AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT THU SEP 26 2013

.SYNOPSIS...
THE LOW PRESSURE TROUGH WILL CONTINUE TO MOVE THROUGH THE GREAT
BASIN TODAY. THIS WILL RESULT IN MODERATE TO STRONG WESTERLY WINDS
IN THE MOUNTAINS AND DESERTS AND BELOW NORMAL TEMPERATURES ACROSS
ALL OF SOUTHERN CALIFORNIA. THE DEEP MARINE LAYER WILL BRING
ISOLATED SHOWERS FROM THE COAST TO THE MOUNTAINS...AND LOCALLY DENSE
FOG IN THE MOUNTAINS THIS MORNING. WINDS WILL TURN NORTHEASTERLY
LATE TONIGHT AND EARLY FRIDAY AS WEAK HIGH PRESSURE BUILDS EAST
ACROSS NEVADA...WITH LOCALLY GUSTS WINDS THROUGH AND BELOW PASSES
AND CANYONS. THE OFFSHORE FLOW WILL BRING DRYING AND MUCH WARMER
WEATHER THROUGH THE WEEKEND...WITH AREAS OF GUSTY EASTERLY WINDS
SATURDAY.

&&

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

TROUGH CONTINUES OVER THE WEST...WITH THE TROUGH AXIS OVER WESTERN
NEVADA INTO THE SIERRA. THE TROUGH WILL CONTINUE TO MOVE
EAST...THOUGH WITH WEST WINDS OF 40 TO 50 KNOTS ABOVE THE
INVERSION...BETWEEN 4500 AND 5500 FEET MSL...AND THE MOUNTAIN
WAVE...SOME GUSTY WINDS WILL CONTINUE IN THE DESERTS AND MOUNTAIN
DESERT SLOPES...SO THE WIND ADVISORY HAS BEEN CONTINUED UNTIL 5 PM
FOR THE RIVERSIDE/SAN DIEGO COUNTY MTNS/DESERTS. AREAS OF BLOWING
DUST WILL BE POSSIBLE AGAIN TODAY IN THE DESERTS. WINDS LOOK JUST
LOW ENOUGH FOR SW SAN BERNARDINO COUNTY TO KEEP THEM BELOW WIND
ADVISORY CRITERIA.

AFTER THE TROUGH OF LOW PRESSURE MOVES EAST...WE WILL BE IN NORTH
FLOW ALOFT TONIGHT/SATURDAY...WITH NE FLOW AT 850 MB DEVELOPING BY
AROUND 2 AM FRI. THERE IS SOME COLD AIR ADVECTION AT 700 MB BUT LESS
AT 850 MB...AND BUFKIT SOUNDINGS FOR THE LOCAL WRF SHOW A WEAK
INVERSION AROUND 650 MB...SO THERE IS A CHANCE OF A MTN WAVE...BUT
THE MTN WAVE SHOULD NOT BE STRONG ENOUGH TO BRING ANY SIGNIFICANT
WINDS TO THE VALLEY FLOORS UNTIL AFTER SUNRISE. BEST TIMES FOR
WINDS...BASED ON 12Z NAM 1.3-KM FIRE WEATHER NEST...WILL BE 8 AM TO
NOON...AND MOSTLY IN THE SANTA ANA MTNS...INLAND EMPIRE AND NORTHERN
PARTS OF THE COACHELLA VALLEY. A WIND ADVISORY WILL BE LIKELY ISSUED
FOR MAINLY FRIDAY MORNING FOR THOSE AREAS WITH THE AFTERNOON
PACKAGE. WINDS WILL INCREASE AGAIN FRIDAY NIGHT/SATURDAY...BUT
MAINLY THROUGH E-W PASSES/CANYONS...SO SAN DIEGO COUNTY WOULD BE
MORE AFFECTED. TEMPS WILL INCREASE SUBSTANTIALLY...ESPECIALLY IN THE
VALLEYS...FRIDAY AND SATURDAY...WITH QUITE A FEW 90S IN THE VALLEYS
BY SATURDAY.

WEST FLOW ALOFT WILL PREVAIL STARTING SUNDAY AS A TROUGH APPROACHES
THE PAC NW. THIS WILL END THE OFFSHORE FLOW SUNDAY...THOUGH THE
MARINE LAYER APPEARS NOT TO DEVELOP YET. TEMPS WILL NOT CHANGE MUCH
SUNDAY...THEN A COOLING TREND WILL START MONDAY AS HEIGHTS LOWER DUE
TO THE TROUGH TO THE NORTH. ANOTHER TROUGH WILL BRING MORE COOLING
AND PROBABLY A DEEPER MARINE LAYER AROUND WED...WITH OFFSHORE FLOW
AGAIN POSSIBLE AROUND THU AFTER THE TROUGH PASSES BY AND A RIDGE
FORMS OFF THE COAST.

&&

.AVIATION...
261620Z...THROUGH 270400 UTC...BKN-SCT CLOUDS WITH MULTIPLE LAYERS
BETWEEN 2500 FT MSL AND 9000 FT MSL. MTNS OCNL OBSCD. FRZLVL NEAR

MOGR UDDFS OVER AND TO THE SW OF MTNS...IMPACTING APPROACHES TO MOST
AIRPORTS WITH MOGR UDDFS AND/OR LLWS.

&&

.MARINE...
WELL DEFINED SURFACE TO 5000 FT DEEP LOW PRESSURE SYSTEM HAS BEEN
MOVING SE 5 KT ACROSS INNER WATERS OVERNIGHT/THIS MORNING. CURRENTLY
CENTERED ABOUT 25NM DUE W OF CARDIFF BY THE SEA. ESTIMATING CENTRAL
PRES OF 1006 MB. COMBINED SEAS AROUND 6 FT BEING OBSERVED AHEAD OF
THE LOW AND +9 FT BEHIND THE LOW. MOST OF THIS IS COMING FROM WIND
WAVE CONTRIBUTION AND AVERAGE PERIOD IS LESS THAN 8 SECONDS...SO
SMALL CRAFT WILL BE GETTING A LOT OF SLAMMING AND SURF CONDITIONS
WILL BE CONFUSED AND VERY CHOPPY THROUGH THIS EVENING. CURRENTLY
TIMING ON SMALL CRAFT ADVISORY LOOKS GOOD...ENDING AT MIDNIGHT. SEA
STATE SHOULD BECOME LUMPY BUT SMOOTHER OVERNIGHT AS WINDS FALL OFF
AND CLEAN UP CONSIDERABLY FRIDAY MORNING WITH OFFSHORE FLOW AROUND
5-10 KT AND A WNW SWELL OF 5 FT AT 9 SECONDS. THIS RESIDUAL WNW
SWELL WILL DROP QUICKLY...FALLING TO LESS THAN 3 FT BY FRIDAY
EVENING. OFFSHORE WINDS WILL BE ABOUT TWICE AS STRONG SATURDAY
MORNING AND COULD HAVE SOME GUSTS AROUND 20 KT ABEAM OF RIVER
MOUTHS.

.FIRE WEATHER...
GUSTY WESTERLY WINDS WILL CONTINUE IN THE MOUNTAINS AND DESERTS
TODAY...WITH HIGHEST GUSTS NEAR SAN GORGONIO PASS AND THE SAN DIEGO
COUNTY DESERT FOOTHILLS. RH SHOULD BE ABOVE AVERAGE WEST OF THE
MOUNTAIN CRESTS WITH A MARINE LAYER DEPTH NEAR 5500 FEET MSL...AND
LOCALLY BELOW 20 PERCENT IN THE DESERTS.

FRIDAY THROUGH THE WEEKEND...OFFSHORE FLOW WILL DEVELOP AND BRING A
MUCH DRIER AIRMASS ALONG WITH GUSTY NORTHEAST TO EAST WINDS THROUGH

MOUNTAINS AND ALONG THE COASTAL FOOTHILLS WILL BE MAINLY IN THE
20-30 MPH RANGE...WITH LOCAL GUSTS OF 45 MPH POSSIBLE IN FAVORED
AREAS BELOW THE CAJON PASS...THROUGH THE SANTA ANA CANYONS...AND SAN
DIEGO COUNTY MOUNTAINS. DAY-TIME HUMIDITY WILL BE IN THE TEENS FOR
MOST INLAND AREAS...PARTICULARLY THE INLAND EMPIRE...AND THEN FALL
INTO THE UPPER SINGLE DIGITS IN MANY AREAS ON SATURDAY...EXCEPT NEAR
THE COAST. ONLY POOR TO MODERATE OVERNIGHT RECOVERY EXPECTED. WHILE
DURATIONS OF THE COMBINATION OF LOW HUMIDITY AND WIND DO NOT LOOK
SUFFICIENT FOR A RED FLAG WARNING FOR FRIDAY...WE ARE CONSIDERING A
FIRE WEATHER WATCH FOR SATURDAY IN SAN DIEGO COUNTY VALLEYS/DESERTS
AS THE EASTERLY GRADIENT WILL FOCUS WINDS THERE WITH AREAS OF
SUSTAINED WINDS 25 MPH POSSIBLE...AND THERE WILL BE LONG DURATIONS
OF RH BELOW 15 PERCENT.
