New SYNOPSIS, SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1237 PM PDT Tue May 21 2024

Summer-like pattern to persist through Thursday. Temperatures are forecast to dip below seasonal averages by the upcoming weekend as an upper level trough impacts the region.

SHORT TERM
(This evening through Wednesday)
Issued at 1237 PM PDT Tue May 21 2024

The broad tilted upper level troughing pattern over California has brought some weak offshore winds over interior areas, causing some warmer temperatures and drier conditions. The offshore flow will help inhibit some of the marine layer from reaching inland tonight into Wednesday morning allowing for another blue sky morning for interior regions. On the other hand, the weak onshore flow along the coast will bring some low clouds along the coastal areas, especially near Monterey Bay and Salinas Valley tonight. Models show interior regions will be on the drier side this evening with minimum relative humidity values between 14-30%.

Overnight temperatures are relatively the same as last night with minimums in the mid to upper 40's to low to mid 50's. Some isolated areas will see a slight increase 2-3 degrees higher. Temperatures will start to trend cooler on Wednesday, but still will be relatively warmer than usual with inland max temperatures in the low 80s to high 70s, as coastal areas will see temperatures in the upper 50s to 60s. The onshore flow along the coast will increase on Wednesday, which will help increase some relative humidity values between 20-55%.

LONG TERM
(Wednesday night through next Monday)
Issued at 1237 PM PDT Tue May 21 2024

The low pressure system that sits in the northwest, will drop south a bit on Thursday and will move across the Pacific northwest over the weekend, which will bring stronger onshore flow and cooler temperatures. Thursday will start to see max temperatures in the mid 70s inland and upper 50s to 60s along the coast. Friday through the weekend, max temperatures are expected to drop between 5 to 7 degrees below average over the weekend with mid 50s to low 60s coastline and upper 60s to low 70s inland. With the stronger onshore flow, expect the gloomy mornings pattern to continue along the coast, with slow clearing in the mornings. Ensemble models show no impactful precipitation associated with this trough as it moves through our area this weekend, but if precipitation does occur this weekend, expect the best chance to occur near the coast. On Sunday into Monday, a weak ridging will develop over our area bringing back some slightly warmer temperatures.

AVIATION
(18Z TAFS)
Issued at 1020 AM PDT Tue May 21 2024

Currently VFR at all terminals with stratus hugging the coastline from the San Francisco Peninsula down to Point Conception. Moderate- high confidence of VFR through the TAF period at all terminals with the exception of the Monterey Bay terminals of MRY and SNS.

Vicinity of SFO...Currently VFR with offshore flow. VFR through the TAF period. Winds will transition to become breezy out of the west by this afternoon with gusts up to 25 knots to be expected.
Confidence is moderate that the terminal will evade a ceiling; however, there will likely be low clouds in the FL010-FL030 range between 10Z and 16Z. Winds will become breezy out of the west again tomorrow afternoon with gusts up to 25 knots to be expected.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with westerly flow at MRY and VFR with northerly flow at SNS. Moderate-high confidence that MVFR stratus will return to both terminals overnight, with lower confidence on if ceilings will dip into IFR territory. Winds will remain breezy through the TAF period and out of the west/southwest for MRY and out of the west/northwest for SNS.

MARINE
(Today through Sunday)
Issued at 1020 AM PDT Tue May 21 2024

Building surface high pressure over the Eastern Pacific Ocean will continue to allow for strong northwesterly winds to prevail through Thursday, with gale force gusts across the outer coastal waters. Expect hazardous conditions and steeper wind waves during the week. Winds diminish heading into the weekend as surface high pressure over the Eastern Pacific Ocean weakens and retrogrades to the west.

MTR WATCHES/WARNINGS/ADVISORIES
