AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
937 AM PST WED FEB 17 2016
.SYNOPSIS...
RAIN AND MOUNTAIN SNOW WILL FALL ACROSS THE REGION THROUGH
TOMORROW MORNING AND WINDS WILL BE GUSTY IN THE MOUNTAINS AND
THROUGH PASSES AND CANYONS. TEMPERATURES WILL BE NEAR NORMAL
THROUGH TOMORROW THEN WARM FIFTEEN TO TWENTY DEGREES BY SUNDAY AND
REMAIN ABOVE NORMAL INTO NEXT WEEK.
&&
.SHORT TERM...(TDY-FRI)
INITIAL BAND OF MOISTURE HAS ARRIVED THOUGH SO FAR CLOUDS HAVE
BEEN BASED OVER 10K FT AND WE'VE ONLY SEEN A FEW SPRINKLES
REPORTED ACROSS SBA/SLO COUNTIES. BLENDED PW PRODUCT FROM THE GOES
SHOWS PW'S IN THE 1.3-1.4" RANGE ABOUT 400 NM SOUTHWEST OF PT
CONCEPTION WHICH IS ABOUT .2" BELOW WHAT THE MODELS WERE SHOWING
FOR THIS TIME SO IT'S POSSIBLE MODELS ARE SLIGHTLY OVERESTIMATING
THE AMOUNT OF MOISTURE THAT'S GETTING ENTRAINED. 12Z NAM AND GFS
BOTH INDICATED A NARROW BAND OF PRECIP DEVELOPING THIS AFTERNOON
ACROSS THE WESTERN CHANNEL ISLANDS INTO SBA AND VENTURA COUNTIES,
HOWEVER THE MORE RECENT HRRR/RAP SOLUTIONS ARE FURTHER WEST AND
LIGHTER AT LEAST THROUGH LATE AFTERNOON. BUT BOTH THOSE EVENTUALLY
SHOW THE HIGHER RAINFALL RATES DEVELOPING DURING THE EVENING AND
SPREADING EAST INTO VENTURA AND EVENTUALLY LA COUNTY LATER ON. SO
AMOUNTS STILL LOOK ON TRACK BUT TIMING STILL A BIT UNCERTAIN.
IT WILL BE WINDY UP IN THE MOUNTAINS AND ANTELOPE VALLEY TONIGHT
AND CAN'T RULE OUT SOME MOUNTAIN WAVE ACTIVITY. MOST AREAS LIKELY
WILL BE IN THE ADVISORY CRITERIA BUT SOME ISOLATED WARNING LEVEL
WINDS ARE POSSIBLE.
***FROM PREVIOUS DISCUSSION***
LATE THIS AFTERNOON OR EARLY THIS EVENING THE WEAK FRONT WILL
BEGIN TO MOVE ACROSS SLO COUNTY AND WILL BRING RAIN TO ALL AREAS
THERE. THIS EVENING AND OVERNIGHT THE FRONT WILL PHASE INTO THE
ENERGY AND SUBTROPICAL MOISTURE PLUME OVER SBA COUNTY AND SWEEP IT
TO THE EAST. AT THIS POINT EASTERN SBA COUNTY AND MOST OF VENTURA
COUNTY WILL BE UNDER THE GUN AND CAN EXPECT SOME MODERATE RAIN ESP
OVER THE COASTAL SLOPES. THE SYSTEM WILL THEN WEAKEN AND MOVE
INTO L.A. COUNTY WHERE ALMOST ALL AREAS WILL SEE RAIN JUST NOT AS
MUCH AS SBA/VTA COUNTY. AS WITH THE OTHER COUNTIES THE SOUTH
FACING COASTAL SLOPES WILL SEE THE BEST RAINFALL AND HIGHEST
RAINFALL RATES.
THIS WILL BE A WARM NON CONVECTIVE STORM SO DO NOT SEE ANY TSTMS
FORMING. SNOW LEVELS WILL ALSO BE VERY HIGH ABOVE 7000 FEET AND DO
NOT SEE MUCH OF ANY WINTER WEATHER PROBLEMS WITH THIS
SYSTEM...PERHAPS 2 TO 4 INCHES OF SNOW AT THE RESORT LEVELS.
WIND WILL BE THE OTHER ISSUE WITH THIS SYSTEM...ESP OVERNIGHT WHEN
A 140 KT SOUTHERLY JET PASSES OVER THE AREA. GOOD SOUTHERLY FLOW
AHEAD OF THE FRONT WILL BRING ADVISORY LEVEL WIND GUSTS AROUND 45
MPH TO THE INTERIOR OF SLO AND SBA COUNTIES THIS MORNING AND THEN
TO THE MTNS (INCLUDING THE SANTA MONICAS) OF VTA AND LA COUNTIES AND
THE ANTELOPE VLY THIS AFTERNOON. THE ANTELOPE VLY WILL BE VERY
SUSCEPTIBLE TO MTN WAVE ACTIVITY DUE TO THE PERPENDICULAR WIND
FLOW OVER THE SAN GABRIELS. WIND GUSTS TO 60 OR 65 MPH ARE
POSSIBLE OVER THE MTNS AND ANTELOPE VLY THIS EVENING AND OVERNIGHT
AND A HIGH WIND WATCH IS OUT TO COVER THIS POSSIBILITY. THE DAY
SHIFT WILL EVALUATE THE 12Z MDLS AND DECIDE IF A HIGH WIND WARNING
IS NEEDED.
RAINFALL AMOUNTS FOR THIS SYSTEM HAVE BEEN REVISED UPWARDS BASED
ON THE ADDITIONAL ENERGY AND MOISTURE NOW FCST TO IMPINGE ONTO
THE AREA. RAINFALL AMOUNTS FOR SBA/VTA COUNTIES WILL BE AROUND A
HALF INCH ON THE FLAT AREAS AND AND INCH TO AN INCH AND A HALF
(AND ISOLATED 2 INCH AMOUNTS) ACROSS THE COASTAL SLOPES. SLO AND
LA COUNTIES WILL SEE A QUARTER TO A HALF INCH OF RAIN WITH LOCAL 1
INCH AMOUNTS ON THE COASTAL SLOPES. IF THIS SYSTEM CONTINUES TO
GROW FASTER THAN PREDICTIONS IT COULD EVEN PRODUCE SOME MORE RAIN
THAN THE CURRENT FCST AND FOR SURE WILL NEED CLOSE WATCHING TODAY.
THE FRONT SHOULD BE OVER L.A. COUNTY THURSDAY MORNING JUST IN TIME
TO MAKE THE COMMUTE UNFUN. THERE SHOULD NOT BE TOO MUCH IN THE
WAY OF POST FRONTAL SHOWERS OVER SLO/SBA/VTA COUNTIES. BY MID OR
LATE MORNING THE FRONT WILL EXIT LA COUNTY AND THE CHC OF RAIN
WILL SHRINK TO ZERO DURING THE AFTERNOON WITH CLEARING SKIES
ABOVE.
FRIDAY WILL BE SUNNY DRY AND COOL IN THE WAKE OF THE FRONT.
.LONG TERM...(SAT-TUE)
MILD CONDITIONS CONTINUE INTO SATURDAY AS A WEAK SYSTEM MOVES INTO
NRN CALIFORNIA. THE STRONG RIDGE OF HIGH PRESSURE IS EXPECTED TO
RETURN STARTING SUNDAY AND PEAKING IN STRENGTH MONDAY. DURING THIS
TIME MODERATE OFFSHORE GRADIENTS WILL BE RETURNING WITH SOME
LOCALLY GUSTY SANTA ANA WINDS IN THE USUAL PLACES. HIGHS SUNDAY
EXPECTED TO CLIMB INTO THE LOWER 80S FOR THE WARMER AREAS AND
POSSIBLY CLOSE TO 90 MONDAY AND TUESDAY. THIS EVENT DOESN'T APPEAR
TO BE QUITE AS HOT OR AS LONG LASTING AS THIS RECENT HEAT WAVE
BUT STILL ABOUT 20 DEGRESS ABOVE NORMAL MOST COAST/VALLEY AREAS.
