SYNOPSIS
Issued at 118 AM PDT Mon Apr 22 2024

Warm inland temperatures expected through today before cooler, unsettled weather returns Tuesday and continues through late week.
Light rain chances for Thursday night and into Friday.

UPDATE
Issued at 748 PM PDT Mon Apr 22 2024

The southerly wind reversal is in full effect this evening with low stratus clouds banked along the shoreline and spilling inland around the Monterey Bay, along the North Bay Coast, and through the Golden Gate. Inland stratus intrusion will continue overnight with most lower elevations covered given the deepening marine layer. There should be enough moisture for some coastal drizzle as well, especially along south/west facing slopes. This is all well captured via the going forecast, so no changes are necessary this evening.

SHORT TERM
(This evening through Tuesday)
Issued at 256 PM PDT Mon Apr 22 2024

Primarily sunny across inland areas with clouds lingering along the coastline and the Central Coast. Looking at satellite shows the southerly surge of stratus in action with stratus extending northwards from southern California to the North Bay coastline. As of 2PM, inland temperatures are in the upper 60's to low 80's while temperatures are in the low to mid 60's along the coast. Widespread stratus will move inland by late this evening/overnight throughout the majority of the Bay Area. HRRR guidance suggests that cloud coverage will be patchier in nature throughout the Santa Clara Valley. Monday night into Tuesday, orographic lifting will help to generate light drizzle across coastal regions with precipitation accumulations of a few hundredths of an inch expected.

An upper level disturbance will approach the coast beginning Tuesday and lead to a pattern shift from above normal temperatures to below normal temperatures. While Monday's highs were 5 to 10 degrees above normal, Tuesday's highs are forecast to be, on average, 5 to 15 degrees below normal. High temperatures along the coast will linger in the upper 50's to low 60's while highs inland will stay in the 60's with a few areas potentially reaching the low 70's.

LONG TERM
(Tuesday night through next Sunday)
Issued at 256 PM PDT Mon Apr 22 2024

Cooler, unsettled conditions will continue through Friday as an upper level disturbance moves inland. High temperatures throughout the work week will stay in the 60's inland and in the upper 50's to low 60's along the coastline. Low temperatures will stay in the mid 40's to low 50's with a few locations in mountainous terrain dropping into the low 40's. Guidance continues to indicate some light precipitation is likely Thursday into Friday but confidence remains mixed as to how much precipitation will actually occur. The most recent run of the ECMWF shows light, scattered showers moving over the Bay Area with amounts generally receiving less than 0.15 to 0.25 inches.

Temperatures will gradually start to rise and become closer to normal towards the end of the weekend with highs returning to the upper 60's to low 70's.

AVIATION
(06Z TAFS)
Issued at 1025 PM PDT Mon Apr 22 2024

Robust surface to lower level cool air advection will deepen the marine layer and fully weaken/mix out the marine layer temperature inversion tonight. Stratus will move inland, cool air advection and upsloping flow resulting in patchy drizzle. Radiative warming returning Tuesday will result in plenty of mixing with sufficiently drier air resulting in VFR conditions Tuesday.

Vicinity of SFO...VFR at the moment with MVFR stratus hanging along the coast. There is a decent chance this stratus reaches the terminal tonight, and with the deep marine layer, it may even produce some light drizzle in the early morning. Flight conditions will improve through the day Tuesday with a moderate onshore breeze.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...The early return of stratus has materialized tonight and MRY, SNS and WVI are all under a dense MVFR ceiling. The deep marine layer is expected to persist through Tuesday, although there may be some improvement as daytime heating mixes out some of the clouds.

MARINE
(Tonight through next Sunday)
Issued at 1025 PM PDT Mon Apr 22 2024

Southerly winds continuing over the coastal waters into Tuesday, gusty near Point Sur Tuesday afternoon. Starting Wednesday, winds turn once more to become moderate and northerly. Light southerly swell continues to move through the waters for much of the week.

MTR WATCHES/WARNINGS/ADVISORIES
