12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Light to moderate winds will prevail over most of the coastal waters through Tuesday. Locally stronger winds will occur south of point sur along the coast. Northerly winds will develop and increase over all the coastal waters Tuesday night into Wednesday. The increasing winds will result in steeper wind waves. Moderate northwest swell of 10 feet or more will bring hazardous conditions for small craft over most of the coastal waters. Another long period northwest swell will arrive later this week.

Area Forecast Discussion National Weather Service San Francisco Bay Area 428 PM PST Mon Jan 27 2020
SYNOPSIS. Dry conditions are likely to persist region-wide today with light rain possible over the North Bay late tonight into Tuesday. A warming trend is then expected from Wednesday through Saturday. While dry conditions will continue, a cooling trend will occur by late in the upcoming weekend.
DISCUSSION. as of 02:00 PM PST Monday . Temperatures across the region this afternoon are in the upper 50s to low 60s with not much additional warming anticipated. Overall expect temperatures to top out into the low to mid 60s for most locations. Satellite imagery shows low clouds lingering around the Bay Area with some scattered clouds south of San Jose. Synoptically, high pressure remains situated over the eastern Pacific while high clouds approach ahead of a weak upper low. This system is set to move into the Pacific Northwest tonight while an associated cold front moves through the Bay Area late tomorrow morning and into the afternoon. As a result, the North Bay may see some light precipitation late tonight and tomorrow morning with lingering showers possible into the afternoon. Precipitation chances lessen significantly south and east of San Francisco, although a stray shower or two is not out of the question. Accumulations still look fairly minimal with a few hundredths to around a tenth of an inch expected across the North Bay.
Once the system exits the region later tomorrow, an upper level ridge will build over the eastern Pacific and expand inland through late week. This will bring dry and warming conditions to the area for the rest of the week and into the weekend. Models show 850 mb temperatures increasing to around 15 deg C by Friday and Saturday. For comparison, the 00z OAK sounding had yesterday afternoon around 6 deg C at 850 mb. By Thursday, highs are forecast in the mid to upper 60s with low to mid 70s expected for Friday and Saturday. This translates to roughly 5 to 10 degrees above normal to end the week and start the weekend. Conditions will begin to cool on Sunday and further on Monday as an upper trough moves through the region, though dry weather will likely persist.
Looking out into the longer term, the CPC 6-10 day and 8-14 day outlooks show below normal precipitation for California. Additionally, the longer range GFS shows dry conditions across much of the region through early February. Ensemble QPF for both the GFS and the ECMWF show mainly dry conditions as well through at least the first week of February with only some occasional minor accumulations here and there. Overall, dry weather looks to persist across the region heading into next month.
AVIATION. as of 4:28 PM PST Monday . Ongoing difficult analysis and forecast primarily regarding ceilings due to a succession of a weak warm front to weak cool front today to a weak warm front to mainly weak cool front Tuesday within a 24 hr period per theta-e and temperature advection forecasts. Low clouds have been slow to clear today. Timing return of low clouds tonight is a very difficult forecast, outgoing night-time cooling of the boundary layer via radiative processes will be slower tonight due to incoming mid to high level clouds. Based off recent meso-model output Tuesday's cool front spreads light showers from north to south during the day.
Vicinity of KSFO . Recently went VFR at the terminal, VFR could hold longer through 02z advertised MVFR ceiling as long as drying continues to move in from the west coupled with lingering late day diurnal mixing. Will continue to coordinate with the CWSU on this through the evening.
SFO Bridge Approach . Low cloud ceiling has finally mixed out to scattered clouds, otherwise similar to KSFO.
Monterey Bay Terminals . VFR, west to northwest winds 5 to 10 knots early this evening becoming light and variable early to mid evening then light SE late evening. IFR-MVFR ceilings returning tonight and Tuesday morning, MVFR Tuesday.
MARINE. as of 3:27 PM PST Monday . Light to moderate winds will prevail over most of the coastal waters through Tuesday. Locally stronger winds will occur south of Point Sur along the coast. Northerly winds will develop and increase over all the coastal waters Tuesday night into Wednesday. The increasing winds will result in steeper wind waves. Moderate northwest swell of 10 feet or more will bring hazardous conditions for small craft over most of the coastal waters. Another long period northwest swell will arrive later this week.
