Area Forecast Discussion National Weather Service San Francisco Bay Area 430 AM PST Mon Mar 8 2021

SYNOPSIS. Tonight remains dry with cool temperatures. An offshore low will start to bring rain to the region Monday afternoon/evening. Cool and showery weather will continue through Wednesday as the low moves inland. There is potential for thunderstorms on Tuesday and Wednesday with lightning, gusty winds, and small hail. Drier and warmer conditions are forecast later in the week.

DISCUSSION. as of 03:22 AM PST Monday . A weak dry cold front passed through the region overnight resulting in a few high clouds. Despite the cold front temperatures are running a few degrees warmer than Sunday morning due to high clouds and a more mixed atmosphere. Interior valleys will still reach the 30s, but less likely to see spots hit freezing or sub-freezing temperatures. After a pleasant weekend weather wise today will kick off a pattern change with cooler and unsettled weather returning.

The longwave pattern over the West shows a rather robust upper low spinning off the PacNW Coast. This storm system's associated cold front is draped to the south and southwest. The front is forecast to move south and east through the day today bringing light showers to the Bay Area. Onset of shower activity has not changed much from the previous forecast. Rain showers, which are just showing up on the KBHX radar, will enter the North Bay mid- morning then spread southward during the afternoon. For most of the Bay Area (S of the Golden Gate) most of today will be dry, well at least through mid to late afternoon. Locations to the south are more likely to see shower activity Monday night into Tuesday. It should also be noted that the front is forecast to weaken as it moves southward.

The upstream upper low is forecast to track southward as the cold front moves inland on Tuesday. The upper low will bring much better dynamics and lift to the region resulting in better chances for rainfall. As noted on previous discussions, this upper low is rather cold aloft resulting in better instability and lower snow levels. The forecast has carried thunderstorms for a few days now for Tuesday and the current forecast will do the same. As the cold air aloft moves in overhead on Tuesday instability increases at the surface and aloft. The ECMWF Extreme Forecast Index, National Blend of Models, HREF (ensembles), and deterministic models all show a solid uptick in CAPE through the day Tuesday. Therefore, thunderstorms will be possible with greatest threat during the day Tuesday afternoon. Main threats with developed cells will be heavy rain, gusty winds, small hail, and lightning. Given the lower snow levels hail could accumulate rather quickly in stronger cells. Additionally, some of the lightning guidance from the ECMWF also indicates a decent likelihood for a strike or two. Back to snow levels - they're projected to drop to 3000-3500 feet during the day on Tuesday. Snow will be likely over the higher terrain with some accumulations possible, especially the Gabilan and Santa Lucia Ranges. One final note for Tuesday - not an AR set up or NCFR set up for debris flow concerns, but given the thunderstorm threat burn areas will be watch very closely. Strong cell at the wrong place could cause a problem.

Shower activity will continue through Wednesday as the core of the cold upper low passes overhead. One change to the Wednesday forecast was to keep thunderstorm chances in the forecast, especially inland area. Same threats apply: heavy rain, gusty winds, small hail, and lightning. Storm Prediction Center has much of the region in a general mention for thunderstorms on Tuesday and Wednesday. Snow levels drop 500-700 feet on Wednesday as the coldest air filters overhead.

There still remains the possibility of a few lingering showers Wednesday night into early Thursday as the upper low finally moves inland toward the Desert SW. When it's all said and done rainfall totals from Monday through early Thursday will range from 1"-2" North Bay Mts and coastal Mts with a few jackpots up to 3" per hi- res models. Interior valleys and lower elevations generally in the 0.25"-0.75" range. Obviously amounts could be locally higher given the thunderstorm threat. Snowfall totals will be tricky as sfc temps may hamper accumulating snow. Nonetheless a few inches will be possible over the North and East Bay. The Santa Lucia and S Gabilan Range could see 5-10".

Drier weather briefly returns on Friday and Saturday. Previous forecast look dry,but latest ensemble forecast shows rain chances returning late Saturday night and Sunday. At this time, chances are low and the storm system doesn't look strong, but a slight chance for rain has been added to the forecast.

AVIATION. as of 4:29 AM PST Monday . For the 12Z TAFs. VFR prevailing with areas of MVFR cigs and isolated IFR/LIFR with fog. Night satellite imagery reveals few-sct high clouds overhead and sct areas of stratus/fog. Cigs that have formed have been very patchy, and this will be the trend through the morning. Fog seems to be settling in KSTS, but is not observed or reported in other terminals. Winds are calm to light southwesterly. Low clouds should mostly clear out by mid-morning, with high clouds approaching from the north this afternoon and evening. The associated low pressure system will bring scattered rain showers to North Bay this afternoon and the rest of the Bay Area this evening. Cigs will be VFR this afternoon/early evening, lowering to MVFR overnight. Breezy W to SW winds forecast throughout much of the day and evening.

As a heads up, beyond this taf cycle expect nearly continuous cold air advection to Wed/Thu; pilots can expect low to very low freezing levels, instability and snow showers as well as a slight chance of thunderstorms especially 12z Tue-12z Wed per recent Storm Prediction Center convective outlook.

Vicinity of KSFO . VFR with few-sct at 3000 ft AGL and BKN-OVC above 4000 ft AGL. May see some partial clearing through the morning, before cigs fill in again and lower this afternoon and evening. Scattered showers arrive this evening around 03z. Winds 10-15 kt out of the WSW this afternoon and evening.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR prevailing with MVFR cigs possible through early morning. Mostly clear skies this afternoon and early evening, before high cigs arrive. Scattered showers late evening and overnight, with steadier rain Tuesday. Light to breezy winds this afternoon out of the WSW.

MARINE. as of 02:50 AM PST Monday . Moderately breezy west to northwest winds will back to the southwest this morning as a low pressure system approaches from the northwest. Showers arrive to the northern coastal waters this afternoon, and spread southward through the evening. Steadier rain arrives Tuesday with a chance of thunderstorms. Showers will continue into Wednesday. Another moderate period northwest swell arrives today, bringing continued hazardous seas conditions for smaller vessels.
