Synopsis
Mild Sunday afternoon with a cool night, and dry weather conditions. Locally gusty offshore winds at some of the highest peaks will continue to subside this morning. Most of the San Francisco Bay Area
and Central Coast is forecast to remain dry through much of next week before rain chances potentially return for the first weekend of March.

as of 08:51am PST Sunday...Visible satellite imagery is starting us off with mostly clear skies and a handful of high-base clouds gliding over the interior that will gradually travel out to sea as north/northeasterly mid-level flow carries over into the afternoon. Winds continue to weaken along the foothills and over the Mt. Diablo and Mt. St. Helena stations this morning although are still observing some noteworthy gusts ranging around 50-60mph above 2500 ft. All in all, looking at another mild day from the Coast to the interior with widespread max temps in the 60s F and a few pockets of lower 70s F also possible in the interior valleys. Given the cooler air mass above 1500ft, will see some of the highest peaks only get up into the 50s and low 60s F.

persist for the Bay Area and Central Coast with another batch of stronger late night winds. The SFO to WMC and SFO to ACV gradient has been increasing into the night causing these winds to build at a fair pace. This has allowed winds to gust above 60 mph at Mt St Helena and 50 mph at Mt Umunhum, but the mid to lower elevations have mostly stayed between 25 to 35 mph. These winds are set to last through the night and into Sunday morning, but look to ease into the afternoon.

Offshore flow continues for Sunday afternoon, keeping the skies mostly clear and allowing highs to peak in the 60s yet again. Sunday night offers some changes as a low pressure begins to move parallel to the coast. Models, ensemble members, and the national blend have been trending to have this low stay far enough off shore that it won't offer rain chances. Only a few ensemble members hinting as slight chances for light rain along the Big Sur Coast, but official forecast has been adjusted to agree with the majority of outputs; keeping things dry. The low will be close enough to provide more southerly winds. This will cause slightly cooler conditions along south-facing coasts for Monday afternoon, but the more interior areas will be unaffected.

Dry and mild conditions look to last through the work week. Daily highs will stay around 60 degrees along the coast with interior locations building into the mid to upper 60s. Overnight lows will stay in the 40s for most, but some of the interior valleys could fall into the mid 30s creating the potential for patchy frost.

The end of the work week presents some good potential for rain to return to the forecast. A building trough looks to bring a line of showers into the Bay Area Friday night, with fair agreements between deterministic models and their ensemble members on these chances. The official forecast has been tweaked to follow the timing of the National Blend, which offers some of the earlier chances, but allows the rainfall to linger into Saturday, which is closer to some of the ECMWF (European Centre for Medium-Range Weather Forecasts) ensemble members. Behind these chances, the longer term models are calling for a wetter pattern going into the second week of March as a trough deepens in the Eastern Pacific.
