AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HANFORD CA
312 AM PST SUN FEB 25 2007

.SHORT TERM...RADAR SHOWS QUITE A PRECIPITATION SHIELD OVER THE
NORTHERN PART OF THE FORECAST AREA, MAINLY NORTH OF FRESNO COUNTY.
IN THE SIERRA, ECHOES ARE EXTENSIVE AND I HAVE UPPED THE POPS TO
CATEGORICAL AND BASED ON FORECAST QPF, HAVE ISSUED A SNOW ADVISORY
FOR ZONE 96 FOR TODAY THROUGH TONIGHT. COULD SEE UP TO A FOOT AND
A HALF OF FRESH POWDER BY EARLY MONDAY MORNING. THE NEXT CONCERN
THIS MORNING IS THE THREAT OF STRONG GUSTY WINDS OVER THE CREST OF
THE SIERRA, THE EAST SLOPE OF THE SIERRA OF KERN COUNTY AND THE
KERN COUNTY MOUNTAINS AND DESERT. THUS FAR, SOME VERY STRONG WINDS
HAVE MATERIALIZED OVER THE SIERRA CREST AND AS THE JET STREAM SAGS
A LITTLE FARTHER SOUTH TODAY, THE FLOW AT MID LEVELS (AROUND 9000
FEET OR SO) IS PROGGED TO EXCEED 65 KNOTS OVER THE SOUTHERN SIERRA
AND EAST KERN COUNTY AREA. WITH ENOUGH MIXING, THIS MOMENTUM COULD
EASILY TRANSLATE TO THE SURFACE ALONG THE HIGHWAY 14/395 CORRIDOR.
IN ADDITION, EVEN THOUGH THE PROJECTED SURFACE PRESSURE GRADIENT
IS NOT THAT IMPRESSIVE, WINDS ON MOS GUIDANCE ARE AROUND 30 KNOTS
FOR THIS AFTERNOON AT EDWARDS AND LANCASTER. I HAVE ISSUED A WIND
ADVISORY FOR THESE AREAS THROUGH THIS EVENING FOR THE ABOVE
MENTIONED AREAS. FORECAST MODELS KEEP THE THREAT OF PRECIPITATION
CONFINED TO THE NORTH THROUGH MONDAY NIGHT, THEN AS A LOW PRESSURE
AREA DIGS SOUTHWARD AND SWINGS INTO NORTHERN AND CENTRAL
CALIFORNIA ON TUESDAY THE THREAT OF PRECIPITATION COVERS MOST OF
THE FORECAST AREA. THIS SYSTEM IS PROJECTED TO HAVE AMPLE COLD AIR
FOR RATHER LOW SNOW LEVELS. A STRONG JET STREAM IS ALSO PROGGED TO
MOVE INTO SOUTHERN CALIFORNIA ON TUESDAY AND THIS SHOULD DO TWO
THINGS. THE FIRST IS AN ENHANCEMENT OF SNOW RATES IN THE SIERRA
AND ANY WEST FACING MOUNTAIN SLOPE. THE CONVERSE WILL BE AN
ENHANCED RAIN SHADOWING EFFECT OVER THE SAN JOAQUIN VALLEY
(ESPECIALLY THE SOUTH END) AND OVER THE KERN COUNTY DESERTS. DAY
SHIFT WILL LIKELY BE ISSUING A WINTER STORM WATCH TO COVER THIS
SCENARIO. THE GRIDS ALREADY INDICATE A HEAVY WIND AND SNOW EVENT
FOR TUESDAY. THATS ALL FOR NOW.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY...GOOD MODEL CONSENSUS
PLACES THE LONGWAVE TROUGH AXIS OVER CALIFORNIA TO BEGIN THE PERIOD.
COLD AIR ALOFT AND ADDITIONAL ENERGY RIDING DOWN THE BACKSIDE OF
THE TROUGH WILL KEEP A CHANCE OF SHOWERS GOING FOR MUCH OF THE
DISTRICT TUESDAY NIGHT TAPERING OFF TO SLIGHT CHANCES ON WEDNESDAY.
PRECIP WILL BE FAVORED OVER THE HIGHER ELEVATIONS WHERE OROGRAPHICS
PROVIDE LIFT ENHANCEMENT. H85 TEMPS AND 1000-500MB THICKNESS VALUES
PORTEND A SNOW LEVEL FALLING WELL INTO THE SIERRA FOOTHILLS
AGAIN...APRROX 2000 FEET TUESDAY NIGHT. SNOW BELOW THE GRAPEVINE
PASS WOULD BE EXPECTED AS WELL. A FEW MODELS DEPICT A WEAK WAVE IN
THE NORTHWEST FLOW ALOFT PUSHING INTO CENTRAL CA ON THURSDAY. BUT
DOES NOT LOOK LIKE MUCH AND WILL LIMIT POPS TO AROUND 10 WITH NO
MENTION OF WX. AN UPPER RIDGE BUILDS IN FRIDAY AND SATURDAY WITH
CLEARING SKIES AND MODERATING TEMPERATURES. WINDS IN THE KERN
MOUNTAINS AND DESERT SHOULD INCREASE WEDNESDAY WITH A TIGHTENING
ONSHORE PRESSURE GRADIENT AND MAY REACH ADVISORY LEVEL. TEMPERATURES
SEVERAL DEGREES BELOW NORMAL ON WEDNESDAY TREND SLIGHTLY HIGHER
THURSDAY AND MORE SO FRIDAY AND SATURDAY ENDING UP NEAR CLIMO.

.AVIATION...MVFR CONDITIONS OVER THE SOUTHERN SIERRA NEVADA WITH
AREAS IFR IN RAIN AND SNOW FROM FRESNO COUNTY NORTH THROUGH 12Z
MONDAY. ELSEWHERE...VFR CONDITIONS PREVAILING.

&&

.AIR QUALITY ISSUES...
NONE

&&

.HNX WATCHES/WARNINGS/ADVISORIES...
SNOW ADVISORY UNTIL 4 AM PST MONDAY FOR CAZ096.
WIND ADVISORY UNTIL 8 PM PST THIS EVENING FOR CAZ095-098-099.
