Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Scattered showers are over the southern waters and moving northward. Lightning activity has decreased on radar, but there remains a slight chance for an isolated Thunderstorm through Friday afternoon, with the potential for locally gusty winds and rough seas near these storm cells. Moderate northwest winds are expected over the northern waters through the weekend. Prevailing seas remain mixed with a short period northwest swell and a longer period southerly swell.

Area Forecast Discussion National Weather Service San Francisco Bay Area 1034 PM PDT Thu Aug 13 2020
SYNOPSIS. Hot temperatures Friday into the weekend with inland Excessive Heat Warnings and Bayside Heat Advisories in effect. Continued hot through early next week.
DISCUSSION. as of 10:07 pm Thursday . Interesting weather day for the Central Coast with KMUX radar lit up much of the day. However little or no lightning over land. Latest scans shows most showers now offshore, west of Big Sur. Latest model simulations suggest that any convection will reorganize offshore, closer to the main upper low. IR satellite shows slug of mid and high level clouds now over the Bay Area. These clouds kept places like Parkfield in southern Monterey county with a relatively cool high of 81 (its usually the hottest spot in the cwa) while the Bay Area got a taste of heat with a record tying high of 95 at Redwood City while Concord and Livermore both exceeded 100 degrees.
Heat Warnings go into effect Friday for inland areas and last through the weekend and into early next week per coordination with neighboring offices. Strong ridge over the Desert Southwest will bring significant heat to much of the state while the remnant moisture (clouds) over the area has brought some humidity rises and associated increased heat risk. Heat Advisory is in place around the Bay including Santa Cruz county on Friday. No headlines for the City or coast but there will be little seabreeze with warm temps all the way to the coast given the lack of a marine inversion layer. Will be monitoring day to day heat advisories this weekend for bayside locations while interior hot weather looks to be a slam dunk thus the continuous excessive heat warning.
Will peruse the 00z data shortly but no big weather changes forecast for awhile. Be ready for a prolonged heat event with little night time relief. Fires across the state are showing explosive growth, even in the absence of wind so please use caution with any fire sources given the dry and receptive fuels.
PREV DISCUSSION. as of 1:52 PM PDT Thursday . Storms fired up this morning across our southern waters and slowly moved to the northeast, becoming more enhanced by the slug of moisture from the remnants of tropical storm Elida that has been moving up along the California coast. The 12Z NAM-12km run from today captured some of the morning elevated convection off the coasts of Santa Barbara and SLO Counties but failed to capture the larger cluster of elevated convection that developed over the southern waters of our CWA this morning as well. This larger cluster weakened significantly by 19Z and its outflow has ignited some new storms due west of it while the elevated convection closer to SLO county came ashore late this morning. Similar elevated convection is expected to move into far southern Monterey County this afternoon as well. High cirrus associated with both clusters has engulfed most of the southern CWA and made it into parts of the Bay Area. Our 18Z sounding was able to capture some of the weak instability at the mid-levels along with some of the 300-250hPa cirrus.
Depending on how quickly the moisture moves into the central and northern CWA today and through early Friday afternoon, could see more storms training off the coast through the period and potentially making their way ashore, with the highest confidence still being for convection to trail over southern Monterey County. PWATs remain over >1 inch across the CWA as the tropical moisture treks northward. Air mass near the surface is still dry. Thankfully the majority of the lightning that has been detected since dawn has been offshore. Moreover, as more moisture moves overhead we can expect for any storms that move ashore later tonight and into tomorrow morning to be wet thunderstorms. In the meantime, continue to monitor lightning as the elevated convection continue coming ashore. Expecting the majority of this tropical moisture to depart our CWA by Saturday.
Outside of the convection, marine layer compression has continued through the day as the weak offshore low is cast aside by the expanding upper-level ridge over the Southwestern US. The Nam12km runs continue to keep us slightly warmer than the GFS20km runs, but regardless we are expecting warm coastal conditions along the coast and hot conditions across the interior. In the coming days, 590dm heights are progged to move into our area. Both the 12Z GFS- 20km and NAM-12km runs from today have increased their confidence for 850hPa temps over 25 deg C across the CWA by Friday afternoon as the ridge builds to a 596dm. Unlike what has happened for the most part this summer, the offshore mid-level low will not be the dominating synoptic pattern for the weekend. Coastal locations will likely make it into the low 80s through the weekend while interior locations will easily climb the mid-90s F, with up to 108 F in some of our warmest locations like Lake Berryesa and Pinnacles. Also not expecting much in the way of temperature recoveries this weekend, with overnight mins staying rather mild all across the CWA. As the ridge builds through the weekend and into the first half of next week, the 00Z GFS ensembles move the center of the ridge closer to the Utah/Nevada border, while the 00Z ECMWF run from today takes a more aggressive approach and builds it to 601dm over central Nevada and moves 569dm-598dm heights into our CWA Monday evening. Will keep a close eye on the latest model runs in order to assess how long the heat wave will persist across the CWA, but at the moment it's looking like aside from some minor cooling during the middle of next week, this will be a prolonged event.
In the meantime, excessive heat warning is now in effect across the entire from Friday into Wednesday while a heat advisory has been issued only for targeted regions of the North Bay valleys, SF shoreline, and the Santa Cruz Mountains.
AVIATION. as of 10:34 PM PDT Thursday . for 06z TAFs. It's VFR except for a few patches of LIFR in patchy coastal stratus vicinity KHAF. Mid and high clouds continue to move northward to the Bay Area, most of the showers have remained offshore or south of the terminals.
Vicinity of KSFO . VFR. Mid to high clouds overnight into Friday.
SFO Bridge Approach . Similar to KSFO.
Monterey Bay Terminals . VFR. Mid to high clouds overnight and Friday.
MARINE. as of 9:54 PM PDT Thursday . Remnant tropical moisture will bring a chance of thunderstorms to the southern waters into this evening. Locally gusty winds, rough seas, and frequent lightning with some of these cells will be possible. Otherwise, generally light to moderate northwest winds across the waters through the weekend aside from locally breezy winds over the northern outer waters into this evening. Mixed seas will persist through the period with a short period northwest swell and two longer period southerly swells.
