AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
350 AM PST THU DEC 27 2007

UPDATED AVIATION DISCUSSION

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT.  A BIG PACIFIC STORM IS
MOVING ONSHORE AND WILL BE A MAJOR SNOW PRODUCER OVER MOST OF OUR
FORECAST AREA OVER THE NEXT 24-36 HOURS.  SNOW WILL DEVELOP THIS
MORNING ALONG THE EAST SLOPES OF THE CASCADES AND WILL INCREASE IN
INTENSITY BY EARLY AFTERNOON.  THE EASTERN COLUMBIA RIVER
GORGE...THE KITTITAS AND YAKIMA VALLEYS...AND CENTRAL AND NORTH
CENTRAL OREGON  WILL ALSO SEE SNOW DEVELOPING AROUND NOON TODAY AND
INCREASING IN INTENSITY IN THE LATE AFTERNOON AND EVENING. BY EARLY
FRIDAY MORNING...THE FLOW WILL SWITCH TO THE WEST AND THE BOUNDARY
LAYER WINDS WILL SHIFT TO THE SW.  THEREFORE...PRECIPITATION IN THE
VALLEYS AND ACROSS CENTRAL OREGON WILL TAPER OFF ON FRIDAY. THE ONLY
EXCEPTION WILL BE AREAS JUST NEAR THE CASCADES WHERE SNOW WILL SPILL
OVER AND CONTINUE TO BRING PERIODS OF HEAVY SNOW THROUGH FRIDAY
AFTERNOON. WILL CUT THE SNOW ADVISORY FOR THE YAKIMA/KITTITAS VALLEY
AND THE EASTERN COLUMBIA RIVER GORGE TO 4 AM FRIDAY RATHER THAN 10
AM.

THE TIMING OF THE SYSTEM IS A LITTLE SLOWER THAN PREVIOUSLY
FORECAST...SO THE EASTERN MOUNTAINS WILL NOT SEE SNOW INCREASING
UNTIL THIS EVENING.  CONFIDENT THAT HEAVY SNOW WILL DEVELOP OVER THE
NORTHERN BLUES AND THE GRANDE RONDE VALLEY OVERNIGHT AND ON FRIDAY.
I WILL BE ISSUING HEAVY SNOW WARNINGS FOR THE BLUES AND A BLIZZARD
WARNING IN THE GRANDE RONDE VALLEY.  THE EASTERN MOUNTAINS AND
VALLEYS WILL SEE AREAS OF BLOWING SNOW...BUT WHITE OUT CONDITIONS
WILL CAUSE MAJOR PROBLEMS NEAR LADD AND PYLES CANYONS TONIGHT.

FOR THE SOUTHERN BLUES AND THE JOHN DAY BASIN AND OCHOCO
HIGHLANDS...BELIEVE SNOW AMOUNTS TONIGHT WILL REACH ADVISORY
CRITERIA BUT NOT HEAVY SNOW WARNING CRITERIA.

AS FAR AS THE BASIN AND BLUE MOUNTAIN FOOTHILLS...THERE MAY BE  SNOW
ACCUMULATIONS UP TO 2 INCHES IN AREAS WEST OF THE TRI-CITIES AND
HANFORD.  OTHERWISE...SOUTHERLY WINDS WILL PROVIDE ENOUGH
DOWNSLOPING ALONG THE FOOTHILLS TO WARM TEMPERATURES INTO THE 40S.
THE ONLY EXCEPTION WILL BE NEAR CONDON AND FOSSIL THAT MAY SEE LIGHT
ACCUMULATIONS OVER THE NEXT 24 HOURS.  JOHNSON

.LONG TERM...SATURDAY THROUGH WEDNESDAY...ACTIVE WEATHER PATTERN
WILL CONTINUE THROUGH THE WEEKEND. JETSTREAM WILL REMAIN OVER
EASTERN WASHINGTON OR OREGON WITH FREQUENT JET MAXES TRIGGERING
PRECIPITATION IN WEST TO NORTHWEST FLOW. THIS MAY LIMIT
PRECIPITATION IN NORMALLY RAIN SHADOWED AREAS IN COLUMBIA BASIN.
THERE WILL BE A FEW LINGERING SHOWERS IN THE NORTHEAST OREGON
MOUNTAINS MONDAY AS A A RIDGE BUILDS OFFSHORE. MONDAY NIGHT THROUGH
WEDNESDAY THE RIDGE WILL MOVE OVER THE PACIFIC NORTHWEST GIVING US A
TEMPORARY BREAK FROM THE FREQUENT STORMS PASSING THROUGH THE
REGION.  COONFIELD

&&

.AVIATION...VFR CONDITIONS WILL PERSIST UNTIL 18-20Z ACROSS ALL TAF
SITES. CEILINGS WILL LOWER TO 05-10 KFT ACROSS THE AREA AS NEXT
STORM DEVELOPS IN THE AFTERNOON. MVFR CEILING AND VISIBILITY IS
POSSIBLE AS EARLY AS 18Z AT DLS...WITH MVFR CEILINGS AND VISIBILITY
PREVALENT AT YKM AND RDM AS WELL BY 22Z. MVFR AND OCCASIONAL IFR
CONDITIONS WILL CONTINUE INTO THE NIGHT AS THE NEXT SYSTEM MOVES
THROUGH. LOWER CEILINGS AND VISIBILITY WILL BE DELAYED BY

DEVELOPMENT BETWEEN 06-08Z.  76
