AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT THU NOV 1 2007

.SYNOPSIS...FAIR WEATHER IS EXPECTED TODAY AS HIGH PRESSURE BUILDS
ACROSS THE REGION. WEAK ONSHORE FLOW AND A SHALLOW MARINE LAYER WILL
BRING LOW CLOUDS AND FOG TO THE COASTAL AREAS TONIGHT AND FRIDAY
MORNING. OFFSHORE FLOW WILL DEVELOP FRIDAY NIGHT AND SATURDAY AND
BRING LOCALLY GUSTY WINDS THROUGH PASSES AND CANYONS...LOW
HUMIDITIES AND WARMER WEATHER. THE WINDS WILL DIMINISH BY
SUNDAY...AND DRY FAIR WEATHER WILL DOMINATE EARLY NEXT WEEK.

&&

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

A DEEPER MARINE LAYER THIS MORNING ALLOWED THE CLOUDS TO GET INTO
PARTS OF THE INLAND VALLEYS THIS MORNING...BUT THE DAY WILL BE FAIR
AFTER THE BURNOFF. AN UPPER RIDGE WILL CONTINUE TO AMPLIFY ALONG THE
WEST COAST...BUT WITH A WEAK HANGBACK TROUGH OVER SOCAL. THE
BUILDING HIGH WILL SQUASH THE MARINE LAYER A BIT FOR TONIGHT AND FRI
MORNING SO THE CLOUDS AND FOG WILL BE LESS EXTENSIVE. OFFSHORE
PRESSURE GRADIENTS START TO FORM FRI AND REACH MAXIMUM STEEPNESS SAT
MORNING. THESE GRADIENTS ALONE WILL PRODUCE DRY BREEZY WINDS
ESPECIALLY IN THE FAVORED LOCATIONS LIKE THROUGH AND BELOW MOUNTAIN
PASSES AND CANYONS. THIS COMPONENT WILL BE THE ONLY DRIVING FORCE
SINCE THE FLOW ALOFT IS VERY WEAK AND THERE IS LITTLE OR NO THERMAL
GRADIENT TO HELP PUSH THE WINDS. THE DRY AIR IS THE REASON FOR THE
FIRE WEATHER WATCH AND NOT THE WINDS SINCE THEY WILL NOT BE VERY
STRONG...WIDESPREAD OR LONG LASTING...EXCEPT IN A COUPLE ISOLATED
LOCATIONS. THE WEST COAST UPPER RIDGE AND OFFSHORE FLOW WILL
DOMINATE THE WEATHER AT LEAST THROUGH NEXT WED...BUT WITH BRIEF WEAK
ONSHORE FLOW DURING THE AFTERNOONS. THIS WILL ENSURE FAIR DRY
WEATHER AND TEMPS A LITTLE ABOVE NORMAL.

&&

.AVIATION...
011415Z...BASED ON THE 12Z NKX SOUNDING AND EARLY MORNING MDCRS
SOUNDINGS THE MARINE LAYER DEPTH WAS AROUND 1700 FEET MSL. STRATUS
WITH BASES AROUND 1200 FEET MSL SHOULD CLEAR TO THE COAST BETWEEN
16Z AND 18Z THIS MORNING. STRATUS SHOULD PUSH BACK ONTO THE COAST BY
SUNSET AND INLAND DURING THE EVENING REACHING THE INLAND VALLEY
AREAS BY MIDNIGHT. STRATUS IS NOT EXPECTED TO REACH THE KONT AREA
TONIGHT BUT SOME RADIATION FOG COULD DEVELOP IN THE
VICINITY...ESPECIALLY AROUND KCNO. A LITTLE EARLIER CLEARING IS
EXPECTED FRIDAY MORNING.

ABOVE THE MARINE LAYER...VFR CONDITIONS WITH A MOSTLY CLEAR SKY AND
UNRESTRICTED VISIBILITIES SHOULD CONTINUE THROUGH FRIDAY.

FOR SATURDAY...A DEVELOPING OFFSHORE FLOW SHOULD BRING SOME GUSTY
NORTHEAST WINDS THROUGH AND BELOW MOUNTAIN PASSES AND CANYONS WITH
ASSOCIATED UP AND DOWN DRAFTS AND LOW LEVEL WIND SHEAR...ESPECIALLY
IN THE VICINITY OF KONT.

&&

.SGX WATCHES/WARNINGS/ADVISORIES...

FIRE WEATHER WATCH FOR LATE FRIDAY NIGHT THROUGH SUNDAY IN THE
MOUNTAINS AND VALLEYS...SEE LAXRFWSGX.

RIP CURRENT POTENTIAL...HIGH. VERY STRONG CURRENTS AND DANGEROUS
SWIMMING CONDITIONS ARE EXPECTED...SEE LAXSRFSGX.
