AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
145 PM PDT MON SEP 3 2007

.SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT...THE NEXT SYSTEM TO
AFFECT THE AREA IS CURRENTLY ALONG 130W. CLOUDS WILL INCREASE ACROSS
THE AREA TONIGHT AS THE SYSTEM APPROACHES THE REGION. HAVE FAVORED
THE FASTER GFS SOLUTION FOR THE TIMING OF THE TROUGH WITH THE SYSTEM
MOVING THROUGH TUESDAY MORNING AND THROUGH THE DAY. A CHANCE OF
SHOWERS AND THUNDERSTORMS WILL START OUT IN THE MORNING IN CENTRAL
OREGON AND THEN SPREAD EASTWARD THROUGH THE MORNING AND AFTERNOON.
BELIEVE THAT THE BEST CHANCES FOR THUNDERSTORMS WILL BE OVER THE
CENTRAL AND NORTHEAST OREGON MOUNTAINS. WINDS WILL BECOME BREEZY TO
WINDY ALONG AND BEHIND THE FRONT ASSOCIATED WITH THIS SYSTEM TUESDAY
AFTERNOON. THE SYSTEM WILL SLOWLY MOVE SOUTHEAST ACROSS THE
AREA...WITH DECREASING SHOWERS IN CENTRAL OREGON AND PORTIONS OF
NORTHERN OREGON AND WASHINGTON. WRAP AROUND MOISTURE FROM THE LOW
WILL KEEP A CHANCE OF SHOWERS GOING ACROSS THE MOUNTAINS OF
NORTHEAST OREGON TUESDAY NIGHT INTO WEDNESDAY. A DRY NORTHWEST FLOW
WILL MOVE OVER THE AREA WITH PRECIPITATION CHANCES DROPPING OFF
EVERYWHERE BY WEDNESDAY NIGHT.

TEMPERATURES TOMORROW WILL BE COOLER WITH AN INCREASE IN CLOUD
COVER...AND COOLER AIR WITH THE SYSTEM. LOWER ELEVATIONS WILL SEE
HIGHS IN THE LOWER TO MID 80S WITH 70S IN THE MOUNTAINS TUESDAY.
WEDNESDAY WILL SEE TEMPERATURES NEAR NORMAL ACROSS THE AREA. DK

.LONG TERM...THURSDAY THROUGH MONDAY.  THE EXTENDED PERIOD LOOKS DRY
WITH SLIGHTLY ABOVE NORMAL TEMPERATURES.  NORTHWEST FLOW WILL
PREVAIL THROUGH THURSDAY WITH A DRY COLD FRONT TO MOVE THROUGH
SATURDAY AS A TROUGH DIGS BACK OVER SOUTHWEST OREGON LATE SATURDAY
AND SUNDAY WITH NORTH FLOW AND THEN SHIFTING BACK NORTHWEST ON
MONDAY. ML

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL DURING THE NEXT 24 HOURS. AN
APPROACHING LOW PRESSURE SYSTEM WILL MOVE EAST OF THE CASCADES
DURING THE AFTERNOON ON TUESDAY. MID LEVEL CLOUDS WILL INCREASE
OVERNIGHT WITH SCATTERED SHOWERS SPREADING EAST OF THE CASCADES BY
12Z TUESDAY MORNING.

&&

.FIRE WEATHER...WINDS ARE INCREASING ALONG SOME OF THE EXPOSED
RIDGETOPS IN THE OCHOCO-JOHN DAY HIGHLANDS AND WALLOWA COUNTY.
AFTERNOON HUMIDITIES ARE IN THE TEENS.  CONDITIONS ARE JUST MEETING
RED FLAG CRITERIA.  BECAUSE THE BREEZY WINDS AND LOW HUMIDITIES ARE
ISOLATED...WILL HIGHLIGHT IN FORECAST RATHER THAN ISSUE A WARNING
FOR THIS AFTERNOON AND EVENING.

WILL UPGRADE THE FIRE WEATHER WATCH TO A RED FLAG WARNING FOR
TUESDAY AND TUESDAY EVENING FOR OUR CENTRAL AND EASTERN OREGON ZONES
BUT WILL CANCEL FOR THE NORTHERN BLUES OF WASHINGTON.  THE RED FLAG
WARNING IS FOR THUNDERSTORMS PRODUCING ABUNDANT LIGHTNING.  BELIEVE
MOST THUNDERSTORMS WILL PRODUCE WETTING RAIN (I.E. GREATER THAN A
TENTH OF AN INCH) AND POSSIBLY UP TO ONE HALF INCH...YET THE
CLOUD-TO-GROUND STRIKES WILL BE NUMEROUS AND WILL THREATEN THE
REGION WITH ADDITIONAL NEW FIRE STARTS.  WINDS WILL ALSO INCREASE
BEHIND THE LOW PRESSURE SYSTEM WITH BREEZY WINDS OVER PORTIONS OF
THE FORECAST AREA...ESPECIALLY IN THE COLUMBIA BASIN.  THE AFTERNOON
RELATIVE HUMIDITY WILL INCREASE INTO THE MID 20S TO MID 30S...SO NO
RED FLAG CONCERNS AS FAR AS WINDS.  SMITH
