AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
200 PM PDT WED APR 17 2013

.SYNOPSIS...
A HIGH PRESSURE RIDGE ALOFT BUILDING ALONG THE WEST COAST...AND AT
THE SURFACE OVER NEVADA...WILL PRODUCE WEAK TO MODERATE STRENGTH
SANTA ANA CONDITIONS THROUGH FRIDAY. MUCH WARMER TEMPERATURES
THURSDAY AND FRIDAY WEST OF THE MOUNTAINS. A FIRE WEATHER WATCH IS
IN EFFECT. THE MARINE LAYER IS EXPECTED TO REDEVELOP OVER THE
WEEKEND...HELPING TO MODERATE TEMPERATURES ALONG THE COAST AND
INLAND VALLEYS.

&&

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

WINDS ALREADY VEERING AROUND TO NORTHEAST AS HIGH PRESSURE RIDGE
ALOFT BUILDS ALONG WEST COAST AND AT THE SURFACE OVER NORTHERN
NEVADA. BY THURSDAY MORNING OFFSHORE PRESSURE GRADIENTS INCREASE TO
AT LEAST 12 MB BETWEEN NE NEVADA AND SW CALIFORNIA COAST...AND
850-700 MB WINDS ARE MINIMUM OF 30 KT. PRESSURE GRADIENT TEMPORARILY
DIMINISHED TO AROUND 4 MB THURSDAY AFTERNON THEN INCREASE BACK TO 10
MB FRIDAY MORNING...THE CORE OF THE STRONGEST 850-700 MB WINDS
SHIFTS TO OVER SAN DIEGO COUNTY. THE 12Z WRF WAS ABOUT 5 TO 10 MPH
LOWER THAT THE 06Z WRF...CALLING INTO QUESTION THE HIGH WIND WATCH.
WILL LET THE NEXT SHIFT TAKE A LOOK AT THE 18Z GUIDANCE AND MAKE
CALL ON DOWNGRADING TO ADVISORY OR UPGRADING TO WARNING. MOS
GUIDANCE SHOWING SIGNIFICANTLY WARMER TEMPERATURES WEST OF THE
MOUNTAINS...HAVE ADJUSTED TEMPERATURE FORECAST GRIDS CLOSE TO BUT
NOT AS QUITE AS HIGH AS THOSE NUMBERS.

FRIDAY EVENING BEGINS TRANSITION BACK TO ONSHORE FLOW. CURRENT
FORECAST LOOKS GOOD.

EXCERPTS FROM EARLY MORNING FORECAST DISCUSSION FOLLOW...THIS WILL
HELP THE MARINE LAYER TO REDEVELOP AND THE COASTAL CLOUDS TO RETURN.
IT IS TOUGH TO SAY WHETHER WE GET THEM SATURDAY MORNING OR SATURDAY
NIGHT. RIGHT NOW THE FORECAST IS FOR SATURDAY NIGHT SINCE SO MUCH
DRY AIR WILL STILL BE IN PLACE FRIDAY NIGHT. THIS TRANSITION WILL
START A COOLING TREND WEST OF THE MOUNTAINS THIS WEEKEND WHILE THE
MOUNTAIN AND DESERT TEMPS PEAK. SOMETIME NEXT WEEK A VERY WEAK AND
CUTOFF LOW PRESSURE CIRCULATION WILL DAMPEN THE RIDGE OF HIGH
PRESSURE. A FEW RECENT MODEL RUNS INDICATE SOME LIGHT PRECIP IS
POSSIBLE...BUT MOST GUIDANCE DOES NOT. ANOTHER POSSIBLE FEATURE IS A
SHORTWAVE TROUGH MOVING THROUGH THE INTERIOR WEST ON MONDAY. BEHIND
IT SOME COLD AIR IN THE ROCKIES WILL GENERATE OFFSHORE FLOW SO THAT
TUESDAY AND WEDNESDAY COULD HAVE SOME OFFSHORE WINDS AGAIN. THAT
WOULD FLUSH OUT THE COASTAL CLOUDS...BUT THIS TIME OF YEAR YOUR BETS
ARE ON THE MARINE LAYER...AND OUR FORECAST REFLECTS THE MARINE LAYER
THINKING FOR NOW.

&&

.FIRE WEATHER...
THE 12Z HI RESOLUTION MODEL RUNS WERE LOWER ON WIND SPEEDS/GUSTS
THAN THE 06Z RUN. USED FORECASTER DISCRETION AND CHOSE NOT TO
UPGRADE THE FIRE WEATHER WATCH AT THIS TIME. IF THIS TREND CONTINUES
IN THE 18Z AND/OR THE 00Z HI RES RUNS THEN WILL DROP THE WATCH. IF
NOT...THEN WILL UPGRADE TO A RED FLAG WARNING EVEN THOUGH LEAD TIME
WILL BE GREATLY REDUCED.

RELATIVE HUMIDITY ALREADY DROPPING RAPIDLY...TEMPS ARE UP 10
DEGREES AND DEWPOINTS DOWN 25 DEGREES. LOOKING FOR POOR TO NO
RECOVERY TONIGHT...AND TEMPS ANOTHER 10 TO 15 DEGREES WARMER
THURSDAY WITH RH BELOW 10 PERCENT. WINDS ALREADY SHIFTING TO
NORTHEAST AND STILL FORECASTING HIGHEST WINDS MID TO LATE THURSDAY
MORNING. A SLOW DECREASE IN WINDS THURSDAY AFTERNOON THROUGH FRIDAY
BUT STILL STRONG ENOUGH TO PRODUCE GUSTS OVER 35 MPH. MARINE LAYER
DEPTH INCREASES TO 750 FEET FRIDAY EVENING...AND 1500 FEET SATURDAY
AND SUNDAY. ELSEWHERE STILL VERY DRY WITH GENERAL WINDS EAST TO
NORTHEAST BUT SUSTAINED WINDS FORECAST TO BE LESS THAN 10 MPH WITH
WIND GUSTS GENERALLY LESS THAN 20 MPH.

&&

.AVIATION...
172011Z...UNRESTRICTED VIS AND SKC THROUGH THURSDAY MORNING...EXCEPT
BLOWING DUST MAY LOCALLY REDUCE VIS TO AOB 3SM AFTER 18/0900 UTC
OVER AND W/SW OF MTNS AND IN THE COACHELLA VALLEY. THROUGH 18/0900
UTC...N WIND GUSTS OF 25-40 KT WILL BRING MOD UDDFS OVER AND S/SW OF
THE MTNS. AFTER 18/0900 UTC...NE TO E WIND GUSTS OF 35-50 KT WILL
CREATE MOD-STG UDDFS/ROTORS/LLWS OVER AND W/SW OF MTNS. KSNA AND
KONT LIKELY TO HAVE LLWS BEFORE STRONGER WINDS SURFACE...ALTHOUGH
WINDS MAY NOT SURFACE AT KSNA UNTIL AFTER 18/1800 UTC.
MEANWHILE...KONT SHOULD GET NE SURFACE GUSTS IN THE 20-25 KT RANGE
BY 18/1500 UTC. KSAN AND KCRQ WILL NOT GET ANY SIGNIFICANT EASTERLY
SURFACE WINDS...BUT MAY GET LLWS IN THE 18/1200-1700 UTC
TIME-FRAME.

&&

NORTHWEST WINDS SHOULD PICK UP AGAIN BY LATE THIS AFTERNOON...AS
WIND GUSTS INCREASE TO AROUND 25 KNOTS OVER THE OUTER WATERS.
