AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
320 PM PDT WED APR 16 2014

UPDATED FOR AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH SATURDAY...THE NEXT PACIFIC SYSTEM
CONTINUES TO MOVE EAST ACROSS THE EASTERN PACIFIC THIS AFTERNOON
WITH THE MAIN ENERGY PUSH BETWEEN 45 AND 50 NORTH LATITUDE. WILL
CONTINUE TO SEE WARM AIR ADVECTION TONIGHT, PRODUCING MOSTLY MID AND
HIGH LEVEL CLOUDINESS. LIGHT PRECIP CAN BE EXPECTED AT TIMES ALONG
AND NEAR THE CASCADE CREST, WITH A FEW SPRINKLES POSSIBLE OVER THE
BLUE AND WALLOWA MOUNTAINS. THE CENTER OF THIS NEXT PACIFIC SYSTEM
WILL MOVE INTO CENTRAL BRITISH COLUMBIA THURSDAY. THE SYSTEM`S COLD
FRONT WILL SWING ACROSS THE PACNW LATE THURSDAY MORNING AND THURSDAY
AFTERNOON. AS SUCH, EXPECT MOST AREAS TO SEE PRECIP AS THIS COLD
FRONT MOVES THROUGH THE AREA. THERE MAY BE SOME WEAK INSTABILITY
ALONG THE FRONT LATE THURSDAY AFTERNOON THAT COULD CAUSE STRAY
THUNDERSTORMS. THE PORTION OF OUR AREA THAT MAY BE AFFECTED BY THIS
WEAK INSTABILITY IS SO SMALL I WILL NOT MENTION THUNDER THIS TIME. A
POOL OF COLD AIR ALOFT LOOKS TO SWING ACROSS WASHINGTON THURSDAY
NIGHT. THIS COLD AIR ALOFT MAY HELP KEEP SHOWERS GOING OVER PORTIONS
OF THE AREA, BUT INSTABILITY FOR POTENTIAL THUNDER WILL BE VERY
LIMITED DUE TO NIGHTTIME SURFACE COOLING. UPSLOPE AFFECTS OVER THE
INTERIOR MOUNTAINS WILL BE THE MAIN PRECIP PRODUCER IN OUR AREA
THURSDAY NIGHT. BREEZY WINDS WILL BE POSSIBLE BEHIND THE COLD FRONT
THURSDAY NIGHT. THESE WINDS WILL LAST INTO FRIDAY. PRECIP CHANCES
WILL COME TO AN END FRIDAY MORNING AS DRIER AIR MOVES INTO THE AREA.
WEAK HIGH PRESSURE WILL KEEP THE REGION DRY FRIDAY NIGHT INTO
SATURDAY, THOUGH ANOTHER PACIFIC SYSTEM MAY BEGIN TO PUSH SOME LIGHT
PRECIP TO THE CASCADE CREST AREA LATE SATURDAY AFTERNOON. 90

.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY...WEST TO SOUTHWEST
FLOW WILL SET IN SATURDAY NIGHT THROUGH MONDAY NIGHT AS THE UPPER
LEVEL RIDGE BEGINS TO BREAK DOWN. FLOW WILL START OFF WESTERLY AND
WILL TRANSITION TO SOUTHWEST. PRECIPITATION CHANCES ARE NOT THAT
GREAT THROUGH SUNDAY NIGHT...EXCEPT ALONG THE EAST SLOPES OF THE
WASHINGTON CASCADES. BY MONDAY A LOW PRESSURE SYSTEM OFF THE COAST
WILL SPIN UP MOISTURE WITH THE SOUTHWEST FLOW...INCREASING POPS
ALONG THE NORTHEAST MOUNTAINS...AND BRINGING A SLIGHT CHANCE ACROSS
THE LOWER ELEVATIONS. BY MONDAY EVENING SHOWERS WILL BECOME LIKELY
ALONG THE NORTHEAST MOUNTAINS...AND THERE MAY EVEN BE SOME THUNDER
ASSOCIATED. DUE TO LACK OF MODEL CONSISTENCY...HAVE HELD OFF ON THE
MENTION OF THUNDER IN THE FORECAST. AS THE LOW MOVES OVER THE
FORECAST AREA ON TUESDAY THERE WILL STILL BE A CHANCE FOR
SHOWERS...BUT EXPECT TEMPERATURES TO COOL OFF WITH THE COLD FRONTAL
PASSAGE. OVERALL TEMPERATURES IN THE EXTENDED WILL START OUT IN THE
UPPER 60S TO LOWER 70S ACROSS THE LOWER ELEVATIONS...WITH 50S TO
LOWER 60S MOUNTAINS. THESE TEMPERATURES WILL INCREASE A DEGREE OR
TWO EACH DAY...UNTIL THE COLD FRONT PUSHES THROUGH ON TUESDAY...IN
WHICH THE TEMPERATURES ACROSS THE LOWER ELEVATIONS WILL BE BACK IN
THE LOWER TO MID 60S...WITH UPPER 40S TO UPPER 50S MOUNTAINS. WEBER

.AVIATION...00Z TAFS...VFR CONDITIONS ARE FORECAST FOR THE NEXT 12
HOURS WITH POSSIBLE MVFR CONDITIONS STARTING AT KDLS AND KYKM 12-18
HOURS OUT...FOLLOWED BY THE REST OF THE TAF SITES IN THE LAST 6
HOURS OF THE TAF PERIOD. CIGS WILL RANGE FROM 5000-10,000 FEET AGL
FOR THE REST OF THIS EVENING.  CIGS WILL BEGIN TO LOWER OVERNIGHT
AND INTO THE EARLY MORNING HOURS AS A WARM FRONT...WITH STRATIFORM
PRECIPITATION MAKES ITS WAY ACROSS THE AREA.  EXPECT MVFR CIGS AND
VISIBILITIES FOR THE SECOND HALF OF THE TAF PERIOD.  IFR CONDITIONS
CAN`T BE RULED OUT...BUT CONFIDENCE IS NOT HIGH ENOUGH TO INCLUDE
THEM IN THE TAFS.  WINDS WILL GENERALLY BE 5 TO 15 KNOTS THROUGH THE
PERIOD. WEBER

ADJUST POPS IN A FEW AREAS. POPS WERE INCREASED IN THE BLUE
MOUNTAINS AND DECREASED ACROSS CENTRAL OREGON AND THE JOHN DAY-

914 AM PDT WED APR 16 2014

.SHORT TERM...UPDATE...A WEAK UPPER LEVEL HIGH PRESSURE RIDGE OFF
THE PACIFIC NORTHWEST COAST WILL SLOWLY SHIFT EAST TODAY. AS SUCH A
WEAK WARM FRONT WILL GRADUALLY LIFT NORTH AND NORTHEAST THROUGH THE
REGION. THIS WARM FRONT WILL BRING MOSTLY CLOUDY SKIES WITH LOW END
CHANCES OF PRECIP TO A LARGE PORTION OF OUR AREA. AREAS NEAR AND
JUST EAST OF THE WASHINGTON CASCADE CREST WILL SEE BETTER CHANCES OF
PRECIP. CURRENT FORECAST PACKAGE IS GENERALLY IN GOOD SHAPE. DID
ADJUST POPS IN A FEW AREAS. POPS WERE INCREASED IN THE BLUE
MOUNTAINS AND DECREASED ACROSS CENTRAL OREGON AND THE JOHN DAY-
OCHOCO HIGHLANDS. ADJUSTMENTS WERE ALSO MADE TO SKY COVER, SNOW
LEVELS AND AFTERNOON HIGH TEMPS. 90

.LONG TERM...PREVIOUS DISCUSSION...A FLAT RIDGE WILL PASS OVER
WASHINGTON AND OREGON FRIDAY NIGHT AND SATURDAY...FOLLOWED BY A
SOUTHWEST FLOW ALOFT SUNDAY. SUBSIDENCE FROM THE RIDGE WILL KEEP
TEMPERATURES WARM SATURDAY AND SUNDAY. WEAK IMPULSES MOVING THROUGH
THE SOUTHWEST FLOW MAY TRIGGER A FEW SHOWERS IN THE CASCADES
SATURDAY NIGHT AND SUNDAY. ANOTHER FRONT WILL MOVE THROUGH EASTERN
WASHINGTON AND OREGON SUNDAY NIGHT AND MONDAY WITH SHOWERS OVER MOST
OF THE AREA. MONDAY NIGHT AND TUESDAY THE GFS HAS A CUTOFF LOW
DEVELOPING OVER NORTHERN CALIFORNIA AND ECMWF HAS AN ELONGATED
TROUGH NEAR THE COAST. BOTH OF THESE SOLUTIONS WILL PRODUCE SHOWERS
OVER EASTERN WASHINGTON AND OREGON.

UPDATED AVIATION DISCUSSION

.SHORT TERM...FORECAST ON TRACK AND ONLY MINOR UPDATES WERE MADE TO
POPS THIS EVENING.  EASTERN WA/OR ARE UNDER A NW FLOW ALOFT THIS
EVENING...AND WARM ADVECTION MOISTURE WEST OF THE CASCADES WILL
GRADUALLY SPREAD EASTWARD AND BRING LIGHT PRECIPITATION OVERNIGHT
AND WEDNESDAY.  BECAUSE PRECIPITATION WILL BE SLOW TO DEVELOP IN THE
FORECAST AREA...THE TIMING OF THE POPS REFLECT A SLIGHT CHANCE TO A
CHANCE OF RAIN AND MOUNTAIN SNOW A FEW HOURS LATER THAN THE CURRENT
FORECAST. HIGH PRESSURE WILL SLOWLY BUILD OVER THE PACIFIC NW ON
WEDNESDAY...AND PRECIPITATION WILL TAPER OFF DURING THE DAY.  WINDS
HAVE DECREASED ACROSS THE REGION AND WILL PRIMARILY BE TERRAIN
DRIVEN LATE TONIGHT.  WISTER


&&

.AVIATION...06Z TAFS. VFR CONDITIONS ARE FORECAST FOR THE NEXT 24
HOURS. CLOUDS WILL INCREASE AND CIGS WILL LOWER TO 5000-10,000 FEET
AGL OVERNIGHT...AND THERE WILL BE AREAS OF LIGHT RAIN DEVELOPING
WEDNESDAY...MAINLY NEAR KDLS AND KYKM.  HOWEVER...THE PROBABILITY OF
MVFR OR LESS IS SLIM. THE LOW ALTOCUMULUS/ALTOSTRATUS CLOUDS WILL
REMAIN THROUGH THE DAY AND INTO THE EVENING HOURS.  WINDS 5 TO 15
KNOTS ARE EXPECTED THROUGH THE PERIOD.  WISTER

&&

.PREV DISC... /ISSUED 346 PM PDT TUE APR 15 2014/

SHORT TERM...TONIGHT THROUGH FRIDAY...THERE WILL BE A SLIGHT BREAK
IN THE PRECIPITATION WEDNESDAY NIGHT AHEAD OF A COLD FRONT THAT IS
EXPECTED TO SWEEP ACROSS THE FORECAST AREA THURSDAY AFTERNOON AND
EVENING. THIS SYSTEM LOOKS TO HAVE A HIGH CHANCE OF PRECIPITATION
ASSOCIATED WITH IT DURING THE FRONTAL PASSAGE. SNOW LEVELS WILL
LOWER BEHIND THE FRONT THURSDAY NIGHT BUT PRECIPTATION WILL BE
DECREASING SO AGAIN NOT EXPECTING ANY SIGNIFICANT SNOW CONCERNS.
THERE WILL BE SOME BREEZY WINDS FOLLOWING THE FRONTAL PASSAGE. THIS
SYSTEM EXITS LATE THURSDAY NIGHT AND EARLY EARLY FRIDAY CLEARING
SKIES AND DECREASING PRECIPITATION.

LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...A COLD FRONT WILL EXIT
THE AREA WITH WINDS DIMINISHING FRIDAY NIGHT.  CONDITIONS SHOULD
REMAIN DRY THROUGH MOST OF THE WEEKEND.  HOWEVER WEAK IMPULSES MAY
AFFECT THE EAST SLOPES OF THE CASCADES SATURDAY AND
SUNDAY...ALLOWING FOR BRIEF SHOWER ACTIVITY.  WARM AIR ADVECTION
FROM THE SOUTHWEST AS A WEAK RIDGE REBUILDS WILL ALLOW FOR MILD
TEMPERATURES IN THE UPPER 60S TO MID 70S SATURDAY AND SUNDAY.  THERE
IS A SLIGHT CHANCE FOR SHOWERS ALONG THE MOUNTAINS OF NORTHEAST
OREGON ON SUNDAY EVENING AS WELL.  RIGHT NOW MOISTURE LOOKS TO BE
HOLDING OFF UNTIL THE NIGHT TIME PERIOD...BUT MODELS DO INDICATE THE
POSSIBILITY FOR THUNDERSTORMS.  HAVE NOT MENTIONED THEM IN THE
FORECAST...AS IT`S VERY MARGINAL AND THE INSTABILITY MAY NOT REACH
OUR CWA.   ANOTHER FRONT WILL MOVE THROUGH EASTERN WASHINGTON AND
OREGON SUNDAY NIGHT AND INTO MONDAY WITH SHOWER COVERAGE INCREASING
OVER MOST OF THE AREA.  MONDAY ONWARD...MODELS STRUGGLE WITH
CONTINUITY FOR THE EXTENDED...AS THE BEGINNING OF THE WORK WEEK IS
EXPECTED TO BE UNSETTLED WITH SLIGHTLY COOLER TEMPERATURES AND
BETTER CHANCES FOR PRECIPITATION.  WEBER

GRADUALLY SPREAD EASTWARD AND BRING LIGHT PRECIPITATION OVERNIGHT
AND WEDNESDAY.  BECAUSE PRECIPITATION WILL BE SLOW TO DEVELOP IN THE
FORECAST AREA...THE TIMING OF THE POPS REFLECT A SLIGHT CHANCE TO A
CHANCE OF RAIN AND MOUNTAIN SNOW A FEW HOURS LATER THAN THE CURRENT
FORECAST. HIGH PRESSURE WILL SLOWLY BUILD OVER THE PACIFIC NW ON
WEDNESDAY...AND PRECIPITATION WILL TAPER OFF DURING THE DAY.  WINDS
HAVE DECREASED ACROSS THE REGION AND WILL PRIMARILY BE TERRAIN
DRIVEN LATE TONIGHT.  WISTER

.AVIATION...06Z TAFS. VFR CONDITIONS ARE FORECAST FOR THE NEXT 24
HOURS. CLOUDS WILL INCREASE AND CIGS WILL LOWER TO 5000-10,000 FEET
AGL OVERNIGHT...AND THERE WILL BE AREAS OF LIGHT RAIN DEVELOPING
WEDNESDAY...MAINLY NEAR KDLS AND KYKM.  HOWEVER...THE PROBABILITY OF
MVFR OR LESS IS SLIM. THE LOW ALTOCUMULUS/ALTOSTRATUS CLOUDS WILL

ASSOCIATED WITH IT DURING THE FRONTAL PASSAGE. SNOW LEVELS WILL
LOWER BEHIND THE FRONT THURSDAY NIGHT BUT PRECIPTATION WILL BE
DECREASING SO AGAIN NOT EXPECTING ANY SIGNIFICANT SNOW CONCERNS.
THERE WILL BE SOME BREEZY WINDS FOLLOWING THE FRONTAL PASSAGE. THIS

THE AREA WITH WINDS DIMINISHING FRIDAY NIGHT.  CONDITIONS SHOULD
REMAIN DRY THROUGH MOST OF THE WEEKEND.  HOWEVER WEAK IMPULSES MAY
AFFECT THE EAST SLOPES OF THE CASCADES SATURDAY AND

PRECIPITATION ACROSS THE FORECAST AREA OVERNIGHT AND THEN INCREASE
ON WEDNESDAY MAINLY OVER THE CASCADES AND NORTHEAST OREGON AND
SOUTHEAST WASHINGTON. SNOW LEVELS WILL BE AROUND 5000 FEET OR HIGHER
SO NO REAL SNOW CONCERNS. THERE WILL BE A SLIGHT BREAK IN THE

MOUNTAINS OF NORTHEAST OREGON. TEMPERATURES WILL ALSO RUN 5 TO 15
DEGREES COOLER TODAY COMPARED TO MONDAY. WILL BEGIN TO SEE SOME

PREV DISC... /ISSUED 430 AM PDT TUE APR 15 2014/

SHORT TERM...TODAY THROUGH THURSDAY...AN UNSETTLED WEATHER PATTERN
WILL PREVAIL DURING THE SHORT TERM PERIOD WITH A PROGRESSIVE
WESTERLY FLOW ALOFT. THIS WILL CAUSE MORE FREQUENT WEATHER SYSTEMS
TO CROSS THE REGION AND THE CWA. A COLD FRONT WILL MOVE ACROSS THE
AREA THIS MORNING. MOISTURE IS LIMITED WITH THIS FRONT AND THE MAIN
EFFECTS WILL BE INCREASING WINDS WITH ONLY LIGHT PRECIPITATION
AMOUNTS EXPECTED. IT WILL BECOME BREEZY TO WINDY TODAY THROUGH THIS
EVENING OVER MOST OF THE CWA ALONG WITH COOLER TEMPERATURES. THE
WINDS WILL DIMINISH LATER TONIGHT AS PRESSURE GRADIENTS WEAKEN. WIND
SPEEDS TODAY THROUGH THIS EVENING WILL REMAIN BELOW ADVISORY SPEEDS.
A WETTER WEATHER SYSTEM WILL MOVE INTO THE REGION WITH A WARM FRONT
BEGINNING WEDNESDAY MORNING. DUE TO THIS SYSTEM HAVING MORE ABUNDANT
MOISTURE WILL INCREASE POPS OVER AREAS THAT HAD LOW POPS SUCH AS THE
LOWER COLUMBIA BASIN AND THE ADJACENT VALLEYS FOR TONIGHT AND
WEDNESDAY. ANOTHER WEATHER SYSTEM AND WARM FRONT WILL MOVE ACROSS
THE CWA ON THURSDAY...WHICH WILL BE FOLLOWED QUICKLY BY A COLD
FRONT. THIS SYSTEM WILL HAVE EVEN MORE MOISTURE WITH IT AND HAVE
INCREASED POPS EVERYWHERE TO AT LEAST THE CHANCE CATEGORY. SNOW
LEVELS THROUGH THE SHORT TERM WILL BE HIGH ENOUGH TO CONFINE SNOW
ONLY TO THE HIGHER PEAKS...AND THE LACK OF MOISTURE WILL MEAN LIGHT
SNOW AMOUNTS ANYWAY. THEREFORE WINTER WEATHER HIGHLIGHTS WILL NOT BE
NEEDED. TEMPERATURES WILL BE COOLER TODAY AND THEN WILL WARM A
COUPLE OF DEGREES EACH DAY ON WEDNESDAY AND THURSDAY. THEY WILL BE
AROUND NORMAL TODAY AND WILL WARM TO SLIGHTLY ABOVE NORMAL ON
WEDNESDAY AND THURSDAY. 88

LONG TERM...THURSDAY NIGHT THROUGH MONDAY...A PACIFIC COLD FRONT
WILL MOVE THROUGH EASTERN WASHINGTON AND OREGON THURSDAY NIGHT WITH
WIDESPREAD SHOWERS. SOME OROGRAPHICALLY ENHANCED SHOWERS MAY LINGER
FRIDAY IN THE CASCADES AND THE BLUES AND THE WALLOWA MOUNTAINS. A
FLAT RIDGE WILL PASS OVER EASTERN WASHINGTON AND OREGON SATURDAY...
FOLLOWED BY A SOUTHWEST FLOW ALOFT SUNDAY. WEAK IMPULSES MOVING
THROUGH THE SOUTHWEST FLOW MAY TRIGGER A FEW SHOWERS IN THE CASCADES
SATURDAY NIGHT AND SUNDAY. ANOTHER FRONT WILL MOVE THROUGH EASTERN
WASHINGTON AND OREGON SUNDAY NIGHT AND MONDAY WITH SHOWERS OVER MOST
OF THE AREA. TEMPERATURES WILL BE NEAR TO ABOVE NORMAL THROUGH THE
PERIOD WITH VERY MILD TEMPERATURES EXPECTED FOR THE WEEKEND WITH
HIGH TEMPERATURES EXPECTED TO BE AROUND 10 DEGREES ABOVE NORMAL.

MAINLY THE CASCADE CREST AND A FEW ISOLATED SHOWERS OVER THE
MOUNTAINS OF NORTHEAST OREGON. TEMPERATURES WILL ALSO RUN 5 TO 15
DEGREES COOLER TODAY COMPARED TO MONDAY. WILL BEGIN TO SEE SOME
WARM FRONTAL MOISTURE MOVING ACROSS THE FORECAST AREA OVERNIGHT
RESULTING IN SOME INCREASING PRECIPITATION WITH SNOW LEVELS 4000 TO

430 AM PDT TUE APR 15 2014

UPDATED AVIATION DISCUSSION

.SHORT TERM...TODAY THROUGH THURSDAY...AN UNSETTLED WEATHER PATTERN
WILL PREVAIL DURING THE SHORT TERM PERIOD WITH A PROGRESSIVE
WESTERLY FLOW ALOFT. THIS WILL CAUSE MORE FREQUENT WEATHER SYSTEMS
TO CROSS THE REGION AND THE CWA. A COLD FRONT WILL MOVE ACROSS THE
AREA THIS MORNING. MOISTURE IS LIMITED WITH THIS FRONT AND THE MAIN
EFFECTS WILL BE INCREASING WINDS WITH ONLY LIGHT PRECIPITATION
AMOUNTS EXPECTED. IT WILL BECOME BREEZY TO WINDY TODAY THROUGH THIS
EVENING OVER MOST OF THE CWA ALONG WITH COOLER TEMPERATURES. THE
WINDS WILL DIMINISH LATER TONIGHT AS PRESSURE GRADIENTS WEAKEN. WIND
SPEEDS TODAY THROUGH THIS EVENING WILL REMAIN BELOW ADVISORY SPEEDS.
A WETTER WEATHER SYSTEM WILL MOVE INTO THE REGION WITH A WARM FRONT
BEGINNING WEDNESDAY MORNING. DUE TO THIS SYSTEM HAVING MORE ABUNDANT
MOISTURE WILL INCREASE POPS OVER AREAS THAT HAD LOW POPS SUCH AS THE
LOWER COLUMBIA BASIN AND THE ADJACENT VALLEYS FOR TONIGHT AND
WEDNESDAY. ANOTHER WEATHER SYSTEM AND WARM FRONT WILL MOVE ACROSS
THE CWA ON THURSDAY...WHICH WILL BE FOLLOWED QUICKLY BY A COLD
FRONT. THIS SYSTEM WILL HAVE EVEN MORE MOISTURE WITH IT AND HAVE
INCREASED POPS EVERYWHERE TO AT LEAST THE CHANCE CATEGORY. SNOW
LEVELS THROUGH THE SHORT TERM WILL BE HIGH ENOUGH TO CONFINE SNOW
ONLY TO THE HIGHER PEAKS...AND THE LACK OF MOISTURE WILL MEAN LIGHT
SNOW AMOUNTS ANYWAY. THEREFORE WINTER WEATHER HIGHLIGHTS WILL NOT BE
NEEDED. TEMPERATURES WILL BE COOLER TODAY AND THEN WILL WARM A
COUPLE OF DEGREES EACH DAY ON WEDNESDAY AND THURSDAY. THEY WILL BE
AROUND NORMAL TODAY AND WILL WARM TO SLIGHTLY ABOVE NORMAL ON
WEDNESDAY AND THURSDAY. 88

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...A PACIFIC COLD FRONT
WILL MOVE THROUGH EASTERN WASHINGTON AND OREGON THURSDAY NIGHT WITH
WIDESPREAD SHOWERS. SOME OROGRAPHICALLY ENHANCED SHOWERS MAY LINGER
FRIDAY IN THE CASCADES AND THE BLUES AND THE WALLOWA MOUNTAINS. A
FLAT RIDGE WILL PASS OVER EASTERN WASHINGTON AND OREGON SATURDAY...
FOLLOWED BY A SOUTHWEST FLOW ALOFT SUNDAY. WEAK IMPULSES MOVING
THROUGH THE SOUTHWEST FLOW MAY TRIGGER A FEW SHOWERS IN THE CASCADES
SATURDAY NIGHT AND SUNDAY. ANOTHER FRONT WILL MOVE THROUGH EASTERN
WASHINGTON AND OREGON SUNDAY NIGHT AND MONDAY WITH SHOWERS OVER MOST
OF THE AREA. TEMPERATURES WILL BE NEAR TO ABOVE NORMAL THROUGH THE
PERIOD WITH VERY MILD TEMPERATURES EXPECTED FOR THE WEEKEND WITH
HIGH TEMPERATURES EXPECTED TO BE AROUND 10 DEGREES ABOVE NORMAL.

FAVOR THOSE FROM THE BLUE MOUNTAINS EASTWARD. TO THE WEST, THE CLOUD
COVER ON THE WEST SIDE OF THE CASCADES IS MOSTLY CLOUDY, SO SKIES
LATER TONIGHT MAY BE TOO THICK TO ALLOW MOON VIEWING. WINDS ARE ALSO
SHOWING SIGNS OF INCREASING WITH REDMOND, THE DALLES AND ELLENSBURG
ALL AT 10 TO 20 MPH AT THIS TIME. CURRENT FORECAST SHOWS BREEZY
WINDS LATER TONIGHT AND TOMORROW. SO HAVE MADE NO CHANGES. NUMERICAL
GUIDANCE DOES SHOW ELLENSBURG REACHING WIND ADVISORY LEVELS OF 30 TO

WINDS ALOFT ARE 30 TO 35 MPH, SO DO NOT THINK WINDS WILL RISE ABOVE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
836 PM PDT MON APR 14 2014

.UPDATE...A DRY COLD FRONT IS MOVING THROUGH THE AREA AT THIS TIME
AND THE MAIN IMPACTS ARE BROKEN TO OVERCAST MID AND HIGH CLOUDS AND
INCREASING WINDS. CLOUD COVER HAS BEEN HEAVIER THAN WHAT WE HAVE IN
OUR FORECAST SO HAVE BUMPED SKIES UP FROM MOSTLY CLEAR TO
PARTLY/MOSTLY CLOUDY. THIS MAY NEGATIVELY IMPACT THOSE LOOKING TO
SEE THE LUNAR ECLIPSE LATER TONIGHT THOUGH A BAND OF CLEAR SKIES MAY
FAVOR THOSE FROM THE BLUE MOUNTAINS EASTWARD. TO THE WEST, THE CLOUD
COVER ON THE WEST SIDE OF THE CASCADES IS MOSTLY CLOUDY, SO SKIES
LATER TONIGHT MAY BE TOO THICK TO ALLOW MOON VIEWING. WINDS ARE ALSO
SHOWING SIGNS OF INCREASING WITH REDMOND, THE DALLES AND ELLENSBURG
ALL AT 10 TO 20 MPH AT THIS TIME. CURRENT FORECAST SHOWS BREEZY
WINDS LATER TONIGHT AND TOMORROW. SO HAVE MADE NO CHANGES. NUMERICAL
GUIDANCE DOES SHOW ELLENSBURG REACHING WIND ADVISORY LEVELS OF 30 TO
40 MPH TOMORROW. HOWEVER PRESSURE GRADIENTS AREN`T THAT STRONG AND
WINDS ALOFT ARE 30 TO 35 MPH, SO DO NOT THINK WINDS WILL RISE ABOVE
25 TO 35 MPH THERE. WITH THE HEAVIER SKY COVER TONIGHT HAVE BUMPED
UP TEMPERATURES A DEGREE OR TWO AS WELL. FORECAST UPDATE OUT
SHORTLY. PERRY

.PREV DISC... /ISSUED 205 PM PDT MON APR 14 2014/

SHORT TERM...TONIGHT THROUGH THURSDAY...A DRY COLD FRONT WILL PASS
OVER THE FORECAST AREA THIS EVENING FOLLOWED BY AN UPPER LEVEL
TROUGH PASSAGE ON TUESDAY. NO PRECIPITATION IS EXPECTED WITH THE
FRONT BUT IT WILL INCREASE THE WEST TO EAST PRESSURE GRADIENT
BRINGING ABOUT BREEZY CONDITIONS OVERNIGHT AND INTO TUESDAY.
PRECIPITATION CHANCE WILL INCREASE TUESDAY ASSOCIATED WITH THE UPPER
LEVEL TROUGH PASSAGE BUT MAINLY FOR THE CASCADE MOUNTAINS AND OVER
THE NORTHEAST OREGON MOUNTAINS. MAX TEMPERATURES WILL BE 10 TO 15
DEGREES COOLER ON TUESDAY. TUESDAY NIGHT AND WEDNESDAY WE WILL
REMAIN UNDER A COOL MOIST NORTHWEST FLOW WHICH WILL KEEP THE THREAT
OF SHOWERS OVER THE MOUNTAINS. A BRIEF RIDGE OF HIGH PRESSURE WILL
TRANSIT OVER THE AREA WEDNESDAY NIGHT FOLLOWED BY ANOTHER COLD
FRONTAL PASSAGE THURSDAY AFTERNOON. THIS FRONT APPEARS IT WILL HAVE

SHORT TERM...TONIGHT THROUGH WEDNESDAY. STRONG RIDGE OVER THE AREA
TONIGHT. VERY DRY AIRMASS AND DIMINISHING WINDS AFTER SUNSET WILL
ALLOW FOR A COLD NIGHT. MOST LOCATIONS WILL BE IN THE 20S TO LOWER
30S. THE RIDGE WILL BRING A SUNNY WARM DAY MONDAY WITH HIGHS IN THE
60S TO MID 70S. HIGH CLOUDS WILL START TO INCREASE LATE IN THE DAY
WITH AN APPROACHING TROUGH. THIS SYSTEM WILL MOVE THROUGH MONDAY
NIGHT INTO TUESDAY WITH MOSTLY CLOUDY SKIES. NOT EXPECTING MUCH
PRECIPITATION. MAINLY SOME SHOWERS OVER THE CASCADES AND BLUES WITH
A NORTHWEST FLOW ALOFT. PRESSURE GRADIENTS WILL PRODUCE BREEZY
WESTERLY WINDS MONDAY NIGHT INTO TUESDAY. AS THIS FIRST SYSTEM MOVES
OFF TO THE EAST WEDNESDAY HEIGHTS WILL BUILD A LITTLE. THIS WILL
RESULT IN LESS CLOUDS AND SHOWERS ALONG WITH WARMER TEMPERATURES AND
LIGHTER WINDS. 94

LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...AN UPPER LEVEL RIDGE
OF HIGH PRESSURE WILL DOMINATE THE WEATHER ACROSS THE INTERIOR
PACIFIC NORTHWEST WEDNESDAY NIGHT FOR WIDESPREAD SINKING AIR MOTION
RESULTING IN DRY CONDITIONS.

AN UPPER TROUGH OFF THE COAST AND THE AFOREMENTIONED RIDGE WILL EASE
ON EASTWARD DURING THE DAY ON THURSDAY THUS ALLOWING FLOW ALOFT TO
BACK FROM THE WEST TO THE SOUTHWEST ALLOWING INCREASING MOISTURE TO
MOVE INTO THE REGION FOR INCREASING POPS ALONG THE EAST SLOPES OF
THE CASCADES BY THURSDAY AFTERNOON. THURSDAY NIGHT/FRIDAY THE TROUGH
SWINGS ACROSS THE FORECAST AREA FOR RAIN LIKELY IN MOUNTAINS AND A
CHANCE OF RAIN AT LOWER ELEVATIONS WITH SNOW LEVELS 5000-6000 FEET.
FRIDAY NIGHT THE TROUGH MOVES INTO IDAHO FOR DECREASING POPS.
