Unseasonably Cold Storm Threatens Scattered Thunderstorms Through Thursday
An unseasonably cold storm system is swirling directly over Northern California, generating a bizarre mix of rough seas, mountain gales, lightning and local rain. Tonight & Wednesday: Isolated Storms & Dangerous Coastlines The Storm Threat: Scattered showers and isolated thunderstorms are actively moving through the North Bay and East Bay with the highest lightning threat near Napa and Livermore through tonight. Mountain Gales: Gusts of 30–40 mph (and up to 50 mph) along the coast and across the North Bay & East Bay hills tonight. Dangerous Seas: Powerful gale-force winds are building massive, rough waves of 12-15 feet through Wednesday morning. Boaters and beachgoers must use extreme caution. Beach Hazard Statement in effect until 9 AM Wednesday. Wednesday: We do it all over again. Temperatures will stay chilly, only in the 50s and 60s at the coast and 60s to low 70s inland. Another round of scattered showers and a few weak afternoon thunderstorms will pop up, especially for the interior Bay Area.

Beach Blanket Chills: Coast stays locked in the 50s for the Holiday Weekend
Sunday: Expect carbon-copy weather. The only change is that the North Bay fog will clear out a little earlier in the morning compared to today. West winds 10-20 MPH Memorial Day Monday: The marine layer gets even deeper, pushing thick fog way inland. Widespread morning clouds will be slow to clear. Expect cool, cloudy beaches in the 50s, bayshores in the low 60s, and only the furthest interior spots reaching the 70s. Tuesday: A low-pressure system is now expected to pass to our north, which will cut off our ocean air and trigger a dry, northwesterly breeze. This wind shift will cause temperatures to warm on Tuesday, kicking off a modest warming trend.

Holiday Cool-Down: Widespread Fog Floods the Bay for Memorial Day Weekend
Tonight: The fog is moving fast. Thick low clouds are currently spilling through the Petaluma Gap, the Golden Gate, and across the Monterey Bay region. Only the highest mountain peaks and the far eastern edge of Contra Costa County will escape the gray blanket by morning. Saturday & Sunday: Expect a gray start to the holiday weekend. Low clouds will be slow to clear each morning, keeping afternoon temperatures very seasonal. Expect upper 50s to mid-60s on the coast, 60s to low 70s around the Bay, and upper 70s to mid-80s far inland. Patchy coastal drizzle is possible both nights. Memorial Day Monday: We start mild, but a cold front approaches late in the day, cranking up the afternoon ocean breezes. No Coastal clearing in the 50s, unseasonably cool Inland in the low to mid 70s. Breezy. Tuesday: The cold front sweeps through from north to south. It will bring much cooler temperatures and a round of widespread drizzle or light rain to the Bay Area and Central Coast. Enjoy your holiday weekend, but be safe!

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.

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
