AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
855 PM PST SAT JAN 28 2012

.UPDATE...THE LATEST IR SATL WAS SHOWING AN EXTENSIVE AMOUNT OF
CLOUDS OVER THE EASTERN HALF OF THE AREA. ALSO A WEAK DISTURBANCE
WAS MOVG INTO THE PACNW SPREADING MID AND HIGH LEVEL CLOUDS TO THE
WA/OR CASCADES. A RIDGE OF HIGH PRESSURE TO THE SOUTH WAS KEEPING
ANY PCPN AWAY FROM THE REGION TONIGHT BUT THIS RIDGE SHOULD SLIP FAR
ENOUGH SOUTH TOMORROW TO ALLOW A FEW SHOWERS TO INVADE THE REGION.
OTHERWISE SOME BREEZY SOUTH WINDS WERE AFFECTING THE GRANDE RONDE
VALLEY AND THIS IS COVERED IN THE ZONES. OVERNIGHT LOW TEMPERATURES
APPEAR IN THE BALLPARK AND THE PRESENT SHORT TERM FORECAST APPEARS
ON TRACK FOR NOW.

&&

.AVIATION...VFR CONDITIONS WILL PERSIST ACROSS ALL TAF SITES INTO
TOMORROW. HOWEVER A DISTURBANCE WILL LOWER CEILINGS AFTER 18Z AND
CREATE AREAS OF MVFR CONDITIONS ESPECIALLY IN SHOWERS MOSTLY ACROSS
TAF SITES KYKM...KPSC...KALW...KPDT...KDLS.

&&

.PREV DISCUSSION... /ISSUED 132 PM PST SAT JAN 28 2012/

SHORT TERM...TONIGHT THROUGH TUESDAY...RIDGE OF HIGH PRESSURE OVER
THE REGION WILL BEGIN TO BREAKDOWN OVERNIGHT ALLOWING THE FIRST OF
TWO WEATHER SYSTEMS INTO THE REGION ON SUNDAY. THE OTHER WILL FOLLOW
ON TUESDAY. SUNDAYS SYSTEM WILL BEGIN TO SPREAD SOME PRECIPITATION
OVER THE EAST SLOPES OF THE WASHINGTON CASCADES LATE TONIGHT AND
EARLY SUNDAY. SNOW LEVELS WILL BE HIGH BUT WITH POSSIBLE POCKETS OF
COLD AIR IN THE VALLEYS THERE IS THE THREAT OF SOME FREEZING RAIN
THROUGH SUNDAY MORNING MAINLY NORTH AND WEST OF YAKIMA. TEMPERATURES
ARE EXPECTED TO WARM BY MIDDAY TO ABOVE FREEZING SO VERY LITTLE ICE
ACCUMULATIONS ARE EXPECTED. REST OF THE FORECAST AREA WILL
EXPERIENCE RAIN WITH HIGH ELEVATION SNOW. NO SIGNIFICANT SNOW
ACCUMULATIONS EXPECTED BELOW ELEVATIONS USED FOR MASS TRANSIT.
PRECIPITATION WILL DECREASE LATE SUNDAY INTO EARLY MONDAY AS A BREAK
DEVELOPS BETWEEN THE WEATHER SYSTEMS. THE NEXT WEATHER SYSTEM WILL
MOVE INTO THE REGION ON TUESDAY BRINGING ANOTHER INCREASE IN
PRECIPITATION. ONCE AGAIN EXPECTING RAIN IN THE LOW ELEVATIONS AND
SNOW IN THE MOUNTAINS.

WILL NEED TO WATCH THE WINDS IN THE GRANDE RONDE VALLEY OVER THE
NEXT 24 TO 36 HOURS. THERE WILL BE SOME LOCALLY VERY WINDY
CONDITIONS IN THE SOUTHERN PORTION OF THE GRANDE RONDE VALLEY WHICH
COULD APPROACH ADVISORY CONDITIONS DURING THIS PERIOD.

LONG TERM...TUESDAY NIGHT THROUGH FRIDAY NIGHT...A WEATHER
DISTURBANCE WILL CONTINUE TO MOVE EAST AND OUT OF THE FORECAST AREA
TUESDAY NIGHT INTO WEDNESDAY. THIS WILL LEAD TO A GRADUAL DECREASE
IN PRECIPITATION IN THE LOWER ELEVATIONS AND RESIDUAL SHOWERS IN THE
MOUNTAINS THROUGH THE MIDDLE OF THE WEEK. ON THURSDAY...MODELS ARE
SHOWING A RIDGE OF HIGH PRESSURE MOVING INTO THE PACIFIC NORTHWEST
AND STRENGTHENING THROUGH THE END OF THE WEEK. THIS WILL LEAD TO A
DRYING TREND AND LIGHTER WINDS. SOME CLOUDS MAY MOVE OVER THE TOP OF
THE RIDGE LEADING TO PARTLY CLOUDY SKIES OVER THE REGION.
TEMPERATURES WILL GRADUALLY WARM EACH DAY...ESPECIALLY IN THE HIGHER
TERRAIN AND CENTRAL OREGON. THE POTENTIAL FOR THE DEVELOPMENT OF
INVERSIONS MAY KEEP THE LOWER ELEVATIONS (PARTICULARLY THE COLUMBIA
BASIN) FROM WARMING AS FAST AS THE SURROUNDING AREAS. WILL NEED TO
MONITOR THE SITUATION TO SEE IF FOG WILL NEED TO BE ADDED TO THE
FORECAST. WITH IT BEING INTO FEBRUARY...FOG DEVELOPMENT IS NOT AS
STRONG AS IT IS EARLIER IN THE WINTER SO AN INCREASED SOLAR ANGLE
LEADING TO FASTER FOG BURNOFF MAY LEAD TO A DECREASED THREAT IN
WIDESPREAD FOG. DMH
