.SYNOPSIS...DRY WEATHER IS EXPECTED OVERNIGHT AND TODAY AS WEAK HIGH
PRESSURE BUILDS OVER THE REGION. A WEAK FRONT MOVING THROUGH THE
PACIFIC NORTHWEST WILL BRING A CHANCE OF LIGHT RAIN TO DEL NORTE
COUNTY LATE MONDAY NIGHT INTO TUESDAY.
&&
.SHORT TERM...TODAY THROUGH THU...A RELATIVELY FLAT RIDGE AXIS WILL
TRAVERSE THE WEST COAST TODAY. H5 RISES OF NEARLY 6 DM WILL LEAD TO
SEVERAL DEGREES OF WARMING FOR INTERIOR LOCATIONS THIS AFTERNOON
COMPARED TO YESTERDAY. FOR THE REDWOOD COAST...EXPECT MOSTLY CLOUDY
SKIES TO PREVAIL THROUGH MOST OF THE DAY WITH LIGHT WINDS PREVAILING.
THE NEXT WEATHER-MAKER FOR NORTHWEST CALIFORNIA IS A WEAK FRONT NOW
OVER THE NORTHEAST PACIFIC. MODELED MOISTURE/QPF FIELDS AS WELL AS
SREF POPS ARE IN GOOD AGREEMENT IN KEEPING MEASURABLE RAINFALL
CONFINED TO MAINLY DEL NORTE COUNTY...AND HAVE TRIMMED POPS BACK
SLIGHTLY FOR OTHER LOCATIONS WILL KEEPING CHANCE POPS NEAR THE
OREGON BORDER. HIGH PRESSURE BUILDING INTO THE WEST COAST AT THE
SURFACE AND ALOFT WILL LEAD TO BREEZY NORTH WINDS ALONG THE COAST BY
LATE WEDNESDAY INTO THURSDAY. KL
.PREV LONG TERM...THU NIGHT THROUGH SUN...MEDIUM RANGE SOLUTIONS ARE
STILL SOMEWHAT INCONSISTENT FOR THIS PERIOD BUT IN GENERAL ARE
SLOWLY FOLLOWING THE EURO`S LEAD IN DEVELOPING A DEEP TROUGH ACROSS
THE GREAT BASIN. WE HAVE THEREFORE TRENDED TEMPERATURES DOWN A
LITTLE...BUT THIS PATTERN STILL LOOKS DRY GIVEN THE OVERLAND
TRAJECTORY OF SHORTWAVES. THESE WILL ALSO REINFORCE THE OFFSHORE
FLOW ACROSS THE DISTRICT...SO CONSIDERABLE SUNSHINE IS EXPECTED EVEN
AT THE COAST WITH COLD OVERNIGHT TEMPERATURES IN PROTECTED VALLEYS
AND ALONG THE COAST. THE FIRST WIDESPREAD FROSTS MAY BE AN ISSUE
FOR THE INLAND VALLEYS FOR THE END OF THE WEEK. BURGER
&&
.AVIATION...EXPECT CEILINGS TO LIFT MID MORNING AS A WEAK COLD FRONT
APPROACHES THE REGION...AND VFR CONDITIONS SHOULD PREVAIL FOR MOST
OF THE DAY. EXPECT MVFR CEILINGS NORTH OF CAPE MENDOCINO IN THE LATE
EVENING AS THE FRONT NEARS. TH
&&
.MARINE...QUIET CONDITIONS OVER THE WATERS THROUGH TUESDAY.
NORTHERLY WINDS WILL BEGIN TO INCREASE TUESDAY AS HIGH PRESSURE WILL
MOVE OVER THE WATERS AS THERMAL LOW PRESSURE DEVELOPS OVER SOUTHERN
CALIFORNIA. EXPECT GALES OVER THE OUTER WATERS BY WED MORNING..AND
TO PERSIST THROUGH THURSDAY. SHORT PERIOD WAVES WILL BECOME
INCREASINGLY LARGE AND DANGEROUS WITH THIS WIND EVENT...WITH WIND
WAVES BUILDING TO NEAR 15 FT. IT IS TOO EARLY TO ISSUE A WATCH...BUT
IF GALE AND HAZ SEAS POTENTIAL CONTINUES...A WATCH FOR GALES AND
HAZARDOUS SEAS WILL LIKELY BE ISSUED WITH THE AFTERNOON FORECAST
PACKAGE. TH
&&
.EKA WATCHES/WARNINGS/ADVISORIES...NONE.
