The marine layer continues to stay strong with the day starting off with nearly widespread lower clouds. A good amount of drizzle has been reported across the North Bay, but chances have reduced into the late morning. Higher clouds are also moving into the area, which could limit the erosion of the lower clouds, leading to cooler conditions. Expect the coast to remain cool under cloudy skies with highs in the 50s. Then the areas slightly inland will hover around the mid to lower 60s, and the far interior will be in the 70s with possibly one or two spots breaking 80 degrees in southern Monterey Co.
Overnight will begin the next pattern change as a cold front begins to pass through the area a low pressure following close behind. This will cause most of the region to see the coolest high temperatures and cloudiest skies of the forecast. The rush of cooler air along the front will off good chances for drizzle across much of the Bay Area and Central Coast, with the best chances being along coastal peaks. While overall precip chances look good, the overall totals look to stay below just a few hundredths of an inch. Winds will be breezy and gusty across much of the CWA during this pattern change, with the higher elevations and favored gaps and passes seeing chances for gusts peaking around 45 mph. The forecast continues to show the front exiting the North Bay early enough in day( and northerly dry winds around the low) for some slight and isolated warming compared to previous days, while the rest of the region remains cool.

Cloud cover erodes Tuesday evening as northerly winds build across the region in the post-fontal environment and the parent low pressure pushes east. Winds decrease into the night, but remain northerly. The drier airmass arriving to the region will allow for widespread lows into the 40s for Wednesday Morning, making it the coolest morning of the forecast. Models hint at a weak marine layer reforming as winds reduce, but it looks to not be as moisture rich as the last few days and barely moves inland.
From there, the models are in fair agreement over another warming and drying trend as a modest offshore flow develops as the low travels to the east. High temperatures see a notable rebound for Wednesday as skies remain on the clearer side, with temperatures steadily warming into the weekend. However, the weekend itself has a wide range of potential pattern change across models and ensembles. While some keep the warming trend and offshore flow due to modest ridging, others hint at a more zonal (west to east) flow developing and pushing onshore flow at the surface. The current forecast leans on the continued warming trend model outputs, but that can change quite a bit as new model runs publish and higher resolution models come into range.

A cold front associated with a low pressure system to our north will move through the Bay Area and Central Coast overnight into tomorrow morning. This will bring a chance for drizzle to coastal sites with some high res models suggesting some potential for light rain along the coast tonight. Winds remain breezy overnight with gusts between 20-25 knots overnight. Winds are expected to strengthen in the wake of frontal passage with widespread northwest gusts between 25 to 35 knots Tuesday morning into the evening. CIGs are expected to lower overnight but will rise/dissipate after frontal passage occurs. For the Bay Area CIGs clear around 10-12Z while CIGs clear closer to 14/15Z for the Central Coast.
Vicinity of SFO, Gusts up to 30 knots are expected to continue into this evening before winds ease slightly overnight. MVFR CIGs are expected to filter in late this evening before dissipating around 10Z after cold frontal passage. Gusts strengthen again tomorrow with gusts in excess of 35 knots becoming likely after 18Z and continuing through late Tuesday.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, MVFR conditions have already reached MRY and SNS. CIGs are expected to continue through 14/15Z when cold frontal passage occurs and cloud cover is expected to dissipate. Winds remain breezy overnight and will strengthen further Tuesday morning into the evening. Northwest gusts between 25 to 30 knots are likely at MRY and SNS during the afternoon and evening hours.
