.SYNOPSIS...A WEAK FRONT WILL BRING THE CHANCE OF LIGHT RAIN TO THE
COASTAL AREAS NORTH OF CAPE MENDOCINO THIS MORNING. ELSEWHERE...HIGH
PRESSURE WILL BRING DRY WEATHER AND WARMING TEMPERATURES THROUGH THE
WEEKEND. A STORM SYSTEM APPROACHING THE REGION WILL BRING COOLER
TEMPERATURES AND A CHANCE FOR SHOWERS EARLY NEXT WEEK.

.DISCUSSION...A WEAK DISTURBANCE MOVING DOWN THE FRONT SIDE OF A
BUILDING RIDGE ACROSS THE NE PAC IS BRINGING INCREASED SKY COVER AND
A FEW 88D RETURNS CAPABLE OF SQUEEZING OUT A FEW SPRINKLES EARLY
THIS MORNING. A SCHC OF SHOWERS WILL CONTINUE THROUGH THE MORNING AS
THE WEAK DISTURBANCE AND ASSOCIATED WEAK SFC FRONT CLIP THE NRN
PORTION OF CWA. THE PRESSURE GRADIENT WILL RELAX SLIGHTLY N OF CAPE

CONDITIONS WILL CONTINUE S OF THE CAPE. BREEZY N TO NW WINDS ALONG
THE COAST AND DRY...WARM WX WILL PERSIST THROUGH THE WEEKEND AS HIGH
PRESSURE OFFSHORE COMBINES WITH A THERMAL TROUGH ACROSS THE

THE RIDGE WILL KEEP MOST OF THE ENERGY WITH THIS SYSTEM WELL TO THE
N SUFFICIENT COOLING ALOFT WILL LOWER SNOW LEVELS TO 3-4 KFT TUE.
ALTHOUGH MODEL SOLUTIONS DIFFER BEYOND WED...THE GENERAL CONSENSUS
IS FOR A BROAD TROUGH ACROSS THE W COAST. THE MORE PROGRESSIVE
