New AVIATION

SYNOPSIS
Issued at 1226 AM PDT Fri Apr 26 2024

Light rain showers are possible today as a weak cold front moves through the region. Breezy winds arrive later this afternoon into tonight behind the frontal passage. Increasing sunshine will kick off a warming trend Sat-Tue.

UPDATE
Issued at 902 AM PDT Fri Apr 26 2024

A different style and and set up to the region's cloud cover today, but still a cloudy and drizzly start. The breezier winds and change in pattern will allow for some inland clearing this afternoon, while the coast remains cloudy and drizzly.

SHORT TERM
(Today and tonight)
Issued at 1226 AM PDT Fri Apr 26 2024

An upper trough will progress from the Pacific Northwest through the Great Basin and and Desert Southwest through this evening. The upper feature will escort a weakening cold front through the Bay Area and Central Coast today with drizzle and/or light rain showers accompanying its passage through this afternoon. Overall precipitation amounts will be on the light side and generally under 0.05", although an isolated spot or two along the coastal terrain could receive up to 0.15". Breezy northwest winds will pick up rather quickly this afternoon and evening with lower elevation gusts mostly in the 20-35 mph range. Still looking a bit below Wind Advisory thresholds but it will be strong enough to blow around loose items and perhaps bring a few tree branches down. Temperatures will be seasonally cool with highs mostly in the lower to mid 60s.
However with breezy onshore winds the beaches likely won't get out of the upper 50s. Lows tonight will be a bit cooler following the frontal passage with temperatures mostly in the 40-45 degree range except near 50 along the immediate coast and within the urban areas.

LONG TERM
(Saturday through Thursday)
Issued at 426 AM PDT Fri Apr 26 2024

Forecast philosophy remains unchanged from yesterday afternoon. The previous discussion follows:

The new upper level pattern keeps mostly northwest onshore flow into the weekend. While the immediate coast will continue to struggle with cloud cover, most areas slightly more inland and well into the interior will see quicker clearing times. This will place most areas back into the 60s and 70s into the next work week, while the coast will stick to around 60 degree highs. By the late week, some of those more interior locations look to break into the low 80s.

Longer term models are in better agreement that the next rain maker may just stay well to the north of the Bay Area and Central Coast as the ECMWF model families have adjusted the next trough to arrive over Seattle rather than the Bay area.

AVIATION
(18Z TAFS)
Issued at 1031 AM PDT Fri Apr 26 2024

Currently a mix of VFR and MVFR at the terminals. A weak cold front that is moving through the region is allowing for strong and gusty northwesterly winds as well as isolated drizzle or light rain showers in terrain favored locations. Gusts of 30-40 knots are to be expected at the northwest wind favored locations of OAK, SFO, SJC, and SNS with APC, LVK, MRY, and STS slated to see 20-30 knot gusts.
Winds will begin to diminish this evening. VFR through the TAF period at all terminals except MRY and SNS.

Vicinity of SFO...Currently MVFR with gusty westerly winds. After this stratus moves out, VFR through the TAF period. Winds will continue to ramp up through the morning with gusts up to 40 knots to be expected through 05Z. Winds will slowly begin to diminish overnight with breezy WNW winds prevailing tomorrow.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently MVFR with gusty westerly winds at both terminals. SNS will be clearing out shortly and reamin VFR until the overnight hours tonight. MRY will likely see an MVFR ceiling through the entirety of the TAF period except for sporadic periods of brief clearing between patches of stratus. Winds will be gusty out of the west/northwest for MRY and gusty out of the west for SNS through today. Winds begin to diminish during the overnight hours.
