AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
826 AM PDT SAT MAY 30 2015

.SYNOPSIS...HIGH PRESSURE ALOFT WILL BRING ANOTHER VERY WARM DAY
INLAND...WHILE A SHALLOW MARINE LAYER KEEPS COOLER...MARINE
AIR ALONG THE COAST. AREAS OF LOW CLOUDS AND FOG WILL DECREASE THIS
MORNING...THEN RETURN AND GRADUALLY SPREAD FARTHER INLAND THROUGH
WEDNESDAY AS THE RIDGE MOVES EAST AND A LOW PRESSURE TROUGH
DEVELOPS OVER THE WEST. INCREASING ONSHORE FLOW ASSOCIATED WITH
THE TROUGH WILL MEAN GUSTY WESTERLY WINDS AGAIN OVER THE MOUNTAINS
AND DESERTS BY LATE MONDAY. TEMPERATURES WILL BE NEAR...TO A BIT
BELOW AVERAGE MOST OF NEXT WEEK.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

FORECAST WAS UPDATED TO INCREASE MAX TEMPS INLAND TODAY.

MARINE STRATUS WAS EXTENSIVE OVER THE CA COASTAL WATERS EARLY THIS
MORNING AND EXTENDED INTO THE WESTERN VALLEYS. THE 12Z MIRAMAR
SOUNDING INDICATED THE LAYER WAS FAIRLY SHALLOW THOUGH AND TOPPED BY
A STRONG 12 DEGREE C INVERSION BASED NEAR 1200 FT MSL. THIS WAS
ABOUT 700 FT LOWER THAN FRI MORNING. WINDS WERE LIGHT AT ALL
REPORTING SITES.

THE SHALLOWER MARINE LAYER AND DECREASED CLOUD DEPTH WILL ALLOW FOR
A FAST BURN OFF OF THE LOW CLOUDS AND FOG INLAND THIS MORNING. SOME
CLOUDS AND FOG ARE LIKELY TO LINGER INTO THE AFTERNOON CLOSER TO
THE COAST HOWEVER...DUE TO THE STRONG INVERSION. IT WILL BE A VERY
WARM AFTERNOON WELL INLAND WITH TEMPERATURES CLIMBING INTO THE
90S...AND REACHING 102 TO 105 IN THE LOWER DESERTS. SLIGHTLY COOLER
ON SUNDAY AS ONSHORE FLOW INCREASES AND THE MARINE LAYER BEGINS TO
DEEPEN.

FROM PREVIOUS DISCUSSION...

TODAY AND SUNDAY WILL BE THE WARMEST DAYS WITH TEMPERATURES
TOPPING OUT INLAND IN THE MID TO UPPER 90S IN THE HIGH DESERT AND
103-105 IN THE LOWER DESERTS...AS THE UPPER RIDGE MAXIMIZES AND
EVENTUALLY MOVES INTO THE FOUR CORNERS REGION ON SUNDAY. A FAST
MOVING UPPER LEVEL SHORTWAVE...THE FIRST IN A LIKELY PROGRESSION
OF ADDITIONAL WAVES LATER IN THE WEEK...WILL MOVE ACROSS SOCAL ON
MONDAY. THIS FEATURE WILL BRING A MUCH MORE PRONOUNCED MARINE
LAYER AND INLAND INTRUSION OF MARINE AIR AND LOW CLOUDS.

ON TUESDAY...BEHIND THE SHORTWAVE A HEALTHY ONSHORE FLOW WILL
CONTINUE AS UPPER LEVEL FLOW BECOMES ZONAL. ANOTHER SHORTWAVE BUT
WEAKER WILL PASS THROUGH WEDNESDAY...KEEPING OUR REGION IN AN
ONSHORE DOMINANT PATTERN WITH TEMPERATURES NEAR TO SLIGHTLY BELOW
NORMAL.

PRESSURE GRADIENTS WILL BE PRETTY HEALTHY MONDAY AND TUESDAY AND
WESTERLY WINDS WILL BECOME GUSTY WITH THE STRONGEST WINDS LIKELY
TUESDAY THROUGH THE MOUNTAIN PASSES AND INTO THE DESERTS. GUSTS OF
50 TO 60 MPH WILL BE POSSIBLE AND MAY REACH WIND ADVISORY CRITERIA
IN THE MORE WIND PRONE LOCATIONS OF THE MOUNTAINS AND DESERTS.

SOME BETTER RUN TO RUN CONTINUITY WITH A POSSIBLE STRONGER LOW
MOVING THROUGH CALIFORNIA THURSDAY THROUGH FRIDAY. THE ECM IS THE
STRONGEST SOLUTION WITH THIS FEATURE AND COULD BRING SOME COASTAL
DRIZZLE ALONG WITH COOLER TEMPERATURES AND GUSTY WINDS.

.AVIATION...
301530Z...LOW CLOUDS...WITH BASES FROM 1000 TO 1300 FT MSL AND TOPS
NEAR 1700 FT MSL WILL CONTINUE OVER THE COASTAL AREAS THIS MORNING.
AREAS OF FOG WITH VIS 1-3SM WHERE CLOUDS INTERSECT HIGHER TERRAIN.
LOW CLOUDS WILL CLEAR TOWARDS THE COAST BETWEEN 17Z AND 19Z THIS
MORNING. PATCHY LOW CLOUDS WILL LIKELY REMAIN AT THE BEACHES THROUGH
THE AFTERNOON. LOW CLOUDS WILL LIKELY BEGIN SPREADING INLAND AFT 03Z

MARINE STRATUS BURNED OFF BY MID MORNING MOST LAND AREAS...BUT
REMAINED OVER SOME BEACH AREAS AND OVER THE COASTAL WATERS INTO THE
EARLY AFTERNOON. WINDS WERE LIGHT...BUT A FEW OF THE WIND-PRONE
CORRIDORS INTO THE DESERTS HAD GUSTS AROUND 25 MPH.

IT WILL BE WARMER THIS WEEKEND...BUT MAINLY INLAND...WHILE THE
COASTAL AREAS EXPERIENCE TYPICAL SPRING WEATHER. THIS SHOULD BE
WELCOME FOR THE MARATHON SUN MORNING WITH MORNING CLOUDS AND

TEMPERATURES MORE MODERATE. AS THE INVERSION STRENGTHENS...CLEARING
MAY BE ONLY PARTIAL ALONG THE IMMEDIATE COAST EACH AFTERNOON...BUT
MOST AREAS SHOULD SEE AT LEAST A FEW HOURS OF SUN EACH DAY. THE
WARMEST DAY IS EXPECTED TO BE SAT...WITH SOME COOLING SUN...AND
BETTER COOLING NEXT WEEK AS THE RIDGE MOVES EAST AND A TROUGH MOVES

A FEW DEGREES NEXT WEEK AS THE ONSHORE FLOW AND MARINE LAYER RAMP

.SYNOPSIS...HIGH PRESSURE ALOFT WILL PREVAIL THROUGH SATURDAY
AND BRING A WARMING TREND WITH NIGHT AND MORNING LOW CLOUDS AND
FOG REMAINING MUCH CLOSER TO THE COAST THAN EARLIER THIS WEEK.
DENSE FOG WILL BE POSSIBLE DURING SOME OF THE LATE NIGHTS AND
EARLY MORNINGS THROUGH SATURDAY. A TROUGH OF LOW PRESSURE WILL
MOVE THROUGH THE WEST COAST EARLY NEXT WEEK AND BRING COOLING WITH
A DEEPER MARINE LAYER AND INCREASING WEST WINDS IN THE MOUNTAINS
AND DESERTS...BUT OVERALL...TEMPERATURES WILL BE NEAR SEASONAL
NORMALS NEXT WEEK AND WITH VERY LITTLE OR NO RAINFALL.

WELL THE MARINE LAYER IS INDEED QUITE A BIT SHALLOWER THIS
MORNING. THIS IS EVIDENT ON THE 00Z SOUNDING AND THE LIMITED
EXTENT OF LOW STRATUS CLOUDS THIS MORNING...MAINLY ALONG THE COAST
AND ABOUT 10 TO 15 MILES INLAND.

THE UPPER LEVEL RIDGE AXIS WILL BEGIN TO MOVE EAST INTO CALIFORNIA
TODAY. THE WARMEST AIRMASS ALOFT WILL SPREAD ACROSS THE STATE ON
SATURDAY AND WITH VERY LITTLE MODIFICATION TO THE AIRMASS...INLAND
TEMPERATURES WILL REMAIN QUITE WARM FOR SUNDAY TOO. TEMPERATURES
THEN WILL BE THE HOTTEST IN THE DESERTS WITH MID TO UPPER 90S IN
THE HIGH DESERT AND UP TO 105 IN THE LOWER DESERTS.

AN UPPER CLOSED LOW WILL SWEEP INTO THE PAC NW MONDAY THROUGH
TUESDAY AND SWING A WEAK UPPER LEVEL TROUGH ACROSS CALIFORNIA IN
THE PROCESS. THIS FEATURE WILL BRING A GRADUAL COOLDOWN TO ALL
AREAS. GUSTY ONSHORE WINDS WILL BE LIKELY WITH THE MOST WIND PRONE
AREAS GUSTING UP TO 50 MPH AT TIMES MONDAY AND TUESDAY.

FOR WEDNESDAY THROUGH THE END OF NEXT WEEK THE SYNOPTIC FLOW WILL
BE QUITE STRONG ZONAL ONSHORE AND SOME IMPULSES MOVING THROUGH
THE MEAN FLOW AT TIMES KEEPING WINDS OCCASIONALLY GUSTY THROUGH
AND BELOW THE FAVORED ONSHORE PASSES. TEMPERATURES DURING THIS
TIMEFRAME WILL BE NEAR NORMAL TO SLIGHTLY BELOW NORMAL.

&&

.AVIATION...

290900Z...LOW CLOUDS WILL CONTINUE TO SPREAD INLAND THIS MORNING
INTO WESTERN PARTS OF THE INLAND VALLEYS. BASES WILL BE AROUND 1200
FEET MSL WITH TOPS REACHING TO 2000 FEET AND VIS BELOW 5SM ALONG
INLAND EDGE OF CLOUDS BETWEEN THOSE ELEVATIONS. SCATTER OUT WILL
OCCUR BY 18-19Z...BUT SOME BEACHES MAY NOT CLEAR COMPLETELY OR FOR
VERY LONG. LOW CLOUDS WILL PUSH ASHORE AFTER 03Z WITH BASES SLIGHTLY
LOWER AT AROUND 1000 FEET MSL AND NOT GOING QUITE AS FAR INLAND
OVERNIGHT. ABOVE AND BEYOND THE MARINE LAYER...MOSTLY CLEAR AND VFR
CONDITIONS TODAY AND TONIGHT.

GOOD AFTERNOON CLEARING OCCURRED TODAY...AND IT WAS WARMER IN MOST
AREAS. SAN DIEGO LINDBERGH FIELD REACHED 71...WHICH IS THE FIRST
TIME THAT PLACE RECORDED A TEMPERATURE ABOVE 70 SINCE MAY 11.
LIKEWISE...ONTARIO AIRPORT REACHED 85...THE FIRST TIME THEY HAVE
BEEN ABOVE 80 SINCE MAY 11. THE WARMING TREND SHOULD CONTINUE FRIDAY
DUE TO THE WARMING ALOFT UNDER THE RIDGE...AND MOST LIKELY WE WILL
THEN BE ABLE TO SAY THAT PALM SPRINGS AIRPORT WILL HAVE HAD ITS
FIRST 100 DEGREE TEMP SINCE MAY 2.

REGARDING THE MARINE LAYER...THE INVERSION BASE IS NOW AROUND 1400-
1500 FT MSL...DOWN OVER 500 FT FROM 24 HOURS AGO. THIS WILL RESULT
IN LESS EXTENSIVE STRATUS IN THE VALLEYS THAN ON PREVIOUS
NIGHTS...BUT SOME LOCAL DENSE FOG WILL BE POSSIBLE. WE PROBABLY WILL
NOT HAVE ANY FOG MAKING IT WEST TO THE COASTAL MESAS TONIGHT OR
EARLY FRIDAY...BUT THE MARINE LAYER COULD POTENTIALLY GET SHALLOW
ENOUGH FRIDAY NIGHT FOR LOW VISIBILITIES ON SOME MESAS THEN BASED ON
WRF AND NAM4 SOUNDINGS. WITH HIGHEST PRESSURE HEIGHTS AND TEMPS
ALOFT SATURDAY...THAT SHOULD BE OUR WARMEST DAY...WITH SOME LOWER
DESERT LOCATIONS REACHING 105 AND VERY WARMEST INLAND EMPIRE
LOCATIONS REACHING 95. THE UPPER TROUGH MOVING INTO THE WEST COAST
SUNDAY/SUNDAY NIGHT WILL HAVE MOST OF ITS EFFECTS TO OUR NORTH SINCE
HEIGHT FALLS WILL BE MINOR HERE...BUT ONSHORE FLOW SHOULD INCREASE
AND CONTRIBUTE TO SOME COOLING AND A DEEPER MARINE LAYER.

ENSEMBLE MODEL OUTPUT IS SHOWING MEAN TROUGHING OVER THE WEST COAST
FOR THE MIDDLE AND LATTER PARTS OF NEXT WEEK...BUT WITH MOST OF THE
LOWER HEIGHTS FURTHER NORTH INSTEAD OF THE SOUTHERLY CLOSED-LOW
SCENARIOS WE HAVE HAD A LOT OF IN MAY. THUS...TEMPS WILL PROBABLY BE
NEAR OR JUST SLIGHTLY BELOW NORMAL MID/LATE NEXT WEEK...AND COASTAL
STRATUS WILL LIKELY BE FAIRLY EXTENSIVE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
310 AM PDT THU MAY 28 2015

.SYNOPSIS... A RIDGE OF HIGH PRESSURE WILL BRING A MORE SHALLOW
MARINE LAYER AND WARMER WEATHER THROUGH THIS WEEKEND. NIGHT AND
MORNING LOW CLOUDS WILL CONTINUE BUT WILL BE MORE RESTRICTED TO
THE COASTAL AREAS. A TROUGH OF LOW PRESSURE WILL MOVE THROUGH THE
WEST COAST EARLY NEXT WEEK AND BRING A COOLING TREND AND MORE
WIDESPREAD LOW CLOUDS. OTHER THAN A CHANCE OF COASTAL DRIZZLE THIS
MORNING...NO PRECIPITATION IS EXPECTED THROUGH THE MIDDLE OF NEXT
WEEK.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

WIDESPREAD MARINE STRATUS CONTINUES EARLY THIS MORNING ALONG THE
COAST AND THROUGH THE WESTERN VALLEYS. THE MARINE INVERSION WILL
GRADUALLY SHRINK THOUGH THIS WEEKEND AS AN UPPER LEVEL RIDGE OF
HIGH PRESSURE PEAKING AT ABOUT 588 DM PUSHES INTO CALIFORNIA.
TEMPERATURES WILL CLIMB THROUGH THE WEEKEND EVERYWHERE...WITH THE
MOST PRONOUNCED WARMING INLAND. TEMPERATURES IN THE HIGH DESERT
WILL PEAK IN THE MID TO UPPER 90S...AND IN THE LOWER DESERTS
BETWEEN 100 TO 105 FRIDAY THROUGH SUNDAY.

THE HEAT WILL BE SHORT LIVED HOWEVER AS WELCOME RELIEF ARRIVES
MONDAY THROUGH TUESDAY NEXT WEEK DUE TO A PASSING UPPER LEVEL
TROUGH ASSOCIATED WITH A PACNW LOW PRESSURE SYSTEM. ONSHORE
GRADIENTS WILL PICK UP EARLY NEXT WEEK AS WELL WITH GUSTY WINDS
LIKELY THROUGH THE ONSHORE FAVORED PASSES AND CANYONS AND COASTAL
SLOPES. TEMPERATURES WILL RETURN TO NEAR NORMAL LEVELS FOR MID
NEXT WEEK AS ZONAL UPPER LEVEL FLOW BECOMES WELL ESTABLISHED. NO
SIGNIFICANT WEATHER MAKERS ARE EXPECTED AT THIS TIME THROUGH LATE
NEXT WEEK...ALTHOUGH OCCASIONALLY GUSTY DIURNALLY DRIVEN WINDS
WILL BE LIKELY.

CLOUDS. SCATTER OUT IS EXPECTED BY 18-19Z. LOWER CLOUDS WITH BASES
AROUND 1000 FEET MSL WILL RETURN AFTER 02Z THIS EVENING AND SPREAD
NOT AS FAR INLAND OVERNIGHT. OTHERWISE...MOSTLY CLEAR AND VFR
CONDITIONS ARE EXPECTED TODAY AND TONIGHT.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

SKIES WERE MOSTLY CLEAR AT MID-EVENING EXCEPT FOR AREAS OF LOW
CLOUDS IN COASTAL AND VALLEY AREAS OF SAN DIEGO COUNTY. AFTER A
COUPLE DARK DREARY DAYS...WE HAD GOOD CLEARING ALONG THE COAST THIS
AFTERNOON WITH JUST SOME STRATUS LINGERING WITHIN A FEW MILES OF THE
SAN DIEGO COUNTY COAST. LOCAL WRF SHOWS STRATUS MOVING INTO MOST
COASTAL AND VALLEY LOCATIONS...THOUGH THE LATEST AIRCRAFT SOUNDINGS
AT LINDBERGH FIELD SHOW THE MARINE INVERSION BASE DOWN TO ABOUT 2000
FT MSL. REGARDING THE DRIZZLE IN THE FORECAST FOR MAINLY WESTERN SAN
DIEGO COUNTY...LOOKS LIKE THAT WILL BE RATHER ISOLATED AS THE CLOUD
DEPTH WILL BE ONLY A LITTLE OVER 1000 FEET DEEP. LOOK FOR EARLIER
CLEARING THURSDAY AS THERE WILL BE LESS EXTENSIVE CLOUD COVER TO
BEGIN WITH...AND LOCAL WRF SHOWS WARMING BELOW THE INVERSION TO
COUNTERBALANCE THAT ABOVE...SO THE INVERSION WILL NOT GET TOO
STRONG. STILL...LOCAL STRATUS COULD LINGER NEAR THE BEACHES IN THE
AFTERNOON.

WITH THE HIGH PRESSURE ALOFT...WE SHOULD HAVE TEMPERATURES
INCREASING THE NEXT FEW DAYS...WITH VALLEY...MOUNTAIN AND DESERT
LOCATIONS WARMING TO ABOUT 5 DEGREES ABOVE NORMAL BY FRIDAY. THE
RIDGE AXIS WILL MOVE THROUGH SATURDAY...SO THAT SHOULD BE THE
WARMEST DAY INLAND. DESPITE A TROUGH MOVING FROM THE NE PACIFIC TO
THE WEST COAST SUNDAY/SUNDAY NIGHT...THE HEIGHTS DO NOT FAR MUCH
HERE DUE TO THE RIDGE BEING A SHORT DISTANCE TO THE SOUTHEAST AND
MOST OF THE ENERGY WITH THE TROUGH BEING TO OUR NORTH. THUS...THE
COOLING TREND EARLY NEXT WEEK WILL BE RATHER SLIGHT. AFTER ABOUT
NEXT TUESDAY...MODELS AND ENSEMBLES ARE RATHER DIVERGENT WITH THEIR
SOLUTIONS REGARDING PLACEMENT OF THE MODERATE RIDGES AND
TROUGHS...BUT IN THE ABSENCE OF ANY STRONG RIDGE OR TROUGH IN EARLY
JUNE...SEASONAL TEMPS WITH NIGHT/MORNING STRATUS NEAR THE COAST IS
THE BEST BET FOR THE MIDDLE OF NEXT WEEK. THERE IS SOME INDICATION
THAT THE EAST-WEST RIDGING TYPICAL IN JUNE IS GOING TO DEVELOP AND
PERSIST OVER NORTHWEST MEXICO THOUGH SO THAT SHOULD BRING MORE
CONSISTENT SUMMER-LIKE WEATHER TO THE MOUNTAINS/DESERTS OF SOUTHERN
CALIFORNIA NEXT WEEK.
