316 PM PDT TUE JUN 30 2015

...UPDATED FOR FIRE WEATHER DISCUSSION...

SHORT TERM...TONIGHT THROUGH FRIDAY...THE WESTERN U.S. UPPER
LEVEL HIGH PRESSURE RIDGE WILL REBUILD NORTH INTO THE PACIFIC
NORTHWEST WEDNESDAY AND THURSDAY. THE RIDGE MAY FLATTEN SOME ON
FRIDAY DUE TO AN UPPER TROUGH MOVING INTO WESTERN CANADA. AS A
RESULT EXPECT DRY CONDITIONS WITH INCREASING SUBSIDENCE TO CAP ANY
STRAY MOUNTAIN CONVECTION. THIS INCREASING SUBSIDENCE WILL ALSO
LEAD TO INCREASING TEMPERATURES THROUGH THE PERIOD. HIGH TEMPS
WILL WARM FIRST FROM THE GORGE SOUTH TO CENTRAL OREGON, WITH SOME
COOLING EXPECTED IN THIS AREA FRIDAY DUE TO AN INITIAL WEAK MARINE
INTRUSION CAUSED BY THE CANADIAN TROUGH. HIGH TEMPS IN THIS AREA
WEDNESDAY AND THURSDAY AFTERNOONS WILL RUN AROUND 20 DEGREES ABOVE
SEASONAL. THUS HAVE ISSUED HEAT ADVISORIES FOR THE COLUMBIA RIVER
GORGE, NORTH-CENTRAL AND CENTRAL OREGON FOR WEDNESDAY AFTERNOON
THROUGH THURSDAY EVENING. ELSEWHERE HIGH TEMPS WEDNESDAY WILL BE
SIMILAR TO TODAY, THEN JUMP 3 TO 5 DEGREES THURSDAY. THE WARMEST
TEMPS THURSDAY AND FRIDAY WILL BE ACROSS MUCH OF THE COLUMBIA
BASIN, AND HEAT ADVISORIES HAVE EITHER BEEN EXTENDED OR ADDED IN
THIS AREA INTO FRIDAY EVENING. 90

LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...MODELS ARE NOT IN VERY
GOOD AGREEMENT IN THE LONG TERM WITH THE GFS DEVELOPING MORE OF A
TROUGH OVER THE PACIFIC NW WHILE THE ECMWF MAINTAINS A NARROW RIDGE.
EITHER WAY THERE DOES NOT APPEAR TO BE ANY MAJOR STORMS TO AFFECT
THE REGION DURING THE PERIOD. HOWEVER THERE MAY BE VERY ISOLATED
THUNDERSTORMS OVER THE EASTERN MOUNTAINS DURING THE AFTERNOON AND
EVENING SUNDAY THROUGH TUESDAY. ANY STORMS WOULD POSE A RISK FOR NEW
FIRE STARTS. TEMPERATURES LOOK TO BE SLIGHTLY COOLER WITH AFTERNOON
READINGS NUDGING DOWN SLIGHTLY BELOW THE CENTURY MARK EACH DAY IN
THE LOWER ELEVATIONS. THERE WILL BE PERIODS OF BREEZY WINDS IN THE
CASCADE GAPS DURING THE AFTERNOONS AND EVENINGS WHICH COULD POSE A
FIRE WEATHER HAZARD IN THE COLUMBIA RIVER GORGE OVER THE WEEKEND. 78

AVIATION...00Z TAFS...VFR CONDITIONS WITH CLEAR SKIES EXPECTED
THROUGH THE PERIOD. WINDS WILL DIMINISH THIS EVENING AND BECOME
TERRAIN DRIVEN OVERNIGHT. MOSTLY NORTH TO NORTHWEST WINDS ARE
EXPECTED WEDNESDAY AFTERNOON AT 5 TO 10 KT. 78

&&

.FIRE WEATHER...HIGH PRESSURE WILL CONTINUE TO DOMINATE THE INTERIOR
PACIFIC NORTHWEST FOR THE NEXT COUPLE OF DAYS. THERE WILL BE A
WEAK DISTURBANCE THAT WILL PRODUCE BREEZY CONDITIONS OVER THE
COLUMBIA RIVER GORGE AREA ON THURSDAY. WITH THE RIDGE IN PLACE AND
LOW HUMIDITIES IT WILL NOT TAKE MUCH WIND TO REACH CRITICAL FIRE
WEATHER CONDITIONS...THEREFORE A FIRE WEATHER WATCH IS IN EFFECT
FOR OR/WA639. BY FRIDAY A SURFACE LOW WILL SET UP EAST OF THE
CASCADES AND STRONG PRESSURE GRADIENTS WILL ALLOW FOR CONTINUED
WINDY CONDITIONS...THIS TIME EXPANDING INTO THE
OR610...OR640...AND OR641 AREAS. EXPECT THESE CONDITIONS TO
PERSIST THROUGH SATURDAY EVENING. WEBER

.SHORT TERM...MORNING UPDATE...A WEAK DISTURBANCE WILL MOVE INTO AND
THROUGH BRITISH COLUMBIA TODAY AND TONIGHT. THIS DISTURBANCE WILL
SUPPRESS THE STRONG UPPER RIDGE OVER THE WESTERN U.S. SUCH THAT THE
FLOW OVER THE PACIFIC NORTHWEST WILL BE WESTERLY THOUGH TONIGHT.
THUS WILL SEE FAIR AND DRY CONDITIONS OVER THE AREA TODAY AND
TONIGHT. WILL BE ENOUGH INSTABILITY FOR SOME AFTERNOON/EVENING
CUMULUS CLOUDS OVER THE HIGHER TERRAIN, ESPECIALLY OVER THE WALLOWAS
AND THE WASHINGTON CASCADE EAST SLOPES. THERE SHOULD BE SUFFICIENT
CAPPING IN THESE AREAS THIS AFTERNOON/EVENING TO KEEP THESE CUMULUS
CLOUDS FROM DEVELOPING INTO THUNDERSTORMS. HIGH TEMPS WILL BE
WARMEST IN THE LOWER BASIN OF WASHINGTON, BUT GENERALLY WILL BE 103
DEGREES OR LESS. THUS THE CURRENT HEAT ADVISORY IS MARGINAL, BUT
WILL REMAIN IN EFFECT. UPDATES THIS MORNING CENTERED ON MAKING A FEW
ADJUSTMENTS TO WINDS, SKY COVER AND HIGH TEMPS. 90

.LONG TERM...PREVIOUS DISCUSSION...A WEAK AND FLAT MID/UPPER LEVEL
RIDGE OF HIGH PRESSURE WILL BE OVER THE REGION THURSDAY NIGHT. THE
RIDGE WILL GRADUALLY RECEDE SOUTHWARD IN RESPONSE TO A RIDGE
BUILDING UPSTREAM IN THE GULF OF ALASKA FRIDAY AND SATURDAY WHILE A
LARGE MID/UPPER LEVEL TROUGH DIGS SOUTHEAST ACROSS THE PRAIRIE
PROVINCES OF CANADA. SINKING AIR ALOFT ASSOCIATED WITH THE RIDGE
WILL PRODUCE DRY AND STABLE CONDITIONS THROUGH SATURDAY NIGHT. THE
MODELS SHOWS SUBTLE DIFFERENCES IN TERMS OF THE STRENGTH OF THE
RIDGE OVER THE GREAT BASIN AND THE SOUTHWEST STATES. THE 00Z ECMWF
RUN KEEPS WEAK TROUGH OVER WESTERN CANADA AND THIS KEEPS THE RIDGE
OVER THE WESTERN STATES SUPPRESSED FARTHER SOUTH THAN THE 00Z GFS
RUN INDICATES FOR SUNDAY THROUGH MONDAY NIGHT. THE GFS MODEL ALLOWS
THE RIDGE TO BUILD A TAD FARTHER NORTH INTO OREGON, WHICH RESULTS IN
A MONSOON MOISTURE PLUME ADVANCING NORTHWARD OVER CALIFORNIA
RESULTING IN MID LEVEL MOISTURE ENTERING SOUTHERN AND CENTRAL OREGON
BY LATE SATURDAY AFTERNOON WITH THE INFLUX OF MONSOON MOISTURE
CONTINUING INTO SUNDAY AND MONDAY. I CHOSE TO GO WITH THE GFS
SOLUTION. AS SUCH I HAVE A SLIGHT CHANCE OF AFTERNOON AND EVENING
THUNDERSTORMS IN CENTRAL AND NORTHEAST OREGON FOR SUNDAY AND MONDAY.

.SHORT TERM...TODAY THROUGH THURSDAY...A FLAT RIDGE OF HIGH PRESSURE
WILL PERSIST OVER THE REGION TODAY WITH A DRY AND STABLE WESTERLY

TEMPERATURES FROM GETTING TOO HOT. HIGH TEMPERATURES SHOULD BE A

SATURDAY NIGHT. THE MODELS SHOWS SUBTLE DIFFERENCES IN TERMS OF THE
STRENGTH OF THE RIDGE OVER THE GREAT BASIN AND THE SOUTHWEST STATES.
THE 00Z ECMWF RUN KEEPS WEAK TROUGH OVER WESTERN CANADA AND
THIS KEEPS THE RIDGE OVER THE WESTERN STATES SUPPRESSED FARTHER
SOUTH THAN THE 00Z GFS RUN INDICATES FOR SUNDAY THROUGH MONDAY
NIGHT. THE GFS MODEL ALLOWS THE RIDGE TO BUILD A TAD FARTHER NORTH
INTO OREGON, WHICH RESULTS IN A MONSOON MOISTURE PLUME ADVANCING
NORTHWARD OVER CALIFORNIA RESULTING IN MID LEVEL MOISTURE ENTERING
SOUTHERN AND CENTRAL OREGON BY LATE SATURDAY AFTERNOON WITH THE
INFLUX OF MONSOON MOISTURE CONTINUING INTO SUNDAY AND MONDAY. I
CHOSE TO GO WITHT THE GFS SOLUTION. AS SUCH I HAVE A SLIGHT CHANCE
OF AFTERNOON AND EVENING THUNDERSTORMS IN CENTRAL AND NORTHEAST
OREGON FOR SUNDAY AND MONDAY.  POLAN

LEVEL MOISTURE ALONG PORTIONS OF CENTRAL AND NORTHEAST OREGON ON
WEDNESDAY AND THURSDAY...BUT NOT ENOUGH CONFIDENCE TO ADD THUNDER
INTO THE FORECAST.  WEBER

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...EC/GFS AGREE ON RIDGE
FLATTENING BY FRIDAY...BUT DISAGREE ON SOLUTION OVER THE WEEKEND.
GFS REBUILDS RIDGE WITH SOME MOISTURE MOVING NORTH INTO CENTRAL
OREGON ON WEST SIDE OF RIDGE.  ECMWF GOES WITH A DRIER WEST TO
NORTHWEST FLOW OVER THE WEEKEND LIFTING NORTH EARLY NEXT WEEK.  FOR
NOW WITH GO WITH PERSISTENT ABOVE NORMAL TEMPERATURES AND KEEP LOW
RAIN CHANCES CONFINED TO THE EASTERN OREGON MOUNTAINS.

&&

.AVIATION...PREVIOUS DISCUSSION...18Z TAFS...VFR CONDITIONS TO
PREVAIL. ONLY ISOLATED THUNDERSTORMS EXPECTED UNTIL FROM KPSC AND
KPDT AND EAST TIL 02Z. INCREASING WESTERLY FLOW WILL BRING DRIER AND
MORE STABLE CONDITIONS.

&&

.FIRE WEATHER...THE RED FLAG WARNINGS IN EFFECT FOR THE LOWER
COLUMBIA BASIN  WILL LIKELY END AT 4 PM AS ONLY ISOLATED SHOWERS
REMAIN AND WINDS ARE NOT GUSTY TO WARRANT A WIDEPSREAD RED FLAG
WARNING.  THE WARNING FOR THE BLUE MOUNTAINS AND WALLOWA COUNTY WILL
CONTINUE THROUGH THIS EVENING.  ACTIVITY HAS WOUND DOWN IN THE JOHN
DAY REGION AND I WILL SOON MAKE A DECISION TO KEEP THIS GOING
THROUGH THE EVENING OR CANCEL DURING THE AFTERNOON PACKAGE.
OVERALL...NO MAJOR FIRE WEATHER CONCERNS ARE ANTICIPATED TUESDAY
THROUGH THE END OF THE WORK WEEK.  IT WILL BE HOT WITH LOW
RH`S...BOTH DAYTIME AND NIGHTTIME.  THERE WILL BE SOME LINGERING
MOISTURE AND INSTABILITY IN THE WALLOWAS ON TUESDAY THAT COULD
CONTRIBUTE TO CUMULUS BUILDUPS...BUT I CANNOT RULE OUT A
THUNDERSTORM IN THE HIGHER TERRAIN AS WELL.  IF THE GFS
VERIFIES...THERE MAY BE THUNDERSTORMS IN CENTRAL OREGON ON SUNDAY.

PROBLEMS WITH RAPID FIRE SPREAD FOR ANY NEW AND EXISTING FIRES.
SCATTERED THUNDERSTORMS WILL REDEVELOP FROM THE BLUE MOUNTAINS EAST

THUNDERSTORMS WILL LINGER OVER OUR EASTERN MOST ZONES IN THE
EVENING. LOCALLY BREEZY WINDS WILL BE POSSIBLE AT TIMES DUE TO
INCREASING ONSHORE FLOW, ESPECIALLY THROUGH THE CASCADE GAPS. THIS
ONSHORE FLOW WILL CAUSE HIGH TEMPS TO COOL, ESPECIALLY IN THE BASIN
WHERE TEMPS WILL ABOUT 10 DEGREES COOLER THIS AFTERNOON. ANOTHER

INFLUENCE OF THE BASIN HIGH SUPPRESSED SOUTH OF THE CWA. THE UPPER

PACIFIC NORTHWEST AND WESTERN CANADA THROUGH SUNDAY NIGHT. SINKING
AIR ALOFT ASSOCIATED WITH THE HIGH PRESSURE WILL RESULT IN DRY AND

NATIONAL WEATHER SERVICE PENDLETON OR
359 PM PDT SUN JUN 28 2015

UPDATED THE AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH WEDNESDAY EVENING...WILL EXTEND THE
HEAT ADVISORIES FOR MOST OF OUR BASIN ZONES THROUGH MONDAY EVENING.
THIS EXTENSION IS DUE TO THE IMPACTS OF EXPECTED VERY WARM OVERNIGHT
LOW TEMPS. MOST LOCATIONS IN THE BASIN WILL SEE OVERNIGHT LOWS IN
THE 70S.

AN UPPER LEVEL DISTURBANCE WILL MOVE INTO AND ACROSS THE PACIFIC
NORTHWEST DURING THE NEXT 24 HOURS. THIS SYSTEM WILL CONTINUE TO TAP
THE HOT, UNSTABLE AND INCREASINGLY MOIST AIR MASS OVER THE REGION
RESULTING IN THUNDERSTORMS AND SHOWERS. SHOWERS AND STORMS HAVE THE
POTENTIAL TO AFFECT ANY LOCATION WITHIN OUR AREA THROUGH TONIGHT.
SOME STORMS HAVE THE POTENTIAL TO PRODUCE STRONG GUSTY WINDS THROUGH
THIS EVENING. SPC CONTINUES TO HAVE THE WESTERN TWO THIRDS OF OUR
AREA WITHIN A MARGINAL CHANCE OF SEVERE AREA. ON MONDAY THE CHANCES
OF SHOWERS WILL DECREASE FROM THE WEST THROUGH THE DAY AS THE
DISTURBANCE SHIFTS EAST ACROSS THE REGION. BY MONDAY AFTERNOON THE
BEST COVERAGE OF SHOWERS AND STORMS WILL BE FROM THE BLUE MOUNTAINS
EAST TO WALLOWA COUNTY. COULD SEE A FEW SHOWERS AND STORMS LINGER
OVER OUR EASTERN MOST ZONES INTO MONDAY EVENING. LOCALLY BREEZY
WINDS WILL BE POSSIBLE AT TIMES DUE TO INCREASING ONSHORE FLOW,
ESPECIALLY THROUGH THE CASCADE GAPS TONIGHT THROUGH MONDAY EVENING.
THIS ONSHORE FLOW WILL CAUSE HIGH TEMPS TO COOL, ESPECIALLY IN THE
BASIN WHERE TEMPS SHOULD BE AROUND 10 DEGREES COOLER. THE UPPER
RIDGE WILL BE SUPPRESSED SOUTH OF THE PACNW ON TUESDAY, THEN BEGIN
TO BUILD NORTH INTO THE AREA WEDNESDAY. TEMPS WILL REMAIN ABOVE
SEASONAL, BUT NOT AS WARM THIS WEEKEND. ALSO EXPECT DRY CONDITIONS
ACROSS THE AREA AS MOISTURE WILL REMAIN SUPPRESSED OVER SOUTHERN
OREGON AND NEVADA. 90

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...A STRONG HIGH PRESSURE
SYSTEM OVER NEVADA WILL REMAIN STATIONARY AND CONTINUE TO DOMINATE
THE AREAS WEATHER WITH ABOVE NORMAL TEMPERATURES AND MAINLY DRY
CONDITIONS FOR THE REMAINDER OF THE WEEK. ALTHOUGH THE HIGH PRESSURE
SLIPS SOMEWHAT EAST NEXT WEEKEND IT WILL RETAIN A FIRM GRIP ON OUR
AREAS WEATHER AS AFTN HIGH TEMPS REMAIN HOT WITH THE DRY CONDITIONS
PERSISTING.

&&

.AVIATION...A FEW THUNDERSTORMS WILL NEAR TAF SITES KPDT...KALW...
KPSC AND ALSO KRDM AND KBDN THROUGH 04Z THAT WILL LOWER CEILINGS
TOWARD 5K BUT VFR CONDITIONS SHOULD PREVAIL. AFTER 04Z TSRA COULD
ALSO APPROACH KDLS AND KYKM AND LOWER CEILINGS TOWARD 5K WITH MAINLY
VFR CONDITIONS. IN ADDITION BRIEF WIND GUSTS TO 30 KTS ARE POSSIBLE
AT TAF SITE KDLS UNTIL 06S. OTHERWISE THE TAF SITES SHOULD REMAIN
MOSTLY WITH VFR CONDITIONS INTO TOMORROW.

&&

.FIRE WEATHER...ALL ZONES ARE CURRENTLY UNDER A RED FLAG WARNING.
ISOLATED THUNDERSTORMS HAVE DEVELOPED OVER THE SOUTHERN BLUE
MOUNTAINS THIS AFTERNOON...AND SCATTERED THUNDERSTORMS WILL DEVELOP
IN THE NEXT SEVERAL HOURS ALONG THE EAST SLOPES OF THE
CASCADES...THE OCHOCO MOUNTAINS...THE BLUE MOUNTAINS...AND ALONG THE
OREGON BLUE MOUNTAIN FOOTHILLS.  THE DEEPEST VERTICAL SHEAR WILL BE
ALONG THE EAST SLOPES OF THE OREGON AND SOUTHERN WASHINGTON
CASCADES AND CENTRAL OREGON WHERE A LAL OF 4 IS EXPECTED. AREAS EAST
OF THE BLUE MOUNTAINS AND NORTH OF MOUNT ADAMS WILL SEE
THUNDERSTORMS DEVELOP LATER IN THE EVENING.  THE HRRR MODEL HAS BEEN
CONSISTENTLY DEPICTING AN OUTFLOW BOUNDARY OVER CENTRAL OREGON
MOVING NORTH TOWARDS THE WASHINGTON COLUMBIA BASIN THIS EVENING.
DUE TO CONCERNS ABOUT THE POTENTIAL FOR THIS OUTFLOW BOUNDARY TO
DEVELOP AND POSSIBLY REGENERATE THUNDERSTORMS ALONG ITS PATH...I
EXTENDED THE WARNING TO INCLUDE ALL OF OUR WASHINGTON COLUMBIA BASIN
ZONES.  THOSE BATTLING THE SOUTHEAST BENTON COMPLEX FIRE SHOULD BE
PREPARED FOR SUDDEN AND ERRATIC WIND GUSTS THIS EVENING. POST
FRONTAL WINDS THIS EVENING AND ON MONDAY WILL BE AROUND 10-20 MPH
FOR MOST OF THE AREA (20-30 MPH IN THE EASTERN COLUMBIA RIVER GORGE
AND THE KITTITAS VALLEY).  ANY NEW FIRE STARTS WILL HAVE THE
POTENTIAL FOR RAPID SPREAD AS WINDS INCREASE. WISTER

NATIONAL WEATHER SERVICE PENDLETON OR
359 PM PDT SUN JUN 28 2015

UPDATED THE AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH WEDNESDAY EVENING...WILL EXTEND THE
HEAT ADVISORIES FOR MOST OF OUR BASIN ZONES THROUGH MONDAY EVENING.
THIS EXTENSION IS DUE TO THE IMPACTS OF EXPECTED VERY WARM OVERNIGHT
LOW TEMPS. MOST LOCATIONS IN THE BASIN WILL SEE OVERNIGHT LOWS IN
THE 70S.

AN UPPER LEVEL DISTURBANCE WILL MOVE INTO AND ACROSS THE PACIFIC
NORTHWEST DURING THE NEXT 24 HOURS. THIS SYSTEM WILL CONTINUE TO TAP
THE HOT, UNSTABLE AND INCREASINGLY MOIST AIR MASS OVER THE REGION
RESULTING IN THUNDERSTORMS AND SHOWERS. SHOWERS AND STORMS HAVE THE
POTENTIAL TO AFFECT ANY LOCATION WITHIN OUR AREA THROUGH TONIGHT.
SOME STORMS HAVE THE POTENTIAL TO PRODUCE STRONG GUSTY WINDS THROUGH
THIS EVENING. SPC CONTINUES TO HAVE THE WESTERN TWO THIRDS OF OUR
AREA WITHIN A MARGINAL CHANCE OF SEVERE AREA. ON MONDAY THE CHANCES
OF SHOWERS WILL DECREASE FROM THE WEST THROUGH THE DAY AS THE
DISTURBANCE SHIFTS EAST ACROSS THE REGION. BY MONDAY AFTERNOON THE
BEST COVERAGE OF SHOWERS AND STORMS WILL BE FROM THE BLUE MOUNTAINS
EAST TO WALLOWA COUNTY. COULD SEE A FEW SHOWERS AND STORMS LINGER
OVER OUR EASTERN MOST ZONES INTO MONDAY EVENING. LOCALLY BREEZY
WINDS WILL BE POSSIBLE AT TIMES DUE TO INCREASING ONSHORE FLOW,
ESPECIALLY THROUGH THE CASCADE GAPS TONIGHT THROUGH MONDAY EVENING.
THIS ONSHORE FLOW WILL CAUSE HIGH TEMPS TO COOL, ESPECIALLY IN THE
BASIN WHERE TEMPS SHOULD BE AROUND 10 DEGREES COOLER. THE UPPER
RIDGE WILL BE SUPPRESSED SOUTH OF THE PACNW ON TUESDAY, THEN BEGIN
TO BUILD NORTH INTO THE AREA WEDNESDAY. TEMPS WILL REMAIN ABOVE
SEASONAL, BUT NOT AS WARM THIS WEEKEND. ALSO EXPECT DRY CONDITIONS
ACROSS THE AREA AS MOISTURE WILL REMAIN SUPPRESSED OVER SOUTHERN
OREGON AND NEVADA. 90

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...A STRONG HIGH PRESSURE
SYSTEM OVER NEVADA WILL REMAIN STATIONARY AND CONTINUE TO DOMINATE
THE AREAS WEATHER WITH ABOVE NORMAL TEMPERATURES AND MAINLY DRY
CONDITIONS FOR THE REMAINDER OF THE WEEK. ALTHOUGH THE HIGH PRESSURE
SLIPS SOMEWHAT EAST NEXT WEEKEND IT WILL RETAIN A FIRM GRIP ON OUR
AREAS WEATHER AS AFTN HIGH TEMPS REMAIN HOT WITH THE DRY CONDITIONS
PERSISTING.

&&

.AVIATION...A FEW THUNDERSTORMS WILL NEAR TAF SITES KPDT...KALW...
KPSC AND ALSO KRDM AND KBDN THROUGH 04Z THAT WILL LOWER CEILINGS
TOWARD 5K BUT VFR CONDITIONS SHOULD PREVAIL. AFTER 04Z TSRA COULD
ALSO APPROACH KDLS AND KYKM AND LOWER CEILINGS TOWARD 5K WITH MAINLY
VFR CONDITIONS. IN ADDITION BRIEF WIND GUSTS TO 30 KTS ARE POSSIBLE
AT TAF SITE KDLS UNTIL 06S. OTHERWISE THE TAF SITES SHOULD REMAIN
MOSTLY WITH VFR CONDITIONS INTO TOMORROW.

&&

.FIRE WEATHER...ALL ZONES ARE CURRENTLY UNDER A RED FLAG WARNING.
ISOLATED THUNDERSTORMS HAVE DEVELOPED OVER THE SOUTHERN BLUE
MOUNTAINS THIS AFTERNOON...AND SCATTERED THUNDERSTORMS WILL DEVELOP
IN THE NEXT SEVERAL HOURS ALONG THE EAST SLOPES OF THE
CASCADES...THE OCHOCO MOUNTAINS...THE BLUE MOUNTAINS...AND ALONG THE
OREGON BLUE MOUNTAIN FOOTHILLS.  THE DEEPEST VERTICAL SHEAR WILL BE
ALONG THE EAST SLOPES OF THE OREGON AND SOUTHERN WASHINGTON
CASCADES AND CENTRAL OREGON WHERE A LAL OF 4 IS EXPECTED. AREAS EAST
OF THE BLUE MOUNTAINS AND NORTH OF MOUNT ADAMS WILL SEE
THUNDERSTORMS DEVELOP LATER IN THE EVENING.  THE HRRR MODEL HAS BEEN
CONSISTENTLY DEPICTING AN OUTFLOW BOUNDARY OVER CENTRAL OREGON
MOVING NORTH TOWARDS THE WASHINGTON COLUMBIA BASIN THIS EVENING.
DUE TO CONCERNS ABOUT THE POTENTIAL FOR THIS OUTFLOW BOUNDARY TO
DEVELOP AND POSSIBLY REGENERATE THUNDERSTORMS ALONG ITS PATH...I
EXTENDED THE WARNING TO INCLUDE ALL OF OUR WASHINGTON COLUMBIA BASIN
ZONES.  THOSE BATTLING THE SOUTHEAST BENTON COMPLEX FIRE SHOULD BE
PREPARED FOR SUDDEN AND ERRATIC WIND GUSTS THIS EVENING. POST
FRONTAL WINDS THIS EVENING AND ON MONDAY WILL BE AROUND 10-20 MPH
FOR MOST OF THE AREA (20-30 MPH IN THE EASTERN COLUMBIA RIVER GORGE
AND THE KITTITAS VALLEY).  ANY NEW FIRE STARTS WILL HAVE THE
POTENTIAL FOR RAPID SPREAD AS WINDS INCREASE. WISTER

CASCADES...THE OCHOCO MOUNTAINS...THE BLUE MOUNTAINS...AND ALONG THE
OREGON BLUE MOUNTAIN FOOTHILLS.  THE DEEPEST VERTICAL SHEAR WILL BE
ALONG THE EAST SLOPES OF THE OREGON AND SOUTHERN WASHINGTON
CASCADES AND CENTRAL OREGON WHERE A LAL OF 4 IS EXPECTED. AREAS EAST
OF THE BLUE MOUNTAINS AND NORTH OF MOUNT ADAMS WILL SEE
THUNDERSTORMS DEVELOP LATER IN THE EVENING.  THE HRRR MODEL HAS BEEN
CONSISTENTLY DEPICTING AN OUTFLOW BOUNDARY OVER CENTRAL OREGON
MOVING NORTH TOWARDS THE WASHINGTON COLUMBIA BASIN THIS EVENING.
DUE TO CONCERNS ABOUT THE POTENTIAL FOR THIS OUTFLOW BOUNDARY TO
DEVELOP AND POSSIBLY REGENERATE THUNDERSTORMS ALONG ITS PATH...I
EXTENDED THE WARNING TO INCLUDE ALL OF OUR WASHINGTON COLUMBIA BASIN
ZONES.  THOSE BATTLING THE SOUTHEAST BENTON COMPLEX FIRE SHOULD BE
PREPARED FOR SUDDEN AND ERRATIC WIND GUSTS THIS EVENING. POST
FRONTAL WINDS THIS EVENING AND ON MONDAY WILL BE AROUND 10-20 MPH
FOR MOST OF THE AREA (20-30 MPH IN THE EASTERN COLUMBIA RIVER GORGE
AND THE KITTITAS VALLEY).  ANY NEW FIRE STARTS WILL HAVE THE
POTENTIAL FOR RAPID SPREAD AS WINDS INCREASE. WISTER

CORRECTED SHORT TERM DISCUSSION

.SHORT TERM...MORNING UPDATE...A STRONG UPPER LEVEL HIGH PRESSURE
RIDGE WILL CONTINUE OVER THE WESTERN U.S. TODAY. A WEAK UPPER LOW,
CURRENTLY NEAR 40N/128W, WILL SHIFT TO THE OREGON COAST TONIGHT.
THIS LOW WILL FORCE THE UPPER RIDGE AXIS TO SHIFT EAST OF THE
PACIFIC NORTHWEST OVERNIGHT. FOR TODAY, HIGH TEMPS WILL REMAIN WELL
ABOVE SEASONAL OVER A GOOD PORTION OF THE REGION. THUS WILL CONTINUE
THE CURRENT HEAT ADVISORIES. INCREASING CLOUD COVER WITH SHOWERS AND
THUNDERSTORMS WILL CAUSE HIGH TEMPS OVER CENTRAL OREGON TO COOL SOME
VERSUS SATURDAY AFTERNOON. A WEAK INTRUSION OF MARINE AIR WILL ALSO
BRING SOME COOLING TO THE CENTRAL COLUMBIA RIVER GORGE. THE THREAT
OF THUNDERSTORMS CONTINUES THROUGH TONIGHT DUE TO THE GENERAL HEAT
INDUCED INSTABILITY AND ENERGY AHEAD OF THE APPROACHING UPPER LOW.
MADE SOME ADJUSTMENTS TO TIMING AND COVERAGE OF STORMS TODAY AND
TONIGHT. ALSO ADDED THE MENTION OF GUSTY WINDS WITH THUNDERSTORMS
FOR THIS AFTERNOON AND EVENING. SPC HAS PLACED THE WESTERN HALF OF
OUR AREA WITHIN A MARGINAL SEVERE RISK FOR WIND AND POSSIBLY HAIL.
90

.LONG TERM...PREVIOUS DISCUSSION...A LARGE MID/UPPER LEVEL RIDGE OF
HIGH PRESSURE WILL REMAIN OVER THE GREAT BASIN, THE PACIFIC
NORTHWEST AND WESTERN CANADA THROUGH INDEPENDENCE DAY. SINKING AIR
ALOFT ASSOCIATED WITH THE HIGH PRESSURE WILL RESULT IN DRY AND
STABLE CONDITIONS WITH HIGH TEMPERATURES EACH DAY WELL ABOVE NORMAL.
HIGH TEMPERATURES ON WEDNESDAY WILL BE IN THE 90S AND FOR THURSDAY
THROUGH INDEPENDENCE DAY HIGHS WILL BE IN THE UPPER 90S TO THE LOWER
TRIPLE DIGITS.

.AVIATION...PREVIOUS DISCUSSION...12Z TAFS...VFR CONDITIONS WILL
PREVAIL THROUGH THE FORECAST PERIOD. MOSTLY MID CLOUDS ARE EXPECTED
THROUGH THE PERIOD BUT BY THIS AFTERNOON SCATTERED HIGH BASED
CUMULONIMBUS WILL DEVELOP AROUND THE AREA, ESPECIALLY OVER THE
MOUNTAINS AND INVOF KBDN AND KRDM. THE STORMS WILL MOVE NORTH
THROUGH THE EVENING AND POSSIBLY REACH KPDT AND KALW. WINDS COULD
EXCEED 40 KT NEAR THUNDERSTORMS. OTHERWISE, EXPECT WINDS WILL
INCREASE TO 10 TO 15 KTS WITH HIGHER GUSTS IN THE AFTERNOON.
