AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
957 PM PST SUN MAR 6 2016

...RAIN TONIGHT THEN SHOWERS AND ISOLATED THUNDERSTORMS MONDAY...

...STRONG AND GUSTY WINDS POSSIBLE THROUGH EARLY MONDAY MORNING...

.SYNOPSIS...A TROUGH OVER THE EASTERN PACIFIC WILL AMPLIFY AND
REACH THE NORTHERN CALIFORNIA COAST LATE TONIGHT AND MONDAY. THIS
TROUGH WILL QUICKLY DEVELOP IN TO A LOW PRESSURE CIRCULATION OVER
THE BAY AREA BY EARLY MONDAY MORNING CAUSING GUSTY WINDS...WIDESPREAD
SHOWERS...AND ISOLATED THUNDERSTORMS. THE LOW WILL BE LOCATED OVER
SOUTHERN CALIFORNIA BY LATE MONDAY AFTERNOON AND EVENING. SHOWERS
WILL TAPER OFF BY LATE MONDAY. TUESDAY AND WEDNESDAY LOOK DRY FOR
MOST OF THE REGION...ALTHOUGH RAIN CHANCES WILL CONTINUE IN THE
NORTH BAY. RAIN CHANCES WILL THEN SPREAD SOUTH ACROSS ALL OF THE
FORECAST AREA BY LATE THURSDAY.

&&

.DISCUSSION...AS OF 9:38 PM PST SUNDAY...WARM FRONTAL RAIN CONTINUES
TO SPREAD E-SE OVER THE BAY AREA THIS EVENING. MULTIPLE LIGHTNING
STRIKES HAVE OCCURRED THROUGH THE AFTERNOON AND EARLY EVENING OVER
THE EPAC /APPROX 150-300 MILES SW-W OF THE AREA/. PER IR SAT
IMAGERY THIS AREA OF LIGHTNING WAS CLOSER TO WHAT APPEARS TO BE A
BOUNDARY RACING SE AWAY FROM THE LOW LOCATED TO TO THE N-NW. A
COLD FRONT IS STILL EXPECTED TO QUICKLY SWEEP SE OVER THE AREA
LATE TONIGHT AND EARLY MONDAY MORNING. KMUX SHOWED ISOLATED ECHO
TOPS BRIEFLY REACHING 25-27 THOUSAND FEET OFF SAN MATEO AND SANTA
CRUZ COUNTIES BACK AT 8 PM...COINCIDING WITH A COUPLE LIGHTNING
STRIKES. STORM PREDICTION CENTER KEEPS OUR FORECAST AREA UNDER A
MARGINAL RISK FOR SEVERE T-STORMS THROUGH 4 AM MONDAY.

A COMPACT LOW PRESSURE SYSTEM MOVES OFF THE EPAC AND OVER THE BAY
AREA LATE TONIGHT AND MONDAY. MODELS ARE CONSISTENT WITH INDICATING
RAPID 500H COOLING AND STRONG POSITIVE VORTICITY TROUGH SWINGING
OVER THE AREA LATE TONIGHT/MONDAY SETTING THE STAGE FOR ADDITIONAL
INSTABILITY MOVING NW-SE OVER THE COUNTY WARNING. AREA OF RAIN
PRESENTLY SEEN ON KMUX WILL LIKELY ADVANCE EAST OUT OF THE AREA
PRIOR TO SHOWERS/ISOLATED T-STORMS DEVELOPING OVER NORTH BAY AREA
THEN SPREADING QUICKLY SE EARLY MONDAY MORNING. THE LOW PRESSURE
AREA WILL BE OVER SOUTHERN CALIFORNIA BY LATE MONDAY AFTERNOON AND
EVENING.

THE WIND ADVISORY WILL REMAIN IN EFFECT TIL 4 AM PST MONDAY. A FLASH
FLOOD WATCH REMAINS IN EFFECT THROUGH LATE TONIGHT. AN URBAN AND
SMALL STREAM FLOOD ADVISORY WAS RECENTLY ISSUED FOR PORTIONS OF THE
BAY AREA TIL 3 AM PST MONDAY.

&&

.PREV DISCUSSION...AS OF 3:00 PM PST SUNDAY...AS EXPECTED WIDESPREAD
RAIN OVERNIGHT SWITCHED TO SCATTERED SHOWERS ACROSS OUR CWA. DID
GET A REPORT FROM THE CITY OF NAPA LATE THIS MORNING OF BRIEF
HEAVY RAIN AND SMALL HAIL. THAT WILL LIKELY BE THE MAIN STORY THIS
EVENING INTO THE OVERNIGHT HOURS AS ANOTHER COLD FRONT RIPS
THROUGH OUR AREA. UNLIKE THE STORM THAT BROUGHT WIDESPREAD
SUBSTANTIAL RAINFALL TO OUR AREA, THIS ONE WILL LIKELY BRING A
SHORTER DURATION OF HEAVY RAIN. SINCE MANY LOCAL STREAMS AND
CREEKS RAPIDLY RESPONDED YESTERDAY AND HAVE BEEN SLOW TO DROP,
ANY HEAVY RAINFALL COULD LEAD TO MORE FLASH FLOODING.

MODELS ARE IN VERY GOOD AGREEMENT WITH THE OVERALL SCOPE AND
TIMING OF THE RAIN. LOOKS LIKE THE MAIN BAND WILL MOVE INTO THE
NORTH BAY AROUND 5 PM, TO SF BAY AREA BETWEEN 8 AND 11 PM, SILICON
VALLEY TO MONTEREY BAY 11 PM TO 1 AM. DURING THOSE TIMES RAIN
RATES WILL RAPIDLY ESCALATE ALONG WITH GUSTY WINDS. AHEAD OF THE
FRONT SOUTHERLY WINDS OF 15 TO 25 MPH WITH GUSTS OVER 35 MPH CAN
BE EXPECTED. IN LIGHT OF ALL OF THE RAIN YESTERDAY, THESE VALUES
MAY BE ENOUGH TO TOPPLE TREES.

IMMEDIATELY BEHIND THE FRONT VERY UNSTABLE AIR (FOR OUR REGION)
WILL QUICKLY MOVE IN. CAPE VALUES NEAR 1300 J/KG (WITH ZERO CIN)
AND LIFTED VALUES NEAR MINUS 4 ARE DEPICTED OVER SAN
FRANCISCO AROUND 1 AM. THIS WILL LEAD TO A FAVORABLE CONVECTIVE
ENVIRONMENT WITH SHOWERS AND THUNDERSTORMS FORECAST. SMALL HAIL
WILL ALSO BE VERY LIKELY WHICH COULD LEAD TO SLICK ROADWAYS FOR
THE MORNING HOURS. THE MAIN UPPER LEVEL LOW AND TROF AXIS DO NOT
PUSH THROUGH UNTIL LATE IN THE MORNING, SO SHOWERS AND
THUNDERSTORMS ARE A GOOD BET THROUGH THE MORNING RUSH POSSIBLY
THROUGH THE ENTIRE MORNING.

RAINFALL TOTALS FOR MOST LOCATIONS BY TOMORROW MORNING WILL BE
LESS THAN THE STORM YESTERDAY WITH MOST URBAN SPOTS FORECAST TO BE
IN THE 2/3" TO 1 1/3" RANGE WITH COASTAL RANGES MOSTLY BETWEEN
1.5" AND 3". AGAIN, PLEASE KEEP IN MIND THAT THE BULK OF THE RAIN
IS FORECAST TO FALL DURING A SHORT DURATION ON ALREADY WET SOILS,
SO EVEN THOUGH THE NUMBERS ARE NOT THAT LARGE WE ARE VERY
CONCERNED ABOUT HYDRO ISSUES.

DRIER WEATHER WILL RETURN LATER ON MONDAY AS A RIDGE OF HIGH
PRESSURE REBUILDS BACK INTO OUR REGION. OUTSIDE OF SOME LIGHT
RAIN FOR TUESDAY EVENING INTO WEDNESDAY MORNING, WE WILL HAVE A
CHANCE TO DRY OUT.

MODELS CONTINUE TO SHOW A RETURN TO WET WEATHER EITHER NEXT
THURSDAY OR FRIDAY AS ANOTHER ATMOSPHERIC RIVER TAKES AIM ON OUR
REGION.

&&

.AVIATION...AS OF 10:00 PM PST SUNDAY...FRONTAL SYSTEM IS NEARING
THE SFO BAY AREA AND WIND SHIFT TO THE SOUTHWEST IS EXPECTED AFTER
08Z. LIGHTNING HAS BEEN DETECTED OVER THE COASTAL WATERS
AND THERE COULD BE A THUNDERSTORM CONTAINING MODERATE TO HEAVY
RAIN IN THE SFO/OAK VICINITY THROUGH 12Z. SHOWERS CONTINUE INTO
MONDAY MORNING AS THE LOW PRESSURE SYSTEM MOVES INTO NORTHERN
CALIFORNIA. BREEZY NORTHWEST WINDS DEVELOP MONDAY AFTERNOON.

VICINITY OF KSFO...CIGS HAVE REMAINED IN THE VFR RANGE BUT MAY
DROP BRIEFLY INTO MVFR RANGE AS THE FRONT MOVES THROUGH. LIGHT TO
MODERATE RAIN WITH A POSSIBLE THUNDERSTORM IN THE VICINITY
THROUGH 12Z. SOUTH WINDS 15-20 KT WITH GUSTS 30-35 KT SWITCHING
TO SOUTHWEST AND DECREASING AFTER 08Z. QUESTION IS HOW MUCH OF A
WESTERLY COMPONENT THE WIND DIRECTION WILL HAVE AFTER 08Z.
FORECAST IS FOR A SWITCH TO 230 DEGREES BUT CONFIDENCE IS NOT HIGH
AND MAY ONLY GRADUALLY SWITCH TO 210-220 FOR A COUPLE HOURS BEFORE
GOING TO 230-240. SHOWERS WITH RISING CIGS AFTER 12Z.

SFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...VFR WITH CIGS REMAINING ABOVE 3000
FEET. LIGHT RAIN BECOMING SHOWERY AFTER 13Z.

&&

.BEACHES...AS OF 04:17 AM PST SUNDAY...A HIGH SURF ADVISORY
REMAINS IN EFFECT THROUGH TUESDAY MORNING. LATEST BUOY REPORTS 11
TO 13 FT WITH A PERIOD OF 13/14 SEC. WESTERLY SWELL WILL BUILD
THROUGH THE DAY AND IS STILL EXPECT TO PEAK TONIGHT THROUGH EARLY
MONDAY. MOST COASTAL LOCATION REMAIN SOLIDLY IN THE HIGH SURF ADV
CRITERIA...BUT LATEST MODELS SUGGEST A FEW SPOT NORTH OF THE
GOLDEN GATE WILL BE BORDERLINE HIGH SURF WARNING. SINCE IT IS
BORDERLINE...WILL LEAVE THE ADV AS IS FOR NOW. EITHER
WAY...CONDITIONS ALONG THE COAST WILL BECOME RATHER ROUGH LATER
TODAY THROUGH TUESDAY MORNING.

&&

.MARINE...AS OF 3:00 PM PST SUNDAY...WINDS WILL INCREASE LATER
THIS AFTERNOON AS ANOTHER STORM SYSTEM MOVES THROUGH THE REGION.
GUSTY NORTHERLY FLOW WILL DEVELOP BEHIND THE STORM SYSTEM ON
MONDAY. WESTERLY SWELLS WILL INCREASE SUNDAY AND SUNDAY NIGHT
PEAKING ON MONDAY BEFORE SUBSIDING TUESDAY. THE COMBINATION OF
GUSTY WINDS AND BUILDING SWELL WILL PRODUCE HAZARDOUS CONDITIONS.
MARINERS ARE URGED TO USE CAUTION.
