AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
755 PM PST SUN FEB 8 2015

.SHORT TERM...LARGE UPPER LOW CENTERED OFF THE WEST COAST THIS
EVENING. SATELLITE SHOWS SEVERAL VORTICITY CENTERS ROTATING THROUGH
THE LOW. FRONTAL BAND ACCOMPANIED BY SOME LIGHT PRECIPITATION IS
MOVING NORTH OF THE FORECAST AREA THIS EVENING. MUCH MORE UNSTABLE
BEHIND THIS BOUNDARY WITH PLENTY OF LIGHTNING WEST OF THE CASCADES
THE PAST SEVERAL HOURS. PRECIPITATION WILL BE MORE SHOWERY IN NATURE
FOR THE REMAINDER OF THE NIGHT. ON MONDAY THE LOW MOVES NORTHWARD
AND WEAKENS INTO AN UPPER TROUGH RESULTING IN A WESTERLY FLOW ALOFT.
MODELS CONTINUE TO INDICATE A FAIR AMOUNT OF PRECIPITATION OVER THE
REGION HOWEVER EXPECT MUCH OF THIS WILL BE OVER THE CASCADES.
LOWERING FREEZING LEVELS WILL PRODUCE SNOW OVER THE MOUNTAINS MONDAY
NIGHT. SOUTHERLY WINDS WILL BE INCREASING TONIGHT OVER CENTRAL AND
NORTHEAST OREGON. MOST AREAS WILL HAVE BREEZY SOUTHWEST WINDS
MONDAY. 94

&&

.PREV DISC... /ISSUED 230 PM PST SUN FEB 8 2015/

SHORT TERM...TONIGHT THROUGH WEDNESDAY.  A DEEP CLOSED LOW TRACKING
NORTH ALONG THE OREGON COAST WILL SPREAD PRECIPITATION EAST OF THE
CASCADES TONIGHT.  SNOW LEVELS WILL BE BETWEEN 6500-7500
FEET...THEREFORE THE MOUNTAINS WILL RECEIVE RAIN WITH THE EXCEPTION
OF THE HIGHEST PEAKS.  PRECIPITATION AMOUNTS OF A TENTH TO A QUARTER
OF AN INCH CAN BE EXPECTED OVER MOST OF THE AREA WITH HIGHER AMOUNTS
ALONG THE EAST SLOPES OF THE CASCADES AND THE EAGLE CAPS.  WINDS
ALOFT WILL ALSO INCREASE TONIGHT...AND IT WILL BE VERY WINDY ALONG
MANY RIDGETOPS.  VERY WINDY CONDITIONS ARE ALSO FORECAST FOR THE
SOUTHERN GRANDE RONDE VALLEY THIS EVENING...AND WINDS MAY BRIEFLY
REACH ADVISORY CRITERIA (I.E. GUSTS TO 45 MPH) NEAR LADD AND PYLES
CANYONS.

THE CLOSED LOW WILL WEAKEN INTO AN OPEN TROUGH MONDAY...AND THE
FORECAST AREA WILL BE UNDER A MOIST WESTERLY FLOW MONDAY AND MONDAY
NIGHT.  IT WILL BE BREEZY TO WINDY OVER MOST OF THE AREA. ONE AREA
OF CONCERN FOR WINDS GUSTS IS JUST EAST OF THE OREGON CASCADES WHERE
MOUNTAIN WAVES FORMING ALONG THE RIDGETOPS MAY PROPAGATE TO THE
SURFACE CREATING SUDDEN STRONG WINDS.  ANALYZING THE 12Z AND 18Z
MODELS...I WOULD EXPECT THESE WILL BE TRAPPED LEE WAVES AND WILL NOT
ISSUE ANY WIND HIGHLIGHTS FOR THIS AREA.  SNOW LEVELS WILL LOWER TO
NEAR 4000-4500 FEET MONDAY NIGHT.  THE BLUE MOUNTAINS AND THE
WALLOWA MOUNTAINS ABOVE 4500 FEET MAY SEE 1-3 INCHES OF SNOW BY
TUESDAY MORNING.

THE REMAINDER OF THE SHORT TERM PERIOD WILL BE RELATIVELY QUIET AS
HIGH PRESSURE ALOFT STRENGTHENS OVER WA/OR.  A DRY FORECAST IS IN
STORE TUESDAY NIGHT AND WEDNESDAY.  PATCHY FOG CAN BE EXPECTED OVER
PORTIONS OF THE LOWER COLUMBIA BASIN AND SURROUNDING VALLEYS.  WISTER

LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY. A RIDGE OF HIGH
PRESSURE WILL INFLUENCE OUR AREA BY MIDWEEK WITH MOSTLY DRY
CONDITIONS THROUGH THE END OF THE WORK WEEK. MEANWHILE A WEAK
DISTURBANCE WILL APPROACH THE TWO STATE AREA AND MOVE OVER THE TOP
OF THE RIDGE THURSDAY WHICH COULD PRODUCE A FEW SHOWERS ALONG THE
EAST SLOPES OF THE WA CASCADES. OTHERWISE THE DRY CONDITIONS SHOULD
PERSIST INTO THE WEEKEND. THE EXTENDED MODELS WERE HINTING AT A LOW
PRESSURE SYSTEM OVER CANADA AND THIS IS FORECAST TO MOVE SOUTH WHICH
COULD BRING COOLER TEMPERATURES ALONG WITH PCPN TO OUR REGION LATE
SUNDAY.

AVIATION...00Z. LCL MVFR CEILINGS CAN BE EXPECTED ACROSS TAF SITES
KRDM AND KBDN ESPECIALLY IN SHOWERS BEFORE EXPANDING INTO THE
REMAINDER OF THE AREA AFTER 02Z. A BRIEF RECOVERY TO MOSTLY VFR
CONDITIONS TOWARD 06Z IS EXPECTED BUT A RETURN TO AREAS OF MVFR
CONDITIONS IS LIKELY AFTER 12Z.
