AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1049 PM PDT MON MAR 20 2023 [HEAD]

Synopsis. High winds and widespread rainfall tomorrow, with High Wind Warnings out for the Monterey and San Benito Mountains and Wind Advisories from the San Francisco Bay Area to the Monterey County coast. Scattered showers persist into Wednesday and unsettled pattern continues into next week. Monitoring potential for unseasonably cold temperatures next weekend, and a new storm system the beginning of next week. 

.SYNOPSIS...HIGH WINDS AND WIDESPREAD RAINFALL TOMORROW, WITH HIGH
WIND WARNINGS OUT FOR THE MONTEREY AND SAN BENITO MOUNTAINS AND WIND
ADVISORIES FROM THE SAN FRANCISCO BAY AREA TO THE MONTEREY COUNTY
COAST. SCATTERED SHOWERS PERSIST INTO WEDNESDAY AND UNSETTLED
PATTERN CONTINUES INTO NEXT WEEK. MONITORING POTENTIAL FOR
UNSEASONABLY COLD TEMPERATURES NEXT WEEKEND, AND A NEW STORM SYSTEM
THE BEGINNING OF NEXT WEEK. [DISC]

Discussion. As of 08:49pm PDT Monday… a few notable shifts among high resolution guidance this evening helps to bring a little more confidence in the forecast. At this point, it seems likely that the surface low will move into the coastal region very near the SF Peninsula. A low coming onshore in this location would still keep the highest winds to the south of the Bay Area proper, though with antecedent conditions, still expect impacts due to downed trees and power lines across the Bay Area. For now, kept the Bay Area and surrounding coastline under High Wind Advisory, while upgrading the Big Sur coast, southern Monterey Bay, and northern Salinas Valley to be included in the High Wind Warning. Highest winds in these areas still expected to be along the Big Sur coast, Santa Lucia Range, San Benito County, and towards the northern end of the Salinas Valley including the central Monterey Bay coastline. 

.DISCUSSION...AS OF 08:49 PM PDT MONDAY...A FEW NOTABLE SHIFTS
AMONG HIGH RES GUIDANCE THIS EVENING HELPS TO BRING A LITTLE MORE
CONFIDENCE IN THE FORECAST. AT THIS POINT, IT SEEMS LIKELY THAT
THE SURFACE LOW WILL MOVE INTO THE COASTAL REGION VERY NEAR THE SF
PENINSULA. A LOW COMING ONSHORE IN THIS LOCATION WOULD STILL KEEP
THE HIGHEST WINDS TO THE SOUTH OF THE BAY AREA PROPER, THOUGH
WITH ANTECEDENT CONDITIONS, STILL EXPECT IMPACTS DUE TO DOWNED
TREES AND POWER LINES ACROSS THE BAY AREA. FOR NOW, KEPT THE BAY
AREA AND SURROUNDING COASTLINE UNDER HIGH WIND ADVISORY, WHILE
UPGRADING THE BIG SUR COAST, SOUTHERN MONTEREY BAY, AND NORTHERN
SALINAS VALLEY TO BE INCLUDED IN THE HIGH WIND WARNING. HIGHEST
WINDS IN THESE AREAS STILL EXPECTED TO BE ALONG THE BIG SUR COAST,
SANTA LUCIA RANGE, SAN BENITO COUNTY, AND TOWARDS THE NORTHERN
END OF THE SALINAS VALLEY INCLUDING THE CENTRAL MONTEREY BAY
COASTLINE. [DISC]

Another noteworthy bit to add… our criteria for bomb cyclogenesis [formation or intensification of a cyclone or low-pressure storm system] at this latitude is about 17 millibars in 24 hours. Current model guidance does suggest this will happen during a short period Tuesday morning, though impacts remain the same regardless of if we technically meet this criteria or not. 

ANOTHER NOTEWORTHY BIT TO ADD...OUR CRITERIA FOR BOMB
CYCLOGENESIS AT THIS LATITUDE IS ABOUT 17 MILLIBARS IN 24 HOURS.
CURRENT MODEL GUIDANCE DOES SUGGEST THIS WILL HAPPEN DURING A
SHORT PERIOD TUESDAY MORNING, THOUGH IMPACTS REMAIN THE SAME
REGARDLESS OF IF WE TECHNICALLY MEET THIS CRITERIA OR NOT. [DISC]

Previous discussion… as of 03:11pm PDT Monday. A break in the rain for the rest of today as winds remain light and mainly clear, with highs in the lower elevations in the mid 50s to low 60s, and into the mid 40s to low 50s for the higher elevations. 

.PREV DISCUSSION...AS OF 03:11 PM PDT MONDAY...A BREAK IN THE RAIN FOR THE
REST OF TODAY AS WINDS REMAIN LIGHT AND MAINLY CLEAR, WITH HIGHS IN
THE LOWER ELEVATIONS IN THE MID 50S TO LOW 60S, AND INTO THE MID 40S
TO LOW 50S FOR THE HIGHER ELEVATIONS. [DISC]

A storm system is approaching California and will impact the SF Bay Area and Central Coast starting early on Tuesday. While the system is associated with an atmospheric river approaching the state, the main moisture tap will be directed to our south in Southern California and Baja California. For our area, winds will be the main issue, with the most impactful gusts Tuesday morning into the afternoon. A High Wind Warning is in effect from 7am to 9pm Tuesday in the mountains of Monterey and San Benito Counties, where southerly gusts of over 70 mph are expected. Elsewhere, a Wind Advisory is in effect for the East and South Bay, the San Mateo peninsula, and the lower elevations of the Central Coast, also from 7am to 9pm Tuesday, with southerly wind gusts of up to 40–50 mph are expected, with more intense gusts in the higher elevations. The North Bay should see gusts of up to 20–25 mph. Much of the uncertainty in the strength of the wind gusts is in the wider SF Bay region, as models are still having difficulty on the location of a surface low that's expected to enhance wind gusts. The global GFS [Global Forecast System: global spectral model used primarily for aviation weather forecasts; provides guidance out to 384 hours at 00, 06, 12 and 18UTC.] and European models are bringing the low to a stall off the coast of the San Mateo peninsula, while the higher resolution HRRR and NAM [North American Meso (formerly Eta) model] are bringing the low onshore along the Central Coast. We will continue to closely monitor the surface low and its evolution as the impact comes closer. 

A STORM SYSTEM IS APPROACHING CALIFORNIA AND WILL IMPACT THE SF BAY
AREA AND CENTRAL COAST STARTING EARLY ON TUESDAY. WHILE THE SYSTEM
IS ASSOCIATED WITH AN ATMOSPHERIC RIVER APPROACHING THE STATE, THE
MAIN MOISTURE TAP WILL BE DIRECTED TO OUR SOUTH IN SOUTHERN
CALIFORNIA AND BAJA CALIFORNIA. FOR OUR AREA, WINDS WILL BE THE MAIN
ISSUE, WITH THE MOST IMPACTFUL GUSTS TUESDAY MORNING INTO THE
AFTERNOON. A HIGH WIND WARNING IS IN EFFECT FROM 7 AM TO 9 PM
TUESDAY IN THE MOUNTAINS OF MONTEREY AND SAN BENITO COUNTIES, WHERE
SOUTHERLY GUSTS OF OVER 70 MPH ARE EXPECTED. ELSEWHERE, A WIND
ADVISORY IS IN EFFECT FOR THE EAST AND SOUTH BAY, THE SAN MATEO
PENINSULA, AND THE LOWER ELEVATIONS OF THE CENTRAL COAST, ALSO FROM
7 AM TO 9 PM TUESDAY, WITH SOUTHERLY WIND GUSTS OF UP TO 40-50 MPH
ARE EXPECTED, WITH MORE INTENSE GUSTS IN THE HIGHER ELEVATIONS.  THE
NORTH BAY SHOULD SEE GUSTS OF UP TO 20-25 MPH. MUCH OF THE
UNCERTAINTY IN THE STRENGTH OF THE WIND GUSTS IS IN THE WIDER SF BAY
REGION, AS MODELS ARE STILL HAVING DIFFICULTY ON THE LOCATION OF A
SURFACE LOW THAT`S EXPECTED TO ENHANCE WIND GUSTS. THE GLOBAL GFS
AND EUROPEAN MODELS ARE BRINGING THE LOW TO A STALL OFF THE COAST OF
THE SAN MATEO PENINSULA, WHILE THE HIGHER RESOLUTION HRRR AND NAM
ARE BRINGING THE LOW ONSHORE ALONG THE CENTRAL COAST. WE WILL
CONTINUE TO CLOSELY MONITOR THE SURFACE LOW AND ITS EVOLUTION AS THE
IMPACT COMES CLOSER. [DISC]

Rainfall will be a secondary impact in our area, although expected totals are not as high as those in Southern California. Here too, the most intense rain is expected Tuesday morning and afternoon. The lower elevations of the North Bay, SF Bay Area, and Central Coast are currently forecast to see three-quarters of an inch to one inch of rain, save for the most northern parts of Sonoma County where rain totals go down to half an inch. The Central Coast Mountains remain the regional epicenter of rain impacts, with rain totals in the Santa Lucia Mountains expected to range from 2–3 inches, and the Santa Cruz and interior Monterey and San Benito Mountains expected to reach 1.5–2.5 inches of rain. Higher elevations in the Bay Area should expect 1–2 inches of rain. A slight chance of thunderstorms exists into the post-frontal environment on Tuesday evening, especially on the Central Coast. 

RAINFALL WILL BE A SECONDARY IMPACT IN OUR AREA, ALTHOUGH EXPECTED
TOTALS ARE NOT AS HIGH AS THOSE IN SOUTHERN CALIFORNIA. HERE TOO,
THE MOST INTENSE RAIN IS EXPECTED TUESDAY MORNING AND AFTERNOON. THE
LOWER ELEVATIONS OF THE NORTH BAY, SF BAY AREA, AND CENTRAL COAST
ARE CURRENTLY FORECAST TO SEE THREE-QUARTERS OF AN INCH TO ONE INCH
OF RAIN, SAVE FOR THE MOST NORTHERN PARTS OF SONOMA COUNTY WHERE
RAIN TOTALS GO DOWN TO HALF AN INCH. THE CENTRAL COAST MOUNTAINS
REMAIN THE REGIONAL EPICENTER OF RAIN IMPACTS, WITH RAIN TOTALS IN
THE SANTA LUCIA MOUNTAINS EXPECTED TO RANGE FROM 2 TO 3 INCHES, AND
THE SANTA CRUZ AND INTERIOR MONTEREY AND SAN BENITO MOUNTAINS
EXPECTED TO REACH 1.5 TO 2.5 INCHES OF RAIN. HIGHER ELEVATIONS IN
THE BAY AREA SHOULD EXPECT 1 TO 2 INCHES OF RAIN. A SLIGHT CHANCE OF
THUNDERSTORMS EXISTS INTO THE POST-FRONTAL ENVIRONMENT ON TUESDAY
EVENING, ESPECIALLY ON THE CENTRAL COAST. [DISC]

The combination of continued rain, high winds, and saturated soils poses a set of hazards that, at this point, are now familiar to many in our region. The rain brings a chance for minor urban and small stream flooding, and with soils already so saturated from the storms earlier this month, the risk of shallow landslides continue. High wind gusts will also result in downed trees and power lines, possibly resulting in isolated power outages, and difficult driving for high profile vehicles. If your area is prone to power outages, use today to prepare, and remember to "turn around, don't drown" when encountering a flooded roadway or path. 

THE COMBINATION OF CONTINUED RAIN, HIGH WINDS, AND SATURATED SOILS
POSES A SET OF HAZARDS THAT, AT THIS POINT, ARE NOW FAMILIAR TO MANY
IN OUR REGION. THE RAIN BRINGS A CHANCE FOR MINOR URBAN AND SMALL
STREAM FLOODING, AND WITH SOILS ALREADY SO SATURATED FROM THE STORMS
EARLIER THIS MONTH, THE RISK OF SHALLOW LANDSLIDES CONTINUE. HIGH
WIND GUSTS WILL ALSO RESULT IN DOWNED TREES AND POWER LINES,
POSSIBLY RESULTING IN ISOLATED POWER OUTAGES, AND DIFFICULT DRIVING
FOR HIGH PROFILE VEHICLES. IF YOUR AREA IS PRONE TO POWER OUTAGES,
USE TODAY TO PREPARE, AND REMEMBER TO "TURN AROUND, DON`T DROWN"
WHEN ENCOUNTERING A FLOODED ROADWAY OR PATH. [DISC]

The heaviest rain diminishes Tuesday evening, with post frontal showers expected through Wednesday. Current predictions leave Thursday to Saturday relatively dry with very little, if any, rain. Any rain that falls in the next three days is not expected to rise past half an inch in total. All attention then focuses on the beginning of the next week, where early model indications suggest another system coming through, the exact details of which won't become clear until later in the week. In addition, low temperatures next weekend are expected to dip into unseasonably cold readings, with lows in the low to mid 30s expected Saturday and Sunday morning in the interior valleys, including the Sonoma, Napa, and Salinas Valleys, and into the higher elevations. With the occurrence of "Bud break" in the North Bay vineyards, and the spring harvest approaching, this is a particularly sensitive time for the agricultural industries. More details on the low temperatures and the system next week will come as the forecast gets refined later in the week. 

THE HEAVIEST RAIN DIMINISHES TUESDAY EVENING, WITH POST FRONTAL
SHOWERS EXPECTED THROUGH WEDNESDAY. CURRENT PREDICTIONS LEAVE

Aviation. As of 10:50pm PDT Monday… for the 00Z [5pm PDT] TAFs [Terminal Aerodrome Forecasts]VFR [Visual Flight Rules] lasts into early Tuesday morning. Easterly and southeasterly winds begin to increase as a strong surface low approaches. This low pressure system will bring moderate to heavy rain starting early morning lasting through the afternoon with scattered showers continuing through the evening and lingering into the night. Expect MVFR [Marginal Visual Flight Rules] ceilings for most of the TAF [Terminal Aerodrome Forecast] period. As the center of the low moves inland, southerly winds will increase. Strong gusts of 35–40 knots [40–46 mph] possible across the region, primarily south of the Golden Gate. Winds begin to diminish int Tuesday night.
