AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
247 PM PDT SUN MAR 23 2008

.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT...A RELATIVELY STRONG
WEATHER SYSTEM CONTINUES TO PUSH INTO THE PACIFIC NORTHWEST THIS
AFTERNOON. THE SYSTEM/S COLD FRONT HAS MOVED ONSHORE AND MAKING IT/S
WAY TO THE WILLAMETTE VALLEY AND PUGET SOUND AT THE MOMENT. SPOTTY
LIGHT PRECIP HAS FALLEN AT A FEW LOCATIONS OTHERWISE THE REGION HAS
REMAINED LARGELY DRY SO FAR. MAY SEE A FEW SHOWERS AHEAD OF THE
FRONT...BUT EXPECT MAIN PRECIP TO OCCUR WITH THE FRONT AND IN THE
FAVORED UPSLOPE AREAS BEHIND THE FRONT TONIGHT. SNOW LEVELS WILL BE
HIGH INITIALLY AND THIS WILL LIMIT SNOW ACCUMULATIONS WITH BELOW
ADVISORY AMOUNTS ONLY EXPECTED ABOVE ABOUT 3500 FEET BY MONDAY
MORNING. WINDS HAVE BECOME BREEZY AHEAD OF THE FRONT IN CENTRAL
OREGON AND IN THE YAKIMA VALLEY. GRADIENTS AHEAD AND BEHIND THE
FRONT THIS EVENING LOOK TO BE TIGHTEST OVER SOUTH-CENTRAL WASHINGTON
WHILE WINDS ALOFT ARE CURRENTLY 30-40 KTS...AND THE JET WILL BE OVER
WASHINGTON AS WELL. THUS WILL ISSUE A WIND ADVISORY FOR THE YAKIMA
VALLEY AND THE LOWER COLUMBIA BASIN OF WASHINGTON FOR THIS EVENING.
ELSEWHERE BREEZY TO WINDY CONDITIONS CAN BE EXPECTED THIS
EVENING...AND A FEW LOCATIONS MAY BRIEFLY SEE STRONGER WINDS AT THE
TIME OF FRONTAL PASSAGE. AREA WILL BE UNDER A PERSISTENT WEST FLOW
FROM LATE TONIGHT THROUGH TUESDAY. THIS KEEP CONDITIONS COOLER THAN
SEASONAL. ISOLATED TO SCATTERED SHOWERS CAN BE EXPECTED...WITH THE
BEST CHANCES IN THE AFTERNOONS AND OVER/NEAR MOUNTAINS. CONDITIONS
MAY BE MOSTLY DRY IN THE DOWNSLOPE FAVORED AREA OF THE COLUMBIA
BASIN. A STRONGER DISTURBANCE LOOKS TO MOVE ACROSS THE REGION
TUESDAY NIGHT BRINGING BETTER CHANCES OF VALLEY RAIN AND MOUNTAIN
SNOW. 90

.LONG TERM...WEDNESDAY THROUGH SUNDAY...AN UNSETTLED PATTERN WILL
CONTINUE THROUGH THE EXTENDED PERIOD AS UPPER LEVEL LOW PRESSURE IN
THE GULF OF ALASKA WILL SEND A SERIES OF DISTURBANCES THROUGH THE
AREA IN A COOL WEST TO NORTHWESTERLY FLOW. THIS WILL GIVE THE AREA A
CHANCE OF RAIN AND SNOW WEDNESDAY AND WEDNESDAY NIGHT AS A TROUGH
MOVES THROUGH THE AREA. AFTER THAT WEAKER SHORTWAVES WILL GIVE THE
AREA A SLIGHT CHANCE OF PRECIPITATION IN THE LOWER ELEVATION WITH A
CHANCE IN THE MOUNTAINS. MAIN CHANGE TO THE FORECAST WAS TO DRY OUT
THE WESTERN PORTION OF THE COLUMBIA BASIN AS THE YAKIMA VALLEY AND
THE TRI-CITIES WILL TEND TO BE RAIN SHADOWED BY SYSTEMS IN A
WESTERLY FLOW. LATEST MODEL RUNS ARE HINTING AT OFFSHORE RIDGING BY
NEXT WEEKEND WHICH WOULD CUT OFF THE PRECIPITATION BY SUNDAY BUT
WILL WAIT FOR NOW BEFORE GOING WITH THAT SCENARIO. TEMPERATURES WILL
BE WELL BELOW NORMAL FOR MOST OF THE AREA THROUGH THE LONG TERM WITH
EVEN THE LOWEST ELEVATIONS HAVING A CHANCE OF SNOW SHOWERS DURING
THE OVERNIGHT HOURS. MOUNTAIN PASSES WILL LIKELY SEE SNOW BUT DO NOT
FORESEE AMOUNTS AT WARNING CRITERIA LEVELS. PERRY

PREVALENT FOR THE NEXT 24 HOURS. A WEATHER SYSTEM CROSSING THE AREA
TODAY WILL BEING A CHANCE OF SHOWERS THROUGH EARLY THIS EVENING.

DESCEND TO 4000-7000 FEET THIS AFTERNOON. DURING THIS TIME MVFR

THIS EVENING THE CEILINGS WILL BEGIN LIFTING AND PARTIAL CLEARING
WILL TAKE PLACE OVER THE COLUMBIA BASIN THROUGH TOMORROW MORNING.
