AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
255 PM PST SAT FEB 19 2011

.SHORT TERM...TONIGHT THROUGH MONDAY...THE LOW PRESSURE SYSTEM THAT
HAS BEEN BRINGING SNOW TO PORTIONS OF CENTRAL OREGON TODAY HAS
REACHED THE TRIPLE POINT OF THE OREGON/NEVADA/IDAHO BORDER. THIS
SYSTEM WILL CONTINUE TO MOVE EAST THIS EVENING. AN AREA OF MOISTURE
AND SNOW IS PUSHING INTO GRANT COUNTY...MEANWHILE A DEFORMATION BAND
EXTENDS FROM THE BLUE MOUNTAINS SOUTHWEST TO DESCHUTES COUNTY. AS A
RESULT WILL CONTINUE THE CURRENT ADVISORIES FOR THE JOHN DAY
BASIN...THE OCHOCO-JOHN DAY HIGHLANDS AND THE SOUTHERN OREGON BLUE
MOUNTAINS. WILL ALSO EXTEND THE ADVISORY FOR THE OREGON CASCADE EAST
SLOPES INTO THIS EVENING. ELSEWHERE SNOW HAS PUSHED INTO THE GRANDE
RONDE VALLEY AND WALLOWA COUNTY. AT THIS TIME EXPECT GENERALLY LIGHT
AMOUNTS OF SNOW IN THESE AREAS...3 INCHES OR LESS. WILL INCREASE
POPS TONIGHT ALONG THE BLUE MOUNTAIN FOOTHILLS DUE TO CONTINUED GOOD
LOW LEVEL UPSLOPE AND THE PROXIMITY OF THE DEFORMATION ZONE. PRECIP
SHOULD BE LIGHT IN THE FOOTHILLS WITH ONLY UP TO AN INCH SNOW
EXPECTED...HIGHEST AMOUNTS AT AREAS CLOSEST TO THE BLUE MOUNTAINS.
PRECIP WILL BECOME MORE SHOWERY IN NATURE OVERNIGHT AS WELL. A FEW
SNOW SHOWERS WILL LINGER OVER OUR EASTERN MOST ZONES ON SUNDAY.
OTHERWISE SHOULD SEE DRY AND FAIR CONDITIONS ELSEWHERE. ANOTHER
SYSTEM WILL MOVE SOUTH ALONG 130W SUNDAY NIGHT AND MONDAY. THIS
SYSTEM SHOULD HAVE LIMITED IMPACT ON THE INTERIOR NORTHWEST. SHOULD
SEE AN INCREASE IN CLOUDS AND A FEW SNOW SHOWERS NEAR THE CASCADE
CREST AND POSSIBLY IN THE WALLOWA MOUNTAINS FROM THIS SYSTEM.

BREEZY WINDS OVER PORTIONS OF THE AREA WILL DECREASE TONIGHT AS THE
LOW IN EXTREME SOUTHEAST OREGON MOVES EAST AND GRADIENTS WEAKEN. 90

.LONG TERM...MONDAY NIGHT THROUGH THURSDAY NIGHT...A LOW PRESSURE
SYSTEM WILL CONTINUE TO DROP SOUTH ALONG 130 WEST DURING THE START
OF THE WORK WEEK WHILE A TROUGH OF LOW PRESSURE SLOWLY SAGS SOUTH
INTO THE PACIFIC NORTHWEST. THIS TROUGH WILL BRING A CHANCE OF
SHOWERS TO THE REGION WITH THE HIGHER TERRAIN SEEING HIGHER CHANCES
TUESDAY AND WEDNESDAY. MODELS BEGIN TO DISAGREE WITH WHAT TO DO WITH
THE TROUGH ON THURSDAY. THE GFS MODEL DROPS THE CENTER OF THE TROUGH
ACROSS THE REGION BRING COLDER AIR...WHILE THE EUROPEAN ELONGATES
THE TROUGH ACROSS CANADA WITH A LOW PRESSURE CENTER CUTTING OFF OVER
VANCOUVER ISLAND. THE EUROPEAN MODEL WOULD KEEP THE COLDER AIR
FURTHER NORTH OF THE REGION. BOTH MODELS DO INDICATE A CHANCE OF
PRECIPITATION WITH HIGHER CHANCES IN THE MOUNTAINS...WITH THE
PRECIPITATION BEING MORE SHOWERY THAN STRATIFORM. SHOULD THE GFS
MODEL COME TO PASS...TEMPERATURES WILL BE WELL BELOW NORMAL WITH
SNOW POSSIBLE DOWN TO THE BASIN FLOOR BY WEDNESDAY. DMH

FRIDAY THROUGH SATURDAY NIGHT...THERE IS A BIT MORE DISCREPANCY IN
THE MODELS TODAY AS TO WHAT WILL HAPPEN IN THE EXTENDED. DGEX AND
GFS CONTINUE TO STAY CONSISTENT WITH VERY COLD AIR TO PUSH IN BY
FRIDAY...SUGGESTING SNOW TO ALL AREAS FOR THE WEEKEND.  HIGHS
TEMPERATURES WILL BARELY REACHING THE UPPER 20S IN THE WARMEST
SPOTS. GFS EVEN SUGGESTS SOME MORNING LOWS TO BE IN THE NEGATIVE 20
TO 30 RANGE FOR THE SOUTHERN MOUNTAIN AREAS AND BARELY ABOVE ZERO IN
THE WARMEST AREAS. ECMWF HAD FOLLOWED A SIMILAR TRACK UNTIL ITS LAST
COUPLE OF MODEL RUNS. CURRENT ECMWF INDICATES THE STRONG SURGE OF
COLD AIR TO BE PUSHED OFF TO THE EAST AS AN UPPER LEVEL TROUGH
DEVELOPS WELL OFF THE OR/WA/CA COAST. THIS ALLOWS FOR SOUTHERLY FLOW
TO TAKE PLACE OVER THE FORECAST AREA AND EVEN A WEAK RIDGE TO
POSSIBLY DEVELOP. WHILE THIS SCENARIO STILL FAVORS MOISTURE TO THE
AREA IT ALSO PROMOTES SIGNIFICANTLY WARMER TEMPERATURES. FRIDAY
AFTERNOON 850MB TEMPERATURES DIFFER BY 20 DEGREES CELSIUS OR 36
DEGREES FAHRENHEIT.  SO IT CAN BE SEEN WHY ONE MODEL IS EVEN
SUGGESTING HIGHS TO BE IN THE UPPER 30S TO LOWER 40S VS UPPER TEENS
TO LOWER 20S. RIGHT NOW HAVE TRENDED FORECAST TO THE MORE CONSISTENT
COLD AIR MODELS...GFS AND DGEX.  CURRENT FORECAST TEMPERATURES ARE
STILL WARMER THAN WHAT THESE MODELS SUGGEST DUE TO THE UNCERTAINTY
OF THE EXTENDED...BUT STILL SIGNIFICANTLY COLDER THAN THE ECMWF'S
CURRENT SOLUTION.  IF DGEX AND GFS MODELS WIN OUT WITH THE FORECAST
NEXT WEEKEND WILL LIKELY BE RECORD BREAKING IN MANY AREAS.  WE ARE
NOW GETTING INTO LATE FEBRUARY AND THIS KIND OF COLD AIR MASS IS
TYPICAL IN MID NOVEMBER TO LATE JANUARY. THEREFORE THESE EXTREME
TEMPERATURES WILL LIKELY SET SOME RECORDS. WEBER

&&

.AVIATION...00Z TAFS...A WEATHER SYSTEM THAT HAS BEEN ROTATING SNOW
INTO CENTRAL OREGON IS SHIFTING EAST AND IS SPREADING SNOW INTO THE
MOUNTAINS OF NORTHEAST OREGON THIS AFTERNOON. SNOW WILL CONTINUE IN
THESE LOCATIONS (IMPACTING KRDM) INTO THE EVENING HOURS BEFORE
DISSIPATING OVERNIGHT. IFR TO BRIEF PERIODS OF LIFR CEILINGS AND
VISIBILITIES WILL CONTINUE AT KRDM BEFORE IMPROVING TO MVFR
OVERNIGHT. ELSEWHERE...TAF SITES WILL BE MOSTLY VFR WITH MVFR IN
LOWER CEILINGS AT KPDT AND KALW DURING THE EVENING. CAN EXPECT VFR
CONDITIONS SUNDAY MORNING. WINDS WILL BE BREEZY AT KYKM AND KPSC
THROUGH THE EVENING BEFORE DECREASING OVERNIGHT AS THE SYSTEM MOVES
EAST. DMH
