AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
900 PM PDT TUE SEP 30 2014
.SYNOPSIS...
LOW CLOUDS AND FOG WILL DEVELOP OVER THE COASTAL AREAS TONIGHT. DRY 
NORTHWEST FLOW ALOFT AND WEAK ONSHORE FLOW WILL MAINTAIN FAIR AND 
SEASONAL WEATHER WEDNESDAY. FOR THURSDAY INTO SUNDAY...HIGH PRESSURE 
ALOFT AND WEAK TO LOCALLY MODERATE OFFSHORE FLOW WILL BRING MUCH 
HOTTER AND DRIER DAYS WITH LOCALLY GUSTY NORTHEAST WINDS. SLOW 
COOLING MAY DEVELOP NEAR THE BEACHES ON SUNDAY...THEN SPREAD INLAND 
EARLY NEXT WEEK AS THE RIDGE WEAKENS AND ONSHORE FLOW RETURNS.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
PATCHY LOW CLOUDS HAVE BEGUN TO DEVELOP ALONG THE COAST THIS 
EVENING. WIND OBS ARE SHOWING SOME INDICATION OF A WEAK COASTAL EDDY 
SPINNING UP JUST AS HI-RES MODELS PREDICTED...SO FORECAST LOOKS ON 
TRACK FOR MORE WIDESPREAD LOW CLOUDS IN THE COASTAL AREAS AND 
WESTERN VALLEYS TONIGHT. 
THE WARMING TREND CONTINUES WEDNESDAY AS AN UPPER LEVEL RIDGE OF 
HIGH PRESSURE BEGINS TO BUILD OVER THE EASTERN PACIFIC. COLD AIR 
FILTERING INTO THE GREAT BASIN AND BUILDING SURFACE HIGH PRESSURE 
BEHIND A SHORT-WAVE TROUGH WILL GENERATE SOME LOCAL GUSTY OFFSHORE 
WINDS BY LATE WEDNESDAY MORNING...MAINLY BELOW THE CAJON PASS. 
OFFSHORE FLOW WILL LIKELY NOT BE STRONG ENOUGH TO SCOUR OUT THE 
MARINE LAYER...SO EXPECT LOW CLOUDS AND FOG TO RETURN TO THE COAST 
WEDNESDAY EVENING. NORTHEAST TO EAST WINDS WILL PICK UP WEDNESDAY 
NIGHT...WITH LOW CLOUDS GRADUALLY BEING PUSHED OFF THE COAST. AS 
THIS HAPPENS THE MARINE LAYER WILL BECOME MORE SHALLOW...LEADING TO 
THE POTENTIAL FOR DENSE FOG BEFORE CLOUDS COMPLETELY CLEAR OUT 
THURSDAY MORNING. OFFSHORE SURFACE PRESSURE GRADIENTS WILL PEAK 
THURSDAY MORNING AT AROUND -10 MB SAN-TPH. WIND GUSTS DURING THE 
PEAK WILL BE AROUND 35-45 MPH IN THE WIND PRONE PASSES AND CANYONS 
IN THE INLAND EMPIRE AND ORANGE COUNTY...AS WELL AS ON THE FAVORED 
COASTAL MOUNTAIN SLOPES AND FOOTHILLS IN SAN DIEGO COUNTY. WINDS 
WILL WEAKEN DURING THE AFTERNOON...PICKING UP THU EVENING WITH A 
SECOND WEAKER PEAK FRI MORNING. MUCH WEAKER OFFSHORE FLOW IS 
EXPECTED FOR SATURDAY.
ALONG WITH THE OFFSHORE FLOW...THE UPPER LEVEL RIDGE OF HIGH 
PRESSURE WILL MOVE OVERHEAD AND STRENGTHEN THROUGH FRIDAY. THIS 
COMBINATION WILL LEAD TO HOT AND VERY DRY CONDITIONS. BY FRIDAY HIGH 
TEMPERATURES WILL BE 10-20 DEGREES ABOVE NORMAL. ALTHOUGH THE HIGH 
BEGINS TO WEAKEN SOME ON SATURDAY...AREAS WEST OF THE MOUNTAINS WILL 
CONTINUE TO WARM DUE TO THE WEAK OFFSHORE FLOW. WIDESPREAD TEMPS IN 
THE MID 90S TO LOW 100S LIKELY WEST OF THE MOUNTAINS 
SATURDAY...EXCEPT AT THE BEACHES WHERE HIGHS WILL GENERALLY BE IN 
THE 80S. MINOR COOLING WILL OCCUR SUNDAY AS THE HIGH CONTINUES TO 
WEAKEN AND PRESSURE GRADIENTS TREND MORE ONSHORE...WITH THE MOST 
NOTABLE COOLING ALONG THE COAST. GRADUAL COOLING CONTINUES INTO THE 
MIDDLE OF NEXT WEEK AS THE RIDGE BREAKS DOWN AND ONSHORE FLOW 
STRENGTHENS. LOW CLOUDS AND FOG MAY RETURN TO THE COASTAL AREAS BY 
TUESDAY MORNING.
&&
.AVIATION...
010300Z...COAST/VALLEYS...A FEW PATCHES OF LOW CLOUDS ARE BEGINNING 
TO DEVELOP ALONG THE COAST. CLOUDS WILL CONTINUE TO DEVELOP...WITH 
CIGS AT THE COASTAL AIRPORTS BY 01/05-08Z. MOST CIGS WILL BE 
700-1000 FT MSL WITH TOPS TO 1200 FT MSL. LOCAL VIS BELOW 3 MI IN 
FOG COULD OCCUR ALONG COASTAL MESAS AND OTHER HIGHER COASTAL TERRAIN 
BETWEEN 08Z AND 16Z WED...WITH A SMALL CHANCE OF VIS BELOW 1 MI. 
MOST AREAS SHOULD CLEAR BY 17Z WED. LOW CLOUDS WILL RETURN TO THE 
COAST EARLIER WEDNESDAY EVENING...BETWEEN 02/03-06Z.
MOUNTAINS/DESERTS...CLEAR WITH UNRESTRICTED VIS THROUGH WED EVENING.
&&
.MARINE...
800 PM...NO HAZARDOUS MARINE WEATHER IS EXPECTED THROUGH SUNDAY.
&&
.FIRE WEATHER...FROM PREVIOUS DISCUSSION...
HIGH PRESSURE ALOFT AND OFFSHORE FLOW WITH LOCALLY GUSTY NORTHEAST 
WINDS WILL BRING MUCH WARMER AND DRIER CONDITIONS FOR THURSDAY 
THROUGH SUNDAY. STRONGEST WINDS...WITH LOCAL GUSTS TO AROUND 40 
MPH...ARE EXPECTED FOR LATE WEDNESDAY NIGHT INTO THURSDAY 
MORNING...FOLLOWED BY GRADUAL WEAKENING FRIDAY AND SATURDAY. FRIDAY 
AND SATURDAY WILL BE THE WARMEST DAYS...ESPECIALLY INLAND WHERE 
TEMPERATURES OF 95 TO 105 DEGREES ARE POSSIBLE. SLOW COOLING MAY 
BEGIN NEAR THE COAST ON SUNDAY AS THE OFFSHORE PRESSURE GRADIENTS 
CONTINUE TO WEAKEN. HUMIDITIES WILL FALL THURSDAY...REACHING THE MID 
TEENS BY MID MORNING. EXPECT LOWEST DAYTIME HUMIDITIES OF 5 TO 10 
PERCENT FOR INLAND AREAS FRIDAY AND SATURDAY WITH POOR OVERNIGHT 
RECOVERY. HUMIDITIES ARE EXPECTED TO SLOWLY RECOVER FOR SUNDAY INTO 
EARLY NEXT WEEK AS WEAK ONSHORE FLOW RETURNS. WHILE RED FLAG WARNING 
CRITERIA MAY NOT BE MET DURING THIS PERIOD...THERE WILL STILL BE AN 
ELEVATED THREAT FOR WILDFIRES FOR THURSDAY INTO SUNDAY.
