The Fog Fights Back: Marine Layer Expands Inland for the Holiday Weekend
The weather tug-of-war is shifting and our natural air conditioning is gaining ground. The marine layer has deepened to around 1,000–1,500 feet, sending fingers of thick fog into the interior valleys. The Forecast: Day-by-Day Tonight: The fog is expanding. Stratus is already hugging the immediate coast, moving through the Golden Gate toward Berkeley. Expect a gray, souggy blanket to fill most inland valleys by early Friday morning . Friday Afternoon: Temperatures begin to drop across the board. The coast stays crisp in the upper 50s to low-60s, while inland valleys drop from the 90s back into the upper 70s and mid-80s. The Memorial Day Weekend: The marine layer deepens even further to 1,500 feet. Expect seasonal, comfortable temperatures alongside the threat of late-night and early-morning coastal drizzle.

"Weekend Weather Danger: High Fire Risks Inland, Turbulent Conditions at the Coast
A dry "inside slider" is dropping south from the Pacific Northwest tightening pressure gradients. This setup has triggered a Red Flag Warning for Solano County Saturday - Monday. Winds: North winds will track 20 - 30 mph with gusts 35 to 45 mph (and up to 50 mph around the Delta gap). Any fire that sparks this weekend will grow and spread rapidly. High temps 60s to low 80s. Outdoor burning is strictly discouraged and drivers should avoid parking vehicles on dry grass. A Beach Hazards Statement for dangerous coastal conditions through Monday. Special Warning: Bay to Breakers participants to completely stay out of the water at Ocean Beach this weekend. High tidal swings could also trap walkers against the cliffs. Stay off the rocks and jetties! Coastal Flood Advisory 10 PM SATURDAY - 3 AM TUESDAY. WHAT: Up to 1.0 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. WHERE: Bayshore locations along the San Pablo Bay. WHEN: From 10 PM Saturday to 3 AM Tuesday.

The KTVU Weather Department talks about El Nino and the Bay Area
An El Niño event has an 82% probability of developing by July 2026 and a 96% chance of lasting through the Northern Hemisphere winter, with potential for a "super" El Niño. This pattern is expected to suppress Atlantic hurricane activity while increasing global temperature records and enhancing precipitation in the southern U.S

Friday & Weekend: The calm weather ends tomorrow as a strong wind machine turns on. Sunny skies with cooler temperatures. West winds increase 20 - 30 mph with the potential of a Wind Advisory for the weekend. Hazardous Seas: Very strong winds over the ocean will create dangerous marine conditions starting Friday. Boaters and swimmers should use extreme caution. Gusty Land Winds: Expect a big jump in winds along the immediate coast and up in the mountains through the weekend. Elevated Fire Warning (Weekend through Monday) The Dry Out: A very dry air mass is moving in. Humidity levels are going to plummet during each day and will stay unusually low at night.

El Niño Explainer: Conditions return this year
El Niño is a natural recurring climate pattern that has its origins in the Pacific Ocean. The pattern will return this year as conditions change. KTVU Chief Meteorologist dives in on what this means.

One day summer sizzle
Looking ahead: We are in a tug-of-war between high pressure trying to heat things up and the "marine layer" (our coastal fog) trying to keep us cool. While Monday is still technically the warmest day of the week, the ocean air is winning more battles than expected, keeping temperatures a bit lower than original "heatwave" predictions. Monday Forecast: The Warmest Day The Forecast: It’s a "tricky" one. If the clouds clear out early, inland areas will reach the mid-80s to low 90s. However, if the fog lingers like it did today, we could stay several degrees cooler. The Coast: Expect much cooler conditions in the 60s and 70s thanks to a persistent ocean breeze and shallow fog. Heat Risk: The risk of heat-related illness is now less widespread than previously thought, but it will still feel quite toasty in the far interior valleys.

Mother Nature bringing a mixed bag for Mother' s Day
After a mostly cloudy, drizzly start to the day, partly cloudy to mostly sunny conditions can be expected by afternoon for Mother's Day Sunday. Afternoon highs will range from low 60s near the coast to mid 80s inland. The warming trend will peak on Monday when inland cities soar into the low 90s.

"May Gray" AND sunshine for Mother's Day
Saturday Evening & Sunday: Heating Up Tonight: Expect the "May Gray" to return as coastal fog and low clouds push into the valleys overnight. You might even see some mist or light drizzle by Sunday morning. Sunday: Clouds will clear out quickly in the morning, giving way to plenty of sunshine. Highs will be a little warmer than Saturday, reaching the mid-80s to low 90s in far inland spots, while the coast stays refreshed in the upper 50s and 60s. Monday: The Peak Heat Monday will be the hottest day of the week across the region. Temperature Ranges: Interior Valleys: Low to upper 90s. Inland Areas: Mid-80s to low 90s. Near the Coast: Low 70s to mid-80s. Heat Risk: Much of the interior is under a Moderate Heat Risk. This can be dangerous for people sensitive to heat, like children, the elderly or those working outdoors. The heat won't last long. Starting Tuesday, temps begin to dip, though they will still be warmer than average for this time of year. Big Shift: Chance of drizzle or light rain midweek!
