AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
1024 AM PDT SAT MAR 14 2015

.SYNOPSIS...A FRONT WILL BRING LIGHT RAIN SHOWERS TO AREAS NORTH
OF CAPE MENDOCINO TONIGHT TODAY AND THEN MORE WIDESPREAD RAIN TO
MUCH OF NORTHWEST CALIFORNIA ON SUNDAY INTO SUNDAY NIGHT.
LINGERING SHOWERS WILL CONTINUE THROUGH AT LEAST MID WEEK.

&&

.UPDATE...MORNING RADAR SHOWS SHOWERS FURTHER SOUTH THAN EXPECTED.
DESPITE SURFACE OBSERVATIONS SHOWING VERY LITTLE, IF ANY,
ACCUMULATIONS, DECIDED TO BUMP UP POPS ACROSS MENDOCINO COUNTY AND
INCLUDE ISOLATED SPRINKLES IN THE FORECAST TO REFLECT THE
POTENTIAL.

&&

.PREV DISCUSSION......ISSUED AT 250 AM PDT...

DISCUSSION...A WARM FRONT CONTINUES TO MOVE THROUGH NORTHWEST
CALIFORNIA THIS MORNING WITH ISOLATED TO SCATTERED SHOWERS MOVING
OVER THE REGION FROM SOUTHWEST TO NORTHEAST. THESE SHOWERS MAY
CONTINUE THROUGH THE DAY TODAY PRIMARILY NORTH OF MENDOCINO COUNTY
AS THE WARM FRONT MOVES NORTH INTO OREGON. MODELS CONTINUE TO
INDICATE THAT A BAND OF STRATIFORM RAIN WILL DEVELOP OVER
NORTHWEST CALIFORNIA TONIGHT AS A LOW PRESSURE SYSTEM BEGINS TO
STRENGTHEN OFF THE COAST. THERE ARE SIGNIFICANT MODEL DIFFERENCES
WITH THE ECMWF INDICATING MUCH LIGHTER PRECIPITATION THAN THE
GFS/NAM/SREF DURING THE OVERNIGHT...BUT THEY ARE ALL CONSISTENT
WITH THE PRECIPITATION DEVELOPING OVER THE NORTHERN HALF OF THE
AREA AND THEN SPREADING NORTH INTO OREGON IN THE MORNING HOURS OF
SUNDAY. BY THE AFTERNOON THE LOW PRESSURE SYSTEM WILL SLIDE UP THE
COAST AND LIKELY BEGIN TO MOVE TOWARD THE OREGON/CALIFORNIA BORDER
BRINGING ANOTHER PERIOD OF MODERATE TO AT TIMES HEAVY RAIN SUNDAY
EVENING/NIGHT. THE GFS HAS SLOWED DOWN SIGNIFICANTLY WITH THE
APPROACH OF THE LOW PRESSURE SYSTEM AND ACTUALLY WEAKENS IT AS IT
REACHES THE COAST RESULTING IN MUCH LESS RAIN THAN PREVIOUS RUNS.
FOR NOW WILL STICK WITH THE ONGOING FORECAST...MUCH CLOSER TO THE
ECMWF...OF RAIN OVERNIGHT FOR AREAS PRIMARILY NORTH OF WILLITS.
THERE IS NOW A REAL PROBABILITY THAT LOCATIONS SOUTH OF WILLITS
MAY SEE VERY LITTLE RAINFALL THROUGH THIS ENTIRE EVENT WITH THE
BOUNDARY HANGING UP NORTH OF CAPE MENDOCINO.

THE FRONT WILL SAG OVER THE COUNTY WARNING AREA ON MONDAY LEAVING A
MODERATELY HIGH 0-6 KM SHEAR/LOW CAPE ENVIRONMENT ACROSS THE
INTERIOR. THIS MAY ALLOW SHOWERS TO REINTENSIFY IN THE AFTERNOON
OVER THE MOUNTAINS AND POSSIBLY SUPPORT AN ISOLATED THUNDERSTORM.
SPC PERFECT PROG INDICATES A 10-15 PERCENT CHANCE OF A LIGHTNING
STRIKE MOSTLY JUST NORTH OF TRINITY COUNTY. WITH THE CHANCES OF
THUNDERSTORMS REMAINING LOW...WILL CONTINUE TO ONLY MENTION
SHOWERS IN THE FORECAST BUT THIS WILL HAVE TO BE LOOKED AT OVER
THE NEXT FEW FORECAST UPDATES.

THE FRONT WILL DISSIPATE MONDAY INTO TUESDAY BUT A PIECE OF UPPER
LEVEL ENERGY MAY BE LEFT BEHIND WITH LINGERING MOISTURE IN PLACE
OVER CALIFORNIA. WITH COOL AIR ALOFT...INSTABILITY AND MOISTURE MAY
BE JUST ENOUGH TO TRIGGER AFTERNOON MOUNTAIN SHOWERS TUESDAY THROUGH
THURSDAY AFTERNOONS. THE BEST CHANCE FOR SHOWERS...AND POSSIBLY A
THUNDERSTORM...MAY BE WEDNESDAY AFTERNOON IF THE GFS SOLUTION OF A
WEAK SHORTWAVE MOVING OVERHEAD IS CORRECT. AGAIN...HAVE KEPT THE
FORECAST AS SHOWERS FOR NOW CONSIDERING FORECASTING SHORTWAVE
PASSAGES 5 DAYS OUT IS NEVER EASY.

UPPER LEVEL RIDGING WILL BUILD IN OVER THE WEST COAST THURSDAY
LEADING TO BETTER CAPPING AND LIKELY LESS POTENTIAL FOR
THUNDERSTORMS BUT STILL THE POTENTIAL FOR SHOWERS ACROSS THE
INTERIOR. BOTH THE GFS AND ECMWF HAVE ANOTHER COLD FRONT APPROACHING
THE COAST FRIDAY OR FRIDAY NIGHT BUT TIMING WILL LIKELY CHANGE OVER
THE NEXT SEVERAL MODEL RUNS SO HAVE KEPT CHANCES FOR PRECIPITATION
NEAR CLIMATOLOGY. /RPA

AVIATION...STRONGER MIXING AND GENTLE SOUTHERLY WINDS WILL LIKELY
MAINTAIN VFR CIGS AND GOOD VSBYS THROUGH THE DAY TODAY. LIGHT EAST
FLOW TONIGHT WILL MAINTAIN VFR CONDITIONS THROUGH EARLY SUNDAY.

MARINE...BUOYS WERE REPORTING SEAS AROUND 5 FT AT 10 SECONDS EARLY
THIS MORNING UNDER A PREDOMINANTLY LIGHT SOUTHERLY WIND FIELD.
MOST ALL THE WAVE ENERGY HAS BEEN COMING FROM THE WEST. THAT WILL
CHANGE ON SUNDAY AS SOUTHERLY WINDS AND WIND WAVES INCREASE AS A
WEAK LOW PRESSURE SYSTEM APPROACHES THE AREA. HIGH PRESSURE SHOULD
BUILD TOWARD THE COAST EARLY NEXT WEEK AND BRING A RETURN OF
GENTLE NORTHERLY WINDS.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
