AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
256 AM PDT MON JUL 25 2011

.SHORT TERM...TODAY THROUGH WEDNESDAY MORNING...AN UPPER LOW NOW
APPROACHING THE PACIFIC NORTHWEST COAST WILL SWING ACROSS THE REGION
TODAY, EXITING BY MIDNIGHT. THIS SYSTEM HAS ALREADY KICKED OFF
ISOLATED LIGHT SHOWERS AND VERY ISOLATED THUNDERSTORMS OVER THE
NORTHERN TWO-THIRDS OF OUR AREA. AS THIS UPPER LOW MOVES ONSHORE IT
SHOULD KEEP THE POTENTIAL FOR ISOLATED SHOWERS AND THUNDERSTORMS
GOING THIS MORNING. THE UPPER LOW'S CENTER IS EXPECTED TO TRACK
ACROSS EASTERN WASHINGTON WHICH SHOULD INCREASE SHOWER COVERAGE TO
SCATTERED THIS AFTERNOON. ALSO MAY SEE SCATTERED COVERAGE OF
THUNDERSTORMS OVER THE BLUE MOUNTAINS AND PORTIONS OF WALLOWA COUNTY
LATE THIS AFTERNOON INTO EARLY THIS EVENING. INCREASING WEST FLOW
WILL GRADUALLY END THE THUNDERSTORM THREAT FROM WEST TO EAST. WINDS
WILL INCREASE AS THIS SYSTEM MOVES ACROSS THE AREA WITH BREEZY TO
LOCALLY WINDY CONDITIONS EXPECTED BY AFTERNOON. WINDS IN THE
KITTITAS VALLEY AND COLUMBIA RIVER GORGE ARE EXPECTED TO REACH THE
30 TO 38 MPH RANGE, THUS WILL ISSUE WIND ADVISORIES FOR THESE AREAS.
ONCE THE UPPER LOW EXITS INTO IDAHO AND MONTANA LATE THIS EVENING,
SHOULD SEE MOST PRECIP CHANCES END, THOUGH SOME SHOWERS MAY CONTINUE
TO SLOP OVER THE CASCADE CREST LATE TONIGHT THROUGH EARLY WEDNESDAY
MORNING. 90

.LONG TERM...WEDNESDAY THROUGH SUNDAY. MODELS HAVE CONSISTENTLY
SHOWN THE PACIFIC NW UNDER A WESTERLY FLOW ALOFT THROUGH THE
EXTENDED PERIOD. ANY DISTURBANCE EMBEDDED IN THE FLOW WILL MAINLY
BRING BREEZY WINDS...LOCALLY WINDY. CONFIDENCE IN A DRY FORECAST IS
HIGH ALTHOUGH THERE MAY BE SOME CUMULUS BUILDUPS OVER THE MOUNTAINS
WITH POSSIBLE SPRINKLES. NEXT WEEKEND LOOKS WARMER AS THE FLOW BACKS
TO THE SW IN RESPONSE TO A TROUGH DEVELOPING OFFSHORE. THE THREAT OF
THUNDERSTORMS IS MINIMAL AS MODELS...ESPECIALLY GFS...SHOW VERY
LITTLE MOISTURE. JOHNSON

&&

.AVIATION...PREVIOUS DISCUSSION...06Z TAFS...VFR CONDITIONS TO
PREVAIL THROUGH 06Z TUESDAY...EXPECT A SLOW INCREASE IN CLOUD COVER
DURING THE NEXT 12 HOURS AS SATELLITE INDICATES CLOUD COVER
APPROACHING FROM THE WEST AS WELL AS SOUTH. BY MONDAY MORNING AND
THROUGHOUT THE DAY EXPECT HIGH BASED CU AND MID CLOUD ABOVE WITH
ISOLATED TO SCATTERED THUNDERSTORMS AROUND ESPECIALLY N AND E. WILL
HANDLE THE STORMS WITH A CB GROUP. WINDS WILL BE ON THE INCREASE BY
LATE AFTERNOON WITH GUSTS AOA 25 KT POSSIBLE AT MOST OF THE SITES
THROUGH MID EVENING.

&&

.FIRE WEATHER...AN UPPER LOW IS NOW APPROACHING THE PACIFIC
NORTHWEST COAST AND HAS BEEN INSTIGATING SOME VERY LIGHT SHOWERS
OVER A GOOD PORTION OF THE AREA. ALSO IT HAS BE CAUSING THE
OCCASIONAL LIGHTNING STRIKE IN THE EASTERN END OF WA631 AND OR631.
THE UPPER LOW CONTAINS TO HAVE A RATHER IMPRESSIVE VORT MAX WHICH
SHOULD TRACK EAST-NORTHEASTWARD ACROSS SE WASHINGTON DURING THE DAY.
THIS SHOULD RESULT IN CONTINUED THUNDERSTORM ACTIVITY THROUGH TODAY.
MUCH OF THE ACTIVITY OVER WA675/WA631 AND OR631 SHOULD BE DONE BY
LATE AFTERNOON OVER THE WESTERN PORTIONS AND BY 8 PM IN THE FAR
EAST. ALSO WINDS ARE EXPECTED TO PICK UP TODAY, THUS ANY LIGHTNING
STARTS WILL HAVE THE POTENTIAL TO RUN WITH THIS WIND. 90
