Overview
- Low stratus and fog continue across the Central Valley, Delta and Bay Area, while sunshine dominates above roughly 1,500 feet and along the coast.
- Daytime highs in many valley locations remain in the mid to upper 40s, about 10 degrees below average, as parts of the Sierra climb into the upper 50s to low 60s.
- Sacramento has reached 19 consecutive days without measurable rain since Nov. 20, and outlooks show no significant precipitation in the seven-day forecast.
- Meteorologists tie the tenacious cloud deck to a stable high-pressure ridge steering storms into the Pacific Northwest, with the overcast persisting for at least 16 days.
- Fog chances run near 80% in North and East Bay valleys, 50% in the Santa Clara Valley and 30% on the bay side of San Mateo County, with SFO historically prone to reduced morning visibility under certain winds.
