647 AM PST SUN NOV 3 2013

.SYNOPSIS...A COLDER AIR MASS WILL PERSIST OVER THE REGION FOR THE
NEXT COUPLE OF DAYS. WARMER WEATHER WILL RETURN BY MIDWEEK AS WEAK
HIGH PRESSURE BUILDS BACK IN OVER THE WESTERN STATES.

&&

.DISCUSSION...A COLD AIR MASS CONTINUES TO SETTLE ACROSS THE REGION
WITH TEMPERATURES FALLING INTO THE 30S AND 20S ACROSS MANY INTERIOR
LOCATIONS OVERNIGHT. SOME AREAS OF MENDOCINO COUNTY HAVE STAYED UP IN THE
UPPER 30S AND LOWER 40S DUE TO SOME STRONGER NORTHERLY WINDS. A
REPEAT OF THIS PAST NIGHT IS EXPECTED TONIGHT WITH TEMPERATURES
LIKELY A DEGREE OR TWO COLDER AND WINDS LIGHTER. SINCE A FROST
ADVISORY WAS RAISED OVERNIGHT FOR THE NORTH COAST INTERIOR ZONE AND
STILL RUNS THROUGH 8 AM...THE FREEZE WATCH WAS CONTINUED. HOWEVER
CONFIDENCE IS HIGH IN AT LEAST FROST CONDITIONS FOR INTERIOR AREAS
TONIGHT. WILL GIVE THE DAY SHIFT ANOTHER LOOK AT IT TODAY TO DECIDE
IF A FREEZE WARNING OR A FROST ADVISORY IS NEEDED FOR THE INTERIOR
ZONES AND WHETHER OR NOT A FROST ADVISORY MAY BE NEEDED FOR THE
COASTAL ZONES.

A WARM FRONT WILL BRING A CHANCE FOR RAIN TO HUMBOLDT AND DEL NORTE
COASTS LATE MONDAY INTO TUESDAY. ANY ACCUMULATIONS WILL BE LIGHT
WITH MODELS TRENDING TOWARD LESS RAINFALL RATHER THAN MORE. WEAK
RIDGING WILL BUILD OVERHEAD ON WEDNESDAY WITH DRY CONDITIONS
EXPECTED. MODELS ARE HAVING A VERY DIFFICULT TIME WITH THE LATE WEEK
SYSTEM WITH THE GFS TRENDING WEAKER AND FARTHER NORTH WHILE THE
ECMWF HAS KEPT VERY SIMILAR TO PREVIOUS RUNS INDICATING A TROUGH
ADVANCING TOWARD THE PACIFIC NORTHWEST COAST BRINGING RAIN TO
NORTHERN CALIFORNIA. LOWERED POPS SLIGHTLY ON THURSDAY INTO FRIDAY
CONSIDERING THE TREND OF THE GFS...BUT POPS ARE STILL WELL ABOVE
CLIMO. NEAR CLIMO TO SLIGHTLY ABOVE CLIMO POPS ARE CONTINUED INTO
NEXT WEEKEND AS A DEEP TROUGH IS CURRENTLY FORECAST BY BOTH MODELS
TO DEVELOP OFF THE WEST COAST LEAVING THE REGION IN DIFFLUENT
ONSHORE FLOW ALOFT. RPA

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED AT ALL TERMINALS TODAY. HIGH
CLOUDINESS WILL INCREASE DURING THE MORNING HOURS AND SOME OPEN
CELLULAR STRATOCUMULUS WILL AFFECT THE IMMEDIATE COAST. WINDS WILL
BE MUCH LIGHTER THAN ON SAT...BUT SOME GUSTS OF 15 TO 20 KTS ARE
POSSIBLE BY AFTERNOON. SEC
