AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
ISSUED BY NATIONAL WEATHER SERVICE MEDFORD OR
144 PM PDT TUE SEP 2 2014

.SYNOPSIS...DRY CONDITIONS WILL CONTINUE THROUGH AT LEAST THE END
OF THE WEEK, POSSIBLY INTO NEXT WEEKEND. OFFSHORE FLOW WILL
PERSIST INTO THE MIDDLE OF THE WEEK. THE THERMAL TROUGH WILL BUILD
NORTH AND WEAK ONSHORE FLOW WILL RETURN. THE OFFSHORE FLOW WILL
CARRY AREAS OF SMOKE FROM THE HAPPY CAMP COMPLEX TOWARDS THE
COAST. TEMPERATURES WILL REMAIN WARM FOR INLAND LOCATIONS THIS
WEEK. -PETRUCELLI


&&

.DISCUSSION...CURRENT VISIBLE IMAGE SHOWS MARINE STRATUS STARTING
TO CREEP BACK TOWARDS CRESCENT CITY. OBSERVATIONS THE PAST FEW
HOURS HAS BEEN SHOWING THE STRATUS GOING THERE, THEN RETREATING.
EXPECT THIS TREND TO CONTINUE INTO EARLY THIS EVENING, THEN
OFFSHORE FLOW SHOULD KEEP THINGS CLEAR FOR TONIGHT. THE MARINE
STRATUS JUST SOUTH OF CRESCENT CITY TOWARDS CAPETOWN IS SHOWING
SIGNS OF ERODING AND IT`S POSSIBLE IT COULD CLEAR OUT TOWARDS
EVENING. MODELS ARE IN FAIRLY GOOD AGREEMENT WITH THE OVERALL
PICTURE FOR THE WEEK AHEAD. CONDITIONS WILL REMAIN DRY THROUGH THE
FORECAST PERIOD WITH WARM TEMPERATURES FOR INLAND LOCATIONS.
OFFSHORE FLOW IS EXPECTED TO INCREASE TONIGHT BRINGING GUSTY
BREEZES OVER THE HIGHER TERRAIN IN DEL NORTE HUMBOLDT AND TRINITY
COUNTIES ALONG WITH MODERATE TO POOR HUMIDITY RECOVERIES. THE
THERMAL TROUGH IS EXPECTED TO EXPAND NORTHWARD DURING THE DAY
THURSDAY. THIS WILL WEAKEN THE OFFSHORE FLOW AND WE`LL SEE THE
MARINE STRATUS START TO SURGE NORTHWARD TOWARDS POINT ARENA AND
FORT BRAGG LATE THURSDAY AFTERNOON OR EVENING. THE MARINE STRATUS
WILL CONTINUE TO PUSH NORTHWARD THROUGH CAPETOWN THURSDAY NIGHT
AND WILL GET CLOSE TO EUREKA. FOR NOW IT LOOKS LIKE IT WILL
REMAIN OFFSHORE, BUT IT WILL BE CLOSE.

THE THERMAL TROUGH WILL CONTINUE TO BUILD NORTH UP THROUGH THE PAC
NW FRIDAY UNTO NEXT WEEKEND. WE`LL REMAIN DRY OVER THE FORECAST
AREA WITH MARINE STRATUS ALONG THE COAST AND ADJACENT RIVER VALLEY
LOCATIONS WITH TEMPERATURES NEAR OR SLIGHTLY BELOW NORMAL. INLAND
SKIES REMAIN CLEAR WITH ABOVE NORMAL TEMPERATURES. -PETRUCELLI


&&

.AVIATION...LOW STRATUS CONTINUES TO HUG THE COASTLINE SOUTH OF
CRESCENT CITY EARLY THIS AFTERNOON. KACV SHOULD SEE CIGS BURN OFF
WITHIN THE NEXT FEW HOURS...YET LOW CLOUDS WILL REMAIN ALONG THE
COAST. VFR CONDITIONS ARE EXPECTED INLAND AND ACROSS THE KCEC
TERMINAL FOR THE REMAINDER OF THE AFTERNOON. STRATUS WILL LIKELY
RETURN AFTER 06Z WEDNESDAY ACROSS COASTAL LOCATIONS AND PERSIST
THROUGH THE MORNING HOURS WITH VFR CONDITIONS AND LIGHT WINDS AT
KUKI THROUGH THE FORECAST PERIOD.


&&

.MARINE...THE GRADIENT BETWEEN HIGH PRESSURE OFFSHORE THE PAC NW
COAST AND A THERMAL TROF OVER THE CA MAINLAND WILL TIGHTEN OVER THE
NEXT 24 HOURS. THIS IS INCREASING N WINDS TO SOLID GALE FORCE OVER
THE WATERS BEYOND 10 NM. THE GALES OVER THE OUTER WATERS WILL BRING
STEEP SEAS TO THE WATERS NEARER TO SHORE NORTH OF CAPE MENDOCINO.
THE HAZARDOUS SEAS WATCH HAS BEEN UPGRADED TO A WARNING FOR THOSE
WATERS. THE PRESSURE GRADIENT WILL RELAX FAIRLY RAPIDLY WED NIGHT AS
THE THERMAL TROF SHIFTS TOWARD THE COAST. JBL


&&

.FIRE WEATHER...THE SHORT WAVE DIGGING INTO THE PACNW THROUGH
TONIGHT WILL PRODUCE DRIER AIR AND AN INCREASING OFFSHORE PRESSURE
GRADIENT OVER THE DISTRICT TONIGHT INTO WEDNESDAY. THE RESULT WILL
BE POOR OVERNIGHT RECOVERIES AND CONTINUED VERY DRY AFTERNOON
MINIMUM HUMIDITY WEDNESDAY. HAVE GONE WITH A RED FLAG WARNING FOR
THIS OCCURRENCE WHICH WILL MATCH UP WELL WITH THE HEADLINE FROM THE
MEDFORD WFO. COORDINATION WITH AREA IMETS RESULTED IN NOT ISSUING A
WATCH FOR THE CONTINUED CONDITION EXPECTED THROUGH THURSDAY MORNING.
BUT WE DO EXPECT THE DRY AND BREEZY CONDITION TO LIKELY CONTINUE
ACROSS THE RIDGES IN AT LEAST ZONES 203 AND 204. SO STAY TUNED.
THE THERMAL TROUGH WILL SPREAD NORTH AND THE GRADIENT SLACKENS
FRIDAY SO THE WINDS WILL WEAKEN. LOW PRESSURE THAT DEVELOPS OFF
NORTHERN CALIFORNIA FRIDAY AND MOVES SLOWLY ACROSS THE AREA OVER
THE WEEKEND LOOKS LIKE IT`LL LEAVE THE AREA FREE FROM
LIGHTNING...WHICH WAS A CONCERN AT ONE POINT FOR SOME. LOOKS
FAIRLY DRY AND NONE OF THE MODELS ARE INDICATING ANY PRECIP SO
CONFIDENCE IS GOOD. STAVISH


&&

.UPDATE...ADJUSTED SKY COVER AND PATCHY AREAS OF FOR TODAY. THE
REST OF THE FORECAST IS STILL ON TRACK. -PETRUCELLI


&&

.SYNOPSIS...DRY CONDITIONS WILL CONTINUE FOR THE REST OF THE WEEK.
OFFSHORE FLOW FLOW WILL CONTINUE TONIGHT INTO EARLY WEDNESDAY
MORNING AND AREAS OF SMOKE WILL PERSIST FROM THE HAPPY CAMP
COMPLEX TOWARDS THE COAST. TEMPERATURES WILL REMAIN WARM FOR
INLAND LOCATIONS THIS WEEK. -PETRUCELLI


&&

.DISCUSSION...A THERMAL TROUGH IS NOW ALONG THE COAST AND THIS IS
EXPECTED TO STRENGTHEN THIS AFTERNOON THROUGH WEDNESDAY. THE MAIN
IMPACT FROM THIS WILL BE MODERATE WINDS OVER THE RIDGES OVER THE
NORTHERN PART OF HUMBOLDT AND DEL NORTE COUNTIES. A DRY FRONT WILL
PUSH SOUTH TOWARDS THE AREA TONIGHT, BUT THE MAIN EFFECT WILL BE A
DRIER AIR MASS AND INCREASING OFFSHORE FLOW RESULTING IN MODERATE
TO POOR RIDGETOP RECOVERIES. THE THERMAL TROUGH IS EXPECTED TO
EXPAND NORTHWARD TOWARDS THE END OF THE WEEK WHICH WILL WEAKEN THE
OFFSHORE FLOW. -PETRUCELLI




&&

.AVIATION...MARINE STRATUS CONTINUES TO HUG ALONG THE COAST, BUT
SKIES ARE CLEAR JUST NORTH OF THE HUMBOLDT/DEL NORTE COUNTY LINE.

REDUCE VISIBILITIES AT TIMES. CURRENT VISIBLE IMAGE IS SHOWING
SIGNS OF THE MARINE STRATUS ALONG THE HUMBOLDT/MENDOCINO COUNTY
LINE IS STARTING TO RETREAT BACK TOWARDS THE COAST, BUT IS
EXPECTED TO STICK AROUND INTO AT EAST EARLY AFTERNOON. CURRENT TAF
AT KACV SHOWS STRATUS BREAKING OUT AROUND 18Z, BUT THIS COULD BE
DELAYED BY AN HOUR OR TWO. -PETRUCELLI


&&

.MARINE...THE GRADIENT BETWEEN HIGH PRESSURE OFFSHORE THE PAC NW
COAST AND A THERMAL TROF OVER THE CA MAINLAND WILL TIGHTEN OVER THE
NEXT 36 HOURS. THIS WILL ALLOW N WINDS TO INCREASE TO SOLID GALE
FORCE OVER THE OFFSHORE WATERS TODAY. HAVE KEPT CURRENT HEADLINES AS
THEY ARE. THE PERIOD OF POSSIBLE HAZARDOUS SEAS OVER THE N NEAR
SHORE WATERS LOOKS TO BE SHORT LIVED...SO LEFT THE HAZARDOUS SEAS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
331 PM PDT MON SEP 1 2014

.SYNOPSIS...WARM TEMPERATURES TODAY AND MODERATE TEMPERATURE
OVERNIGHT WILL GIVE WAY TO A COOLING TREND FOR NW CALIFORNIA AS A
DISTURBANCE APPROACHES FROM THE NW. DRY CONDITIONS ARE EXPECTED TO
REMAIN THROUGH THE WEEK. OVERNIGHT AND EARLY MORNING OFFSHORE FLOW
WILL CONTINUE TO MOVE SMOKE FROM THE HAPPY CAMP COMPLEX TOWARD THE
COAST.

&&

.DISCUSSION...AFTERNOON SATELLITE SHOWS A WEAK RIDGE NOSING TOWARD
NWCA FROM THE SSW WHILE A MORE ZONAL PATTERN EXISTS ACROSS THE PAC
NW. THIS RIDGE IS ALLOWING FOR TEMPS TO WARM QUICKLY THIS AFTERNOON
ACROSS THE REGION. WITH A WARM AIR MASS IN PLACE AND THE RIDGE
SLOWLY SHIFTING TO THE ESE OVER THE NEXT 12 TO 24 HOURS, OVERNIGHT
TEMPS SHOULD REMAIN FAIRLY MODERATE. MODELS ARE SHOWING THE ZONAL
PATTERN BUCKLING OVER THE NEXT DAY AND DIGGING AN UPPER TROUGH INTO
CALIFORNIA. THIS SHOULD TURN THE FLOW ALOFT TO A MORE WESTERLY
ORIENTATION, BUT THE UPPER RIDGE TO THE SOUTH WILL CONTINUE TO
INDUCE A SURFACE THERMAL TROUGH WHICH WILL CAUSE THE WINDS TO BE
MORE N TO NE IN THE OVERNIGHT AND EARLY MORNING HOURS. SMOKE FROM
THE HAPPY CAMP COMPLEX WILL CONTINUE TO BE A CONCERN AS THIS WIND
DIRECTION WILL LIKELY DRIVE SMOKE TOWARD OF NWCA THE COAST THE NEXT
FEW DAYS. THE UPPER TROUGH WILL BRING A COOLING TREND TO NWCA AS IT
PULLS IN COOL AIR FROM THE GULF OF ALASKA AND THE TROUGH ITSELF
PROVIDE A MIXING MECHANISM TO BRING SOME OF THAT COOL AIR TOWARD THE
SURFACE. OVERALL, THE NEXT FEW DAYS SHOULD REMAIN FAIRLY NICE, BUT
COOLER THAN TODAY.

FOR LATE WEEK WE ARE STILL WATCHING FOR THE POSSIBILITY OF A SHOWER
OR THUNDERSTORM. MODELS CONTINUE TO HAVE ISSUES GRAVITATING TOWARD A
SOLUTION WITH ONE RUN MAINTAINING A CUTOFF LOW SOMEWHERE ALONG THE N
CAL COAST AND THE NEXT RUN ABSORBING THE UPPER LOW INTO THE BROADER
PATTERN. THE TWO PIECES TO WATCH WILL BE IF THE CUTOFF LOW REMAINS
INTACT AND HOW MUCH SUB TROPICAL MOISTURE GETS ENTRAINED INTO THE
LOW. IF THESE OCCUR, THEN WE`LL BE LOOKING AT PLACEMENT OF THE LOW
FOR CONVECTIVE POSSIBILITIES. DID NOT MAKE ANY SIGNIFICANT CHANGES
TO THE LONG TERM FORECAST AS THE UNCERTAINTY IS TOO HIGH TO HAVE ANY
VALUE IN CHANGES. BFG

&&

.AVIATION...OFFSHORE WIND FLOW WILL RELAX TONIGHT AND EARLY TUE
AS A TROUGH ALOFT MOVES OVER THE PAC NW. SLIGHTLY MORE STRATUS AND
FOG MAY DEVELOP BY EARLY TUE MORNING ALONG THE NORTH COAST. THE
STRATUS AND FOG SHOULD MIX OUT AGAIN BY AFTERNOON. NE-E FLOW FROM
THE HAPPY CAMP COMPLEX WILL PROBABLY TRANSPORT PATCHY SMOKE WESTWARD
AND SOUTHWARD AGAIN TONIGHT AND TUE MORNING. SOME VSBY OBSCURATIOON
WILL BE POSSIBLE TUE MORNING FROM THE SMOKE. OTHERWISE CLEAR SKIES
WILL CONTINUE TO PREVAIL ACROSS MOST OF THE AREA THROUGH
TUESDAY.

&&

.MARINE...HIGH PRESSURE OVER THE NE PAC WILL CONTINUE TO BUILD
EASTWARD THROUGH MID WEEK. THIS BUILDING RIDGE COUPLED WITH A
THERMALLY INDUCED TROUGH ALONG THE NORTHERN CALIFORNIA COAST WILL
MAINTAIN MODERATELY STRONG NORTH WINDS...MAINLY IN THE OUTER
WATERS...THROUGH WED NIGHT. WINDS SHOULD REACH GALE FORCE AS HIGH
PRESSURE ALOFT STRENGTHENS AND A LOW PRESSURE SYSTEM MOVES INTO THE
NORTHERN ROCKIES ON TUE. NORTHERLY GUSTS OF 40-45 KT ARE EXPECTED IN
PZZ470 ON WED AS THERMALLY INDUCE LOW PRESSURE INTENSIFIES. A
WARNING HAS BEEN HOISTED FOR THE OUTER WATERS STARTING ON TUE AND
CONTINUING THROUGH WED NIGHT. A WATCH FOR HAZARDOUS SEAS HAS BEEN
HOISTED FOR THE INNER WATERS NORTH OF CAPE MENDO...WITH STEEP SEAS
AROUND 13 FT EXPECTED WED NIGHT. NORTHERLY WINDS AND SEAS LOOK TO

449 AM PDT MON SEP 1 2014

.SYNOPSIS...AN UPPER HIGH PRESSURE RIDGE SOUTH OF THE AREA WILL
BRING A WARM AND MOSTLY SUNNY LABOR DAY TO NW CALIFORNIA. EARLY
MORNING LOW CLOUDS OVER HUMBOLDT BAY AND THE EEL RIVER VALLEY WILL
GIVE WAY TO SUNSHINE. MORE SEASONABLE WEATHER IS EXPECTED BY MID
TO LATE WEEK WITH CONTINUED DRY CONDITIONS.

&&

.DISCUSSION...LOW CLOUDS HAVE RE-FORMED ALONG PORTIONS OF THE REDWOOD
COAST EARLY THIS MORNING...MAINLY AROUND HUMBOLDT BAY AND UP THE
EEL RIVER VALLEY. THIS CLOUDINESS IS LESS EXTENSIVE THAN ON
SUNDAY...AND IS EXPECTED TO ERODE FAIRLY QUICKLY THIS MORNING.

TEMPERATURES WILL MAX OUT OVER THE INTERIOR THIS AFTERNOON...WITH
A FEW READINGS NEAR THE CENTURY MARK. COASTAL TEMPERATURES SHOULD
BE CLOSE TO SUNDAY`S READINGS...WITH SOME PORTIONS OF THE REDWOOD
COAST REACHING THE LOWER TO MID 70S BEFORE SURFACE WIND FLOW BACKS
A BIT MORE ONSHORE. TEMPERATURES WILL GRADUALLY COOL OVER THE
NEXT FEW DAYS AS THE PENCIL UPPER RIDGE S OF THE AREA PINCHES OFF
AND A LOW PRESSURE TROF DIGS OVER THE PAC NW. THIS TROF IS
EXPECTED TO BE MOSTLY DRY.

A CLOSED UPPER LOW MAY DEVELOP IN THE BASE OF THE UPPER TROF OFF
THE N CA COAST BY LATE IN THE WEEK. SOME MONSOONAL MOISTURE MAY GET
PULLED W TOWARD THE AREA BY THE WEEKEND IF THAT SCENARIO PANS OUT.
HAVE CONTINUED VERY MINIMAL POPS OVER THE INTERIOR DURING THIS
TIME FRAME. HOWEVER...THE FORECAST WORDING REMAINS DRY. /SEC

&&

.AVIATION...IFR TO LIFR CONDITIONS AND LIGHT WINDS TO CALM
CONDITIONS WILL CONTINUE AT KCEC THROUGH THE EARLY MORNING DUE
TO LOWER CEILINGS AND VISIBILITIES. MFR TO IFR CONDITIONS AND
LIGHT WINDS TO CALM CONDITIONS WILL CONTINUE AT KACV THROUGH THIS
MORNING DUE TO REDUCED CEILINGS. MVFR TO VFR CONDITIONS WILL PREVAIL AT
KCEC AND KACV THIS AFTERNOON WITH LIGHT TO MODERATE WINDS. VFR
CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL CONTINUE AT KUKI
THROUGH TUESDAY.

&&

.MARINE...NORTHERLY WINDS AND THE SEAS WILL CONTINUE TO GRADUALLY
INCREASE THE NEXT FEW DAYS AS THE OFFSHORE HIGH PRESSURE RIDGE
STRENGTHENS AND THE INLAND THERMAL LOW PRESSURE TROUGH INTENSIFIES
GRADUALLY TIGHTENING THE PRESSURE GRADIENT ACROSS THE WATERS. WINDS
AND SEAS WILL BE HIGHER ACROSS THE OUTER WATERS. A SMALL CRAFT ADVISORY
IS IN EFFECT ACROSS THE OUTER WATERS DUE TO THE INCREASE IN THE WINDS
AND SEAS. A GALE WATCH IS IN EFFECT ACROSS THE NORTHERN OUTER WATERS
TONIGHT THROUGH WEDNESDAY MORNING AND WILL LIKELY BE UPGRADED TO A GALE
WARNING DUE TO INCREASING WIND GUSTS TO GALE FORCE TONIGHT AND TUESDAY.
A SMALL CRAFT ADVISORY WILL BE IN EFFECT ACROSS THE NORTHERN NEAR SHORE
WATERS FROM EARLY TUESDAY MORNING THROUGH EARLY THURSDAY MORNING DUE TO
THE INCREASING SEAS. A SMALL CRAFT ADVISORY WILL BE IN EFFECT ACROSS THE
SOUTHERN NEAR SHORE WATERS FROM TUESDAY AFTERNOON THROUGH WEDNESDAY
AFTERNOON DUE TO INCREASING SEAS. WINDS AND SEAS WILL BE HIGHER NEAR
CAPES AND POINTS.

&&

.FIRE WEATHER...VERY DRY CONDITIONS ARE EXPECTED TO CONTINUE
THROUGH MONDAY NIGHT OVER THE INTERIOR WITH THE DRIEST CONDITIONS
OVER RIDGETOPS. SOME OF THE N TO NE FLOW WILL BECOME GUSTY ALONG
THE RIDGETOPS TODAY...PARTICULARLY NEAR CAPE MENDOCINO.
DESCRIPTIVE HEADLINES TO THIS EFFECT HAVE BEEN CONTINUED IN THE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
345 PM PDT SUN AUG 31 2014

.SYNOPSIS...HIGH PRESSURE BUILDING OVER THE AREA WILL ALLOW FOR A
CLEAR NIGHT ACROSS MUCH OF NW CALIFORNIA. PATCHES OF FOG AND LOW
CLOUDS ARE POSSIBLE ALONG THE COAST AS THE MARINE LAYER
COMPRESSES. LABOR DAY WILL BRING CONTINUED WARMING TO THE INTERIOR REGIONS
WHILE THE COAST REMAINS SEASONABLE.

&&

.DISCUSSION...MODELS REMAIN IN GOOD AGREEMENT WITH A WEAK UPPER
RIDGE NOSING INTO THE REGION. AFTERNOON WV SATELLITE IS SHOWING A
SHORTWAVE MOVING INTO THE PAC NW WHICH IS KEEPING THE CLOUDS MIXED
OUT TODAY. AS THE RIDGE TAKES HOLD, THE MARINE LAYER WILL BE
COMPRESSED TO THE LOWEST LEVELS ALONG THE COAST. HOWEVER, WEAK
OFFSHORE FLOW IS EXPECTED OVERNIGHT WHICH SHOULD KEEP THE AIR MASS
DRY AND INHIBIT THE WIDESPREAD FOG AND LOW CLOUDS ALONG THE COAST.
WITH NW FLOW OVER THE WATERS AND THE HUMBOLDT BAY REGION FACING
WNW, HAVE OPTED TO KEEP SOME CLOUDS AND FOG IN THE AREA DUE TO THE
EASE OF MARINE MOISTURE TO WORK ITS WAY INTO THE AREA. OTHERWISE,
MOST AREAS SHOULD REMAIN FAIR.

OVERNIGHT LOW ACROSS THE INTERIOR SHOULD REMAIN MILD UNDER OFFSHORE
FLOW, ESPECIALLY AROUND THE DEL NORTE REGION. THIS WILL HELP LABOR
DAY TO START ON THE WARM SIDE WHICH WILL EASILY PUT US AHEAD FOR MAX
TEMPS. LOOK FOR A WARM UP OF 2 TO 7 DEGREES ACROSS THE INTERIOR.
LABOR DAY AT THE COAST IS EXPECTED TO BE NICE WITH MILD TEMPS,
PLENTY OF SUNSHINE, AND AFTERNOON ONSHORE WINDS.

THE RIDGE WILL BEGIN TO SHIFT EASTWARD ON TUESDAY ALLOWING FOR A
SLIGHT COOLING. MODELS CONTINUE TO INDICATE AN UPPER TROUGH DRIVING
IN FROM THE NW DURING THE SECOND HALF OF THE WEEK. WHILE A COOL DOWN
IS A SURE BET, SHOWERS AND THUNDERSTORMS ARE NOT. MODELS CONTINUE TO
SHOW THE TROUGH PICKING UP THE REMNANTS OF TROPICAL SYSTEM MARIE,
BUT HOW MUCH MOISTURE REMAINS WITH IT AND WHERE EXACTLY IT WILL MAKE
ITS WAY ASHORE REMAINS VERY UNCERTAIN. SO HAVE LEFT THE MED TO LONG
RANGE FORECAST UNTOUCHED. BFG

&&

.AVIATION...MOSTLY CLEAR SKIES WILL CONTINUE TO PREVAIL THROUGH
MONDAY. OFFSHORE FLOW WILL SUPPRESS STRATUS DEVELOPMENT TONIGHT. A
FEW PATCHES OF STRATUS AND FOG MAY FORM AROUND HUMBOLDT BAY AND IN
THE EEL DELTA/VALLEY EARLY MONDAY MORNING. THESE PATCHES SHOULD
CLEAR OUT FAIRLY QUICKLY WITH DAYTIME HEATING. HOWEVER THE NE-E
WIND FLOW WILL PROBABLY TRANSPORT PATCHY SMOKE WESTWARD AND
SOUTHWARD BY EARLY MONDAY MORNING. THE SMOKE WILL CREATE VSBY
RESTRICTIONS.

&&

.MARINE...HIGH PRESSURE CENTERED 1400 MILES WEST OF EUREKA WILL
CONTINUE TO SLOWLY BUILD EASTWARD THROUGH EARLY NEXT WEEK. THIS
RIDGE COUPLED WITH THERMALLY INDUCED LOW PRESSURE OVER THE
CALIFORNIA INTERIOR WILL MAINTAIN MODERATELY STRONG NORTH WINDS
THROUGH MID WEEK. WINDS MAY REACH GALE FORCE ON TUE AND WED AS
HIGH PRESSURE ALOFT STRENGTHENS AND A LOW PRESSURE SYSTEM MOVES
INTO THE NORTHERN ROCKIES. NORTHERLY GUSTS OF 35-40 KT WILL BE
POSSIBLE IN PZZ470 ON TUE AND WED AS THERMALLY INDUCE LOW PRESSURE
INTENSIFIES ALONG THE NORTHERN CALIFORNIA COAST. IT IS STILL A
COUPLE DAYS OUT AND THE MODELS MAY BE TOO HIGH ON THE WINDS. FOR
NOW WILL HOLD OFF ON HOISTING A GALE WATCH UNTIL THE EVENT BECOMES
MORE CERTAIN.

&&

.FIRE WEATHER...VERY DRY CONDITIONS ARE EXPECTED TO CONTINUE
TONIGHT THROUGH MONDAY NIGHT AS HIGH PRESSURE SETTLES IN AND
OFFSHORE FLOW DEVELOPS. RECOVERIES ARE EXPECTED TO BE POOR
TONIGHT, INCLUDING ALONG RIDGES, DUE TO WARMER OVERNIGHT LOWS AND
DECREASED DEWPOINTS. SOME OF THE OFFSHORE FLOW MAY BECOME GUSTY
ALONG THE RIDGE IN THE MORNING HOURS. MONDAY WILL BE A HOT DRY
DAY. SEE THE GENERAL DISCUSSION FOR INFORMATION ON THE SYNOPTIC
CONDITIONS. TUESDAY WILL BE A TRANSITION DAY FOLLOWED BY A COOLING
AND MOISTENING TREND FOR THE SECOND HALF OF THE WEEK. BFG

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...SMALL CRAFT ADVISORY FROM 3 AM MONDAY TO 10 PM PDT THURSDAY
