AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
126 PM PST SUN FEB 7 2016

.SYNOPSIS...
HIGH PRESSURE WILL CONTINUE TO BRING DRY WEATHER TO THE CENTRAL
CALIFORNIA INTERIOR FOR THE NEXT SEVERAL DAYS WITH PATCHY NIGHT
AND MORNING FOG IN THE SAN JOAQUIN VALLEY. A DAY TO DAY WARMING
TREND WILL BRING HIGH TEMPERATURES ABOVE NORMAL THROUGH THE MIDDLE
OF THE WEEK.

&&

.DISCUSSION...
HIGH PRESSURE WILL CONTINUE TO BRING MAINLY CLEAR SKIES TO THE
REGION THE NEXT FEW DAYS. THE RIDGE IS CENTERED JUST OFF THE
CALIFORNIA COAST THIS AFTERNOON WITH SURFACE HIGH PRESSURE
CENTERED OVER THE GREAT BASIN. THIS IS BRINGING AN OFFSHORE
PRESSURE GRADIENT WHICH WILL RESULT IN LOCALLY STRONG EASTERLY
WINDS OVER THE TEHACHAPI AND SAN EMIGDIO MOUNTAINS NEAR THE
GRAPEVINE. A WIND ADVISORY REMAINS IN EFFECT FOR THAT AREA THROUGH
MONDAY AFTERNOON.

IN THE SAN JOAQUIN VALLEY...THE CLEAR SKIES AND LIGHT WINDS WILL
KEEP THE THREAT OF LATE NIGHT AND EARLY MORNING FOG FOR THE NEXT
FEW DAYS...WITH THE GREATEST CHANCE BEING DOWN THE CENTER OF THE
VALLEY. AS TEMPERATURES WARM AND THE GROUND CONTINUES TO DRY...THE
AREAL COVERAGE OF THE FOG SHOULD BECOME LESS AND LESS EACH DAY.

FORECAST MODELS MOVE THE HIGH PRESSURE CENTER NORTHEAST INTO
SOUTHERN OREGON TONIGHT AND MONDAY AND THEN SLOWLY MOVE THE
CENTER OF HIGH PRESSURE TO THE EAST. HEIGHTS ARE IMPRESSIVE WITH
FORECAST MODELS INTENSIFYING THE ANTICYCLONE TO LEVELS AT AROUND
5850 METERS BY TUESDAY. THIS WILL ALLOW TEMPERATURES TO RISE TO
WELL ABOVE MID FEBRUARY NORMALS AND SOME RECORDS MAY BE EXCEEDED.

AS THE RIDGE AXIS SHIFTS EAST OF THE SIERRA NEVADA MONDAY
EVENING...THE OFFSHORE FLOW WILL DECREASE AND WINDS WILL RETURN TO
A LIGHT DIURNAL PATTERN TUESDAY THROUGH FRIDAY.

EVEN WITH THE EASTERLY SHIFT IN THE RIDGE THE MEDIUM RANGE MODELS
ARE IN GOOD AGREEMENT THAT THE STORM TRACK WILL REMAIN TO THE
NORTH OF CENTRAL CALIFORNIA AT LEAST THROUGH NEXT WEEKEND.
HOWEVER...SOME HIGH CLOUDS WILL LIKELY MOVE INTO THE REGION AT
TIMES DURING THE LATTER HALF OF THE WEEK.

&&
