AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
253 PM PDT MON AUG 21 2006...CORRECTED HEADLINE SECTION AT BOTTOM
.SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT. THE FORECAST AREA
WILL BE UNDER THE INFLUENCE OF TWO WEATHER SYSTEMS. ONE WAVE IS
CURRENTLY OVER NE OREGON AND BRINGING ISOLATED THUNDERSTORMS OVER
THE SOUTHERN BLUES AND WALLOWAS...ALTHOUGH LIGHTNING DETECTION HAS
ONLY SHOWED A FEW CLOUD-TO-GROUND STRIKES SO FAR THIS AFTERNOON. WE
HAVE RECEIVED REPORTS OF VIRGA AND GUSTY WINDS...AS STRONG AS 45
MPH...IN THIS AREA. A MUCH STRONGER SYSTEM IS MOVING INLAND ACROSS
SW OREGON. THIS SYSTEM WILL BRING ISOLATED-SCATTERED THUNDERSTORMS
ACROSS MOST OF THE FORECAST AREA TONIGHT. VISIBLE AND INFRARED
SATELLITE SHOW ENHANCED CLOUDS OVER CENTRAL OREGON WITH WEAK RETURNS
ON DOPPLER RADAR. THE CLOUD COVER OVER CENTRAL OREGON HAS INHIBITED
THUNDERSTORM DEVELOPMENT. HOWEVER...THERE WILL BE INCREASING
DYNAMICS WITH THE APPROACHING TROUGH. ANY BREAK IN THE CLOUDS WILL
PROVIDE SUFFICIENT SURFACE HEATING FOR THUNDERSTORMS LATE THIS
AFTERNOON AND EVENING. THE AIR MASS IS QUITE DRY IN THE LOWER
LEVELS...AND THUNDERSTORMS WILL BE DRY. THE TROUGH MOVING ACROSS
THE AREA WILL HELP TO MOISTEN THE ATMOSPHERE A LITTLE. IN
ADDITION...THE MARINE AIR WEST OF THE CASCADES WILL STEEPEN AND
SPREAD THROUGH THE EASTERN COLUMBIA GORGE. BY TUESDAY...SOME
THUNDERSTORMS WILL PRODUCE LIGHT RAIN WITH NO MORE THAN A TENTH OF
AN INCH EXPECTED. ONLY ISOLATED THUNDERSTORMS ARE FORECAST OVER THE
CENTRAL AND EASTERN MOUNTAINS AS THERE DOES NOT APPEAR TO BE ANY
ORGANIZED WAVE MOVING ACROSS OR/WA. THE NEXT LOW PRESSURE
SYSTEM...CURRENTLY CENTERED 40N/136W...WILL MOVE ACROSS OREGON
WEDNESDAY. THE GFS AND WRF HAVE DIFFERENT SOLUTIONS. THE GFS IS
SLOWER AND SOMEWHAT STRONGER. HOWEVER...BOTH MODELS SHOW LITTLE
MOISTURE AND INSTABILITY SO WILL NOT MENTION ANY PRECIPITATION. FROM
THE INITIAL DEVELOPMENT ON WATER VAPOR...THIS WAVE DOES RAISE AN
EYEBROW AND COULD BE STRONGER THAN MODELS INDICATE. WILL MONITOR
SATELLITE DATA BEFORE DISREGARDING MODEL SOLUTIONS. SMITH
.LONG TERM...THURSDAY THROUGH MONDAY...UNCERTAINTY IS HIGH DUE TO
WIDE VARIABILITY..MODEL TO MODEL AND RUN TO RUN. ON THURSDAY THE GFS
MODEL HAS A RIDGE BUILDING ON THE COAST WHILE THE ECMWF HAS A
CUTOFF LOW FORMING IN NORTHERN CALIFORNIA. LEFT FORECAST DRY SINCE
BOTH SOLUTIONS (BUILDING RIDGE AND SPLIT FLOW) ARE DRY IN EASTERN
WASHINGTON AND OREGON. WESTERLY FLOW WILL BE OVER THE PACIFIC
NORTHWEST FRIDAY THROUGH MONDAY WITH TIMING VERY INCONSISTENT AND NO
STRONG SYSTEMS MOVING THROUGH. WITH LOW CONFIDENCE DID NOT MAKE ANY
BIG CHANGES...JUST MOVED TEMPERATURES TOWARD ENSEMBLE MEAN AND KEPT
FORECAST DRY. COONFIELD
&&
.AVIATION...VFR CONDITIONS EXPECTED THE NEXT 24 HOURS. MID AND
HIGH LEVEL CLOUDS AT 12K-25K FEET MSL HAVE SPREAD OVER THE AREA.
ISOLATED THUNDERSTORMS ARE DEVELOPING OVER MOUNTAINS AND WILL SPREAD
OVER REST OF AREA BY EVENING. THESE STORMS MAY AFFECT TWB
366...368...AND 355 AND ALL TAF LOCATIONS. LOW LEVEL MOISTURE IS
LIMITED SO CEILINGS AND VISIBILITY WILL REMAIN VFR WITH LOCAL
CEILINGS 9K TO 12K FEET AGL IN THE VICINITY OF THUNDERSTORMS. WINDS
WILL BE BELOW 25 KTS EXCEPT AT KDLS AND VICINITY OF THUNDERSTORMS.
AREAS OF SMOKE AND HAZE FROM WILDFIRES WILL CONTINUE OVER MUCH OF
THE REGION. 76
&&
.FIRE WEATHER...DRY UNSTABLE AIRMASS TODAY WITH APPROACHING LOW
PRESSURE SYSTEM OFF THE OREGON COAST. HAVE SEEN A FEW LIGHTNING
STRIKES OVER EASTERN OREGON TODAY BUT EXPECT MORE LATE THIS EVENING
AS THE LOW MOVES INTO THE REGION. THUNDERSTORMS SHOULD DEVELOP OVER
CENTRAL OREGON LATE AFTERNOON AND EVENING THEN MOVE NORTH INTO
EASTERN WASHINGTON OVERNIGHT. LIMITED MOISTURE IN THE ATMOSPHERE
INITIALLY SO STORMS WILL BE DRY WITH VERY LITTLE RAINFALL. GUSTY
WINDS WILL BE A PROBLEM NEAR ANY STORM. RED FLAG WARNING FOR HAINES
6 CONDITIONS AND LOW HUMIDITIES WILL CONTINUE THROUGH 2000. RED FLAG
WARNING FOR LIGHTNING WILL CONTINUE THROUGH TONIGHT FOR MOST OF THE
AREA THEN FOR NORTHEAST OREGON AND SOUTHEAST WASHINGTON ON TUESDAY.
ANY STORMS ON TUESDAY SHOULD HAVE A LITTLE MORE RAINFALL ASSOCIATED
WITH THEM. OTHER CONCERN WILL BE THE MARINE PUSH ON TUESDAY. THIS
WILL BRING BREEZY TO WINDY CONDITIONS TO THE EAST SLOPES OF THE
CASCADES...COLUMBIA GORGE AND THE LOWER COLUMBIA BASIN. AT THIS POINT
IT LOOKS LIKE A MARGINAL WARNING EVENT. WILL EVALUATE ON TUESDAY
MORNING FOR ANY NEED TO ISSUE A WARNING.
