AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PST SAT NOV 14 2009

.SYNOPSIS...COOL DRY NORTHWEST FLOW TODAY. WARMER SUNDAY THROUGH
TUESDAY UNDER HIGH PRESSURE. MODERATE OFFSHORE FLOW WILL CAUSE LOCAL
GUSTY WINDS THROUGH AND BELOW MOUNTAIN CANYONS AND PASSES SUNDAY AND
MONDAY. COOLER WITH MORE CLOUDS DURING THE SECOND HALF OF NEXT WEEK
AS A COUPLE OF UPPER LEVEL LOW PRESSURE SYSTEMS MOVE THROUGH.

&&

.DISCUSSION...FOR SOUTHWEST CALIFORNIA INCLUDING SAN DIEGO...
ORANGE...SOUTHWEST SAN BERNARDINO AND WEST RIVERSIDE COUNTIES.

.SHORT TERM (TODAY-MONDAY)...THERE WERE PATCHY LOW CLOUDS AND FOG
BACKED UP AGAINST THE MOUNTAINS THIS MORNING...OTHERWISE IT WAS
MOSTLY CLEAR. THE 12Z KNKX SOUNDING SHOWED A FAIRLY MOIST BOUNDARY
LAYER AND MODERATE WESTERLY WINDS ALOFT. ONSHORE GRADIENTS TO THE E
WITH ABOUT 3 MB SAN-IPL.

DECREASING RESIDUAL LOW LEVEL MOISTURE WILL BRING PARTLY CLOUDY
SKIES TODAY....CLEARING OUT BY LATE THIS AFTERNOON IN DRY COOL NW
FLOW. MAX TEMPERATURES WILL BE ABOUT 5-10 DEGREES BELOW SEASONAL
AVERAGES IN MOST AREAS. AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL
MOVE ACROSS THE WEST SUNDAY AND MONDAY AS AN UPPER LOW MOVES OVER
THE COLORADO PLATEAU. A 1035 MB SURFACE HIGH WILL BUILD OVER
NORTHERN NEVADA ON SUNDAY...THEN SLOWLY WEAKEN AND MOVE EAST ON
MONDAY. THIS WILL CAUSE WEAK TO LOCALLY MODERATE OFFSHORE FLOW WITH
LOCAL GUSTY WINDS THROUGH AND BELOW MOUNTAIN CANYONS AND PASSES
SUNDAY AND MONDAY. MODEL FORECAST THERMAL/PRESSURE GRADIENTS BETWEEN
THE VALLEYS AND DESERTS INDICATE THAT WIND GUSTS COULD GET CLOSE TO
ADVISORY STRENGTH DESPITE THE LACK OF UPPER LEVEL SUPPORT. ISOLATED
GUSTS TO NEAR 50 MPH ARE POSSIBLE IN THE WINDIEST LOCATIONS. THE
GUSTY WINDS ARE EXPECTED TO FIRST DEVELOP IN THE NORTHERN AREAS
EARLY SUNDAY MORNING...THEN IN THE SAN DIEGO INLAND VALLEYS AND
MOUNTAINS BY MID DAY. THE WINDS WILL WEAKEN SUNDAY EVENING...THEN
INCREASE AGAIN MONDAY MORNING. THE COMBINATION OF OFFSHORE FLOW AND
UPPER LEVEL HIGH PRESSURE WILL CAUSE AN INCREASE IN TEMPS AND A
DECREASE IN HUMIDITY. HIGH TEMPS INLAND WILL BE ABOUT 5 DEGREES
ABOVE SEASONAL AVERAGES BY MONDAY WITH 80S EXPECTED IN THE WARMEST
VALLEYS. THE WARM...DRY OFFSHORE WINDS WILL INCREASE THE FIRE
WEATHER HAZARD SUNDAY AND MONDAY.

&&

.LONG TERM (TUESDAY-FRIDAY)...MUCH WEAKER WINDS AND CONTINUED WARM
ON TUESDAY WITH RIDGING ALOFT AND WEAKENING OFFSHORE FLOW. AN UPPER
TROUGH SHOULD MOVE THROUGH LATE WEDNESDAY AND ANOTHER EARLY FRIDAY.
THESE WILL BRING MORE CLOUDS AND COOLING WITH LOCAL GUSTY ONSHORE
WINDS AT TIMES IN THE MOUNTAINS AND DESERTS. MOST OF THE COLD AIR
AND ENERGY ASSOCIATED WITH THESE TROUGHS WILL MOVE PAST TO THE N AND
MOISTURE WILL BE LIMITED. SO WILL ONLY INDICATE LOW LEVEL POPS FOR
NOW...NOT ENOUGH TO PRODUCE PRECIP IN THE ZONES.

&&

.FIRE WEATHER...SURFACE HIGH PRESSURE WILL BUILD OVER THE PLATEAU
AND BRING WARM DRY OFFSHORE FLOW TO SOUTHERN CALIFORNIA SUNDAY AND
MONDAY. THERE WILL BE LOCALLY GUSTY WINDS 25 TO 35 MPH WITH ISOLATED
GUSTS TO NEAR 50 MPH AND MUCH LOWER HUMIDITIES THAT WILL BRING
CRITICAL FIRE WEATHER CONDITIONS. A FIRE WEATHER WATCH IS IN EFFECT
FOR THE MOUNTAINS...VALLEYS AND INLAND ORANGE COUNTY FOR SUNDAY AND
MONDAY.
