AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
432 AM PST FRI MAR 4 2016

.SYNOPSIS...A WARM FRONT WILL BRING ANOTHER ROUND OF LIGHT TO
MODERATE RAIN AND GUSTY WINDS BY TONIGHT. A POTENT COLD FRONT
WILL DEVELOP ON SATURDAY AND PRODUCE HEAVY RAIN AND STRONG WINDS.
COOLER AIR BEHIND THE FRONT WILL RESULT IN PERIODS SHOWERS AND
HIGH ELEVATION SNOW SHOWERS ON SUNDAY.

&&

.DISCUSSION...WARM ADVECTION AND SOUTHERLY FLOW HAVE STARTED TO
INCREASE OVER THE SOUTHERN PORTION OF THE AREA THIS MORNING AHEAD
OF THE SYSTEM APPROACHING THE AREA. THIS IS BRINGING A FEW LIGHT
RAIN SHOWERS TO SOUTHERN MENDOCINO COUNTY THIS MORNING. WINDS HAVE
STARTED TO GUST TO 15 TO 25 MPH OVER THE HILLS AS OF 4AM. THIS
MORNING IS EXPECTED TO MAINLY DRY...WARM AND WINDY. THIS AFTERNOON
THE SHOWERS IN MENDOCINO COUNTY WILL GRADUALLY INCREASE IN
COVERAGE THIS MORNING...BUT WILL BE STRONGLY DRIVEN BY THE
TERRAIN INFLUENCES. THIS AFTERNOON THESE WILL START TO BECOME MORE
NUMEROUS ACROSS THE AREA.

THIS EVENING THE FIRST WAVE OF HEAVIER PRECIP STARTS TO MOVE
THROUGH INTO THE AREA. THE CURRENT GFS RUN SHOWS THIS HEAVIER RAIN
PERSISTING FROM FRIDAY EVENING THROUGH SATURDAY EVENING. THERE MAY
BE SOME BRIEF BREAKS...BUT GENERALLY IT LOOKS TO PERSIST. THIS
STILL LOOKS LIKE IT MAY CAUSE SOME FLOODING...SO THE AREAL FLOOD
WATCH LOOKS ON TRACK. RAINFALL AMOUNTS IN THIS 24 HOURS ARE EXPECTED
TO BE AROUND 2 TO 3 INCHES WITH LOCAL AMOUNTS UP TO 5 INCHES IN
THE FAVORED AREAS. FOR MORE DETAILS ON THE FLOODING SEE THE HYDRO
SECTION.

SATURDAY EVENING ONCE THE MAIN FRONTAL BOUNDARY MOVES THROUGH THE
SHOWERS WILL PICK UP. THERE IS QUITE A BIT OF COLD BIT ALOFT SO AN
ISOLATED THUNDERSTORM IS POSSIBLE. THE BEST CHANCE IS ALONG THE
COAST WHERE WE HAVE THEM IN THE FORECAST...BUT ITS HARD TO RULE
ONE OUT FARTHER INLAND ON SUNDAY AFTERNOON. SNOW LEVELS WILL DROP
BEHIND THE FRONT AS WELL. CURRENT MODELS ARE INDICATING SNOW
LEVELS WILL BOTTOM OUT AROUND 3000 TO 3500 FEET. THIS WOULD BRING
VERY LITTLE ACCUMULATING SNOW TO THE PASSES ON HWY 299...BUT
WOULD BRING SOME TO THE PASSES ON HWY 3 AND 36. AT THIS POINT IT
LOOKS LIKE AMOUNTS WILL BE IN THE ADVISORY LEVEL RANGE (2 TO 5
INCHES IN 12 HOURS) SO HAVE HELD OFF ON ISSUING ANYTHING. THE MAIN
CONCERN IS HOW LOW THE SNOW LEVELS WILL GET...IT IS POSSIBLE THEY
WILL BE LOWER THAN EXPECTED IN THE HEAVIER SHOWERS BRINGING SOME
MORE IMPACTS TO HWY 299.

THE UPPER TROUGH WILL SWING THROUGH ON MONDAY...RESULTING IN
SLIGHT WARMING ALOFT AND INCREASING STABILITY BY MON NIGHT.
SHOWERS WILL DIMINISH AND POPS MAY NEED TO BE LOWERED FURTHER. THE
LATEST GFS AND ECMWF CONTINUE TO INDICATE A WARM FRONT APPROACHING
ON TUE FOR MORE LIGHT TO MODERATE RAIN BY TUE NIGHT. THERE ARE
STILL SOME TIMING DIFFERENCES WITH THE ECMWF FASTER THAN THE GFS.

WEDNESDAY THE GFS LIFTS THIS FRONT BACK TO THE NORTH DRYING US OUT
WHILE THE ECMWF KEEPS THE AREA MUCH WETTER. THERE IS BETTER
AGREEMENT ON FRONTAL PASSAGE WITH BOTH MODELS PUSHING IT THROUGH
EARLY THURSDAY MORNING. LATE IN THE WEAK ANOTHER SYSTEM APPROACHES
THE AREA BRINGING ADDITIONAL RAIN AND WIND. MKK

&&

.AVIATION...VFR CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS
WILL CONTINUE AT KCEC AND KACV THROUGH THE EARLY MORNING. THE
WINDS WILL BECOME MODERATE AND GUSTY THIS AFTERNOON THROUGH
TONIGHT AS A COLD FRONT MOVES THROUGH THE REGION. SHOWERS WILL
MOVE THROUGH THE AREA LATE THIS AFTERNOON THROUGH SATURDAY
INCREASING CLOUDINESS AND REDUCING CEILINGS AND/OR VISIBILITIES TO
MVFR AND TEMPORARY IFR CONDITIONS AT KCEC AND KACV. VFR TO MVFR
CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL CONTINUE AT
KUKI TODAY. SHOWERS WILL MOVE THROUGH THE AREA REDUCING CEILINGS
AND/OR VISIBILITIES THIS AFTERNOON THROUGH SATURDAY AT KUKI. WINDS
WILL BECOME MODERATE AND GUSTY THIS AFTERNOON AND TONIGHT AT KUKI.

&&

.MARINE...AN APPROACHING COLD FRONT COMBINED WITH A STRONG LOW
PRESSURE SYSTEM WEST OF THE NORTHWESTERN UNITED STATES AND
SOUTHWESTERN CANADA WILL INCREASE THE WINDS AND STEEP SEAS ACROSS
ALL THE WATERS TODAY AND TONIGHT. WIND GUSTS TO GALE FORCE WILL
OCCUR TODAY ACROSS THE NORTHERN WATERS AND BY TONIGHT AND EARLY
SATURDAY MORNING ACROSS THE SOUTHERN WATERS. THEREFORE SMALL CRAFT
ADVISORIES ACROSS THE NORTHERN WATERS WILL BE REPLACED BY A GALE
WARNING ACROSS THE NORTHERN OUTER WATERS THIS MORNING AND A GALE
WARNING ACROSS THE NORTHERN NEAR SHORE WATERS THIS AFTERNOON. THE
SMALL CRAFT ADVISORIES ACROSS THE SOUTHERN WATERS WILL BE REPLACED
BY A GALE WARNING ACROSS THE SOUTHERN OUTER WATERS TONIGHT AND A

PACIFIC OCEAN AND COLD FRONTS APPROACHING AND MOVING THROUGH THE
REGION AT TIMES THROUGH EARLY NEXT WEEK WILL MAINTAIN ELEVATED
SEAS ACROSS THE WATERS THROUGH NEXT TUESDAY. THEREFORE ONCE THE
WINDS GRADUALLY DIMINISH SATURDAY NIGHT AND SUNDAY SMALL CRAFT
