AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
439 AM PST THU MAR 7 2013

.SYNOPSIS...SCATTERED SHOWERS WILL CONTINUE TO SLOWLY DIMINISH
TODAY AND TONIGHT. A RIDGE OF HIGH PRESSURE WILL BRING A RETURN
TO DRY WEATHER BY FRIDAY AND INTO THE WEEKEND.

&&

.SHORT TERM...WATER VAPOR SHOWS AN UPPER LEVEL TROUGH OFF THE
COAST THIS MORNING. THIS CONTINUES TO BRING SCATTERED SHOWERS TO
MAINLY THE WATERS THIS MORNING WITH A FEW MAKING IT ONSHORE. A
STRONG VORT MAX IS CURRENTLY ROUNDING THE BOTTOM OF THE TROUGH.
MODELS SHOW THIS CONTINUING TO DIVE SOUTH AND REMAIN WELL
OFFSHORE. SOME WRAP AROUND MOISTURE STILL LOOKS TO MOVE OVER THE
AREA THIS AFTERNOON...MAINLY MENDOCINO COUNTY. THIS SHOULD BE
ENOUGH TO ENHANCE SHOWERS...ESPECIALLY WHERE IT INTERACTS WITH
TERRAIN. SOUNDING PROFILES DIDNT LOOK FAVORABLE ENOUGH TO PUT
THUNDERSTORMS IN THE FORECAST...HOWEVER IT IS HARD TO RULE OUT AN
ISOLATED STRIKE IN MENDOCINO COUNTY IN THE AFTERNOON. TONIGHT A
FROST ADVISORY MAY BE NEEDED FOR THE COAST NORTH OF CAPE
MENDOCINO. CLOUD COVER MAY LIMIT COOLING IN SOME AREAS SO HELD OFF
ON ISSUING A FROST ADVISORY AT THIS POINT. INLAND AREAS THAT
MANAGE TO CLEAR OUT WILL LIKELY SEE FOG IN THE VALLEYS AS WELL.

FRIDAY THE UPPER LEVEL TROUGH BEGINS TO PULL OUT OF THE AREA. ONE
FINAL VORT MAX LOOKS TO MOVE DOWN FROM THE NORTH FRIDAY AFTERNOON.
WITH SOME DAYTIME HEATING THIS LOOKS TO SPARK OFF SOME SHOWERS
OVER THE HIGHER TERRAIN. AGAIN SOUNDS PROFILES DIDNT LOOK
FAVORABLE ENOUGH FOR THUNDER BUT IT IS HARD TO RULE OUT AN
ISOLATED STRIKE COMPLETELY. THE BEST CHANCE LOOKS TO BE OVER
TRINITY COUNTY AND INTERIOR MENDOCINO COUNTY.

FRIDAY NIGHT INTO SATURDAY MORNING WILL LIKELY SEE WIDESPREAD
VALLEY FOG ACROSS THE INTERIOR. NORTHERLY WINDS SHOULD KEEP THE
LEE SIDES OF THE CAPES...SUCH AS CRESCENT CITY AND SHELTER COVE...
MAINLY CLEAR...BUT ELSEWHERE ALONG THE COAST MODELS ARE SUGGESTING
SOME MORNING CLOUDS. ONCE THESE CLEAR SATURDAY SHOULD BE A MOSTLY
CLEAR DAY.

SUNDAY OFFSHORE FLOW LOOKS TO INCREASE AS THE RIDGE CONTINUES TO
BUILD. THIS SHOULD KEEP THE COAST MAINLY CLEAR OF LOW CLOUDS AND
FOG...ALTHOUGH INLAND AREAS WILL LIKELY SEE FOG AND LOW CLOUDS IN
THE VALLEYS AGAIN. THE MAIN FORECAST CHALLENGE THEN BECOMES A WARM
FRONTAL BOUNDARY IN THE AREA. MODELS CONTINUE TO STRUGGLE WITH THE
LOCATION AND TIMING OF THIS FEATURE. AT THIS POINT ALL MODELS HAVE
KEPT THE RAIN ON SUNDAY TO THE NORTH OF THE AREA...BUT CLOUD COVER
MAY BE AN ISSUE. MODELS SEEM TO TYPICALLY UNDER DO THE MOISTURE IN
THESE WARM FRONTS SO THERE MAY BE MORE CLOUD COVER THAN CURRENTLY
IN THE FORECAST. MKK

.LONG TERM...THE RIDGE REMAINS IN PLACE ON MONDAY...HOWEVER THE
GFS SHOWS A STATIONARY FRONT JUST NORTH OF THE OREGON BORDER
BRINGING CLOUDS AND SOME LIGHT RAIN TO DEL NORTE COUNTY. THE
ECMWF KEEPS THE RIDGE SLIGHTLY STRONGER AND THE CLOUDS AND RAIN
OUT THE AREA. THIS BOUNDARY REMAINS IN THIS AREA THROUGH MIDWEEK.
GENERALLY A RIDGE REMAINS OVER THE AREA...HOWEVER WEAK WAVES TRY
TO RIDE OVER THE TOP OF THE RIDGE PUSHING THE BOUNDARY SLIGHTLY
SOUTH AND BRINGING CLOUDS TO THE AREA AND LIGHT RAIN TO DEL NORTE
COUNTY. BUMPED UP POPS SLIGHTLY...BUT CONFIDENCE IS LOW AS MODELS
CONTINUE TO STRUGGLE WITH THE STRENGTH AND TIMING OF THESE WAVES
MOVING OVER THE RIDGE. MKK

&&

.AVIATION...AN UPPER LEVEL TROUGH CONTINUES TO SIT OVER NORTHWEST
CALIFORNIA. NEAR THE COAST...LIGHT OFFSHORE MID LEVEL FLOW ON THE
NORTHEAST SIDE OF A DEVELOPING SURFACE LOW OFF THE MENDOCINO COAST
IS ALLOWING MOSTLY VFR CONDITIONS TO PERSIST EVEN WITH LIGHT SURFACE
WINDS. FARTHER INLAND VALLEY FOG HAS DEVELOPED WITH WIDESPREAD IFR
CONDITIONS. BY MID TO LATE MORNING MIXING SHOULD INCREASE RAISING
CEILINGS INFO VFR ACROSS ALL OF NORTHWEST CALIFORNIA. GOOD
RADIATIONAL COOLING TONIGHT AS THE SURFACE LOW MOVES SOUTHEAST OF
THE AREA SHOULD ALLOW LOW CIGS TO DEVELOP ONCE AGAIN ACROSS INTERIOR
VALLEYS AND POSSIBLY EVEN AT CEC AND ACV AS OFFSHORE FLOW WEAKENS.
RPA

&&

.MARINE...A SHORTWAVE WILL BEGIN TO ROUND THE BASE OF A DEEP UPPER
LEVEL TROUGH OVER NORTHERN CALIFORNIA THIS MORNING JUST SOUTH OF THE
NW CALIFORNIA COASTAL WATERS. SATELLITE AND RADAR INDICATES AN AREA
OF SURFACE LOW PRESSURE IS DEVELOPING 60-100 NM OFF THE SOUTHERN
MENDOCINO COAST. NORTH AND EAST OF THIS LOW SCATTERED SHOWER
ACTIVITY HAS BEEN DEVELOPING ALL NIGHT WITH SOME ROBUST SHOWERS
LIKELY PRODUCING SMALL HAIL. THE LOW WILL MOVE SOUTH THROUGH THE DAY
TODAY SLOWLY SHIFTING THE BEST FORCING SOUTH AND DECREASING THE
SHOWER COVERAGE OVER THE WATERS. THUS THE BEST CHANCE OF ANY MORE
STRONG SHOWERS/STORMS WILL BE THIS MORNING ACROSS THE SOUTHERN
MARINE ZONES OFF THE MENDOCINO COAST. WINDS WILL REMAIN GENERALLY
LIGHT ACROSS THE WATERS TODAY AS THIS LOW SLIDES SOUTH AND SEAS WILL
SUBSIDE. THUS SMALL CRAFT ADVISORIES HAVE BEEN ALLOWED TO EXPIRE.

LATER TONIGHT THE UPPER TROUGH WILL BEGIN TO MOVE FARTHER INLAND AND
HIGH PRESSURE WILL BUILD OVER THE EASTERN PACIFIC. THIS WILL ALLOW
THE PRESSURE GRADIENT TO TIGHTEN AND NORTHERLY WINDS TO INCREASE. BY
LATE TONIGHT INTO FRIDAY MORNING SCA CRITERIA WINDS WILL LIKELY
DEVELOP ACROSS THE SOUTHERN AND OUTER WATERS. WITH THIS OCCURRING IN
THE THIRD PERIOD HAVE OPTED TO HOLD OFF ON ISSUING THE ADVISORIES AT
THIS TIME. NORTHERLY WINDS WILL BE MAINTAINED THROUGH THE WEEKEND AS
HIGH PRESSURE HOLDS OF THE COAST AND AN UPPER LEVEL RIDGE DOMINATES
ALOFT. A LONGWAVE TROUGH WILL MOVE TOWARD THE COAST EARLY NEXT WEEK
WITH A WARM FRONT MOVING NORTH INTO THE PACIFIC NORTHWEST. LIGHT TO
MODERATE SOUTHWESTERLY FLOW WILL DEVELOP AHEAD OF THIS TROUGH EARLY
TO MID NEXT WEEK ACROSS THE NORTHERN WATERS. RPA

NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
