AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
805 PM PST SAT FEB 25 2012

.SYNOPSIS...
TEMPERATURES ARE EXPECTED TO CONTINUE COOLING FOR THE REMAINDER OF
THIS WEEKEND AS WEAK UPPER LEVEL DISTURBANCES MOVE OVER THE REGION.
GUSTY WINDS AND AREAS OF BLOWING DUST ARE POSSIBLE MAINLY
ALONG THE WEST SIDE OF THE SAN JOAQUIN VALLEY THROUGH THIS EVENING.
A MUCH COLDER LOW PRESSURE SYSTEM WILL THEN BRING FURTHER COOLING
AND A CHANCE OF RAIN AND MOUNTAIN SNOW MONDAY.

&&

.DISCUSSION...
THE UPPER-LEVEL TROUGH THAT MOVED THROUGH CALIFORNIA THIS MORNING
HAS MOVED EAST OF THE REGION...SETTING THE STAGE FOR A COLDER AND
WETTER SYSTEM TO ARRIVE MONDAY.

SKIES WERE MOSTLY CLEAR ACROSS THE CENTRAL CALIFORNIA INTERIOR
TODAY...EXCEPT FOR SOME UPSLOPE CLOUDS THAT DEVELOPED ALONG THE
SOUTHERN SIERRA NEVADA FOOTHILLS THIS AFTERNOON AND PERSISTED INTO
THE EVENING HOURS. GUSTY WINDS WERE REPORTED IN MERCED COUNTY THIS
AFTERNOON...WITH GUSTS TO 40 MPH AT CASTLE AIRPARK AND 35 MPH AT THE
MERCED REGIONAL AIRPORT. THESE WINDS ARE LOCALIZED AND WILL DIMINISH
THIS EVENING...SO COVERED WITH A SIGNIFICANT WEATHER ADVISORY.

THE MAIN IMPACT OF THIS FIRST SYSTEM WAS THE INFLUX OF COOLER AIR
INTO THE REGION. HIGH TEMPERATURES ACROSS THE CENTRAL AND SOUTHERN
SAN JOAQUIN VALLEY THIS AFTERNOON WERE 10-15 DEGREES COOLER THAN
FRIDAY/S NEAR-RECORD HIGHS. EVEN SO...TODAY/S HIGHS WERE WITHIN A
DEGREE OR TWO OF THE 30-YEAR NORMALS.

THE MODELS FORECAST A SHORT-WAVE RIDGE TO MOVE OVER CALIFORNIA
SUNDAY MORNING...BUT THIS RIDGE WILL BE EJECTED EASTWARD RAPIDLY AS
THE NEXT TROUGH DROPS INTO NORTHERN CALIFORNIA SUNDAY AFTERNOON.
THIS TROUGH WILL BRING AN INFLUX OF COLDER AIR AS WELL AS THE NEXT
CHANCE FOR PRECIPITATION OVER THE HANFORD WARNING/FORECAST AREA.

THE MODELS CONTINUE TO FORECAST 700-MB AND 850-MB TEMPERATURES TO
PLUNGE SUNDAY NIGHT. THE 00Z NAM-12 HAS A 700-MB TEMPERATURE OF
-14.5 C OVER FRESNO MONDAY MORNING...WHILE THE 18Z GFS HAS -13.5 C
AND THE 12Z ECMWF HAS -12 C. THIS WOULD PLACE THE SNOW LEVEL AT 2500
FEET...AND POSSIBLY LOWER.

THE 00Z NAM IS IN GOOD AGREEMENT WITH THE 18Z GFS IN GIVING YOSEMITE
AROUND A QUARTER INCH OF LIQUID PRECIPITATION. THIS IS ABOUT TWICE
THE QPF FOR YOSEMITE FROM THE 20Z /NOON PST/ RFC GUIDANCE OF 0.13
INCH. WITH SNOW LEVEL EXPECTED TO PLUMMET INTO THE FOOTHILLS
MONDAY...THE MAJORITY OF THIS PRECIPITATION WILL FALL AS SNOW WITH
UP TO 3 INCHES POSSIBLE...AND POSSIBLY LOCALLY HIGHER AMOUNTS IN
HEAVY SHOWERS.

FOR TEHACHAPI...TEMPERATURES ALOFT ARE ONLY 1-2 C WARMER AND SNOW
LEVELS WILL BE AROUND 500 FEET HIGHER...OR ABOUT 3000 FEET AT MOST.

WITH SNOW LEVELS WELL BELOW THE PASS LEVEL FOR BOTH THE GRAPEVINE
AND TEHACHAPI PASS /4200-4300 FEET/...THERE LIKELY WILL BE LIGHT
ACCUMULATIONS ON BOTH INTERSTATE 5 AND HIGHWAY 58. WHILE SNOW
AMOUNTS SHOULD NOT SIGNIFICANTLY IMPACT TRAFFIC BETWEEN THE SAN
JOAQUIN VALLEY AND THE SOUTHLAND...THE ROADS MAY HAVE ICE OR
SLUSH...WHICH WOULD MAKE TRAVEL DIFFICULT. HAVE ISSUED A SPECIAL
WEATHER STATEMENT /SFOSPSHNX OR WWUS86 KHNX/ ON MONDAY/S STORM.

&&

.PREV DISCUSSION... /ISSUED 245 PM PST SAT FEB 25 2012/
BREEZY CONDITIONS CONTINUE ACROSS THE SAN JOAQUIN VALLEY AND THE
MOUNTAIN AND DESERT AREAS OF KERN COUNTY THIS AFTERNOON IN THE
WAKE OF A DRY COLD FRONT THAT MOVED THROUGH CENTRAL CALIFORNIA
EARLY THIS MORNING. EXPECT THESE WINDS TO DIMINISH THIS EVENING.

THE NEXT TROUGH IS EXPECTED TO ARRIVE ALONG THE NORTHERN
CALIFORNIA COAST SUNDAY AFTERNOON AND MOVE INTO CENTRAL CALIFORNIA
MONDAY. THIS SYSTEM WILL BRING SCATTERED SHOWERS AND ADDITIONAL
COOLING WITH SNOW LEVELS LOWERING TO 2500 TO 3000 FEET. NO
SIGNIFICANT ACCUMULATIONS ARE EXPECTED...WITH LESS THAN A TENTH OF
AN INCH OF RAIN IN THE VALLEY AND ONLY 1-3 INCHES OF SNOW IN THE
SIERRA. THE PASSES IN KERN COUNTY COULD ALSO BE IMPACTED WITH A
DUSTING OF SNOW. THERE IS EVEN A SLIGHT CHANCE SOME THAT RAIN
COULD MIX WITH OR BRIEFLY CHANGE TO SNOW IN THE HIGH DESERTS...
ESPECIALLY OVER AND NEAR HIGHER TERRAIN.

YET ANOTHER TROUGH OF LOW PRESSURE WILL ARRIVE LATE TUESDAY AND
WEDNESDAY. THE 12Z MODELS HAVE COME INTO BETTER AGREEMENT WITH
THIS SYSTEM AND IT LOOKS POTENTIALLY WETTER THAN THE MONDAY
SYSTEM. HAVE INCREASED POPS SLIGHTLY FOR WEDNESDAY AND WEDNESDAY
NIGHT...WITH MAINLY CHANCE POPS FRESNO COUNTY NORTHWARD AND SLIGHT
CHANCE SOUTH. ONCE THIS SYSTEM EXITS ON THURSDAY...A RIDGE OF HIGH
PRESSURE WILL BUILD BACK INTO CALIFORNIA FOR THE END OF THE WEEK.
TEMPERATURES WILL BE AT OR BELOW SEASONAL AVERAGES THE NEXT 7-8
DAYS. COOLEST DAY BEING MONDAY...FOLLOWED BY A WARMING TREND
BEGINNING FRIDAY AND SATURDAY.

&&

.AVIATION...
GUSTY WINDS ALONG THE WEST SIDE OF THE VALLEY AND KERN COUNTY
MOUNTAINS AND DESERT WILL SUBSIDE THIS EVENING. VFR CONDITIONS WILL
PREVAIL ACROSS THE CENTRAL CALIFORNIA INTERIOR THRU 06Z MON.

.AIR QUALITY ISSUES...
