New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 1215 AM PST Wed Nov 29 2023
Showers will persist through the first half of today. An unsettled pattern will continue into the weekend with cooler temperatures.
SHORT TERM
(Today and tonight)
Issued at 1215 AM PST Wed Nov 29 2023
A closed upper low was evident via moisture channel imagery early this morning just off the Mendocino Coast with an occluded front located west of the Bay Area in association with the attendant surface low. A leading band of showers was progressing inland across the Bay Area as of this writing with additional scattered showers located offshore. The upper low is forecast to devolve to an open- wave trough while sinking southeast towards the Central Coast with the associated surface front remaining just offshore. Scattered showers will gradually taper off from northwest to southeast from late morning into early afternoon as forcing for ascent gradually wanes. Given cold temperatures aloft and steepening lapse rates still can't rule out an isolated thunderstorm or two primarily over the Pacific waters as modest instability builds. That said scattered light showers will be the primary weather most folks should experience today. Total rain amounts still look to average 0.5" or so within the coastal ranges with most lower elevations seeing 0.25" or less. Typically rain shadowed/drier locations like the Santa Clara and Salinas Valleys are likely to see 0.15" or less through this evening. Temperatures this afternoon should be seasonal with highs mostly in the lower 60s. Partial clearing this evening should allow for overnight lows to dip into the 40s for most areas, with a few of the typically colder inland spots dropping into the upper 30s.
LONG TERM
(Thursday through Tuesday)
Issued at 1215 AM PST Wed Nov 29 2023
The region will remain in an unsettled northwest flow pattern aloft as a series of weak perturbations traverse the mean flow. In general the best moisture and forcing for ascent will remain across far NorCal and the Pacific Northwest, however we'll remain just close enough to occasionally be brushed with some light showers. Rain amounts don't appear overly impressive (generally 0.10" or less)
although it's possible the Sonoma Coastal Ranges could receive up to 0.25" through early next week. A period of breezy onshore winds is expected late Thursday into Friday as upper troughing swings through the Great Basin and surface high pressure strengthens over the northeast Pacific. Expect a gradual warming trend in temperatures through early next week as the greatest rain chances shift north of all but far northern portions of the Bay Area.
AVIATION
(06Z TAFS)
Issued at 830 PM PST Tue Nov 28 2023
VFR through the TAF period. The oncoming low pressure system continues to slow, delaying the start times of the winds shifts and initial rain chances. Expect showers to move through the North Bay into the late night and slowly spread south through the night. Showery conditions will be widespread early Wednesday but will thin out in the mid to late morning. Consistent lowered CIGs are not expected with this system, but passing lower clouds will be possible. Expect weak winds into Wednesday afternoon with clearing skies. High clouds build late Wednesday with some areas seeing moderate evening winds.
Vicinity of SFO...VFR through the TAF period. Southwest winds turn southeast as the showers arrive in the late night.
Expect some lingering showers in the mid morning with easterly winds that become light and variable into Wednesday afternoon.
Moderate northwesterly winds return Wednesday night.
SFO Bridge Approach...Similar to SFO
Monterey Bay Terminals...VFR through the TAF period. Winds stay light and variable into the night, but increase and become southeasterly as the showers arrive in the late night and early morning. Rain chances last into Wednesday afternoon before exiting. Expect light winds and lingering high clouds into Wednesday night.
MARINE
(Tonight through next Sunday)
Issued at 817 PM PST Tue Nov 28 2023
Moderate to breezy winds continue to affect the waters as a low pressure system approaches. Scattered showers move through the area late tonight and last through much of Wednesday morning. An isolated thunderstorm or two is possible during this time. Winds gradually diminish and shift north late Wednesday into Thursday before strong breezes develop by Thursday night. A larger moderate period northwest swell arrives in the late week. Weather conditions will remain unsettled into the weekend.
