AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
323 PM PDT THU MAY 23 2013

.SYNOPSIS...
COOL AIR WILL CONTINUE TO FLOW INTO NORTHWEST CALIFORNIA THROUGH
THURSDAY. INTERIOR AREAS WILL NOT BE AS COLD TONIGHT. A LITTLE LIGHT
RAIN WILL BE POSSIBLE AT EARLY FRIDAY MORNING AND AGAIN SATURDAY
NIGHT NORTH OF TRINIDAD OTHERWISE IT IS LOOKING LIKE A DRY WEEKEND. A
MORE WIDESPREAD RAIN WILL ARRIVE MONDAY.

&&

.DISCUSSION...
TEMPERATURES ON AVERAGE ARE RUNNING 5 TO 10 DEGREES WARMER THAN
YESTERDAY INLAND, AND CONDITIONS ARE A BIT MILDER ON THE COAST AS
WELL. SFC HIGH PRESSURE RIDGING HAS ACTUALLY SHIFTED NORTHWARD INTO
SRN OREGON TODAY AS THE UPPER LOW CENTERED OVER WASHINGTON STATE
CONTINUES TO FILL. THIS HAS HELPED PROMOTE MOSTLY SUNNY SKIES ALL
THE WAY UP THE COAST, JUST ABOUT TO CAPE BLANCO. THE NORTH COAST
INTERIOR HAS SEEN SOME CUMULUS BUILD-UPS OVER THE HIGHER TERRAIN
WITH DAYTIME HEATING. SUSPECT THERE COULD STILL BE AN ISOLATED
SHOWER OVER THE SISKIYOUS OF ERN DEL NORTE OR ERN HUMBOLDT COUNTY
EARLY THIS EVENING. KBHX RADAR HAS NOT PICKED UP ANYTHING...SO IF
THERE ARE ANY WEAK SHOWERS OUT THERE NOW, THEY ARE BEING OVERSHOT
BECAUSE THE TOPS ARE SO LOW.

THE FINAL SHORTWAVE ROUNDING THE UPPER LOW WILL APPROACH THE NORTH
COAST THIS EVENING BUT AS THE LOW CONTINUES TO FILL, ANY
PRECIPITATION WILL NEED TO BE FORCED IN THE SHALLOW MOISTURE AND
INSTABILITY WITH ONSHORE FLOW WITHIN A FEW THOUSAND FEET OF THE
SURFACE. AS THE BOUNDARY LAYER STABILIZES OVERNIGHT NEAR THE COAST
SUSPECT THAT ANYTHING THAT DOES DEVELOP FROM PERHAPS ORICK NORTHWARD
MAY BE IN THE FORM OF LIGHT DRIZZLE. THIS COULD LINGER INTO EARLY
FRIDAY MORNING...OTHERWISE FRIDAY IS LOOKING LIKE ANOTHER MOSTLY
SUNNY AND DRY DAY WITH SLIGHTLY WARMER TEMPERATURES. THAT SAID, IT
WILL STILL BE COLD ACROSS THE INTERIOR TONIGHT, THOUGH NOT AS COLD
AS LAST NIGHT. ISSUED A FROST ADVISORY FOR TRINITY COUNTY. GUIDANCE
INDICATES THAT TEMPERATURES SHOULD BE AT LEAST COLD ENOUGH FOR FROST
THERE...AND PERHAPS IN THE DEEPER VALLEYS OF NORTHERN MENDOCINO AND
EASTERN HUMBOLDT COUNTY AS WELL.

THE WEEKEND GENERALLY LOOKS DRY ALTHOUGH THERE WILL BE A PESKY
TROUGH MOVING THROUGH SATURDAY NIGHT INTO SUNDAY MORNING. THINKING
THERE WILL BE ENOUGH SUBSIDENCE AND DRY AIR IN THE LOWER LEVELS TO
LIMIT SHOWERS TO NEAR THE OREGON BORDER. BETTER SHOT AT ISOLATED
SHOWERS AND MAYBE EVEN A RUMBLE OF THUNDER WILL BE WITH ANY
BUILD-UPS OVER THE SISKIYOUS OR YOLLA BOLLYS.

A MORE DEFINED STORM SYSTEM WILL APPROACH SUNDAY NIGHT. MODELS ARE
CONVERGING ON A PERIOD OF WIDESPREAD RAINFALL...PERHAPS OVER A
HALF-INCH...CENTERED ON MONDAY. NOT IDEAL BARBECUE WEATHER
UNFORTUNATELY.

&&

.AVIATION...VFR CONDITIONS, CLEAR TO PARTLY CLOUDY SKIES AND LIGHT
TO MODERATE WINDS WILL CONTINUE AT KCEC, KACV AND KUKI THROUGH THE
EARLY EVENING. MODERATE TO MODERATE AND GUSTY WINDS WILL CONTINUE
THROUGH THE EARLY EVENING NEAR THE COAST THEN LIGHT TO CALM WINDS
WILL PREVAIL ACROSS KCEC, KACV AND KUKI OVERNIGHT TONIGHT AND EARLY
FRIDAY MORNING. CLOUDINESS WILL INCREASE OVERNIGHT AT KCEC AND KACV
REDUCING CEILINGS, HOWEVER CEILINGS WILL REMAIN AT VFR CONDITIONS.

&&

.MARINE...THE PRESSURE GRADIENT WILL CONTINUE TO RELAX AND
SUBSEQUENTLY THE WINDS AND SEAS WILL GRADUALLY DIMINISH ACROSS THE
WATERS THROUGH THIS WEEKEND. LIGHT TO MODERATE WINDS AND MODERATE
SEAS WILL PREVAIL ACROSS THE WATERS FRIDAY THROUGH EARLY NEXT WEEK.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...FROST ADVISORY FROM 2 AM TO 8 AM PDT FRIDAY CAZ004.

NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
