NORTHEAST OREGON/SOUTHEAST WASHINGTON FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
245 AM PST SAT DEC 1 2001
AN UPPER LOW OFF THE COAST WILL CONTINUE TO SUPPLY WARM AIR
ADVECTION OVER THE FORECAST AREA THROUGH MUCH OF THE DAY. THIS WARM
AIR ADVECTION WILL AID IN PRODUCING LIGHT PRECIPITATION OVER MUCH OF
THE FORECAST AREA THIS MORNING. THE PRECIPITATION WILL DECREASE
THIS AFTERNOON OVER OUR WESTERN FORECAST AREA AND OVER THE REMAINDER
OF THE AREA TONIGHT AS THE SYSTEM EXITS OUR REGION. STRONG WINDS
AHEAD OF THIS SYSTEM WILL PRODUCE WINDY CONDITIONS OVER MOST OF THE
AREA TODAY. IN FACT...GUSTS MAY REACH 60 MPH OVER THE
BLUES...GRANDE RONDE VALLEY AND WALLOW COUNTY BY LATE MORNING AS 700
MB WINDS INCREASE TO 75 MPH. AS A RESULT...HAVE UPGRADED THE HIGH
WIND WATCH TO A WARNING OVER PORTIONS OF NORTHEAST OREGON. THE
WINDS SHOULD SLOWLY SUBSIDE TONIGHT AS THE SURFACE LOW PRESSURE
MOVES INTO SOUTHERN BRITISH COLUMBIA. MODELS ARE HAVING A DIFFICULT
TIME WITH THE TRACK OF THE NEXT SYSTEM WHICH SHOULD BEGIN AFFECTING
OUR WESTERN AREAS SUNDAY MORNING. WILL LEAN TOWARDS THE AVN
SOLUTION AS IT HAS BEEN THE BETTER MODEL LATELY. THEREFORE... WILL
GO WITH AN INCREASING THREAT OF PRECIPITATION BEGINNING SUNDAY
MORNING OVER OUR WESTERN ZONES. THE PRECIPITATION WILL SPREAD TO
OUR EASTERN ZONES BY LATE AFTERNOON SUNDAY. AT THIS TIME...BELIEVE
MUCH OF THE ACCUMULATING PRECIPITATION WILL HOLD OFF UNTIL SUNDAY
NIGHT. ANOTHER QUESTION TO PONDER IS HOW MUCH COLD AIR WILL FILTER
DOWN FROM CANADA. THE SYSTEM TODAY WILL LIKELY SCOUR OUT ALL
REMAINING COLD AIR OVER THE BASIN SO PRECIPITATION WILL START OUT AS
RAIN...BUT SHOULD TURN TO SNOW SUNDAY NIGHT AS 1000-850 MB
THICKNESSES FALL BELOW 1310. PRESENTLY...APPEARS RAIN WILL TURN TO
SNOW TOO LATE FOR ANY APPRECIABLE ACCUMULATION OVER THE BASIN AND
FOOTHILLS. EARLE
EXTENDED...THE UNSETTLED WEATHER WILL CONTINUE THROUGH NEXT
WEEK AS THE PATTERN REMAINS PROGRESSIVE. COOLER TEMPERATURES WILL BE
OVER THE AREA TUESDAY AND WEDNESDAY AS THE JET PLUNGES SOUTH OFF THE
COAST AND COLDER AIR ALOFT MOVES OVER THE AREA. RIDGING BETWEEN
SYSTEMS ON WEDNESDAY MAY PRODUCE ONE DRY DAY...PARTICULARLY DURING
THE DAY. THERE MAY BE PRECIPITATION TUESDAY NIGHT AND WEDNESDAY
NIGHT...BUT MY CONFIDENCE IS TOO LOW TO CHANGE IT YET. WILL LET DAY
SHIFT EVALUATE TIMING MORE CLOSELY. THEN A WARMING TREND WILL OCCUR
LATER IN THE WEEK AS THE COLDER AIR MOVES FARTHER NORTH AND
THICKNESS VALUES INCREASE. COONFIELD

1 high wind. Local standard time, as filed.
Sustained winds of over 40 mph were measured for several hours north of Ladd Canyon by an automated wind sensor. Blowing snow during this time lowered visibilities, leading to the closure of Interstate 84 through Ladd Canyon for several hours.
