Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
breezy and gusty winds last through Friday, with gale force gusts of 40 to 45 knots possible in the outer waters through much of the week. The strong winds will result in hazardous seas and steep wind waves with significant wave heights reaching 10 to 14 feet in the outer waters. Conditions will gradually improve over the weekend and into next week as winds begin to ease. Chances of rain begin early Saturday as a trough descends over the region.

New AVIATION
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.
UPDATE
Issued at 856 PM PDT Tue Apr 30 2024
Relatively quiet weather as we transition from April into May.
HRRR continues to indicate minimal cloud cover overnight which will allow overnight temperatures to cool into the mid to low 40's. Tomorrow's temperature forecast looks to remain on track with inland highs in the low to mid 70's and coastal highs in the upper 50's to low 60's. Gusty northwest winds gradually becoming more northerly will continue through the end of the work week.
No updates needed to the forecast. This concludes April 2024.
SHORT TERM
(This evening through Wednesday)
Issued at 106 PM PDT Tue Apr 30 2024
Overnight temperatures are forecast to cool into the 40's across much of the region with less cloud cover. However, areas around the Monterey Bay have the potential to see low clouds develop once again. Once any low clouds that do develop dissipate, temperatures will begin to warm and are likely to reach into the 60's near the coast (70's in places such as Santa Cruz) with mid-to-upper 70's inland.
LONG TERM
(Wednesday night 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 1022 PM PDT Tue Apr 30 2024
Generally VFR through the TAF period with patchy stratus in the higher elevations. Westerly flow will diminish through the night, but northerly winds aloft remain strong, causing LLWS across the region through Wednesday morning. Northerly winds build through Wednesday, generally gusting through 20-25 knots.
Vicinity of SFO... VFR through the TAF period. West winds diminishing through the night with northerly winds aloft causing LLWS early Wednesday morning. Northwest winds build through Wednesday gusting to 20-25 knots, before diminishing through the evening.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... VFR through the TAF period. Directional LLWS through Wednesday morning as valley drainage flow at the surface meets northerly flow aloft. Northwesterly flow develops on Wednesday with gusts up to 20-25 knots, diminishing again in the evening with directional LLWS resuming at MRY.
