California – Headlights cut through a gray wall across Los Angeles this morning as patchy dense fog drops visibility near or below one mile, slowing traffic on I-5, US-101, and surface streets across the basin.

According to the National Weather Service, fog lingers through late morning before gradual clearing pushes in by midday, setting up a warm afternoon with highs near 80°F. Light winds hold steady, but damp pavement and reduced sightlines continue to impact drivers into the late commute window.

Across East L.A., Glendale, and Pasadena, visibility improves steadily after 11 a.m., but pockets of thicker fog may hang in valleys and near low-lying roadways. Expect delays near freeway interchanges and shaded corridors. Keep headlights on, increase following distance, and allow extra time if traveling through mid-morning.

Clear skies take over tonight with temperatures dipping into the mid to upper 50s. By Tuesday and Wednesday, bright sunshine dominates again with highs pushing near 78–80°F, giving the region an early taste of summer. Air quality and pollen may rise with the warmth, so sensitive groups should take precautions.

Changes arrive late week. Increasing clouds Thursday signal a shift, with a slight chance of rain and isolated thunderstorms developing by Friday afternoon into Saturday. Roads could turn slick quickly after dry stretches, raising the risk for minor spinouts.

Stay alert for updates as conditions evolve into the weekend. Are you seeing dense fog in your neighborhood or smooth clearing? Let us know.
