through major Midwest hubs should monitor developing storm tracks, as quick temperature drops often lead to flash-freeze risks on untreated roads.

Locally, expect chilly evenings in the upper 30s to low 40s, with fog reforming before dawn each day. Conditions improve fastest between 10 a.m. and 1 p.m., when sun angle begins to clear low stratus layers. Keep low beams on during morning commutes and watch for slow-moving farm vehicles emerging from fog banks.
