AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
509 PM PDT FRI OCT 19 2007

UPDATED FOR AIR QUALITY ADVISORY

.DISCUSSION...A STORM SYSTEM CONTINUES TO MOVE OVER THE PACIFIC
NORTHWEST AND NORTHERN CALIFORNIA THIS AFTERNOON...BUT STILL WELL
NORTH OF THE HANFORD CWFA. THE SYSTEM WILL BRING A CHANCE OF RAIN
AND SNOW SHOWERS MAINLY FROM FRESNO COUNTY NORTHWARD LATER TONIGHT.
CLOUDS WILL LIKELY BANK UP IN THE SOUTH END OF THE SAN JOAQUIN
VALLEY OVERNIGHT AND COULD SEE SOME LIGHT RAIN SQUEEZED OUT OF
THESE UPSLOPE CLOUDS ALONG THE NORTH SLOPES OF THE KERN MOUNTAINS
IN THE MORNING. A FEW SHOWERS COULD ALSO HANG ON IN THE SIERRA
AFTER 12Z SO HAVE PUT SOME LOW POPS IN THOSE AREAS FOR THE
MORNING. BY AFTERNOON SKIES WILL BE CLEARING.

THE BIGGER PROBLEM WITH THIS SYSTEM WILL BE THE THREAT OF HIGH
WINDS OVER THE KERN COUNTY MOUNTAINS AND DESERT SATURDAY AND
SATURDAY NIGHT. WINDS WILL BECOME GUSTY OVER THE CREST OF THE
SIERRA TONIGHT AND EARLY SATURDAY AS THE UPPER JET BEGINS TO DROP
SOUTH. WINDS WILL ALSO BEGIN TO INCREASE IN THE KERN MOUNTAINS
TOWARD MORNING...BUT ARE EXPECTED TO STAY BELOW ADVISORY CRITERIA.
HOWEVER...THE 12Z AND 18Z MODEL RUNS CONTINUE TO VERY STRONG WITH
PRESSURE GRADIENTS SATURDAY...AROUND 18 MILLIBARS FROM SAN
FRANCISCO TO LAS VEGAS SATURDAY AFTERNOON AND 9 MILLIBARS FROM
BAKERSFIELD TO DAGGETT DURING THIS SAME TIME FRAME. WITH THE
STRONG JET STREAM FLOWING JUST TO THE NORTH...AS THE SPEED MAX
MOVES TO THE NORTH STRONG DOWNWARD MOTION WILL HELP BRING MOMENTUM
TOWARDS THE SURFACE. WITH MODEL PROGS INDICATING 50-65 KNOTS OF
FLOW IN THE 9000-18000 FOOT LAYER...THERE IS A STRONG POTENTIAL
FOR MOUNTAIN WAVE ROTOR CONDITIONS TO AGAIN OCCUR OVER THE DESERTS
AND MOUNTAINS. WITH VERY DRY SOIL CONDITIONS OVER THE KERN
DESERT...THE THREAT OF BLOWING DUST AND SAND WILL OCCUR...
ESPECIALLY ON SATURDAY AFTERNOON AND EVENING. BY LATE SATURDAY
NIGHT...THE FLOW WILL SHIFT TO THE NORTH AND THEN THE NORTHEAST ON
SUNDAY. LOCATIONS IN THE KERN DESERT AND MOUNTAINS THAT ARE
NORMALLY SUSCEPTIBLE TO HIGHER WINDS IN THE NORTHEAST FLOW INCLUDE
THE INDIAN WELLS VALLEY AND LOCATIONS JUST DOWNWIND OF THE EL PASO
MOUNTAINS INCLUDING RED ROCK CANYON AND CANTIL. A HIGH WIND WATCH
REMAINS IN EFFECT FOR THE WINDS FROM SATURDAY THROUGH SATURDAY
NIGHT...HOWEVER SUNDAY MORNING SHOULD BE MONITORED FOR LOCAL
STRONG NORTHEAST WINDS.

BY SUNDAY AFTERNOON...THE FLOW BEGINS TO SHIFT TO A NORTHEAST TO
EAST DIRECTION AND THIS SHOULD LIMIT THE THREAT OF STRONG WINDS TO
A FEW ISOLATED PEAKS IN THE EL PASO AND TEHACHAPI MOUNTAINS.

A STRONG RIDGE OF HIGH PRESSURE BUILDS OVER THE REGION MONDAY
AND REMAINS THROUGH WEDNESDAY FOR WARMER TEMPERATURES. THE RIDGE
WEAKENS THURSDAY AS A TROUGH OF LOW PRESSURE DROPS INTO THE
PACIFIC NORTHWEST.

.AVIATION...MVFR CONDITIONS DUE TO CIGS/VISIBILITY IN SCATTERED
SHOWERS BETWEEN 06Z AND 18Z SATURDAY. OTHERWISE VFR CONDITIONS WILL
PREVAIL ACROSS THE CENTRAL CALIFORNIA INTERIOR THROUGH 00Z SUNDAY.
