AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
215 PM PST SUN JAN 22 2012

.SHORT TERM...TONIGHT THROUGH WEDNESDAY...CURRENT WEATHER SYSTEM
WORKING ITS WAY THROUGH THE REGION WILL CONTINUE TO BRING LIGHT SNOW
TO THE EAST SLOPES OF THE WASHINGTON CASCADES INTO THE EVENING THEN
BEGIN TO DECREASE OVERNIGHT. WINTER WEATHER ADVISORIES CONTINUE IN
EFFECT UNTIL 4 AM MONDAY FOR THIS AREA. REST OF THE FORECAST AREA IS
SEEING SOME LIGHT PRECIPITATION BUT NOT AS WELL ORGANIZED SO LOOKING
AT MUCH LIGHTER ACCUMULATIONS EXPECTED. THIS SYSTEM WILL BE EXITING
OVERNIGHT AND EARLY MONDAY LEAVING A DRY AIRMASS OVER THE REGION
THROUGH MONDAY NIGHT. NEXT WEATHER SYSTEM WILL ARRIVE TUESDAY
BRINGING ANOTHER ROUND OF MOISTURE TO THE FORECAST AREA THROUGH
WEDNESDAY. THIS SYSTEM WILL HAVE MORE OF A SUBTROPICAL FETCH
ASSOCIATED WITH IT SO COULD BE LOOKING AT ANOTHER PROLONGED
PRECIPITATION EVENT MAINLY ALONG THE CASCADE REGION. THE SYSTEM WILL
BRING WARMER AIR WHICH WILL ALSO RAISE SNOW LEVELS AND BRING WARMER
TEMPERATURES. LOOKS LIKE THERE MIGHT BE AN INITIAL COLD POOL TRAPPED
ALONG THE EAST SLOPES OF THE WASHINGTON CASCADES ON TUESDAY WHICH
WOULD MEAN A POSSIBLE MIXED PRECIPITATION EVENT FOR THE YAKIMA AND
ELLENSBURG AREAS.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY NIGHT...MODERATE TO
HEAVY RAIN SHOWERS WILL CONTINUE FOR THE MAJORITY OF THE FORECAST
AREA WEDNESDAY NIGHT INTO THURSDAY.  BY THURSDAY NIGHT IT LOOKS AS
IF AN UPPER LEVEL RIDGE WILL TRY TO BUILD OVER THE AREA AND GIVE A
BREAK TO THE PRECIPITATION.  DEPENDING ON WHEN THE CLEARING OCCURS
THERE MAY BE ENOUGH TIME FOR PATCHY FOG TO DEVELOP...MAINLY ALONG
THE COLUMBIA RIVER GORGE THURSDAY NIGHT INTO FRIDAY MORNING. COOLER
NORTHWEST FLOW WILL SET IN FRIDAY LOWERING THE HIGH TEMPERATURES
INTO THE FORTIES FOR THE LOWER ELEVATIONS AND THE UPPER 20S TO 30S
MOUNTAINS. PATCHY FOG MAY DEVELOP AGAIN OVERNIGHT FRIDAY
NIGHT...WITH CLOUD COVER INCREASING DURING THE DAY FRIDAY. HAVE CUT
BACK POPS IN THE EXTENDED SIGNIFICANTLY AS IT SEEMS TO BE FAVORING
THIS DRY PATTERN.  GOING WITH SLIGHT CHANCE SNOW SHOWERS ALONG THE
MOUNTAINS OF NORTHEAST OREGON FRIDAY AND DRY ELSEWHERE. MODELS
FORECASTS DIVERGE A BIT ON SATURDAY.  GFS HAS BEEN HOLDING ONTO THE
RIDGE FOR SEVERAL MODEL RUNS NOW WITH A WEAK EMBEDDED
DISTURBANCE...WHEREAS THE ECMWF MODEL CONTINUES TO BRING IN AN UPPER
LEVEL TROUGH TO THE AREA WITH MUCH MORE PRECIPITATION ASSOCIATED.
DGEX HAS BEEN LEANING MORE TOWARDS THE GFS...AND FOR THIS WILL
CONTINUE TO GO WITH LOWER POPS FOR THE WEEKEND. TEMPERATURES WILL
STILL BE COOL AND IN THE MID 40S FOR THE WEEKEND AS NORTHWEST FLOW
DOMINATES THE FORECAST AREA. WEBER

&&

.AVIATION...00Z TAFS...THE NEXT ROUND OF MOISTURE CONTINUES TO MOVE
ACROSS THE AREA. EXPECT CIGS TO LOWER WITH RAIN/SNOW SHOWERS MOVING
IN. AS THE SYSTEM DEPARTS THE AREA TONIGHT...CLEARING SKIES AND
LIGHT WINDS WILL ALLOW FOR MIST AND POSSIBLY SOME FOG TO DEVELOP AT
MOST TAF SITES...SO ANTICIPATE MVFR/IFR CONDITIONS DURING THE EARLY
MONDAY MORNING HOURS. KALW AND KPDT MAY NOT BE AS PRONE TO LOWERED
VISIBILITIES DUE TO WINDS AROUND 6KTS OR SLIGHTLY GREATER. WINDS
WILL INCREASE THIS AFTERNOON AT KRDM, KBDN, KPDT AND KALW TO 10 TO
20 KTS WITH GUSTS TO 25 KTS AND CONTINUE THROUGH 03Z. OTHERWISE
WINDS WILL GENERALLY REMAIN BELOW 15 KTS. SHOWERS SHOULD TAPER OFF
BY TOMORROW AFTERNOON WITH VFR CONDITIONS PREVAILING FOR THE
REMAINDER OF THE DAY...AND LIGHT WINDS WILL BE ASSOCIATED. WEBER
