Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
a low pressure system continues to approach the california coast. The main band of moderate to heavy rain and gale force gusts is moving through the waters and will pass by the evening. Cold, unstable air aloft with the low will also result in a slight to moderate chance of Thunderstorms this afternoon, tonight and Saturday. Isolated severe Thunderstorms, with increasing potential for hail and a slight potential for waterspout development, will increase in likelihood through the evening. A high pressure system will build in behind the low late in the weekend and early next week bringing drier, milder conditions to the area.

SYNOPSIS
Issued at 237 PM PDT Fri Mar 29 2024
A low pressure system with gale force winds is located approximately 250 miles to west of San Francisco. As this system approaches, it will bring widespread moderate to locally heavy rain, gusty winds, and a few thunderstorms. Moderate impacts are anticipated including minor flooding in urban areas and some potential for tree/power line damage. Remember to stay up to date on the current forecast and prepare for longer afternoon and evening commutes.
SHORT TERM
(This evening through Saturday)
Issued at 237 PM PDT Fri Mar 29 2024
The latest surface analysis from the Weather Prediction Center shows the low pressure system located approximately 250 miles west of San Francisco. Radar shows prefrontal widespread moderate to heavy rain showers have developed ahead of the surface warm front. Showers have already reached portions of the North Bay and San Francisco Peninsula with 6 hour rain totals between 0.5-0.9 inches in portions of the North Bay and Santa Cruz Mountains. These showers will continue to move inland over the next several hours. The warm front is expected to pass through the SF Bay Area by the late afternoon (approximately 4-5 PM).
After warm frontal passage, destabilization is expected to occur over the marine environment and thunderstorm chances increase significantly. Model guidance from the HRRR suggests that as the atmosphere destabilizes over the marine environment, convection will become more scattered and allow for the development of isolated stronger thunderstorms. The best window for thunderstorm development has shifted slightly later from this morning with the best window (20-35% chance) now occurring between 5PM this evening through 8PM on Saturday. Current data from SFO and KMUX shows moderate surface to 6km speed and directional shear, suggesting the formation of a more favorable environment for thunderstorm development. As a more strongly sheared and higher CAPE environment develops over the marine environment, the likelihood of waterspout development increases so we cannot rule out the potential for a landfalling waterspout.
Velocity radar data shows widespread winds between 30 to 55 mph moving onshore with the potential for locally higher winds to develop due to terrain or shower influences. A Wind Advisory remains in effect until 5AM Saturday for gusts 50+ mph in the highlands (elevated interior terrain and coastal mountains) and 45+ mph in the lowlands. A High Wind Warning is in effect along the Big Sur coast for gusts up to 60 mph. As these strong, gusty winds move inland there is increased likelihood of damage to trees and power lines.
Nuisance flooding may occur as heavier showers move through urban areas but widespread river flooding is not expected.
Remember to stay up to date with the forecast and any watches/warnings as the system continues to move through our area.
LONG TERM
(Saturday night through next Thursday)
Issued at 237 PM PDT Fri Mar 29 2024
Scattered showers will continue Saturday into Sunday with elevated thunderstorm chances continuing until 8PM on Saturday. While thunderstorm chances are slightly lower on Saturday (20-25% chance)
than Friday (20-35% chance), cannot rule out the possibility of isolated strong thunderstorms developing. Given the scattered nature of these showers, some sunny breaks in between showers may be possible, but remember to stay weather aware and carry an umbrella with you in preparation for additional future showers. For hydrologic concerns, some potential remains for nuisance flooding overnight Friday into Saturday particularly if stronger showers move over urban areas.
Showers will start to lighten up throughout the day on Saturday with light showers expected through early Sunday morning. By Sunday morning, most showers will have departed the area but a few isolated light showers (< 0.1 inches) may linger into the early afternoon hours. Winds will start to relax heading into Sunday as the pressure gradient weakens. Temperatures will be on the cooler side with highs in the upper 50's to low 60's and lows mostly in the 40's.
Sunday through Thursday:
High pressure will start to build during the early work week and bring in drier, warmer weather across the region. Guidance hints that unsettled weather will return towards the end of the work with cooler temperatures and some light rain possible.
AVIATION
(00Z TAFS)
Issued at 419 PM PDT Fri Mar 29 2024
Moderate to heavy rain associated with an occluded front continues to move through the interior East Bay, the South Bay and down through the Central Coast. MVFR ceilings and showers are developing behind the front, with an increasing chance of thunderstorm activity into Saturday. Strongly gusty southeasterly winds continue for the rest of the day, with winds diminishing somewhat overnight before turning more easterly and becoming gusty again Saturday. Wind shear across the Bay Area should begin to diminish as the main frontal system passes.
Vicinity of SFO... Radar returns show that the main frontal rain band has moved to the east of SFO. Expect showers through Saturday and a chance for thunderstorms through the evening hours tonight, a lesser chance returning on Saturday. Conditions will predominantly remain VFR with some chance of MVFR if a shower forms at the terminals. Strong gusty southeast winds will continue across the terminal through the night and will begin to turn to the northeast and diminish Saturday afternoon and evening. AWW is out through 2Z but may need to be extended pending evolution of local thunderstorm activity.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... VFR to MVFR in rain showers. Gusty southeast winds continue through the TAF period with a brief early morning lull at MRY. Continuing to monitor SNS winds with the continuing southeast orientation. Chance of thunderstorms now through Saturday morning.
