AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
150 PM PDT FRI JUN 28 2013
.SYNOPSIS...
A VERY STRONG RIDGE OF HIGH PRESSURE WILL BUILD OVER THE FOUR
CORNERS AND GREAT BASIN THROUGH THIS WEEKEND...BRINGING VERY HOT
WEATHER TO THE INLAND AREAS THROUGH AT LEAST MONDAY. EVEN THE COAST
WILL SEE SOME WARMING ON SATURDAY...AS THE MARINE LAYER WILL BE
TEMPORARILY DISRUPTED. HOWEVER...THE EDDY AND MARINE LAYER WILL
RETURN FOR SUNDAY AND MONDAY...COOLING COASTAL AREAS ONCE AGAIN.
THIS RIDGE WILL GRADUALLY SHIFT NORTHWARD...AS AN UPPER LEVEL TROUGH
SETS UP ALONG THE COAST. THIS SHOULD HELP DEEPEN THE MARINE LAYER
AND STRENGTHEN THE ONSHORE FLOW ACROSS THE REGION...BRINGING SOME
COOLER CONDITIONS TO THE REGION...ESPECIALLY WEST OF THE MOUNTAINS
LATER NEXT WEEK.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
.SHORT TERM (TONIGHT THROUGH MONDAY)...
WATER VAPOR IMAGERY CONTINUES TO SHOW A STRONG RIDGE OF HIGH
PRESSURE CENTERED OVER THE FOUR CORNERS AREA THIS AFTERNOON...WITH
SUNNY SKIES ACROSS THE REGION. AS A RESULT...TEMPERATURES THIS
AFTERNOON ARE PRIMARILY RUNNING 3 TO 6 DEGREES WARMER THAN THIS TIME
YESTERDAY.
THIS IS ONLY THE START OF THE REAL HEAT...AS TEMPERATURES SPIKE THIS
WEEKEND. MODELS ARE SUGGESTING THAT 850 MB TEMPERATURES WILL WARM
TO BETWEEN 30 AND 33 FOR BOTH SATURDAY AND SUNDAY...WITH LITTLE
CHANGE HONESTLY INTO MONDAY. THEREFORE...BELIEVE THAT THE NEXT
THREE DAYS WILL LIKELY BE VERY HOT FOR MOST OF THE INLAND
AREAS...WITH ONLY MINOR FLUCTUATIONS POSSIBLE. THE MOST NOTICEABLE
DIFFERENCE WILL REALLY BE WITH THE WARM OVERNIGHT TEMPERATURES. IN
FACT...SOME OF THE LOWER DESERTS WILL LIKELY SEE TEMPERATURES ONLY
FALLING INTO THE 90S...BEFORE RAPIDLY HEATING DURING THE DAY.
HOWEVER...SATURDAY APPEARS TO BE THE HOTTEST DAY FOR THE COASTAL
AREAS...AS SOME DRIER AIR MOVES INTO THE REGION AND MAY HELP MIX OUT
THE MARINE LAYER. THIS WILL LIKELY OCCUR THOUGH AFTER A VERY FOGGY
START ON SATURDAY MORNING. IN FACT...A RELATIVELY PERSISTENT AND
SHALLOW MARINE LAYER IS CURRENTLY LINGERING OVER THE COASTAL WATERS
AND ALONG THE BEACHES THIS AFTERNOON...WHICH IS HELPING TO MODERATE
TEMPERATURES ALONG THE COAST. THIS MARINE LAYER WILL MOVE BACK
INLAND LATER THIS EVENING...BRINGING DENSE FOG TO THE IMMEDIATE
COAST AND AREAS WITHIN ABOUT 8 MILES OF THE COAST. THEREFORE...HAVE
ISSUED A DENSE FOR THE COAST LATE TONIGHT. ALSO EXTENDED THE
EXCESSIVE HEAT THROUGH MONDAY...AS THE INLAND AREAS CONTINUE TO
ROAST. SEVERAL RECORDS ARE FORECAST TO FALL AT THIS TIME OVER THE
NEXT THREE DAYS...SO THIS HEATWAVE IS UNPRECEDENTED FOR THIS TIME OF
YEAR...EVEN THOUGH IT IS NORMALLY HOT. GUSTY WEST WINDS WILL ALSO
DEVELOP THROUGH AND BELOW THE FAVORED CANYONS AND PASSES OF THE
MOUNTAINS AND DESERTS THE NEXT FEW AFTERNOON AND EVENINGS.
&&
.EXTENDED (TUESDAY THROUGH FRIDAY)...
THE HIGH PRESSURE RIDGE OVER CENTRAL NEVADA WILL BEGIN TO ELONGATE
AND SHIFT NORTHEASTWARD ON TUESDAY. TEMPERATURES OVER THE MOUNTAINS
AND DESERTS ARE FORECAST TO COOL BY AROUND 5 TO 10 DEGREES...THOUGH
STILL WELL ABOVE AVERAGE FOR THIS TIME OF YEAR. THE RIDGE WILL
GRADUALLY CONTINUE TO ERODE AND WEAKEN THROUGH THE FOURTH OF
JULY...AS A TROUGH OF LOW PRESSURE SINKS SOUTHWARD ALONG THE WEST
COAST. THIS SHOULD HELP TO DEEPEN THE MARINE LAYER AND STRENGTHEN
THE ONSHORE FLOW ACROSS THE REGION...BRINGING SOME COOLER
CONDITIONS...ESPECIALLY WEST OF THE MOUNTAINS.

STRATUS/FOG GRADUALLY FILLING IN 5 TO NEAR 10 SM INLAND. TIMING OF
LOW STRATUS/FOG ARRIVAL FOR COASTAL AIRPORTS IS LOW CONFIDENCE. BEST
ESTIMATE CURRENTLY IS 29/0500-0700 UTC FOR KSAN AND KCRQ AND
29/0400-0600 UTC FOR KSNA. SLIGHT CHANCE THAT FOG MAY ARRIVE EARLIER
THAN THAT. FOG MAY BE DENSE AT KCRQ AND KSNA...AND POSSIBLY KSAN AS
WELL. CONFIDENCE NOT HIGH ENOUGH TO PUT INTO KSAN TAF AT THE MOMENT.
LOW STRATUS/FOG SHOULD CLEAR OUT 29/1500-1700 UTC.
MTNS/DESERTS...WESTERLY WIND GUSTS TO 35-40 KT WILL BE LIKELY OVER
MTN RIDGES AND DESERT MTN SLOPES LATE THIS AFTERNOON AND

.MARINE...
A SOUTHERLY SWELL GENERATED BY FORMER TROPICAL CYCLONE COSME WILL
BRING SURF AS HIGH OF 4 TO 6 FEET WITH HIGHER SETS POSSIBLE ALONG
FAVORED BEACHES TODAY...WITH SURF LOWERING TO 3 TO 5 FEET SATURDAY.
THE ELEVATED SURF AND SWELL WILL BRING STRONG RIP CURRENTS TO ORANGE
AND SAN DIEGO COUNTY BEACHES...AND SO THE BEACH HAZARDS STATEMENT
CONTINUES THROUGH SATURDAY EVENING. THE SWELL WILL CONTINUE TO LOWER
SUNDAY THROUGH EARLY NEXT WEEK. NO OTHER SIGNIFICANT SWELLS ARE ON
THE HORIZON.
AREAS OF DENSE FOG ARE LIKELY TONIGHT THROUGH EARLY TOMORROW MORNING
OVER THE COASTAL WATERS...WITH PATCHY DENSE FOG AGAIN SATURDAY
NIGHT/SUNDAY MORNING.

.FIRE WEATHER...
VERY HOT AND DRY CONDITIONS WILL CONTINUE TO PREVAIL ACROSS THE
MOUNTAINS...DESERTS...AND INLAND EMPIRE THIS WEEKEND. TEMPERATURES
WILL SOAR INTO THE TRIPLE DIGITS...WITH SOME RECORDS POSSIBLE.
DAYTIME HUMIDITY VALUES WILL ALSO FALL BELOW 15 PERCENT FOR THESE
AREAS...WITH SINGLE DIGIT HUMIDITIES POSSIBLE IN THE DESERTS. POOR
TO MODERATE RECOVERIES WILL BECOME MORE WIDESPREAD THIS WEEKEND AS
WELL. THE EXCESSIVE HEAT AND VERY DRY CONDITIONS WILL ELEVATE THE
FIRE DANGER. HOWEVER...SOME GUSTY WEST WINDS MAY ALSO DEVELOP NEAR
AND BELOW THE PASSES AND DESERT SLOPES OF MAINLY RIVERSIDE AND SAN
DIEGO COUNTIES...WITH GUSTS UP TO 40 MPH POSSIBLE FOR SEVERAL HOURS
LATE EACH AFTERNOON. THEREFORE...THESE AREAS MAY BE EVEN MORE
SUSCEPTIBLE TO FIRE DEVELOPMENT OR GROWTH.
