AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
300 AM PST WED NOV 18 2015

.SHORT TERM...TODAY THROUGH FRIDAY...A STRONG COLD FRONT THAT HAS
MOVED ACROSS THE CWA LAST EVENING HAS MOVED EAST AND BROUGHT WITH IT
THE PRECIPITATION ASSOCIATED WITH IT. IN IT'S WAKE THERE ARE JUST A
FEW LIGHT SHOWERS OVER THE MOUNTAINS. EXPECT CONTINUED IMPROVEMENT
THROUGH TODAY. WINDS ARE ALSO DECREASING AS THE FRONT MOVES FARTHER
AWAY TO THE EAST. HOWEVER IT IS STILL BREEZY TO WINDY IN MANY
LOCATIONS...IF NOT MOST LOCATIONS. EXPECTED A GRADUAL DECREASE IN
WIND TODAY AS WELL...BUT IT WILL STILL BE BREEZY TO LOCALLY
WINDY...ESPECIALLY ON EXPOSED RIDGE TOPS AND OPEN AREAS SUCH AS THE
LOWER COLUMBIA BASIN AND ADJACENT VALLEYS. MOISTURE WITH THE NEXT
SYSTEM WILL MOVE INTO THE REGION TONIGHT AND THURSDAY OVER THE TOP
OF A FLAT RIDGE IN A FAST NORTHWEST FLOW ALOFT. THIS WILL BRING MORE
RAIN AND HIGHER MOUNTAIN SNOW TO THE FORECAST AREA FOR TONIGHT AND
THURSDAY. SNOW LEVELS WILL START OFF LOW ENOUGH FOR SOME SNOW IN THE
HIGHER MOUNTAINS...BUT WITH ONLY LIGHT ACCUMULATIONS BEFORE CHANGING
TO RAIN...ESPECIALLY SOUTHERN PORTIONS OF THE CWA. WILL SEE
IMPROVEMENT AGAIN ON FRIDAY AS THE MOISTURE PUSHES OFF TO THE EAST-
SOUTHEAST ON FRIDAY WITH A COOL NORTHWEST FLOW ALOFT IN IT'S WAKE.
TEMPERATURES TODAY WILL BE SLIGHTLY ABOVE NORMAL BUT THEN SLIGHTLY
BELOW NORMAL ON THURSDAY AND FRIDAY. THE YAKIMA RIVER WILL CONTINUED
HAVE MINOR FLOODING DUE TO HEAVY RAINFALL FROM THE LAST 24 TO 48
HOURS. WILL LET THE HIGH WIND WARNINGS AND WIND ADVISORIES EXPIRE AT
4 AM AS SCHEDULED AS WINDS CONTINUE TO DECREASE...EXCEPT FOR THE
NORTHERN BLUES...THE BLUE MOUNTAIN FOOTHILLS OF OREGON...CENTRAL AND
NORTH CENTRAL OREGON...AND WALLOWA COUNTY WHICH WILL BE EXTENDED
UNTIL 9 AM AS STRONG WINDS CONTINUE IN THOSE AREAS. 88

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...REGION WILL BE UNDER THE
INFLUENCE OF A MID/UPPER LEVEL RIDGE OF HIGH WITH ASSOCIATED SINKING
AIR MOTION PRODUCING DRY CONDITIONS THROUGH MONDAY. MONDAY NIGHT AND
TUESDAY MODELS INDICATE A DIGGING MID/UPPER LEVEL LONG WAVE TROUGH
OFFSHORE. HOWEVER, THE GFS SOLUTION IS MUCH MORE PROGRESSIVE BY
TAKING THE TROUGH INLAND ON MONDAY AND SPREADING A CHANCE OF
PRECIPITATION INTO FORECAST AREA BY DAYBREAK ON MONDAY, WHEREAS THE
ECMWF 00Z RUN INDICATES THAT THE TROUGH DIGS CONSIDERABLE MORE
SOUTHWARD AROUND 130-140W AND THUS REMAIN WELL OFFSHORE THROUGH
MONDAY AFTERNOON THUS PREVENTING PRECIPITATION ON THE EASTERN FLANK OF
THE TROUGH FROM REACHING THE COAST ON MONDAY RESULTING IN A DRY DAY
ACROSS FORECAST AREA. BOTH MODELS INDICATE PRECIPITATION OVER
FORECAST AREA MONDAY NIGHT. AS SUCH GIVEN POOR AGREEMENT
BETWEEN THE GFS AND ECMWF 00Z RUNS, MY CONFIDENCE IN THE POP FORECAST
FOR MONDAY IS NOT VERY HIGH AND I THEREFORE DECIDED TO KEEP A DRY
FORECAST FOR THE INTERIOR PACIFIC NORTHWEST REGION THROUGH MONDAY
AFTERNOON. MODELS COME INTO BETTER AGREEMENT OVERALL FOR MONDAY
NIGHT AND TUESDAY SINCE THEY BOTH SHOW THE MID/UPPER LONG WAVE
TROUGH CONTINUING OVER FORECAST AREA THROUGH TUESDAY AFTERNOON FOR
POPS BECOMING SLIGHT CHANCE MONDAY NIGHT AND THEN INCREASING POPS
TUESDAY. SNOW LEVELS ON TUESDAY WILL BE BETWEEN 3500 TO 4500 FEET.
