AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PENDLETON OR 200 PM PDT MON JUL 3 2006 .SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT...SOUTH/SOUTHWEST FLOW ALOFT WILL CONTINUE THROUGH THE SHORT TERM...WITH PERIODIC WAVES ROTATING ACROSS THE PACIFIC NORTHWEST. ONE OF THESE WAVES IS APPROACHING IS MOVING ONSHORE THE NORTHERN CA/OREGON COAST...AND WILL MOVE N/NE ACROSS OREGON THIS EVENING...AND SOUTHERN WASHINGTON OVERNIGHT/EARLY TUESDAY. VISIBLE SATELLITE IS SHOWING CUMULUS BUILDUPS ACROSS MAINLY CENTRAL AND SOUTHERN OREGON...WITH ADDITIONAL DEVELOPMENT ALONG THE EAST SLOPES OF THE CASCADES. ISOLATED TO SCATTERED SHOWERS AND TSTMS WILL DEVELOP LATE THIS AFTERNOON ACROSS CENTRAL OREGON...MIGRATING NORTHWARD THIS EVENING AS FAR NORTH AS THE OREGON COLUMBIA BASIN. THIS WAVE IS NOT NEARLY AS POTENT AS THE ONE ON SUNDAY AFTN...THUS DO NOT EXPECT AS MANY TSTMS...WITH MOST STORMS WEAKER. WITH SOME INSTABILITY IN THE MIDDLE LEVELS OF THE ATMOSPHERE...THINK SOME STORMS WILL LINGER THROUGH THE NIGHT/EARLY TUESDAY...PARTICULARLY ACROSS SOUTH CENTRAL WASHINGTON/EXTREME NORTHERN OREGON AS THE WAVE CROSSES THE AREA. THE NEXT WAVE WILL APPROACH TUESDAY AFTN. SOME MODEL DIFFERENCES IN HANDLING THE WAVE...WITH THE NAM GENERATING A SIGNIFICANT COVERAGE OF SHWRS/TSTMS...WITH THE GFS KEEPING THE ENERGY WEST OF THE CASCADES...WITH LITTLE ACTIVITY. WITH SATELLITE TRENDS SHOWING THE WAVE NOT MUCH FURTHER TO THE NORTH AND WEST OF PREVIOUS WAVES...THINK THE GFS POSITION MAY BE TOO FAR WEST. ALSO THINK THAT THE NAM MAY BE OVERDONE A BIT ON THE TSTMS...ALTHOUGH INSTABILITY IS STILL SUFFICIENT AND SHEAR INCREASES. WILL RETAIN SLIGHT CHC TO LOW END CHC WORDING FOR OREGON TUE AFTN...SPREADING NORTHWARD TUESDAY EVENING INTO WASHINGTON. MORE STABLE MARINE AIR WILL BEGIN TO SPILL OVER THE CASCADES TUESDAY AFTERNOON...WITH COOLER TEMPERATURES/BREEZY CONDITIONS ALONG THE EAST CASCADE SLOPES. FAR EASTERN OREGON WILL SEE TEMPERATURES WARMER THAN MONDAY AFTERNOON CLOSEST TO THE SURFACE THERMAL TROUGH AXIS.

SO...RATHER THAN HAVING COOLER TEMPERATURES...HAVE BROUGHT SLIGHT WARMING TREND FOR SATURDAY AND SUNDAY.
