AREA FORECAST DISCUSSION

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...

WIDESPREAD RECORD HIGH TEMPERATURES ARE POSSIBLE TODAY. TEMPERATURES
WILL REMAIN ABOVE NORMAL INTO THE WEEKEND BUT WILL BEGIN TO EASE
TOMORROW AS OFFSHORE FLOW DIMINISHES.

&&

.SHORT TERM...(TODAY-FRI)

TEMPERATURES ARE A FEW DEGREES WARMER TODAY ACROSS THE REGION AND
MANY COASTAL SITES ARE WARMER THAN THE INLAND VALLEYS. WINDS
DIMINISHED A LITTLE SOONER THAN EXPECTED AND THE ADVISORIES HAVE
BEEN CANCELLED... HOWEVER THERE REMAINS SOME OFFSHORE BREEZES
THROUGH CANYONS AND VALLEYS.

STRONG HIGH PRESSURE RIDGING WILL CONTINUE THROUGH THE WEEK AND
AFTERNOON TEMPERATURES WILL REMAIN WELL ABOVE NORMAL.  AS THE
OFFSHORE FLOW EASES FURTHER... THE TEMPERATURES IN THE MOUNTAINS AND
INLAND VALLEYS MAY GAIN SOME RELIEF TOMORROW BUT COASTAL LOCATIONS
WILL SEE LITTLE IF ANY.  LOCATIONS NORTH OF VENTURA COUNTY WILL COOL
INTO THE WEEKEND AND THOSE TO THE SOUTH WILL DO SO MUCH MORE SLOWLY.

NIGHTTIME TEMPERATURES WILL COOL MORE READILY WITH THE LACK OF
NOTABLE MOISTURE OR CLOUD COVER.  SOME RESIDUAL BREEZES WILL KEEP
THE AIRMASS IN AREAS NEAR PASSES AND CANYONS STIRRED ENOUGH TO BLUNT
THE COOLING BUT ALL OTHER AREAS WILL GET RELIEF IN THE OVERNIGHT
HOURS.

.LONG TERM...(SAT-TUE)

A WEAK TROUGH MOVES THROUGH THE REGION ON SATURDAY AND BRINGS SOME
CLOUDINESS AND A FIVE TO TEN DEGREE DROP IN AFTERNOON TEMPERATURES.
THE RIDGE REFORMS FAIRLY QUICKLY ON SUNDAY BUT IT IS NOT AS STRONG.
TEMPERATURES WILL REBOUND AS WELL AND THE NEXT WEEK LOOKS TO
BEGIN ALMOST AS WARM AS THIS ONE.

NO PRECIPITATION IS IN THE CURRENT FORECAST THOUGH THERE REMAINS
HOPE FOR A PATTERN SHIFT BY THE END OF THE MONTH.
