AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE EUREKA CA
1036 PM PDT MON MAR 31 2014

.SYNOPSIS...
SHOWERS WILL CONTINUE TUESDAY WITH THE MOST NUMEROUS ACTIVITY SOUTH
OF CAPE MENDOCINO. A RUMBLE OF THUNDER OR SOME SMALL HAIL CANNOT BE
RULED OUT. WEDNESDAY WILL BE A DRY DAY WITH SOME SUNSHINE BEFORE A
WEAK FRONT MOVES THROUGH WITH SOME SHOWERS ON THURSDAY.

&&

.DISCUSSION...
IN THE WAKE OF AN OCCLUDED FRONT, DRIER AND COOLER AIR WILL FILTER
IN TONIGHT. SKIES HAVE CLEARED SUBSTANTIALLY OFFSHORE AS SHORTWAVE
RIDGING ALLOWS FOR SOME SUBSIDENCE, AND WE EXPECT THIS TO CONTINUE
TO PUSH ONSHORE THIS EVENING. BEHIND THE MAIN BAND OF RAIN
ASSOCIATED WITH THE FRONT, CLOUDS AND A FEW SHOWERS WILL LINGER
MAINLY ACROSS INLAND AREAS, AS LAPSE RATES INCREASE WITH THE COLDER
AIR MOVING IN ALOFT. HAVE ONLY RECEIVED A FEW SNOW REPORTS TODAY
ABOVE 3500 FT, WITH THE BEST ESTIMATED AVERAGE ACCUMULATION BEING 3
TO 5 INCHES WITH THE HIGHEST AMOUNTS ABOVE 4000 FT. ANOTHER 1 TO 3
INCHES BEFORE THINGS DRY OUT TONIGHT WILL BRING US NEAR THE WARNING
CRITERIA. ALREADY MOVED THE END TIMES 3 TO 6 HOURS EARLIER...BUT THE
EVENING SHIFT MAY NEED TO CANCEL EARLY OR DOWNGRADE THE WARNING FOR
NORTH COAST INTERIOR AND TRINITY TO AN ADVISORY...AS PRECIPITATION
IS QUICKLY ENDING FROM WEST TO EAST WITH MINIMAL LINGERING SHOWER
ACTIVITY. IMPACTS HAVE BEEN MINIMAL AS ROAD SURFACES ARE MILD ENOUGH
TO LIMIT ACCUMULATIONS...AND NO CHAIN RESTRICTIONS HAVE BEEN
REPORTED EVEN OVER THE HIGHER PASSES, SUCH AS SOUTH FORK MOUNTAIN
AND HAYFORK SUMMIT.

ANOTHER WINTER WEATHER ADVISORY MAY BE NECESSARY FOR TOMORROW,
MAINLY FOR INTERIOR MENDOCINO COUNTY ABOVE 3500 FEET, AS ANOTHER
SURGE OF MOISTURE AND UPPER-LEVEL DIVERGENCE MOVES IN AHEAD OF THE
UPPER LOW. SNOW HAS BEEN REPORTED AS LOW AS 2500 FEET MIXED IN WITH
THE RAIN, AND THAT WILL CONTINUE TO BE THE CASE THROUGH TUESDAY WITH
THE HEAVIER SHOWER ACTIVITY. THE OTHER FORECAST CONCERN WILL BE ANY
RUMBLES OF THUNDER OR SMALL HAIL THAT OCCURS WITH THE HEAVIER
SHOWERS. MOST UNSTABLE AIR AND THE BETTER FORCING WILL TRACK SOUTH
OF OUR AREA TOWARD THE BAY AREA, BUT STILL LEFT A SLIGHT CHANCE OF
THUNDER AND SMALL HAIL FOR THE ENTIRE CWA TUESDAY. IMPACTS WILL BE
MINIMAL WITH MORE RAIN THAN PURELY HAIL EXPECTED. THE BEST SHOT AT
ANY ACCUMULATING SMALL HAIL WILL BE OVER COASTAL MENDOCINO COUNTY,
AND THE OVERNIGHT CREW AND TOMORROWS DAY SHIFT WILL NEED TO MONITOR
CLOSELY.

OTHERWISE SHOWER ACTIVITY TOMORROW WHICH WILL BE CONCENTRATED MOSTLY
OVER THE INTERIOR AND SOUTH OF CAPE MENDOCINO WILL TAPER OFF TUESDAY
NIGHT. SOME BREAKS OF SUNSHINE CAN BE EXPECTED ON TUESDAY WITH THE
CONVECTIVE ENVIRONMENT...PARTICULARLY NORTH OF CAPE MENDOCINO WHERE
THE AIRMASS WILL BE DRIER AND FORCING WILL BE LESS. WEDNESDAY WILL
BE THE NICEST DAY OF THE WEEK WITH DRY AND MOSTLY SUNNY WEATHER.
THURSDAY A WEAK FRONT WILL PASS BY WITH ISOLATED TO SCATTERED
SHOWERS, BUT RAINFALL AMOUNTS WILL BE LIGHT AND CARRY MINIMAL
IMPACT. MODELS DIVERGE ON HOW SLOWLY THE NORTH COAST WILL DRY OUT
FRIDAY AND SATURDAY, SO LEFT SLIGHT/LOW CHC POPS THERE. HIGHER
CONFIDENCE EXISTS FOR DRIER WEATHER SUNDAY INTO EARLY NEXT WEEK WITH
A HIGH AMPLITUDE RIDGE BUILDING IN. TEMPERATURES MAY WARM INTO THE
70S TO NEAR 80 INLAND IF CURRENT MODEL PROJECTIONS VERIFY. AAD

&&

.AVIATION...GUSTY SOUTH AND SOUTHEASTERLY WINDS ASSOCIATED WITH THE
PASSING FRONT WILL DECREASE OVER THE NEXT FEW HOURS AS THE FRONT
MOVES EAST. MVFR CONDITIONS ARE GIVING RISE VFR CONDITIONS ACROSS
THE AREA IN THE WAKE OF THE FRONT. A RELATIVE DRY AIR MASS BAND IS
MOVING INTO THE AREA BEHIND THE FRONT AND THIS SHOULD LEAD TO THESE
IMPROVED CONDITIONS LASTING TIL MIDNIGHT. EXPECT SOME SHOWERS AND
RELATED MVFR CONDITIONS IN THE LATE NIGHT AND MORNING AS THE UPPER
LEVEL CORE AND ASSOCIATED COLD UNSTABLE AREA MOVES OVER THE AREA.

&&

.MARINE...WINDS AND SHORT PERIOD SEAS ARE SUBSIDING IN THE WAKE
OF THE PASSING COLD FRONT. EXPECT SOME MARGINAL SQUALLS TO MOVE
OVER THE WATERS OVERNIGHT AS COLD UNSTABLE AIR BEHIND THE SYSTEM
PASSES OVER. OTHERWISE...A NEW LOW PRESSURE WILL APPROACH THE
REGION LATE TONIGHT INTO TUE MORNING. S AND SE WINDS WILL INCREASE
AGAIN...BUT NOT AS STRONG AS PREVIOUSLY SO HAVE PUT UP SCA. THE ENP
AND SWAN INDICATE WESTERLY SWELL BUILDING TONIGHT INTO TUE. THEN
BY MID WEEK SEAS WILL SLOWLY SUBSIDE.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...WINTER WEATHER ADVISORY UNTIL 8 PM PDT THIS EVENING ABOVE 3500
     FEET FOR THE CAZ076.

     WINTER STORM WARNING UNTIL 8 PM PDT THIS EVENING ABOVE 3500 FEET
