158 PM PDT Tue Jun 22 2021 .Synopsis for the Central California Coast and Bays Including the Monterey Bay...Greater Farallones...and Cordell Bank National Marine Sanctuaries... Light to moderate southerly winds will continue over most of the coastal waters through Wednesday thanks to a low pressure system off the coast of California. This will also will bring more easterly winds across the northern waters. Winds will gradually shift back out of the northwest into Thursday with speeds remaining generally light to moderate. Mixed seas will persist with a short period northwest swell and a weaker longer period southerly swell. An additional northwest swell will arrive towards the end of the week.

Synopsis
Enhanced marine air influence coupled with an approaching upper level low continues to keep our region cool with near to below normal daytime highs. Marine stratus along the coast could bring a slight chance for drizzle again overnight into Wednesday morning with sunny to partly sunny skies tomorrow afternoon. A chance for another warming trend is possible for the upcoming weekend.

as of 03:00pm PDT Tuesday...A fairly solid deck of marine stratus from this morning has scattered out pretty well this afternoon, not just for inland areas, but also over the coastal waters making way for sunny to partly sunny skies across our region. The upper level low offshore is now centered near 36 N 125 W, about 165 miles west-northwest of Santa Cruz. Earlier this morning, the Fort Ord Profiler indicated a very deep marine layer up to 4000 ft, however, latest observations show that it's back down to around 3000 ft. Regardless, that's still a deep enough marine layer to allow for cooler, moist marine air to infiltrate well inland into much of our forecast area. Current temperatures are similar to yesterday at this time, within a few degrees so we're on track to see another afternoon of daytime highs in the mid 60s near the coast to mid 80s far inland. Marine stratus should redevelop overnight into Wednesday morning which will bring another round of potential coastal drizzle.

The upper level low will linger offshore tonight and gradually nudge inland on Wednesday and Thursday continuing our cool trend in temperatures. By Friday, an anomalously strong high will build over the Pacific Northwest and cause the low over Central CA to weaken. As it weakens, our daytime highs will start to work their way up the thermometer as we enter another warming trend. The high over the Pacific NW looks to potentially merge with high pressure to our south which will bring another heat event to our CWA. As stated in prior discussions, model uncertainty remains and the spread of potential high temperatures is rather large (by 10-20 degrees). We are confident that it'll be a hot weekend for inland areas with many locations getting into the 90s. What we are not as confident about is how extreme the heat could get for our typically hot spots (North Bay hills, East Bay valley & hills, the mountains of San Benito County and interior Monterey County). So while it is possible that some locations in our typical hot spots could get into triple digit heat, we're not sure how widespread the 100s will be or how high the peak max temps could get (low 100s vs up to 110 degrees). Regardless, we want folks to be prepared for heat in the interior regions of our forecast area, especially since we'll be having quite the cooler spell beforehand. Stay hydrated this weekend and avoid outdoor activities during the heat of the day to prevent heat related illnesses.
