a brief break in the rain will continue into the overnight period before light to moderate precipitation returns early Friday morning. Gentle to moderate northwesterly breezes continue tonight before moderate to strong southwesterly winds develop ahead of the incoming low pressure system. Gale force gusts will become more likely, particularly across the southernmost marine zones Friday into Saturday, with isolated gale force gusts possible across the northernmost zones. Thunderstorm chances are highest (25 to 30 percent chance) over the coastal waters on Friday with a 15 to 25 percent chance on Saturday. Wave heights will continue to build through the early work week before starting to diminish.

New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 859 PM PDT Thu Mar 28 2024
Some isolated showers overnight with increasing clouds. Southerly winds ramp up Friday morning ahead of the next strong frontal boundary with Wind Advisories going into effect for much of the region due to forecast wind gusts to 45 mph. Steady rain develops along the coast by mid-morning and spreads inland with numerous showers and thunderstorms Friday night into Saturday.
Precipitation will gradual taper from north to south by Saturday night as the low drops southward. High pressure builds Sunday through Wednesday with a return to more springlike temperatures and dry weather.
SHORT TERM
(Tonight through Saturday)
Issued at 859 PM PDT Thu Mar 28 2024
Main forecast update this evening was to extend the areal coverage of the Wind Advisory. The Sonoma/Marin coast and hills have been added as well as the City of San Francisco, eastern Santa Clara hills and the Salinas Valley. The 00z nam guidance has arrived and latest projections show the deepening surface low taking a slightly more northerly tract towards the Sonoma coast by Friday afternoon. No matter the track strong southerly winds will developing around the deepening low. 925 mb winds in the 40-45 kt range suggests we will see widespread surface gusts to at least 45 mph that will be enhanced by local topography, especially along the coast and wind funneled valleys like the Salinas valley.
Timing of strongest winds looks to be Friday afternoon and evening then easing late tomorrow night.
Surface pressure over the ocean is currently around 1012-1015 mb and the incoming low will drop to around 995 mb. So we wont be in bomb status but a rapidly deepening surface low that will produce a well organized rain shield with favorable upper level jet dynamics. The afternoon commute will get messy with wet roads and periods of moderate to heavy rain. By later afternoon and evening hours we should see numerous lightning strikes develop offshore and push inland as the cold core upper low gets closer to the coast. So as the steady rain ends it will be replaced by an unstable airmass with numerous showers and t-storms Friday evening. Biggest impact will be small hail that can quickly cover roadways. If you encounter hail covered roads your best course of action is to slow down and consider pulling over.
As the low drops down the coast Friday night into Saturday precip will gradually diminish from north to south. Saturday will not be a complete wash out but plenty of showers and t-storms are forecast with the cold low staying just offshore. Storm total rainfall of 0.50-1.00 for the valleys with 1-3 inches coastal hills and some bullseye high amounts of 4-5 inches for the Santa Cruz and Santa Lucia mountains above Big Sur.
LONG TERM
(Saturday night through next Thursday)
Issued at 859 PM PDT Thu Mar 28 2024
Some lingering showers Saturday night but on the decrease as cyclonic flow exits the region. High pressure builds Sunday leading to a nicer end to the weekend weather wise.
Spring like Monday through Weds with sunshine and temps warming into the 70s. Long range suggest another cool trough by Thursday with a chance of some showers by next Friday.
AVIATION
(00Z TAFS)
Issued at 429 PM PDT Thu Mar 28 2024
Isolated showers continue across the North Bay and parts of the wider SF Bay Area. These showers should diminish through the evening before an incoming low pressure system parallels the California coast beginning on Friday. Pre-frontal showers should begin around 12-14Z with stronger and more consistent rain coming spreading across the region starting Friday afternoon. Breezy northwesterly winds will diminish overnight, then turning to the south to southeast on Friday with strong gusts expected in the afternoon and evening. Generally VFR conditions continue with the potential for MVFR ceilings with the pre-frontal showers, with MVFR ceilings becoming widespread as the main rain band comes through the region.
Vicinity of SFO... Expecting VFR with breezy west-northwest winds through the evening, winds diminishing early overnight. Pre-frontal showers develop around 12-14Z Friday, with more intense and consistent rain coming through Friday afternoon and evening. Winds turn towards the southeast and become highly gusty. Have opted for wind speeds slightly stronger than model outputs based on recent history of SFO tending to outdo the models. Currently put gusts up to 30 knots in the TAF, but would not be surprised to see gusts rise above 35 knots. After the main rain band passes, expect continuing showers and thunderstorms through and beyond the end of the TAF period.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... VFR with breezy northwest winds through the evening, winds diminishing overnight. Pre-frontal showers arrive Friday morning with more consistent rain coming near or at the end of the TAF period. Winds will turn to the southeast on Friday with strong gusts, up to 25 knots at MRY and perhaps 35 knots at SNS.
MARINE
(Tonight through next Tuesday)
Issued at 429 PM PDT Thu Mar 28 2024
Scattered showers continue over the coastal waters with a brief break expected this evening before light to moderate precipitation returns on Friday. Gentle to moderate northwesterly breezes continue through Thursday evening before moderate to strong southwesterly winds develop ahead of the incoming low pressure system. Gale force gusts will become more likely, particularly across the southernmost marine zones, Friday into Saturday with isolated gale force gusts possible across the northernmost zones.
Thunderstorm chances are highest (25 to 30 percent chance) over the coastal waters on Friday with a 15 to 25 percent chance on Saturday. Wave heights will continue to build through the early work week before starting to diminish.
