AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
350 PM PDT THU MAR 29 2012

UPDATED AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...A TROUGH OF LOW
PRESSURE REMAINS OFF THE PACIFIC NORTHWEST COAST WITH MOISTURE
STREAMING INTO THE REGION. SNOW LEVELS ARE ABOVE 5000 FEET IN OREGON
AND ABOVE 3000 FEET IN THE EAST SLOPES OF THE CASCADES OF
WASHINGTON. THESE SNOW LEVELS WILL RISE TONIGHT AS WARMER AIR MOVES
INTO THE REGION. THEREFORE...THE PREDOMINATE PRECIPITATION TYPE WILL
BE RAIN. THIS BAND OF PRECIPITATION WILL REMAIN OVER THE AREA ON
FRIDAY BEFORE LIFTING NORTHWARD AS A WARM FRONT FRIDAY NIGHT. AREAS
UNDER THIS BAND WILL SEE RAIN CONTINUE. THEN...A SHORTWAVE TROUGH
WILL PUSH A COLD FRONT THROUGH THE AREA ON SATURDAY. THIS WILL LEAD
TO AN INCREASED CHANCE OF RAIN AND HIGH ELEVATION SNOW FOR THE AREA
ON SATURDAY. SOME INSTABILITY AHEAD OF THE FRONT MAY LEAD TO A FEW
THUNDERSTORMS TO DEVELOP DURING THE AFTERNOON HOURS ACROSS NORTHEAST
OREGON. THE INSTABILITY PARAMETERS HAVE WEAKENED IN THE MODELS...BUT
THERE IS STILL ENOUGH POTENTIAL TO WARRANT A SLIGHT CHANCE MENTION.
THE TROUGH PUSHES EAST SATURDAY NIGHT WITH SNOW LEVELS DROPPING
RAPIDLY TO AROUND 2000-3000 FEET ACROSS THE AREA.
HOWEVER...PRECIPITATION AMOUNTS WILL BE DECREASING AT THIS TIME SO
SNOW AMOUNTS WILL REMAIN BELOW ADVISORY AMOUNTS. WILL NEED TO
MONITOR THE SITUATION AS MODELS HAVE BEEN TRENDING A BIT SLOWER WITH
THE SYSTEM.

TEMPERATURES WILL REMAIN MILD THROUGH THE SHORT TERM...AND WINDS
WILL BE BREEZY TO LOCALLY WINDY EACH DAY WITH THE DISTURBANCES. THE
MAIN CONCERN WILL BE THE AMOUNT OF PRECIPITATION THAT WILL BE
FALLING AS RAIN AND WILL BE ADDRESSED IN THE HYDROLOGY SECTION. DMH

.LONG TERM...SUNDAY THROUGH THURSDAY...SUNDAY WILL SEE THE LINGERING
EFFECTS OF A DEPARTING WEATHER SYSTEM IN THE FORM OF DECREASING
SHOWERS AND A COOL BREEZY DAY. MODELS AGREE THAT MONDAY AND TUESDAY
WILL SEE THE DEEPENING OF AN UPPER LEVEL TROUGH NEAR THE WEST COAST.
HOWEVER...POSITION OF THIS FEATURE DIFFERS WITH TIME AS THE ECMWF
BEING THE MORE PROGRESSIVE NUDGES A FRONT INTO THE REGION MONDAY
NIGHT AND TUESDAY. THE GFS IS SLOWER AND DELAYS THE FRONT UNTIL
WEDNESDAY. GIVEN THE MODEL DIFFERENCES I TRIED TO GO WITH A MIDDLE
OF THE ROAD SOLUTION WITH LOW CONFIDENCE AT THIS POINT.

&&

.AVIATION...00Z TAFS...CLOUDY AND SHOWERY WEATHER IS EXPECTED
OVERNIGHT WITH SOME DECREASE IN SHOWER ACTIVITY ON FRIDAY. OVERALL
EXPECT MAINLY VFR CONDITIONS BUT WITH OCCASIONAL MVFR AT TIMES DUE
TO LOWERED CEILINGS...THOUGH VISIBILITY MAY ALSO BE REDUCED IN THE
HEAVIER SHOWERS. BREEZY SOUTH WINDS OF 15 TO 25 MPH WILL CONTINUE
OVERNIGHT AT MOST LOCATIONS THEN WILL SWITCH TO SOUTHWEST ON
FRIDAY.

&&

.HYDROLOGY...NUMEROUS DAYS OF RAIN HAVE CAUSED STREAMS AND RIVERS
OVER THE BLUE MOUNTAINS AND WALLOWA COUNTY TO START TO RISE WITH
ANOTHER 48 HOURS OF RAIN AND HIGH SNOW LEVELS EXPECTED BEFORE SNOW
LEVELS DECREASE ON SUNDAY MORNING. RIVER FORECASTS SHOW THE LARGE
RIVERS IN THIS AREA WILL RISE TO BANKFULL OR JUST ABOVE..BUT ARE NOT
EXPECTED TO REACH FLOOD STAGE. SMALL STREAMS WILL ALSO SEE RISES
AND MAY SEE SOME FLOODING STARTING LATE FRIDAY. FLOOD WATCH FOR
THIS AREA WILL BE IN EFFECT THROUGH SUNDAY MORNING. ML
