AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
435 AM PDT SUN MAR 13 2016

.SYNOPSIS...HEAVY RAINS WILL CONTINUE TODAY AS THE LAST IN A
SERIES OF STORM SYSTEMS MOVES THROUGH THE REGION. ISOLATED TO
SCATTERED SHOWERS WILL LINGER ACROSS PORTIONS OF NORTHWEST
CALIFORNIA MONDAY INTO TUESDAY. A DRYING AND WARMING TREND WILL
BEGIN MID WEEK.

&&

.SHORT TERM...THROUGH WEDNESDAY...THE LAST IN THE RECENT SERIES OF
WET SYSTEMS WILL MOVE THROUGH NORTHWEST CALIFORNIA TODAY. PERIODS OF
HEAVY RAIN ARE LIKELY THIS MORNING WITH RAINFALL RATES APPROACHING A
HALF INCH PER HOUR IN FAVORED UPSLOPE LOCATIONS. WITH SOILS
SATURATED...EVEN WITH NOT PARTICULARLY IMPRESSIVE ADDITIONAL
RAINFALL OF 1 TO 2 LOCALLY 4 INCHES EXPECTED...RIVERS...STREAMS
AND CREEKS SHOULD ALL RISE SHARPLY. THERE IS ALREADY EVIDENCE OF
RAPID RISE DEVELOPING ON SOME OF THE TRIBUTARIES OF THE EEL AND
MAD RIVERS FROM EARLY MORNING RAINS. AS THE COLD FRONT APPROACHES
THE AREA LATER THIS MORNING THE HEAVIEST RAIN RATES WILL DEVELOP
AND AREAL FLOODING WILL BECOME A CONCERN. THUS THE AREAL FLOOD
WATCH REMAINS IN EFFECT. SNOW LEVELS WILL RISE IN ADVANCE OF THE
FRONT TO OVER 5000 FEET THIS MORNING...EVENTUALLY BRINGING AN END
TO SNOW ON HIGHWAY 36.

THE COLD FRONT WILL MOVE THROUGH THE REGION THIS AFTERNOON USHERING
IN COOLER AND MORE UNSTABLE AIR. SCATTERED SHOWERS WILL DEVELOP
BEHIND THE FRONT AND SNOW LEVELS WILL ONCE AGAIN CRASH DOWN TO NEAR
2500-3000 FEET. SHOWER ACTIVITY SHOULD BE NUMEROUS ENOUGH TO WARRANT
A WINTER WEATHER ADVISORY FOR ELEVATIONS OVER 3500 FEET LATE TONIGHT
THROUGH MONDAY MORNING AS TRAVEL COULD BECOME IMPACTED.

ONSHORE FLOW WILL DECREASE MONDAY NIGHT INTO TUESDAY AS UPPER LEVEL
RIDGING BUILDS OVER THE WEST COAST. ANY SHOWER ACTIVITY WILL BECOME
CONFINED TO AREAS NORTH OF CAPE MENDOCINO AND BE LIGHT. SNOW LEVELS
WILL ALSO RISE ON TUESDAY BACK OVER 4500 FEET. A WARMING TREND WILL
BEGIN MID WEEK WITH HIGHS REBOUNDING BACK INTO THE 60S AND EVEN 70S
IN SOUTHERN INTERIOR MENDOCINO COUNTY. HOWEVER OVERNIGHT LOWS MAY
REMAIN QUITE COOL WITH FROST POSSIBLE TUESDAY MORNING IN INTERIOR
MENDOCINO COUNTY DEPENDING ON CLOUD COVER. RPA

.LONG TERM...THURSDAY THRU SATURDAY...HIGH AMPLITUDE RIDGING IS
FORECAST TO DEVELOP OVER THE PACIFIC NORTHWEST THIS WEEK AS A
DEEP TROUGH DIGS ACROSS THE NORTHERN PACIFIC. THIS WILL PROMOTE
WARM AND DRY WEATHER ACROSS NORTHERN CALIFORNIA WITH INTERIOR
AREAS EXPECTED TO GET SOME ABOVE NORMAL DAYTIME TEMPERATURES. SOME
EASTERLY FLOW WILL DEVELOP EARLY THURSDAY MORNING AS A THERMAL
SURFACE TROUGH SHIFTS WEST. THIS COULD BRING SLIGHTLY WARMER
TEMPERATURES AND MOSTLY CLEAR CONDITIONS TO COASTAL AREAS MAKING
FOR A PRETTY NICE DAY ON THURSDAY. THEN BY NEXT WEEKEND MODELS
INDICATE THE UPPER TROUGH OFFSHORE WILL PINWHEEL DISTURBANCES OVER
THE AREA. MODELS SUGGEST THERE WILL BE A POTENTIAL FOR LIGHT RAIN
SATURDAY AND EVEN SUNDAY BUT UNCERTAINTY IS HIGH AT THIS TIME.
WITH THE HIGH AMPLITUDE RIDGE NEARBY, A LIKELY OUTCOME IS THE
RIDGE WILL SIGNIFICANTLY WEAKEN THESE APPROACHING SYSTEMS AND/OR
RESTRICT ANY RAINFALL OFFSHORE. IT IS STILL TOO EARLY TO TELL SO
CLIMO POPS WERE USED LATE IN THE FORECAST FOR NOW. WE WILL ADJUST
AS CONFIDENCE IMPROVES. KML

&&

.AVIATION...PERIODS OF HEAVY RAIN ARE FORECAST FOR THIS MORNING AS A
FRONTAL SYSTEM MOVES THROUGH THE REGION. IFR OR EVEN LIFR CONDITIONS
WILL BE POSSIBLE DURING THE HEAVIEST RAINFALL. OTHERWISE VFR OR MVFR
CONDITIONS WILL DOMINATE. CONDITIONS WILL IMPROVE OVERNIGHT AS
SHOWER ACTIVITY SUBSIDES...THOUGH SOME MVFR CIGS MAY BECOME TRAPPED
IN INTERIOR VALLEYS.

GUSTY WINDS WILL PERSIST THROUGHOUT THE DAY ALONG THE COAST AND ON
RIDGE TOPS. SOME GUSTS MAY MIX INTO INTERIOR VALLEYS DURING THE
AFTERNOON HOURS TODAY. RPA

&&

.MARINE...A PASSING FRONT WILL BRING SOUTHERLY GALES TO THE WATERS
EARLY THIS MORNING WITH WINDS TURNING ONSHORE BY THE AFTERNOON AND
DECREASING FURTHER TONIGHT. THE HIGHEST GUSTS WILL REACH NEAR 45 KT
OFFSHORE WITH GUSTS NEAR SHORE APPROACHING 35 TO 40 KT ESPECIALLY
NEAR CAPE MENDOCINO. JUST AS GALES SETTLE, A LARGE WESTERLY SWELL
WILL BUILD ACROSS THE WATERS CAUSING THE SEA STATE TO APPROACH 20 FT
AND GENERATE 23 TO 25 FT BREAKERS IN THE SURF ZONE. A HAZARDOUS SEAS
WARNING WILL LIKELY BE NEEDED FOLLOWING THE GALES FOR THE ENTIRE
COASTAL WATERS THIS AFTERNOON WHILE SMALL CRAFT ADVISORIES WILL BE
NEEDED TO ACCOUNT FOR THE FRESH WINDS.

MOVING INTO THE UPCOMING WEEK, HIGH PRESSURE WILL NOSE OVER THE
REGION AND ALLOW THE PRESSURE GRADIENT TO RELAX AND WINDS TO
DECREASE MONDAY AND TUESDAY. WHEN WE SEE HIGH PRESSURE WE USUALLY
SEE THE DEVELOPMENT OF A SURFACE THERMAL TROUGH. THIS WILL CAUSE
NORTH WINDS TO INCREASE TO 15 TO 20 KT ON WEDNESDAY. WINDS SHOULD
DECREASE AGAIN LATE IN THE WEEK AS AN APPROACHING TROUGH ATTEMPTS TO
BUST UP THE RIDGE BUT WE WILL HAVE TO WAIT AND SEE HOW THE UPPER
LEVEL PATTERN PANS OUT. MEANWHILE THE WESTERLY SWELL WILL DIMINISH
THROUGH THE WEEK AND SHORTER PERIOD WAVES SHOULD DEVELOP IN RESPONSE
TO THE NORTH WINDS MID-WEEK. KML

&&

.HYDROLOGY...AN AREAL FLOOD WATCH REMAINS IN EFFECT FOR THE REGION
THROUGH TONIGHT WITH PERIODS OF HEAVY RAIN EXPECTED THIS MORNING AND
POSSIBLY INTO THE AFTERNOON. RIVERS...STREAMS AND CREEKS WILL ALL
RISE SHARPLY IN RESPONSE TO THE HEAVY RAIN. THUS SMALL STREAM
FLOODING IS LIKELY. SOME OF THE MAIN STEM RIVERS WILL ALSO
APPROACH CRITICAL LEVELS INCLUDING THE NAVARRO WHICH MAY REACH
FLOOD STAGE THIS AFTERNOON...THE RUSSIAN WHICH IS FORECAST TO
APPROACH 15 FEET THIS EVENING...AND THE MAD RIVER AND EEL RIVER AT
FERNBRIDGE WHICH ARE BOTH FORECAST TO EXCEED MONITOR STAGES
THROUGH THE DAY. ALL MAIN STEM RIVERS WILL FALL ON MONDAY AS RAIN
DECREASES. RPA
