High Wind in California, June 11 to 13, 2001

INTERIOR CENTRAL CALIFORNIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
907 AM PDT MON JUN 11 2001

MAIN LOW CENTERED SITUATED NEAR VANCOUVER ISLAND THIS MORNING
WITH A NUMBER OF SHORTWAVES MOVING THROUGH A BROAD TROUGH OVER THE WEST
COAST. ONE SHORTWAVE IS MOVING ACROSS THE CWFA AT THE MOMENT WITH
ANOTHER ONE APPROACHING THE NORCAL COAST. MARINE LAYER NOT TOO DIFFERENT
FROM YESTERDAY MORNING RANGING FROM ABOUT 1000 FEET ON THE VBG RAOB TO
1500 FEET AT OAK. SHORTWAVES WILL WILL HAVE LITTLE AFFECT ON THE
FORECAST AREA OTHER THAN TO ENHANCE PRESSURE GRADIENTS AND BRING
SLIGHTLY COOLER TEMPERATURES. GRADIENTS ACROSS THE COASTAL RANGE HAVE
RELAXED SLIGHTLY FROM 24 HOURS AGO WHILE GRADIENTS FROM THE VALLEY TO
THE DESERT HAVE INCREASED ABOUT 1 TO 1.5 MILLIBARS. JAWBONE RAWS GUSTING
OVER 40 MPH THIS MORNING. THIS IN COMBINATION WITH INCREASED GRADIENTS
AND A NARROW ZONE OF SUBSIDENCE BEHIND THE SHORTWAVE OVER THE AREA
SHOULD BRING WINDY CONDITIONS TO THE DESERT TODAY...ESPECIALLY BELOW
PASSES.

NEXT SHORTWAVE PROGGED TO MOVE INLAND AND ACROSS THE FORECAST AREA
OVERNIGHT. MUCH BETTER SUBSIDENCE PROGGED ACROSS THE TEHACHAPI
MOUNTAINS AND DESERT AREA WITH THIS FEATURE. THUS EXPECT WINDS TO
REALLY GET HOWLING OVERNIGHT BELOW THE PASSES IN THE DESERT TONIGHT.
H5 HEIGHTS DECREASE TUESDAY BUT FORECAST SOUNDINGS SHOW ONLY SLIGHT
COOLING OF TEMPERATURES UP THROUGH H7 LEVEL. LOOKS LIKE ANOTHER DAY OF
NEAR NORMAL TEMPERATURES AND BREEZY TO LOCALLY WINDY CONDITIONS TUESDAY.

BRIEF LOOK AT THE EXTENDED MODELS SHOW THE LONGWAVE TROUGH OVER THE
WEST COAST TRANSITIONING TO THE EAST WITH MORE OF A ZONAL FLOW OR FLAT
RIDGING OVER THE AREA. DRY CONDITIONS WITH NEAR NORMAL TEMPERATURES AS
CURRENTLY INDICATED LOOKS GOOD.

CURRENT FORECAST LOOKS ON TRACK.

.HNX...WIND ADVISORY THIS AFTERNOON AND EVENING BELOW THE PASSES IN
       THE KERN COUNTY DESERTS.
