AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
1030 AM PDT SAT SEP 8 2012

UPDATED AVIATION

.UPDATE...FIRST VISIBLE SATELLITE PICTURE OF THE DAY SHOW A COUPLE
OF AREAS OF CLOUDS ACROSS OREGON.  ONE AREA WILL BE MOVING FROM THE
NORTH SECTIONS IN WASHINGTON TODAY...AS ANOTHER AREA MOVES NORTH
FROM SOUTHWEST OREGON. THE WARM AND QUIET WEATHER CONDITIONS WILL
CONTINUE OVER THE REGION TODAY...BUT THE WATER VAPOR SATELLITE
PICTURES SHOW MOISTURE POISED TO SPREAD INTO CENTRAL OREGON LATE
TODAY.  THE MOISTURE WILL THEN WORK ITS WAY ACROSS MUCH OF CENTRAL
OREGON AND SOUTH CENTRAL WASHINGTON THIS EVENING AND ACROSS THE REST
OF THE FORECAST AREA OVERNIGHT.  THERE IS SOME INSTABILITY ALOFT AND
AS THE JET INTERACTS WITH THIS REGION...A SLIGHT CHANCE OF
THUNDERSTORMS IS POSSIBLE.  HAVE ADJUSTED THUNDERSTORMS AREAS A BIT
FOR COVERAGE AND UPDATED SKY CONDITIONS FOR LATER TODAY AND
OVERNIGHT.  93

&&
.AVIATION...18Z TAFS...VFR CONDITIONS TO PREVAIL WITH SCT-BKN ABV
120. WINDS WILL INCREASE AND BECOME GUSTY AT KDLS AFTER 06Z WITH THE
PASSAGE OF A WEAK COLD FRONT.

&&

.FIRE WEATHER...HIGH PRESSURE WILL KEEP THE AREA WARM AND DRY TODAY.
LATER THIS EVENING A LOW PRESSURE SYSTEM APPROACHING THE REGION WILL
BRING ENOUGH MOISTURE INTO THE AREA FOR ISOLATED SHOWERS AND
THUNDERSTORMS FROM THE CASCADES EASTWARD INTO THE BLUE MOUNTAINS AND
WALLOWA COUNTY BY SUNDAY MORNING. THESE WILL BE HIGH-BASED STORMS
WITH VERY LITTLE RAIN...BUT SHOULD ONLY BE LAL 2. THE CONVECTIVE
ACTIVITY WILL MOVE OUT OF THE AREA SUNDAY AFTERNOON. A COLD FRONT
WILL THEN COME IN FROM THE WEST WITH STRONG WINDS THAT WILL LAST
THROUGH SUNDAY EVENING...AND RETURN AGAIN ON MONDAY. THE COMBINATION
OF STRONG WINDS...LOW RELATIVE HUMIDITY AND CRITICALLY DRY FUELS
COULD CREATE EXTREME FIRE BEHAVIOR AND GROWTH BOTH SUNDAY AND
MONDAY...AND FIRE WEATHER WATCHES ARE IN EFFECT.  TRIMARCO

&&

.PREV DISCUSSION... /ISSUED 409 AM PDT SAT SEP 8 2012/

SHORT TERM...TODAY THROUGH SUNDAY NIGHT. HIGH PRESSURE THAT
DOMINATED OUR AREAS WEATHER WILL SLOWLY SLIP TO THE EAST TODAY. LOW
PRESSURE OVER THE E PAC WILL COMBINE WITH MOISTURE TO PRODUCE A FEW
LATE AFTERNOON AND EVENING THUNDERSTORMS OVER CENTRAL OREGON.

AN UPPER LEVEL JET WILL MOVE OVER OUR AREA TONIGHT. THIS WILL HELP
TO KEEP CONVECTION IN THE FORECAST AND THE THUNDERSTORMS SHOULD MOVE
EAST AND SPREAD INTO THE FOOTHILLS OF THE BLUE MOUNTAINS SUNDAY
MORNING. THE THUNDERSTORMS SHOULD MIGRATE INTO THE BLUE/WALLOWA
MOUNTAINS BY SUNDAY AFTERNOON.

A COLD FRONT IS FORECAST TO TRACK ACROSS OUR AREA SUNDAY AFTERNOON.
ALONG WITH BREEZY WEST WINDS...AFTERNOON HIGH TEMPERATURES SHOULD BE
NEARLY TEN DEGREES COOLER THAN THE PREVIOUS DAY.

AS THE LOW PRESSURE AND COLD FRONT MOVES AWAY FROM OUR AREA SUNDAY
NIGHT...ANOTHER STORM SYSTEM IS EXPECTED TO APPROACH THE WA/OR
CASCADES WITH A FEW SHOWERS POSSIBLE OVERNIGHT.

LONG TERM...MONDAY THROUGH FRIDAY...A DRY COLD FRONT WILL MOVE
THROUGH EASTERN WASHINGTON AND OREGON MONDAY. THIS WILL PRODUCE MUCH
COOLER TEMPERATURES AND WINDY CONDITIONS AS COOLER AIR ALOFT FILTERS
INTO THE AREA AND HIGHER WINDS ALOFT MIX TO THE SURFACE. BLOWING
DUST MAY BE A PROBLEM ACROSS THE LOWER COLUMBIA BASIN AND ADJACENT
VALLEYS.  TUESDAY THROUGH FRIDAY AN UPPER LEVEL RIDGE WILL BUILD
OVER THE AREA...ALLOWING FOR WARMER AIR AND MOSTLY SUNNY SKIES TO
RETURN. TEMPERATURES WILL RISE A FEW DEGREES EACH DAY DUE TO
SUBSIDENCE FROM THE RIDGE AND AIR MASS MODIFICATION DUE TO SUNNY
SKIES.  COONFIELD

&

AVIATION...12Z TAFS...VFR CONDITIONS WILL PREVAIL THROUGH THE NEXT
24 HOURS. THERE MAY BE SOME HIGH BASED CUMULUS DURING THE AFTERNOON
BUT PRECIPITATION IS NOT EXPECTED. WINDS WILL BE LIGHT THROUGH MOST
OF THE DAY ON SATURDAY AND THEN THEY WILL INCREASE FROM THE WEST TO
NORTHWEST AFFECTING TAF KDLS...KRDM AND KBDN THIS EVENING. WIND
SPEEDS WILL GENERALLY BE 10 KTS OR LESS ON TODAY AND THEN WILL
INCREASE TO 10 TO 20 KTS AT KRDM...KBDN AND KDLS DURING THE EVENING.
