| Area Forecast Discussion National Weather Service San Francisco CA 838am PST Sunday Jan 18 2026 ...New UPDAT Marine .KEY MESSAGES... Updated at 1206am PST Sunday Jan 18 2026 - Dry weather, cool mornings, and warm afternoons this week - Morning fog possible across the Delta and interior valleys Issued at 837am PST Sunday Jan 18 2026 Seeing less fog coverage this morning across the North Bay Valleys, yet in the interior East Bay Valleys and Delta we are seeing similar conditions as yesterday morning. As of this writing, both Concord and Byron airports are reporting visibilities of less than 1/4 mile. In addition, mid to high level clouds continue to stream across the region. With day time heating, fog is forecast to lift and mix out by early afternoon across the East Bay. Otherwise, no updates are anticipated at this time as the forecast remains on track. .SHORT TERM... Issued at 1206am PST Sunday Jan 18 2026 (Today and tonight) High clouds continue to blanket the Bay Area and Central Coast tonight. These elevated moisture is concentrated between 27,000 and 37,000 ft. The main impact of these clouds is reducing radiational cooling to space. They do this indirectly by absorbing and re- emitting thermal energy back to the surface. Valley temperatures are between 1-5 degrees warmer than this time last night. However this degraded cooling hasn't been enough to stop the Tule Fog from forming in the Central Valley. Dense fog is being reported from Sacramento to Hanford, including the Sacramento River Delta and surrounding areas. Concord has been reporting dense fog for several hours, but no other airports in our cwa have joined in. The SFO-WMC gradient is -8.2 mb, substantially weaker than 24 hours ago. This is bringing much lighter offshore winds, with Mt. St. Helena now gusting around 5 mph, vs nearly 50 mph last night. Outside of the weaker mountain winds, today will be nearly identical to yesterday. Expect a crisp morning with some localized fog, colorful sunrise thanks to high clouds, warm afternoon with filtered sunshine, and another great sunset. Enjoy the weather today, it doesn't get much better this time of year. Long Term Issued at 1206am PST Sunday Jan 18 2026 (Monday through Saturday) The ridge is gradually weakening, but nice weather will continue in the long term period. The 500 mb height is continuing to very slowly lower following the near record of 5,900 m last Wednesday. This trend will continue through the week, and it's expected to fall below 5,700 m by Friday. That's near the daily average for this time of year. A similar story is unfolding with the 850 mb temperature, dropping from near record territory to near normal by the end of the week. This is being caused by a trough over the North Central Pacific spitting out a cut-off upper level low late this week. All indications are that this system will have a very weak surface reflection and will stay offshore through the weekend, but it will take a bite out of the ridge. While it's still possible for a few drops to fall, the trend has been clear that this system will not bring significant rain to the cwa. It will, however, serve as a catalyst to usher in a more active pattern the following week, which could bring us some long- awaited rain for the last few days of the month. Marine (Today through Friday) Issued at 837am PST Sunday Jan 18 2026 Gentle to moderate northeast to east breezes continue across the San Pablo Bay, the Delta, and through the Golden Gate through Wednesday while light to gentle northeast to north winds continue across the rest of the coastal waters. Later this week, the ridge should break down as a weak cutoff low approaches, allowing winds to increase and shift to the northwest and west. Low seas up to around 6 feet continue through the middle of the week as a northwest swell builds. NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...None.
