AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
300 AM PST WED MAR 4 2015

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...A PRONOUNCED UPPER LEVEL
RIDGE OFF THE WEST COAST OFF NORTH AMERICA WILL TRANSLATE ESEWD AND
BE CENTERED OVER CALIFORNIA BY EARLY SATURDAY MORNING. THIS WILL
RESULT IN A QUITE BENIGN WEATHER PATTERN FOR THE INLAND NW THE NEXT
FEW DAYS. AFTER A VERY COLD START TEMPERATURES WILL WARM NICELY THIS
AFTERNOON WITH HIGHS IN THE 50S...40S MOUNTAINS. IT WILL BE COLD
AGAIN TONIGHT AND NUDGED FORECAST TEMPERATURES DOWN A BIT IN LINE
WITH LATEST GUIDANCE TO MOSTLY LOWER 20S WITH TEENS MOUNTAINS. ON
THURSDAY IT WILL BE WARMER IN THE AFTERNOON WITH HIGHS MID TO UPPER
50S LOWER ELEVATIONS AND NEAR 50 MOUNTAINS. MODELS ARE HINTING AT A
FEW HIGH CLOUDS LATER THURSDAY THROUGH FRIDAY NIGHT ESPECIALLY
CENTRAL AND NORTH. THIS WILL HELP KEEP TEMPERATURES UP THURSDAY
NIGHT TO AROUND 30 LOWER ELEVATIONS WITH 20S MOUNTAINS. FRIDAY WILL
BE A VERY NICE DAY EXCEPT FOR A FEW HIGH CLOUDS WITH AFTERNOON HIGHS
IN THE LOWER ELEVATIONS REACHING THE LOWER 60S. WITH SOME CLOUDS
FRIDAY NIGHT TEMPERATURES WILL BE MOSTLY IN THE 30S. WINDS WILL BE
LIGHT THROUGH THE PERIOD. 78

.LONG TERM...SATURDAY THROUGH TUESDAY NIGHT...A MID/UPPER LEVEL
RIDGE OF HIGH PRESSURE WILL PERSIST OVER THE FORECAST AREA THROUGH
MONDAY NIGHT FOR DRY CONDITIONS. ON MONDAY NIGHT THE GFS MODEL SHOWS
A MID/UPPER LEVEL TROUGH MOVING SOUTHEAST INTO THE RIDGE WHEREAS THE
ECMWF DOES NOT SHOW THIS FEATURE. CONFIDENCE IS NOT AS HIGH AS I
WOULD LIKE IN BRINGING THE TROUGH INTO THE INTERIOR PACIFIC
NORTHWEST GIVEN THE UNUSUAL STRENGTH AND PERSISTENCE OF THE
AFOREMENTIONED RIDGE OVER THE PAST THREE MONTHS. HOWEVER, THE ECMWF
CATCHES UP WITH THE GFS IN TERMS OF BRINGING A LARGER TROUGH INLAND
ON WEDNESDAY. AS SUCH I SPLIT THE DIFFERENCE AS INCREASED POPS FOR
TUESDAY NIGHT IN THE WESTERN SECTIONS OF THE FORECAST AREA BY
PAINTING CHANCE POPS ALONG THE EAST SLOPES OF THE WASHINGTON AND
OREGON CASCADES FOR TUESDAY NIGHT. SNOW LEVELS TUESDAY NIGHT WILL BE
ABOVE 6000 FEET.  POLAN

.AVIATION...12Z TAFS...VFR CONDITIONS WITH GENERALLY CLEAR SKIES ARE
EXPECTED OVER THE NEXT 24 HOURS. WINDS WILL REMAIN LESS THAN 10 KTS.

NATIONAL WEATHER SERVICE PENDLETON OR
523 PM PST MON MAR 2 2015

...UPDATED AVIATION DISCUSSION...

.SHORT TERM...ISSUED AN EARLY FORECAST UPDATE THIS EVENING TO PLACE
THE ENTIRE FORECAST AREA UNDER AT LEAST A SLIGHT CHANCE OF SHOWERS
THROUGH THE EVENING. RADAR AND SATELLITE ARE SHOWING ISOLATED TO
SCATTERED SHOWERS ACROSS THE FORECAST AREA UNDER THIS NORTHERLY
FLOW. NORTHEAST OREGON CONTINUES TO HAVE THE BEST CHANCE OF SHOWERS
ESPECIALLY OVER THE HIGHER TERRAIN AND WALLOWA COUNTY. THESE AREAS
COULD SEE 1 TO 3 INCHES OF SNOW OVERNIGHT. REST OF THE FORECAST AREA
WILL SEE LITTLE TO NO ACCUMULATIONS. SHOWERS WILL BE ON THE DECREASE
AFTER MIDNIGHT.

.AVIATION...VFR CONDITIONS ARE EXPECTED OVER THE NEXT 24 HOURS.
THERE WILL BE SOME SCT-BKN CLOUDS 060-080 MAINLY IMPACTING KRDM AND
KBDN OTHERWISE CLEARING SKIES FOR OTHER SITES. THERE WILL BE SOME
NORTH WINDS 10-20 KNOTS AT KPSC OVERNIGHT DECREASING LATE OTHERWISE
EXPECTING MAINLY LESS THAN 10 KNOTS.

&&

.PREV DISC... /ISSUED 230 PM PST MON MAR 2 2015/

SHORT TERM...TONIGHT THROUGH THURSDAY.  THE TAIL END OF A BACKDOOR
COLD FRONT IS MAKING ITS WAY ACROSS EASTERN WASHINGTON AND NORTHEAST
OREGON.  DOPPLER RADAR AT SPOKANE IS SHOWING A WIDE SWATH OF WEAK
RETURNS (LESS THAN 20 DBZ). LATEST HRRR KEEP REFLECTIVITIES THIS LOW
THROUGH EARLY TUESDAY MORNING WITH 12-HOUR QPF AMOUNTS LESS THAN A
TENTH OVER MOST OF THE AREA. THIS INCREASES CONFIDENCE THAT ANY
SNOWFALL TONIGHT WILL BE LIGHT AND MAINLY ISOLATED TO SCATTERED
OROGRAPHIC SHOWERS.  THE ONE EXCEPTION WILL BE OVER THE WALLOWA
MOUNTAINS WHERE A NORTHERLY FLOW ALOFT AND MOISTURE WILL BRING 3-6
INCHES OF SNOW IN THE HIGHER TERRAIN.  THE WALLOWA VALLEY...IMNAHA
VALLEY...AND THE NORTHERN PLATEAU OF WALLOWA COUNTY WILL LIKELY
RECEIVE 1-3 INCHES OVERNIGHT DUE TO THE 20:1 SNOW-TO-LIQUID RATIO
AND LOW LEVEL UPSLOPE. PRECIPITATION WILL TAPER OFF TONIGHT AND
EARLY TUESDAY MORNING.  A DRY NORTHERLY FLOW ALOFT FOLLOWING THE
SYSTEM WILL CAUSE OVERNIGHT TEMPERATURES TONIGHT TO FALL INTO THE
TEENS AND 20S...AND SINGLE DIGITS AND TEENS TUESDAY NIGHT.  IT WILL
BE BREEZY TONIGHT IN THE LOWER COLUMBIA BASIN RESULTING IN WIND
CHILLS IN THE TEENS.  A FEW LOCATIONS MAY BEAT THEIR RECORD LOWS FOR
TUESDAY NIGHT.

A DRY FORECAST IS IN STORE TUESDAY AFTERNOON THROUGH THURSDAY.  A
WARMING TREND BEGINS WEDNESDAY AS HIGH PRESSURE ALOFT BUILDS.
AFTERNOON TEMPERATURES WILL CLIMB INTO THE 50S ACROSS THE REGION ON
THURSDAY--ABOUT 5 DEGREES ABOVE SEASONAL AVERAGE.  WISTER

LONG TERM...THURSDAY NIGHT THROUGH MONDAY. TOWARD THE END OF THE
WEEK A DISTURBANCE WILL PASS TO THE NORTH OF THE AREA AS STRONG HIGH
PRESSURE DOMINATES OUR WEATHER INTO THE WEEKEND WITH DRY CONDITIONS.
AFTERNOON TEMPERATURES ARE FORECAST TO CLIMB ABOVE NORMAL AND INTO
THE 60S ACROSS SOME LOCATIONS BY THE WEEKEND.

AVIATION...LCL MVFR CEILINGS WILL PERSIST INTO THIS EVENING AS A
DISTURBANCE MOVES THROUGH THE REGION. WNW SFC WINDS WILL SHIFT TO
THE NORTH THAT WILL USHER SOME COLDER AIR INTO THE REGION TONIGHT.
DECREASING CLOUDS WILL ACCOMPANY THE COLDER AIR AND A RETURN TO VFR
CONDITIONS ARE EXPECTED AFTER 02Z EXCEPT AFTER 06Z ALONG THE
FOOTHILLS OF THE BLUE MOUNTAINS THAT INCLUDES TAF SITES KPDT AND
KALW. THE VFR CONDITIONS WILL CONTINUE INTO TUESDAY.

NATIONAL WEATHER SERVICE PENDLETON OR
537 PM PST MON MAR 2 2015

.SHORT TERM...ISSUED AN EARLY FORECAST UPDATE THIS EVENING TO PLACE
THE ENTIRE FORECAST AREA UNDER AT LEAST A SLIGHT CHANCE OF SHOWERS
THROUGH THE EVENING. RADAR AND SATELLITE ARE SHOWING ISOLATED TO
SCATTERED SHOWERS ACROSS THE FORECAST AREA UNDER THIS NORTHERLY
FLOW. NORTHEAST OREGON CONTINUES TO HAVE THE BEST CHANCE OF SHOWERS
ESPECIALLY OVER THE HIGHER TERRAIN AND WALLOWA COUNTY. THESE AREAS
COULD SEE 1 TO 3 INCHES OF SNOW OVERNIGHT. REST OF THE FORECAST AREA
WILL SEE LITTLE TO NO ACCUMULATIONS. SHOWERS WILL BE ON THE DECREASE
AFTER MIDNIGHT.

&&

.PREV DISC... /ISSUED 230 PM PST MON MAR 2 2015/

SHORT TERM...TONIGHT THROUGH THURSDAY.  THE TAIL END OF A BACKDOOR
COLD FRONT IS MAKING ITS WAY ACROSS EASTERN WASHINGTON AND NORTHEAST
OREGON.  DOPPLER RADAR AT SPOKANE IS SHOWING A WIDE SWATH OF WEAK
RETURNS (LESS THAN 20 DBZ). LATEST HRRR KEEP REFLECTIVITIES THIS LOW
THROUGH EARLY TUESDAY MORNING WITH 12-HOUR QPF AMOUNTS LESS THAN A
TENTH OVER MOST OF THE AREA. THIS INCREASES CONFIDENCE THAT ANY
SNOWFALL TONIGHT WILL BE LIGHT AND MAINLY ISOLATED TO SCATTERED
OROGRAPHIC SHOWERS.  THE ONE EXCEPTION WILL BE OVER THE WALLOWA
MOUNTAINS WHERE A NORTHERLY FLOW ALOFT AND MOISTURE WILL BRING 3-6
INCHES OF SNOW IN THE HIGHER TERRAIN.  THE WALLOWA VALLEY...IMNAHA
VALLEY...AND THE NORTHERN PLATEAU OF WALLOWA COUNTY WILL LIKELY
RECEIVE 1-3 INCHES OVERNIGHT DUE TO THE 20:1 SNOW-TO-LIQUID RATIO
AND LOW LEVEL UPSLOPE. PRECIPITATION WILL TAPER OFF TONIGHT AND
EARLY TUESDAY MORNING.  A DRY NORTHERLY FLOW ALOFT FOLLOWING THE
SYSTEM WILL CAUSE OVERNIGHT TEMPERATURES TONIGHT TO FALL INTO THE
TEENS AND 20S...AND SINGLE DIGITS AND TEENS TUESDAY NIGHT.  IT WILL
BE BREEZY TONIGHT IN THE LOWER COLUMBIA BASIN RESULTING IN WIND
CHILLS IN THE TEENS.  A FEW LOCATIONS MAY BEAT THEIR RECORD LOWS FOR
TUESDAY NIGHT.

A DRY FORECAST IS IN STORE TUESDAY AFTERNOON THROUGH THURSDAY.  A
WARMING TREND BEGINS WEDNESDAY AS HIGH PRESSURE ALOFT BUILDS.
AFTERNOON TEMPERATURES WILL CLIMB INTO THE 50S ACROSS THE REGION ON
THURSDAY--ABOUT 5 DEGREES ABOVE SEASONAL AVERAGE.  WISTER

LONG TERM...THURSDAY NIGHT THROUGH MONDAY. TOWARD THE END OF THE
WEEK A DISTURBANCE WILL PASS TO THE NORTH OF THE AREA AS STRONG HIGH
PRESSURE DOMINATES OUR WEATHER INTO THE WEEKEND WITH DRY CONDITIONS.
AFTERNOON TEMPERATURES ARE FORECAST TO CLIMB ABOVE NORMAL AND INTO
THE 60S ACROSS SOME LOCATIONS BY THE WEEKEND.

AVIATION...LCL MVFR CEILINGS WILL PERSIST INTO THIS EVENING AS A
DISTURBANCE MOVES THROUGH THE REGION. WNW SFC WINDS WILL SHIFT TO
THE NORTH THAT WILL USHER SOME COLDER AIR INTO THE REGION TONIGHT.
DECREASING CLOUDS WILL ACCOMPANY THE COLDER AIR AND A RETURN TO VFR
CONDITIONS ARE EXPECTED AFTER 02Z EXCEPT AFTER 06Z ALONG THE
FOOTHILLS OF THE BLUE MOUNTAINS THAT INCLUDES TAF SITES KPDT AND
KALW. THE VFR CONDITIONS WILL CONTINUE INTO TUESDAY.

.SHORT TERM...MORNING UPDATE...A DRY NORTHWEST FLOW WILL CONTINUE
ACROSS THE REGION TODAY. A WEAK SYSTEM MOVING SOUTH ALONG THE
BRITISH COLUMBIA COAST WILL APPROACH THE REGION TONIGHT. CONDITIONS
WILL BE FAIR AND DRY TODAY WITH A GRADUAL INCREASE IN HIGH
CLOUDINESS FROM THE NORTHWEST THIS AFTERNOON. THE B.C. SYSTEM STILL
LOOKS TO DRIVE SOUTH ALONG THE PACIFIC NORTHWEST COAST TONIGHT. THUS
ONLY EXPECT SOME LIGHT PRECIP ALONG AND JUST EAST OF THE CASCADE
CREST. OVERALL CURRENT FORECAST PACKAGE HANDLES THESE TRENDS.
UPDATES THIS MORNING INCLUDED ADJUSTMENTS TO WINDS THROUGH TONIGHT,
SOME AFTERNOON HIGH TEMPS, AND TO THE SKY COVER FOR TODAY. 90

.LONG TERM...PREVIOUS DISCUSSION...HIGH PRESSURE ALOFT WILL DOMINATE
THE WEATHER TUESDAY NIGHT THROUGH THURSDAY MORNING WITH A COOL AND
DRY NORTH TO NORTHWEST FLOW ALOFT. A COLD FRONT WITH SOME LIGHT SNOW
SHOWERS WILL EXIT THE REGION TO THE SOUTH ON TUESDAY LEAVING BEHIND
A COLD NORTHERLY FLOW AT FIRST UNDER A BUILDING RIDGE TO THE WEST.
THIS WILL PROVIDE MOSTLY CLEAR COLD NIGHTS WITH MODERATING
TEMPERATURES DURING THE DAY. TUESDAY NIGHT WILL BE THE COLDEST NIGHT
WITH LOW TEMPERATURE READINGS IN THE TEENS AND 20S IN THE LOWER
ELEVATIONS AND SINGLE DIGITS TO TEENS IN THE HIGHER ELEVATIONS.
TEMPERATURES WILL MODERATE WEDNESDAY AND THURSDAY WITH TEMPERATURES
RETURNING TO NEAR TO SLIGHTLY ABOVE NORMAL DURING THE DAY WITH
CONTINUE COLD NIGHTS DUE TO STRONG RADIATIONAL COOLING. THURSDAY
NIGHT ANOTHER PACIFIC COLD FRONT WILL MOVE THROUGH THE REGION BUT
THE AIR BEHIND IT WILL ACTUALLY BE WARMER DUE TO ITS ORIGIN OVER THE
PACIFIC. THERE MAY BE SOME MOUNTAIN SNOW SHOWERS AND VALLEY RAIN
SHOWERS ON FRIDAY. HIGH PRESSURE WILL REBUILD AGAIN BY FRIDAY NIGHT
AND CONTINUE THROUGH THE REST OF THE LONG TERM PERIOD. THERE WILL BE
A WARMING TREND THROUGH THIS SECOND HALF OF THE EXTENDED PERIOD WITH
MAXIMUM TEMPERATURES INCREASING TO THE LOWER 60S VALLEYS AND 50S
MOUNTAINS. NIGHT TIME LOWS WILL INCREASE TO THE 30S AND 40S IN THE
