AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PORTLAND OR
204 PM PDT TUE AUG 14 2012

ADDED FIRE WEATHER PORTION

.SYNOPSIS...OFFSHORE FLOW AND A STRONG UPPER LEVEL RIDGE WILL COMBINE
TO BRING A WARMING TREND WITH HOT WEATHER IN THE FORECAST AREA
THURSDAY AND FRIDAY. INCREASING HUMIDITY MAY LEAD TO A FEW
THUNDERSTORMS BY THE WEEKEND...WITH THE BEST CHANCE BEING IN THE
CASCADES.

&&

.SHORT TERM...LOW CLOUDS HAVE CLEARED BACK TO THE BEACHES...EXCEPT
FOR THE SOUTH WASHINGTON/NORTH OREGON COAST NEAR THE MOUTH OF THE
COLUMBIA RIVER. INCREASING ONSHORE FLOW WILL KEEP HIGH TEMPERATURES A
FEW DEGREES COOLER THIS AFTERNOON THAN YESTERDAY.

A THERMALLY INDUCED TROUGH OF LOW PRESSURE WILL BUILD NORTH ALONG THE
COAST WED...AS AN UPPER LEVEL RIDGE BUILDS FROM NEVADA NORTHWESTWARD
ACROSS OREGON. THE RESULTING OFFSHORE FLOW WILL BRING A WARMING TREND
TO THE AREA BEGINNING WEDNESDAY.

WITH FLOW TURNING OFFSHORE AND 850 MB TEMPS WARMING TO +18 TO +22 DEG
C WEDNESDAY...TEMPERATURES SHOULD EASILY REACH THE 90S FOR THE
INTERIOR VALLEYS...WITH A CHANCE OF 90 DEGREE TEMPERATURES ALONG THE
COAST NORTH OF LINCOLN CITY THU.

THURSDAY AND FRIDAY WILL BE EVEN HOTTER AS THE AIR MASS ALOFT WARMS
UP. 00Z ECMWF SHOWS 850 MB TEMPS AROUND +23 TO +24 DEG C DURING THE
AFTERNOONS. WITH OFFSHORE FLOW...THIS SHOULD BE ENOUGH FOR THE INLAND
VALLEYS TO REACH 100 DEGREES. WILL ISSUE A HEAT WATCH WITH THE
AFTERNOON PACKAGE. LIKENS

.LONG TERM...VERY WARM AND SUNNY CONDITIONS START OFF THE EXTENDED
PERIOD ON FRI AS A STRONG UPPER RIDGE PERSISTS OVER THE REGION.
STILL EXPECTING A 100 DEGREE DAY ON FRI...WITH A SLIGHT CHANCE OF
THUNDERSTORMS MAINLY OVER THE CASCADES FRI NIGHT AS UPPER LEVEL FLOW
TURNS MORE SOUTH/SOUTHEAST. MODELS ARE IN GOOD AGREEMENT SHOWING A
SURFACE TROUGH MOVING INLAND BY SAT...WHICH WILL ALLOW TEMPS TO COOL
A BIT. THE BEST THUNDERSTORM THREAT STILL LOOKS LIKE SAT AS THE FLOW
ALOFT VEERS MORE SOUTHERLY BRINGING PLENTY OF MID LEVEL MOISTURE
INTO THE FORECAST AREA. BEHIND THE TROUGH...EXPECT A COOLING TREND
TO BEGIN SUN AS THE AIRMASS COOLS AND ONSHORE FLOW BECOMES
REESTABLISHED. TEMPS RETURN BACK TO NORMAL EARLY NEXT WEEK WITH
COASTAL HIGHS IN THE UPPER 60S AND INLAND HIGHS NEAR 80. /27

&&

.AVIATION...MARINE STRATUS HAS PUSHED JUST OFFSHORE ALONG THE CENTRAL
OR COAST AND KONP HAS IMPROVED TO VFR. HOWEVER...PATCHES OF MVFR
REMAIN ALONG THE N OR AND S WA COASTS. EXPECT THESE CONDITIONS TO
PERSIST THROUGH THE REMAINDER OF THE AFTERNOON...WITH KAST REMAINING
PREDOMINANTLY MVFR. MUCH LIKE LAST NIGHT...EXPECT MARINE
STRATUS TO SURGE BACK INTO THE COAST THIS EVENING. MVFR/IFR
CONDITIONS SHOULD REDEVELOP DURING THE EVENING AND REMAIN OVERNIGHT
INTO TOMORROW MORNING. COASTAL CLOUDS WILL BE PUSHED OFFSHORE
QUICKLY TOMORROW MID MORNING AS AN OFFSHORE FLOW PATTERN
DEVELOPS. MEANWHILE...WIDESPREAD VFR CONDITIONS ARE EXPECTED TO
PERSIST INLAND THROUGH THE NEXT 24 HRS. ONE POTENTIAL EXCEPTION IS
AREAS ALONG THE LOWER COLUMBIA...WHERE A BRIEF PERIOD OF MVFR CIGS
MAY OCCUR AS STRATUS TRIES TO PUSH UP THE RIVER.

KPDX AND APPROACHES...EXPECT VFR CONDITIONS THROUGH THE NEXT 24
HRS. SOME MARINE STRATUS MAY PUSH UP THE COLUMBIA TOMORROW
MORNING...BUT DO NOT CURRENTLY EXPECT THAT IT WILL MAKE IT INTO THE
METRO AREA. JFP

&&

.MARINE...GUSTY NORTH/NORTHWESTERLY WINDS DEVELOPING THIS
AFTERNOON AS A THERMALLY INDUCED SURFACE LOW BUILDS OVER SOUTHWEST
OREGON AND HIGH PRESSURE REMAINS ANCHORED OVER THE NORTHEAST
PACIFIC. EXPECT GUSTY WINDS TO CONTINUE INTO THIS EVENING...WITH
THE STRONGEST WINDS OVER THE CENTRAL OR WATERS. WINDS WILL EASE A BIT
WEDNESDAY AS THE THERMAL TROUGH PUSHES NORTHWARD...AND NEAR SHORE
WINDS WILL TURN OFFSHORE. HOWEVER...LOW END SMALL CRAFT ADVISORY
WINDS REMAIN A POSSIBILITY FOR THE OUTER WATERS DURING THE LATE
AFTERNOON AND EVENING. THE TROUGH WILL PERSIST THROUGH THURSDAY. A
LOW WILL APPROACH THE WATERS FROM THE SW THURSDAY NIGHT AND LIGHT
SOUTHERLY WINDS WILL DEVELOP. THE LOW WILL BRUSH BY THE WATERS
FRIDAY AND SATURDAY.

SEAS SIT IN THE 3 TO 5 FT RANGE OVER THE NEXT FEW DAYS. BUT EXPECT
SOME CHOPPY LOW PERIOD WIND WAVES TO KICK UP DURING THE TIMES OF
GUSTIER WINDS IN THE AFTERNOONS AND EVENINGS TODAY AND TOMORROW.

.FIRE WEATHER...CONDITIONS ARE SHAPING UP FOR A COUPLE FIRE WEATHER
CONCERNS COVERING THE LATTER HALF OF THE WEEK. THE BUILDING THERMAL
TROUGH WILL ENHANCE NEAR SURFACE INSTABILITY MAINLY ACROSS THE
CENTRAL CASCADE FIRE ZONES WEDNESDAY AND THURSDAY THEN SPREADING
ACROSS THE REMAINING AREA THURSDAY NIGHT AND FRIDAY. THIS WOULD
MAINLY AGGRAVATE ONGOING WILDFIRES AND NOT NECESSARILY CREATE NEW
STARTS. A FIRE WEATHER WATCH HAS BEEN ISSUED FOR THIS WITH A DECENT
LIKELIHOOD OF BEING UPGRADED TO A RED FLAG WARNING OVER THE NEXT FEW
HOURS.

SECOND CONCERN WILL BE THE THUNDERSTORM POTENTIAL FOR LATER FRIDAY
AND SATURDAY. THE THERMAL TROUGH WILL ALSO CONTINUE THE DRYING AND
PREHEATING OF FUELS THUS MAKING THEM MORE RECEPTIVE FOR FIRE STARTS.
THE AMOUNT OF LIGHTNING AND THE AMOUNT OF RAINFALL REMAIN HIGHLY
UNCERTAIN AT THIS TIME BUT TYPICALLY CLARIFIES AS THE EVENTS DRAW
CLOSER. WILL CONTINUE MONITORING THIS SITUATION TO SEE IF ADDITIONAL
STATEMENTS BECOME NECESSARY. /JBONK
