AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
415 AM PST SUN FEB 9 2014

.SYNOPSIS...RAIN WILL CONTINUE TO IMPACT MOST AREAS OF NW
CALIFORNIA THIS MORNING AS LOW PRESSURE MOVES TOWARD CAPE
MENDOCINO. THE HEAVIEST RAIN WILL BE ACROSS MENDOCINO COUNTY WITH
RAIN INTENSITY DIMINISHING FARTHER NORTH. A BUILDING RIDGE IS
FORECAST TO BRING DRYING WEATHER MONDAY AND TUESDAY.

&&

.DISCUSSION...MORNING WATER VAPOR SATELLITE IMAGERY CONTINUES TO
SHOW A STEADY STREAM OF MOISTURE PUSHING INTO NW CALIFORNIA FROM
THE SW. A FRONTAL WAVE APPEARS TO BE DEVELOPING ON THIS BOUNDARY
NEAR 38N137W WITH DECENT SURFACE CYCLOGENESIS. MODELS ARE
INDICATING A CLOSED SURFACE LOW DEVELOPING UNDER AN UPPER
SHORTWAVE AND MOVING TOWARD THE MENDOCINO/HUMBOLDT COUNTY LINE.
THIS WILL BRING CONTINUED ONSHORE FLOW AND A STRONG SUB TROPICAL
MOISTURE TAP TO MENDOCINO COUNTY. HAVE KEPT POPS AT OR NEAR 100
PERCENT FOR MENDOCINO THIS MORNING WITH FORECAST QPF TOTALS AROUND
A HALF TO THREE QUARTERS OF AN INCH. UPSLOPING MAY CAUSE SLIGHTLY
HIGHER TOTALS IN SOME AREAS. SURFACE WINDS ACROSS HUMBOLDT,
TRINITY, AND DEL NORTE SHOULD BE OUT OF THE SOUTH AND SOUTHEAST
THIS MORNING WITH THE LOW MOVING INLAND OVER NORTHERN MENDOCINO.
KEPT POPS LOWER ACROSS THESE NORTHERN AREAS DUE TO THE LACK OF THE
ONSHORE MOISTURE STREAM. HOWEVER, DID NEED TO KEEP IN MIND THE
MOISTURE WRAP AROUND THE LOW AT MID LEVELS AND MARGINAL
DESTABILIZATION. THIS SHOULD BRING SOME SHOWERS TO THE NORTHERN
PORTIONS OF THE CWA AS THE LOW SLIDES THROUGH THIS MORNING. MODELS
ARE SUGGESTING THE SLIGHTEST CHANCE OF A THUNDERSTORM OVER
MENDOCINO COUNTY THIS EVENING IN THE WAKE OF THE LOW DUE TO
ENHANCED MID LEVEL COOLING, DECENT OMEGA VALUES, AND STRONG UPPER
LEVEL WINDS. SPC HAS MENDOCINO INSIDE THE GENERAL THUNDER LINE BUT
SEEM SKEPTICAL AS TO TSTMS ACTUALLY OCCURRING OVER OUR AREA. AS
SUCH, HAVE OPTED NOT TO INCLUDE ANY CHANCE OF TSTMS IN THE
FORECAST. THE DAY SHIFT MAY NEED TO UPDATE THE FORECAST TO INCLUDE
TSTMS IF THEY BEGIN TO SHOW ON LIGHTNING DETECTION. AFTER THIS LOW
MOVES OUT TO THE EAST SHOWERS WILL DIMINISH OVERNIGHT.

MONDAY AND TUESDAY WILL SEE A DRYING TREND ACROSS THE REGION AS
HEIGHTS BUILD IN RESPONSE TO A RIDGE NOSING IN FROM THE SW. THE
NEXT SHOT AT PRECIPITATION IS WEDNESDAY AS A WARM FRONT CLIPS THE
NORTHERN PORTIONS OF THE CWA, FOLLOWED BY A COLD FRONT SINKING IN
FROM THE NORTH. WINDS AHEAD OF THIS WARM FRONT COULD BECOME STRONG
ACROSS COASTAL DEL NORTE COUNTY AND ALONG COASTALLY INFLUENCED
RIDGES. THE GFS AND NAM ARE SHOWING 925MB WINDS IN THE 40 TO 50 KT
RANGE. THESE WINDS SHOULD NOT HAVE AN ISSUE MIXING DOWN TO THE
SURFACE IN GUSTS IN A WELL COUPLED ATMOSPHERE.

THE LAST HALF OF THE WEEK WILL CONTINUE WITH UNSETTLED WEATHER AS
A BROAD UPPER TROUGH OVER THE GULF OF ALASKA SWINGS UPPER LEVEL
DISTURBANCES TOWARD THE WEST COAST. AT THIS POINT IT LOOKS LIKE
THE FOCUS OF THE MOISTURE WILL REMAIN FROM CAPE MENDOCINO
NORTHWARD, HOWEVER CONFIDENCE IN THE LONG RANGE FORECAST IS LOW.

FOR THE FORECAST...MADE SOME TIMING CHANGES TO THE POPS DURING MID
WEEK AND WENT WITH CLIMO POPS AT THE END OF THE FORECAST. KEPT
TEMPS NEAR NORMAL FOR THE WEEK, GENERALLY USING CONSALL. KEPT THE
SNOW LEVEL UP WITH SIGNIFICANT WARM ALOFT OVER THE AREA. BFG

&&

.AVIATION...EXPECT LARGE FLUCTUATIONS ACROSS NORTHWEST CALIFORNIA TODAY
RANGING FROM MOSTLY MVFR TO TEMPO LIFR IN THE HEAVIER RAIN BANDS.

&&

.MARINE...WINDS AND SEAS WILL CONTINUE TO SUBSIDE THIS MORNING AS AN
APPROACHING LOW PRESSURE SYSTEM ALLOWS THE PRESSURE GRADIENT TO
WEAKEN. THOUGH, THE MOST INCLEMENT WEATHER IS EXPECTED TO BE SOUTH
OF OUR WATERS. LOWER WINDS AND SEAS WILL PERSIST THROUGH MONDAY WITH
LIGHT SPLIT FLOW ACROSS THE WATERS. SOUTHERLY CONDITIONS WILL BEGIN
BUILDING ON TUESDAY AS MULTIPLE SYSTEMS START MOVING INTO THE AREA,
CONTINUING THROUGH THE END OF THE WEEK.

&&

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