Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Gusty northwest winds will persist into Monday morning with hazardous seas conditions for much of the waters, particularly for smaller vessels. Winds will diminish Monday afternoon and evening. Light to locally moderate winds will then persist into mid week before increasing over the outer water by late week. Mixed seas continue with a short period northwest swell and a weak longer period southerly swell. An additional longer period northwest swell will arrive around mid week.

Area Forecast Discussion National Weather Service San Francisco Bay Area 429 PM PDT Sun Sep 19 2021
SYNOPSIS. Mostly sunny and mild this afternoon. Red Flag Warnings go into effect at 11 pm for the North and East Bay hills as well as the East Bay interior valleys through 8 pm Monday for drying offshore winds. Otherwise sunny and warmer Monday and Tuesday regionwide under fall offshore wind pattern. Slight cooling trend by Wednesday but continued dry and seasonable through the work week.
DISCUSSION. as of 2:03 PM PDT Sunday . Skies have cleared out behind last nights frontal passage with just some lingering clouds over the ocean and a few instability clouds over the hills this afternoon with mild temps warming into the upper 70s and lower 80s inland. All focus will shift to developing offshore winds and associated Red Flag Warning as well as a noted warming and drying trend for Monday and Tuesday.
Todays forecast focus has been on the Red Flag Warning that covers the North/East Bay hills and East Bay valleys from 11 pm tonight through 8 pm Monday. As expected any rainfall of note was confined to northwest Sonoma county down to coastal Marin. Interior North Bay and the heart of the Bay Area generally saw trace amounts or less than a tenth which is not considered a wetting rain or enough to have an appreciable impact on the fine fuels let alone the heavier drought impacted fuels. So the areas of most concern will be the Napa hills across the North Bay as well as the East Bay hills/valleys where stronger winds, low humidity values and dry fuels are most likely to line up.
For tonight northerly winds will develop over the Napa hills before midnight and then spread over the rest of the Bay Area hills overnight into Monday morning. Initially most of the strong winds will be confined to the higher ridges above 2000 feet before slowly mixing down closer to the 1000 foot elevation. We can expect to see some gusts to around 50 mph for Mt Saint Helena and Diablo but more significant rainfall was observed around those higher peaks last night. The initial burst of winds will arrive with humidity readings quite moist, thus the period of strongest winds will not line up with the lowest humidity but rather the initial energy of the winds will be spent drying the fine fuels out. Without getting too esoteric its also worth noting the 10 hour fuel stick values are remaining fairly high, even for those locations that didn't see rainfall so fuel conditions are not too extreme going into the event which is supported by the latest ERC fuel chart readings as well. Nonetheless the synoptic weather pattern features a fairly typical mid-September offshore wind event. From sunrise through about 10 am winds should be peaking in strength regionwide and riding on-top of the nighttime inversion layer right around 1000 to 1500 feet in elevation. As the morning inversion breaks some of those winds will mix down to the lower elevations of the North/East Bay as well as the coastline. As this occurs we should see rapid spike in temperatures before noon on Monday as readings quickly approach 80 degrees, even near the coast and bays. Persistent but fairly light offshore flow to continue through Monday afternoon but the main impact will become hotter temps regionwide with widespread upper 80s to mid 90s as humidity values lower into the teens.
Offshore flow to continue Monday night but as the sun goes down we dont expect any strong wind speeds. Thus for now and in coordination with neighboring offices will plan to let the Red Flag expire at 8 pm Monday evening. That being said we expect little or no humidity recovery Monday night into Tuesday morning, especially in the hills with readings staying from 18-30% overnight keeping conditions near critical.
The offshore flow should ease by Tuesday morning but the stage will be set for another hot day with widespread readings in the upper 80s and 90s. Were at the time of year when things become more isothermal and the hottest temps can actually be closer to the coast under offshore/downslope flow. No expectation of any heat products as the dry airmass will allow good radiational cooling under the longer Sept nights.
Will be watching a midweek shortwave that will turn the wind pattern back to onshore by Weds morning and induce a modest cooling trend. This feature will get rid of the inland 90s but still expect comfortable temps in the 70s and 80s for Weds.
Models then take the midweek shortwave and drop it towards the Central Valley before potentially it turns into a weak cut-off low by late in the week. Nearly all the models are now indicating this potential with the likely result of little appreciable impact of note for the Bay Area though some solutions indicate an outside chance of some showers for the Central Coast though that remains doubtful. The North Bay and greater Bay Area will likely be on the dry northeast side of the upper low with fair and nice wx.
Longer range solutions suggest as that feature finally kicks out towards Nevada dry high pressure will build later next weekend with continued dry and seasonable weather.
AVIATION. as of 04:29 PM PDT Sunday . For the 00z TAFs. Satellite imagery shows stratus remains along the coast from Sonoma County down through the Monterey Bay as well as some scattered cumulus and a line of passing high clouds. VFR conditions are expected to prevail as dry offshore flow sets up tonight and persists through the forecast period. As northerly winds strengthen overnight, there is a possibility of LLWS (mainly in the North and East Bay) late tonight into early tomorrow morning. Breezy northwest winds this afternoon in the wake of a cold front with most sites around 10 to 20 kt into this evening before surface winds diminish tonight. Occasional higher gusts overnight may mix down to the surface from the offshore flow aloft, but no widespread consistent stronger winds are anticipated.
The latest HRRR smoke model is showing an increase in total smoke beginning just at the end of this taf package from south to north. Expect reduced slant range visibility starting late tomorrow afternoon.
Vicinity of KSFO . VFR. Breezy W/NW winds this afternoon at 15 to 25 kt diminishing this evening. Increasing offshore winds aloft overnight may lead to some LLWS on and off into early Monday morning.
KSFO Bridge Approach . Similar to KSFO.
Monterey Bay . VFR prevailing, though satellite does show some stratus moving into the Monterey Bay. There is the chance of SCT to BKN cigs developing over the terminals early this evening. Should this occur, expecting clearing to occur by early Monday morning. Breezy onshore winds this afternoon around 10-15 kt diminishing overnight. As mentioned above, HRRR smoke model shows increasing smoke beginning late tomorrow afternoon.
MARINE. as of 04:21 PM PDT Sunday . Northwest winds with stronger gusts continue to strengthen Sunday and into Monday. Hazardous seas conditions will develop over much of the waters, particularly for smaller vessels. Seas remain mixed with a short period northwest swell and a weak longer period southerly swell. An additional longer period northwest swell will arrive around mid week.
MTR WATCHES/WARNINGS/ADVISORIES. Tngt. Red Flag Warning . CAZ507-510-511 SCA . Mry Bay until 9 PM SCA . Pigeon Pt to Pt Pinos 0-10 nm until 9 PM SCA . Pt Arena to Pigeon Pt 10-60 nm from 9 PM SCA . Pt Pinos to Pt Piedras Blancas 0-10 nm SCA . Pt Arena to Pt Reyes 0-10 nm until 3 AM
