Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
a strong northerly pressure gradient will continue producing hazardous conditions due to gale force wind gusts through mid- week. Gale force wind gusts of 40 to 45 knots will be possible over the outer waters and portions of the immediate coast near point reyes and point sur. The strong winds will result in fresh steep wind waves with heights reaching 10 to 12 feet. Conditions will gradually improve late in the week into next week.

New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 133 AM PDT Tue Apr 30 2024
High pressure brings quiet weather and slowly warming temperatures this week. Breezy onshore winds will keep temperatures along the coast cooler however. Cooler and more unsettled conditions return this weekend into next week with light rain chances in the forecast.
SHORT TERM
(Today and tonight)
Issued at 203 AM PDT Tue Apr 30 2024
Dry conditions prevailing with high pressure from the offshore waters to far northern California and the Pacific Northwest.
Gusty northwest winds continue over the coastal waters. Forecast highs today 60s near the coast and bays to the 70s inland.
LONG TERM
(Wednesday through Monday)
Issued at 203 AM PDT Tue Apr 30 2024
Dry conditions prevailing through mid-week. A slowly retrograding long wave trough along the West Coast varies in strength late week and early next week. There is a large difference between recent GFS (wet) and ECMWF (not nearly as wet as the GFS) in calculating the trajectory/progression of a low pressure system moving through the long wave trough, now well within 120 hours (5 days) forecast. QPF differences are showing up in the GEFS and EPS as well, though recent EPS have increased a little. As of current, it remains a low confidence forecast from a global model forecast perspective. Given the model forecast trajectory of the low pressure system is from near the Bering Sea/Aleutians southeastward across the Pacific (and surface high pressure over the Pacific retrogrades)
where below normal sea surface temperatures exist including a negative phase Pacific Decadal Oscillation (PDO) i.e. the potential forward slowing due to local surface heating is reduced therefore the quicker arriving QPF in the GFS solution may not be that far off if development much closer to our forecast area verifies. The northern hemispheric pattern remains active with the current number of long wave troughs reflecting a winter-like circulation.
Stay tuned to latest forecast updates, as currently advertised the official forecast shows potential for showery, cool weather this weekend. Planning travel to the mountains? This pattern has potential for snow accumulations, it's a good idea to monitor the latest forecasts. Per 30 year climatology we are of course past peak cool season rainfall, however it can still rain in May in the Bay Area and north Central Coast. Recalling a Lead Forecaster here years ago mentioned it's always a good idea to carry chains in case needed (for Sierra Nevada travel) through Memorial Day.
July climatologically is our driest time of year since by then the jet stream has reliably weakened and returned northward and high pressure often sets up.
AVIATION
(06Z TAFS)
Issued at 1012 PM PDT Mon Apr 29 2024
Generally VFR through the TAF period with patchy stratus in the higher elevations. Light to moderate onshore winds tonight will build through Tuesday, but not expecting gusts as intense as those seen earlier today. Tuesday evening through Wednesday morning should largely remain VFR throughout the region.
Vicinity of SFO... VFR through the TAF period. Breezy west-northwest winds will gradually diminish overnight before resuming on Tuesday.
As of now, winds expected to gust up to 30 knots on Tuesday afternoon and evening.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... Low confidence (20-30% probability) that a patch of MVFR stratus forming over the northern Santa Lucias impacts MRY Tuesday morning, and again late Tuesday evening into Wednesday morning. Otherwise, generally VFR through the region with breezy onshore flow developing Tuesday afternoon and evening.
MARINE
(Tonight through next Sunday)
Issued at 1012 PM PDT Mon Apr 29 2024

The strong winds will result in fresh steep wind waves with heights reaching 10 to 12 feet. Conditions will gradually improve late in the week into next week.
