Pacific Coast and Peninsula: A warm beach day is setting up for Highway 1 from Half Moon Bay to Davenport, with morning fog making way for dry, light winds off the coastal mountains and temperatures in the mid-70s.Residents west of Sutro Tower will also get in on this warm-up, with the Sunset and Richmond districts set to get to the lower 70s before sunset. This air will chip away at the clouds from 2-4 p.m. Balmy, dry winds from the east will descend over downtown, the Castro, Haight-Ashbury and Mission Dolores this afternoon. The big story is, of course, the warm-up. Winds will be a tad lighter today along Golden Gate Park and the Embarcadero, with gusts blowing at only 10 mph. Look for afternoon skies littered with a mix of cloud types - from dangling cirrus to puffy cumulus. While there will be some patchy morning fog along Highway 1 and the Presidio, most of Tuesday’s cloud cover will be from high clouds. San Francisco: Tuesday’s clouds are going to be a little different from what we’ve seen over the past few weeks.Northern California and the Sacramento Valley will also be getting in on the heat as well, with cities like Chico and Sacramento expected to see their temperatures go up by 5 to 10 degrees. This warm-up will affect the entire Bay Area as 3 to 5 degrees of warming comes to the coast and 7 to 11 degrees of warming will seep into the valleys of the North Bay, East Bay and South Bay by Tuesday afternoon. These northeasterly winds will shove the marine clouds back out to the coast and usher the arrival of considerably warm and dry air to the entire region for the first time since the Labor Day heat wave.Ī big warm-up is coming to the Bay Area on Tuesday, with cities on the coast expecting highs that will run 3 to 5 degrees warmer than Monday while inland cities like San Jose and Santa Rosa may see as much as 7 to 11 degrees of warming. The winds coming off San Francisco Bay on Tuesday morning will feel like they’re moving in reverse compared to the west winds that residents in San Francisco, Oakland and Richmond have experienced over the past several weeks. #cawx /JFFzOvifHl- Darren Peck October 17, 2022 A subtle offshore breeze this morning is pushing the clouds OUT through the golden gate. You don't see this often! is moving backward this morning How is this even possible you ask?! Early Halloween spookery?! Nah. The new position for the high-pressure system will quickly propel warm, dry air south to California, shearing off most of San Francisco Bay’s late-season fog. #CaWx /t5kI9tbrLQ- Gerry Díaz October 17, 2022 The good news: California's stable air will fizzle it out, leaving only high clouds for the Bay Area in its wake. Plenty of unstable air over the open waters some 400-500 miles off the coast this morning flaring up thunderstorms.️ Weather models expect the ripples from the storm to cast waves of energy toward the Pacific Northwest, moving the hot, high-pressure system that’s been sitting over the region a couple hundred miles to the south. But eventually, the low-pressure system withered away, and that balancing act is falling apart.īut a developing storm, some 500 miles away from the California coast, is set to cause a domino effect that will eventually offset the high-pressure system in the Pacific Northwest. This created a balance where the two weather systems relied on each other to stay in place. Last week’s weather was dominated by a rex block pattern, meaning that a high-pressure system was stuck over the Pacific Northwest while a low-pressure system was immediately to its south. So why is so much warm air coming in from the north anyway?
