AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
338 PM PST THU MAR 10 2016

.SYNOPSIS...MULTIPLE STORM SYSTEMS WILL BRING PERIODS OF HEAVY
RAIN TO NORTHWEST CALIFORNIA TONIGHT THROUGH THE WEEKEND.
FLOODING WILL BE POSSIBLE IN LOW LYING AREAS...FIRST ACROSS
MENDOCINO COUNTY TONIGHT AND TOMORROW...AND LATER IN THE WEEKEND
ACROSS THE REMAINDER OF THE REGION.

&&

.DISCUSSION...

.SHORT TERM...TODAY THROUGH MONDAY...AS EXPECTED...THE HEAVY RAIN
THAT IMPACTED NORTHWEST CALIFORNIA LAST NIGHT AND EARLY THIS
MORNING HAS PUSHED SOUTH OF THE REGION INTO SONOMA COUNTY AND THE
SACRAMENTO VALLEY/NORTHERN SIERRA...WHERE IT HAS REMAINED MORE OR
LESS STATIONARY OVER THE PAST SEVERAL HOURS WITH FLUCTUATING
INTENSITY. AS A RESULT...MENDOCINO COUNTY HAS BEEN GIVEN A
TEMPORARY REPRIEVE...ALLOWING STANDING WATER AND SWOLLEN CREEKS TO
GRADUALLY DRAIN THROUGH THE DAY TODAY. THIS WILL BE A SHORT-LIVED
BREAK...HOWEVER...AS AN APPROACHING SHORTWAVE WILL MOVE ONTO THE
CALIFORNIA COAST OVERNIGHT TONIGHT AND CAUSE MODERATE TO HEAVY
RAIN TO REDEVELOP ACROSS THE REGION. SATELLITE IMAGERY REVEALS TWO
DISTINCT PLUMES OF MOISTURE...THE FIRST OF WHICH IS CURRENTLY
RESULTING IN THE PREVIOUSLY MENTIONED HEAVY RAIN TO OUR SOUTH AND
EAST...AND THE SECOND OF WHICH IS ASSOCIATED WITH THE DIGGING
SHORTWAVE CURRENTLY LOCATED AT AROUND 135 W LONGITUDE. AS THIS
SHORTWAVE MOVES CLOSER TO THE COAST...IT WILL BEGIN TO CLOSE OFF
AND DETACH FROM ITS PARENT TROUGH...AND ALSO PIVOT SLIGHTLY TO
THE NORTH AS IT MAKES LANDFALL. MEANWHILE...THE TWO PREVIOUSLY
MENTIONED PLUMES OF MOISTURE WILL MERGE INTO ONE AND TAKE ON A
MORE MERIDIONAL ORIENTATION...WHICH WILL BRING AMPLE RAINFALL BACK
INTO THE REGION OVERNIGHT TONIGHT THROUGH THE FIRST HALF OF
TOMORROW...PARTICULARLY ACROSS MENDOCINO COUNTY AND THE EASTERN
SLOPES OF THE KLAMATH MOUNTAINS. NOT SURPRISINGLY...MODELS HAVE
STRUGGLED MIGHTILY WITH THE COMPLICATED DYNAMICS INVOLVED WITH
THIS PARTICULAR SETUP...AND CONTINUE TO FLUCTUATE REGARDING JUST
HOW MUCH ADDITIONAL RAIN WILL FALL IN NORTHWEST CALIFORNIA. THIS
IS MOST CONCERNING FOR MENDOCINO COUNTY...AS THIS IS THE MOST
LIKELY PART OF THE REGION TO SEE ADDITIONAL HEAVY RAIN ON TOP OF
THE 1.5 TO 2.5 INCHES THAT HAS ALREADY FALLEN THERE OVER THE PAST
24 HOURS. WHILE CONFIDENCE IS SOMEWHAT LOW IN THE FORECASTED
PRECIPITATION TOTALS OVER THE NEXT 24 HOURS...IT SEEMS THAT AT
LEAST MINOR URBAN/SMALL STREAM FLOODING IS LIKELY THROUGH TOMORROW
MORNING ACROSS MENDOCINO COUNTY...WITH THE POTENTIAL FOR MORE
SIGNIFICANT FLOODING SHOULD THE HIGHER PRECIPITATION TOTALS
VERIFY. THIS WILL ALSO CAUSE MAIN STEM RIVERS TO RISE
QUICKLY...PARTICULARLY THE NAVARRO WHICH IS STILL FORECAST TO
CREST WELL ABOVE FLOOD STAGE TOMORROW MORNING THROUGH TOMORROW
NIGHT. AS A RESULT OF THESE THREATS...AN AREAL FLOOD WATCH HAS
BEEN ISSUED FOR MENDOCINO COUNTY IN ADDITION TO A RIVER FLOOD
WARNING FOR THE NAVARRO RIVER. OUTSIDE OF MENDOCINO COUNTY...RAIN
IS EXPECTED TO BE LESS INTENSE AND FLOODING IS NOT EXPECTED TO
BECOME A MAJOR CONCERN. HEAVY RAIN IS EXPECTED TO TAPER OFF
TOMORROW AFTERNOON...AND WILL BE FOLLOWED BY A PERIOD OF SCATTERED
SHOWERS THAT WILL LAST THROUGH THE EVENING.

THIS ACTIVE PATTERN WILL CONTINUE THROUGH THE WEEKEND...AS A
QUICK SUCCESSION OF STORM SYSTEMS WILL BRING ADDITIONAL ROUNDS OF
HEAVY RAIN AND GUSTY WINDS TO THE AREA EARLY SATURDAY AND MID DAY
SUNDAY...WITH NUMEROUS SHOWERS IN BETWEEN THE TWO SYSTEMS. THESE
STORMS WILL BE FOCUSED A BIT FARTHER NORTH THAN TODAYS STORM...BUT
THE COMBINATION OF THE TOTAL FORECASTED ACCUMULATIONS AND THE
BRIEF PERIOD BETWEEN THESE TWO STORMS WILL CAUSE MAIN STEM RIVERS
TO RISE QUICKLY AND REMAIN IN AN ELEVATED STATE THROUGH MONDAY. IN
ADDITION...MINOR URBAN AND SMALL STREAM FLOODING WILL BE POSSIBLE
IN PLACES AS WELL...PARTICULARLY ON SUNDAY. AND...IN ADDITION TO
THE RAIN...SNOW LEVELS WILL FLUCTUATE BETWEEN 5000 AND 3000 FEET
AS THESE STORMS PASS...WITH THE LOWEST SNOW LEVELS OCCURRING
FOLLOWING THE COLD FRONT PASSAGE LATE SUNDAY. GIVEN THAT SHOWERS
WILL LIKELY PERSIST THROUGH MONDAY...SOME LIGHT SNOW MAY REACH
DOWN TO A FEW OF OUR HIGH ELEVATION PASSES...WHILE THE HIGHER
PEAKS WILL LIKELY SEE SEVERAL INCHES OF ACCUMULATIONS THROUGH THE
WHOLE EVENT. /BRC

.LONG RANGE...TUESDAY THROUGH THURSDAY...LINGERING RAIN SHOWERS
ON TUESDAY ACROSS DEL NORTE COUNTY. OTHERWISE EXPECT DRY CONDITIONS
ACROSS THE CWA AS AN UPPER LEVEL RIDGE BUILDS OVER THE WEST COAST.
OVERNIGHT LOW TEMPERATURES COULD BECOME QUITE COOL TUESDAY MORNING
WITH THE SNOW LEVEL NEAR 3500 FEET. IF CLOUDS DISSIPATE...FROST WILL
BE A CONCERN IN THE INTERIOR MENDOCINO COUNTY VALLEYS TUESDAY
MORNING. WITH THE UPPER LEVEL RIDGE HOLDING OVER THE REGION...A
BREAK FROM THE RAIN AND A WARMING TREND TO BEGIN ON WEDNESDAY WITH
POSSIBLE OFFSHORE FLOW DEVELOPING.

&&

.AVIATION...RAIN WILL RETURN TO NORTHWEST CALIFORNIA THIS EVENING
FROM SOUTH TO NORTH AS THE PRIOR COLD FRONT COMBINES WITH A NEW
DISTURBANCE COMING OFF OF THE PACIFIC OCEAN. CIGS AND VIS ARE
EXPECTED TO DROP INTO MVFR TO IFR WITH THE ONSET OF RAIN AND THEN
CONTINUE THROUGH THE OVERNIGHT. LIFR CONDITIONS ARE NOT OUT OF THE
QUESTION FOR WHEN THE HEAVIEST RAIN FALLS...BETWEEN 06Z AND
18Z...BUT I THINK THAT THOSE CONDITIONS WOULD BE CONFINED TO
MENDOCINO AND HUMBOLDT COUNTIES...PERHAPS EVEN TRINITY COUNTY.
CONDITIONS SHOULD BOUNCE BACK TO VFR/MVFR FOR THE AFTERNOON AND
EARLY EVENING BEFORE THE NEXT SYSTEM ARRIVES SATURDAY NIGHT. KAR

&&

.MARINE...LIGHT TO MODERATE WINDS WILL PREVAIL ACROSS THE WATERS
TONIGHT THROUGH FRIDAY. THE SEAS WILL CONTINUE TO GRADUALLY
SUBSIDE THROUGH FRIDAY. A STRONG COLD FRONT WILL MOVE THROUGH THE
REGION FRIDAY NIGHT AND EARLY SATURDAY MORNING. THE WINDS AND SEAS
WILL INCREASE AS THE FRONT APPROACHES AND MOVES ACROSS THE WATERS.
SMALL CRAFT ADVISORIES WILL REMAIN IN EFFECT ACROSS THE NORTHERN
NEAR SHORE WATERS THROUGH FRIDAY MORNING AND ACROSS THE SOUTHERN
NEAR SHORE WATERS THROUGH FRIDAY AFTERNOON. SMALL CRAFT ADVISORIES
ARE CURRENTLY IN EFFECT ACROSS THE OUTER WATERS THROUGH THIS
WEEKEND. HOWEVER AS THE STRONG COLD FRONT APPROACHES AND MOVES
ACROSS THE WATERS FRIDAY NIGHT AND SATURDAY THE SMALL CRAFT
ADVISORIES WILL LIKELY BE UPGRADED TO A GALE WARNING DUE TO GALE
FORCE GUSTS ACROSS THE NORTHERN OUTER WATERS BEGINNING FRIDAY
NIGHT AND ACROSS THE SOUTHERN OUTER WATERS BEGINNING SATURDAY
MORNING. THE GALE WARNING POTENTIALLY COULD REMAIN IN EFFECT
THROUGH SUNDAY. SMALL CRAFT ADVISORIES WILL BE NECESSARY ACROSS
THE NEAR SHORE WATERS SATURDAY THROUGH MONDAY DUE TO INCREASING
WINDS AND/OR SEAS.

&&

.HYDROLOGY...RAIN TONIGHT THROUGH SUNDAY WILL RESULT IN HIGH FLOWS
ON THE MAIN STEM RIVERS ACROSS NORTHWEST CALIFORNIA. THE GREATEST
CHANCE FOR RIVER FLOODING WILL OCCUR ON FRIDAY INTO SATURDAY IN
MENDOCINO COUNTY AS RAIN FALLS ON ALREADY SATURATED SOILS. BOTH
THE NAVARRO AND RUSSIAN RIVERS WILL RISE SHARPLY WITH THE NAVARRO
LIKELY REACHING FLOOD STAGE AND THE RUSSIAN LIKELY REACHING
MONITOR STAGE. ADDITIONAL RAINFALL OVER THE WEEKEND FURTHER NORTH
MAY ALSO RESULT IN THE EEL RIVER AT FERNBRIDGE...THE MAD RIVER AT
ARCATA...AND THE VAN DUZEN RIVER AT BRIDGEVILLE REACHING MONITOR
STAGES. STAY TUNED FOR FORECAST UPDATES.
