325 AM PST WED FEB 10 2016

.SYNOPSIS...
HIGH PRESSURE WILL CONTINUE TO BRING DRY WEATHER TO THE CENTRAL
CALIFORNIA INTERIOR. THESE CONDITIONS WILL EXIST FOR AT LEAST THE
NEXT SEVERAL DAYS ALONG WITH PATCHY NIGHT AND MORNING FOG IN THE SAN
JOAQUIN VALLEY.

&&

.DISCUSSION...
UPPER LEVEL RIDGE WELL IN CONTROL OF THE WEST COAST THIS MIDWEEK
DAY. YET...WHILE LITTLE CHANGE IN EXPECTED FOR THE NEXT SEVERAL
DAYS...A TROF PUSHING INTO THE PACIFIC NORTHWEST/BRITISH COLUMBIA
WILL INTRODUCE SOME CLOUDS OVER THE DISTRICT. THIS CLOUD COVER...
ALONG WITH LESS OF A SOUTHERLY FLOW WILL ALLOW FOR SLIGHT COOLING
DURING THE WEEKEND. THE CHANGE WILL BE ABOUT A 10 DEGREE-F DROP
FROM CURRENT CONDITIONS. HOWEVER...THIS CHANGE IN THE WEATHER WILL
KEEP THE DISTRICT DRY INTO NEXT WEEK. IN THE MEANWHILE...PATCHY
FOG WILL WILL EXIST ACROSS THE SAN JOAQUIN VALLEY DURING THE LATE
NIGHT/EARLY MORNING HOURS.

BY FRIDAY...THE FLOW BECOME MORE ONSHORE AS A WEAK FRONTAL BAND
PUSHES TOWARD THE CALIFORNIA COAST. WHILE THE FRONTAL BAND WILL
SUPPORT THE COOLING TREND...THE FRONT MAYBE TOO WEAK TO PRODUCE
STRONG WINDS DURING ITS PASSAGE THROUGH CENTRAL CALIFORNIA.
SURFACE PRESSURE GRADIENTS FROM SFO TO LAS TIGHTEN TO ONLY ABOUT
5MB...WHICH WOULD TRANSLATE IN SURFACE WINDS OF 10 TO 15 MPH OVER
THE HIGHER TERRAIN.

AFTER THE WEEKEND COOL DOWN...THE RIDGE WILL REBOUND SLIGHTLY
DURING THE EARLY PART OF NEXT WEEK. THIS CHANGE WILL KEEP THE
REGION DRY ALONG WITH A CONTINUATION OF THE FOG PROBLEM. AT THIS
POINT...CONFIDENCE REMAINS HIGH IN THE PERSISTENCE OF THE RIDGE
PATTERN. YET...CHANGE MAY OCCUR OVER THE REGION JUST BEYOND THE
EXTENDED PERIOD AS MODELS INDICATE A POSSIBLE STORM TOWARD NEXT
THURSDAY.
