AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
429 AM PDT WED JUL 17 2013

.SYNOPSIS...HIGH PRESSURE WILL ENSURE DRY CONDITIONS WILL PERSIST
THROUGH THE WEEKEND. LOW CLOUDS AND FOG CAN BE EXPECTED ALONG MUCH
OF THE COAST WITH ONLY LIMITED SUNSHINE THIS AFTERNOON FOR THE
BEACHES. A BUILDING RIDGE OF HIGH PRESSURE WILL RESULT IN HOT
INLAND TEMPERATURES THIS WEEKEND.

&&

.DISCUSSION...
ONLY FORECAST CHALLENGE IN THE NEXT COUPLE OF DAYS WILL BE COASTAL
CLOUDINESS. WE START OFF WITH A VERY DEEP MARINE LAYER FOR THIS TIME
OF YEAR, WITH CLOUDS PENETRATING WELL UP THE KLAMATH AND EEL RIVER
VALLEYS, AND EVEN INTO THE RUSSIAN RIVER VALLEY FROM THE WEST. WITH
TROUGHING LIFTING OUT, BUT RELATIVELY COOL TEMPERATURES ALOFT, THE
LOWER ATMOSPHERE WILL BE A BIT LESS STABLE THAN PREVIOUS DAYS, WHICH
SHOULD ALLOW FOR MORE MIXING AT THE COAST. HOWEVER, THE GRADIENT
IS WEAK AND ONSHORE, SO DO NOT EXPECT MUCH SUN UNTIL THE
AFTERNOON. WITH A NORTHERLY GRADIENT INCREASING OVER THE NEXT
COUPLE OF DAYS, EXPECT EARLIER CLEARING AT THE COAST EACH DAY. BY
FRIDAY, AREAS OF THE MENDOCINO COAST AND DEL NORTE COAST WILL SEE
SUNSHINE MOST OF THE DAY, WITH A DRYING, DOWNSLOPE COMPONENT
THERE.

ALSO BY FRIDAY, TEMPERATURES ACROSS THE INTERIOR WILL BEGIN TO
REALLY HEAT UP. MODELS ARE IN GOOD AGREEMENT OF A STRONG UPPER-LEVEL
RIDGE SHIFTING WESTWARD TOWARD THE WEST COAST THROUGH THE WEEKEND.
500MB HEIGHTS WILL RISE ABOVE 592DM AND 850 TEMPS WILL REACH 27-30C.
THIS WILL EASILY TRANSLATE TO SFC TEMPS IN THE INTERIOR VALLEYS OF
105-110F. TEMPERATURES MAY STAY ABOVE 100 DEGREES THERE MUCH OF NEXT
WEEK, BUT THERE WILL BE THE POSSIBILITY OF SOME CLOUD COVER AND EVEN
A FEW THUNDERSTORMS AS EARLY AS MONDAY AND TUESDAY. THE LAST FEW
RUNS OF THE GFS KEEP THE RIDGE CENTERED EAST OF NRN CA, WHICH WOULD
EVENTUALLY DRAW MID AND UPPER-LEVEL MONSOONAL MOISTURE NORTHWARD.
HOWEVER, OTHER MODEL GUIDANCE KEEPS THE RIDGE FLATTER AND FURTHER
SOUTH, WITH A MORE WESTERLY FLOW ALOFT AND SUBSEQUENTLY MUCH
DRIER AND MORE STABLE ATMOSHPERIC PROFILES. ADDED A SLGT CHC OF
T-STORMS MON AND TUE TO THE HIGH TERRAIN OF ERN TRINITY AND
MENDOCINO COUNTIES, BUT THERE IS STILL PLENTY OF UNCERTAINTY. AAD

&&

.AVIATION...THE UPPER LEVEL LOW HAS MOVED NORTHEAST OUT OF THE AREA
ALLOWING THE MARINE LAYER TO LIFT A BIT. COASTAL CIGS ARE RUNNING
ABOUT 1000 FT BUT MIXING AND A LITTLE SUBSIDENCE MAY PROMOTE SOME
BETTER CLEARING TODAY. THUS MVFR CONDITIONS COASTSIDE THROUGH THE
LATE MORNING HOURS ONCE AGAIN FOLLOWED BY LIFTING CIGS AND IMPROVING
VSBYS BY MIDDAY. INTERIOR AREAS MAY HAVE SOME MORNING LOW CLOUDS BUT
WILL GIVE WAY TO WIDESPREAD VFR BY LATE MORNING.

&&

.MARINE...NORTHERLY WINDS WILL RETURN AGAIN LATER THIS MORNING AS
HIGH PRESSURE REBUILDS OFF THE COAST. WINDS WILL SLOWLY INCREASE AND
WILL LIKELY REACH SMALL CRAFT LEVELS BY THURSDAY OVER THE OFFSHORE
WATERS.WINDS WILL CONTINUE TO SLOWLY INCREASE THROUGH FRIDAY AS
HIGH PRESSURE STRENGTHENS. GALE FORCE GUSTS ARE LIKELY BY FRIDAY
AFTERNOON OVER THE OUTER WATERS...AND PERSISTING THROUGH LATE
SATURDAY.

&&

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

GALE WATCH FROM FRIDAY AFTERNOON THROUGH SATURDAY EVENING
     PZZ470-475.
