PZZ500 838 Am Pdt Thu May 23 2024
Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
building surface high pressure over the eastern pacific ocean will allow for strong northwesterly winds to prevail for one more day today, with gale force gusts across the outer coastal waters. Expect hazardous conditions and steeper wind waves as a result. Northwesterly winds diminish and significant wave heights abate heading into the weekend as surface high pressure over the eastern pacific ocean weakens and retrogrades to the west and a troughing pattern evolves.

New SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1225 PM PDT Wed May 22 2024

Summer-like pattern to persist through Thursday. Temperatures are forecast to dip below seasonal averages this weekend as an upper level trough impacts the region. Temperatures begin to warm Sunday through the next week.

SHORT TERM
(This evening through Friday)
Issued at 1244 PM PDT Thu May 23 2024

The sun is shining over our area, as satellite shows clear skies over our area. Soundings show that there has been some drier air that moved over our region and helped diminish the marine clouds.
Some patches of clouds are expected to return tonight near the Bay Area, with moments of lower clouds near Monterey Bay and Salinas similar to this morning. Minimum temperatures tonight will drop overall in the 40s with isolated areas of low 50s. Maximum temperatures will drop significantly compared to today (between 5-8 degree drop). Inland areas will see within the 60s with higher elevations seeing up to low to mid 70s. Coastal areas will see temperatures in the 50s. Minimum relative humidity will also increase on Friday, indicating some moisture will be pulled in from the onshore breeze.

LONG TERM
(Friday night through next Wednesday)
Issued at 1244 PM PDT Thu May 23 2024

The low pressure system centered over Washington and Oregon, will continue to dip south a bit, which will enhance and influence some of the cooling trend over our area. Ensemble models still indicate that temperatures will drop to cooler than normal high temperatures with majority of our region seeing high 50s to low to mid 60s on Saturday. Temperatures overnight will remain relatively consistent through the weekend with minimum temperatures in the 40s to low 50s. Tuesday night may start to see a slight warm up in overnight temperatures with minimums in the 50s across most of the area. Cluster models also have been in somewhat of an agreement of precipitation Friday going into Saturday as some onshore flow pushes some of the marine moisture near the coast. Chances for precipitation will be 5-10% for less than a tenth of a inch along the coast, which will likely be in the form of drizzle and will cause little to no impacts.

As the trough moves off to the east, the ECMWF and GFS show agreement of a broad, weak ridge beginning to build on Sunday into Monday. This will bring some warmer temperatures for the week, especially in the interior regions, with max temperatures in the high 70s and low 80s. With this weak upper level pattern change, models do not show a strong offshore signal, which will allow for a onshore breezy to continue. This will cause coastal regions to only warm up a bit, with temperatures in the high 50s to mid 60s.

AVIATION
(18Z TAFS)
Issued at 1024 AM PDT Thu May 23 2024

Currently VFR at all terminals with sparse stratus coverage in the Monterey Bay and along the Big Sur Coast. Moderate confidence of VFR through the TAF period at all terminals with the exception of the Monterey Bay terminals of MRY and SNS. Low clouds in the range of FL015-FL035 could impact the terminals of LVK, OAK, SFO, and SJC overnight; however, confidence was not high enough at this time to include as a definitive ceiling.

Vicinity of SFO...Currently VFR with breezy northwesterly flow. VFR through the TAF period. Winds will transition to become westerly with gusts up to 30 knots to be expected this afternoon and evening.
Low confidence in the development of an MVFR ceiling, but low clouds in the range of FL030-FL050 will be present by the early morning hours and linger through the end of the TAF period.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with northwesterly flow at both terminals. Moderate confidence that MVFR stratus will return to both terminals overnight. Winds will remain breezy out of the west through the TAF period.

MARINE
(Today through Tuesday)
Issued at 1024 AM PDT Thu May 23 2024

Building surface high pressure over the Eastern Pacific Ocean will allow for strong northwesterly winds to prevail for one more day today, with gale force gusts across the outer coastal waters.
Expect hazardous conditions and steeper wind waves as a result.
Northwesterly winds diminish and significant wave heights abate heading into the weekend as surface high pressure over the Eastern Pacific Ocean weakens and retrogrades to the west and a troughing pattern evolves.
