Area Forecast Discussion National Weather Service San Francisco Bay Area 340 PM PST Sun Jan 16 2022

SYNOPSIS.

Mild again today with more sunshine. Slight chances for drizzle again for Monterey Co, Monday. Otherwise mostly dry and mild this week with high pressure in control.

DISCUSSION. as of 02:00 PM PST Sunday . A 565dm 500mb low pressure system is situated approximately 325 miles WSW of downtown San Francisco early this afternoon. Moisture rotating counter clockwise around this feature is advecting northward from the subtropics (modest, but not impressive PWATs) via southern California and creating a broad shield cloud of partly to mostly cloudy skies around 8000 to 15000 feet above the surface. The combined efforts of upper level storm dynamics and embedded instability were sufficient to generate high based showers overnight and into this morning, resulting in a few rain gages reporting a trace to a few hundredths of an inch of rain. That said, the high cloud base and limited coverage meant that most areas were lucky to see a few sprinkles, if any rain whatsoever. Latest KMUX radar imagery shows extremely light returns, primarily off the coast and only a few hints across the South Bay/Central coast. May continue to see extremely isolated reports of precipitation through the day but most areas should remain dry. For tonight, can not rule out localized drizzle though accumulations, if any, will be extremely light.

This feature has been quasistationary off the southern/central California coast due to its positioning in a stubborn weather pattern known as a rex block. Consequently, this storm system will continue to linger in the vicinity through the day on Monday, so expect very similar conditions seen today (ie, mild temperatures with extremely isolated high based showers and scattered to broken mid to high level clouds) as the upper low/associated rex block slowly shift eastward. Latest model guidance indicates the offshore low pushing ashore between tomorrow afternoon and evening, meaning gradually clearing should be expected overnight tomorrow into Tuesday. That said, short term guidance from WRF/HRRR/HREF etc suggest development of low clouds/fog by late Monday night into Tuesday morning in the clearing skies in the wake of this system.

Tuesday will be a bit of a transition day as 576dm 500mb high pressure builds back into the region, promoting increasingly breezy north to northwest winds along the coast and modest warming. By Wednesday, the ridge strengthens closer to 582dm 500mb off the coast while the positively tilted ridge axis makes landfall. Temperatures will increase roughly 3-8F degrees between today and Wednesday with afternoon highs in the 60s (low 60s nearshore and upper 60s interior) as this occurs, with similar temperatures expected under the high pressure regime into the upcoming weekend. The warmest interior locations such as Pinnacles National Park could rise into the low 70s for the weekend.

AVIATION. as of 3:40 PM PST Sunday . For the 00Z TAFs. Light winds with BKN-OVC clouds around 7000 to 10000 feet this afternoon and slowly lowering. VFR cigs expected through the TAF period. Some MVFR visbys at KSFO and KLVK with haze lingering and likely to stick around tonight with the winds remaining light. Possible IFR with fog development at KSTS in the early morning. Similar story expected for tomorrow with light winds becoming more onshore.

Vicinity of KSFO . VFR to MVFR with haze lingering in the SF Bay. Light winds with continuing mid level clouds.

KSFO Bridge Approach . Similar to KSFO.

Monterey Bay . VFR, light winds, continued mid level clouds around 5000 to 8000 feet.

MARINE. as of 03:31 PM PST Sunday . Expect light and variable winds to continue across the coastal waters through early week, with some locally breezy offshore winds through coastal gaps for the next few mornings. Moderate period west to northwest swell trains will move across the waters through most of the week. West to northwest winds will increase further into the week.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. None.
