Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
radar currently shows a few isolated showers over the waters. Slight chances of light rain and drizzle will persist through the weekend over the waters. Otherwise, gentle to moderate northerly winds continue through the afternoon today but begin to turn more southerly starting Sunday. These light southerly winds are expected to continue through the middle part of next week, but then turn to become more northwesterly beyond then.

New UPDATE

SYNOPSIS
Issued at 145 PM PDT Sat Jul 13 2024

Heat Advisory is in effect mainly inland portions of the Bay Area and north Central Coast until 9 pm this evening. It's still hot inland, however relative cooling is taking place helping to ease things a bit due to cloud cover along with a few isolated passing showers through the afternoon. High temperatures will continue to ease back to normal mid July highs in the mid 80s to 90s far inland early to mid next week. Closer to the coast and nearby coastal valleys a maritime influence will result in cooler daytime temperatures.

UPDATE
Issued at 647 PM PDT Sat Jul 13 2024

The Heat Advisory will expire 9PM tonight as the weak low pressure system will influence some cooler temperatures tonight. Temperatures are already showing a 5-10 degree drop compared to 24 hours ago. We are still monitoring the instability and mid-level moisture moving up from southern California, which has brought a slight chance for dry lightning over our area through Sunday. With the dry fuels, any lightning can raise fire weather concerns. So far no changes to the forecast at the moment and although there has not been any lightning so far, we will continue to monitor our radar for any convection.

SHORT TERM
(This evening through Sunday)
Issued at 155 PM PDT Sat Jul 13 2024

We continue to closely monitor satellite, radar and observations for incoming mid level moisture and instability from southern California. So far we're only seeing a few passing showers and since high resolution model output shows plenty of convective inhibition the expectation is this will continue to greatly limit any potential for thunderstorm development through afternoon and evening. There's forecast steepening of the 700-500 mb temperature lapse rates and weak mid level convective potential out ahead and northeast of the 500 mb low, currently 275 miles west of Point Conception, arriving late tonight and Sunday morning however just above this the 500-300 mb layer is stable. From approx the 700 mb level (~ 10,000 feet) downward through the 925 mb level (~ 2,500 feet) thermal ridging, stability remains in place tonight and Sunday morning.

Warm to hot far inland again this afternoon, however cloud cover will help reduce incoming solar input a little bit helping reduce highs a little compared to Friday afternoon. Cooler temperatures prevail along the coast and in the nearby coastal valleys due to increasing maritime influence, including coastal stratus and fog.

LONG TERM
(Sunday night through next Friday)
Issued at 155 PM PDT Sat Jul 13 2024

Summer continental surface heating continues to correspond to strong 500 mb heights with a nearly stationary high pressure system over the west with the center near the Four Corners. A stable north hemispheric pattern shows signs of strengthening and becoming unsteady again with five long wave troughs developing by late next week. One long wave trough is forecast to slowly progress eastward to along western North America while a long wave ridge primarily strengthens over central Canada with an extension, possibly the southern extension retrogressing toward the southwestern states. The GEFS/EPS ensemble 850 mb mean temperature forecasts for our forecast area climb back to 26 Celsius next weekend, not quite as warm as of recent, but bears watching.

AVIATION
(00Z TAFS)
Issued at 503 PM PDT Sat Jul 13 2024

VFR prevails through the mid evening, though stratus will begin to fill into are terminals as the sun begins to set. Winds will ease into the night to become light for most terminals. Stratus is likely to bring IFR CIGs initially, eventually becoming LIFR in the early morning of Sunday. There does remain some uncertainty as to whether CIGs will lower to LIFR, as troughing just off of the coast could lend just enough influence to help keep CIGs elevated. Therefore, confidence is low-moderate on LIFR conditions developing. Aside from this, stratus is expected to clear from terminals in the late morning Sunday, leading to VFR conditions once more.

Vicinity of SFO...VFR lasts through the late night tonight, but stratus is expected to begin to filter over the terminal beyond sunset bringing low clouds. These low clouds are expected to eventually form IFR CIGs in the early morning of Sunday. IFR lasts through the late morning, then clearing to VFR. High clouds are likely to be present through the remainder of the TAF period as upper level moisture enters the region.

SFO Bridge Approach...Stratus will fill into the Bay in the early morning of Sunday bringing low clouds.

Monterey Bay Terminals...Stratus will continue to fill in this evening to bring initially IFR CIGs . Towards midnight, CIGs are expected to lower to become LIFR and visibilities may reduce slightly as fog and mist develops. LIFR conditions then last through the late morning of Sunday. Clearing to VFR expected in the late morning, with winds slowly increasing to become breezy and onshore in the afternoon. High clouds will be present.

MARINE
(Tonight through next Friday)
Issued at 503 PM PDT Sat Jul 13 2024

Slight chances of isolated light rains showers exist this weekend over the waters, though any precipitation that does fall is most likely to be drizzle. Otherwise, gentle to moderate northerly winds continue through the afternoon today but begin to turn more southerly starting Sunday. These light southerly winds are expected to continue through the middle part of next week, but then turn to become more northwesterly beyond then.

FIRE WEATHER
Issued at 1030 AM PDT Sat Jul 13 2024

Mid level cloud cover/moisture moving up from southern California is resulting in widely scattered showers, a few spots have reported a trace (and possibly light measurable precipitation) reaching the ground. Forecast soundings show widespread convective inhibition over our forecast area today i.e. stability greatly helping to preclude thunderstorm development. Per satellite and high resolution model output, mid level cloud cover over our forecast area will help reduce incoming solar input today. 12z statistical guidance shows slightly cooler temperature trends including inland areas today. The marine layer temperature inversion at the mountain tops is still quite warm, however 24 hour trends show cooler temperatures almost everywhere this morning, also resulting in positive humidity trends.

A well established marine layer with coastal stratus has recently shown signs of deepening per Bodega Bay and Fort Ord profiler data.
The southerly and onshore pressure gradients and winds prevail which will help usher higher humidity to the inland valleys, hills and eventually mountain tops.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Heat Advisory until 9 PM PDT this evening for CAZ504-510-513>515- 517-518.

PZ...None.
