AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
215 PM PDT WED JUL 5 2006

.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT...CUMULUS DEVELOPMENT
TODAY ON A SLOWER PACE THAN YESTERDAY SO EXPECT THUNDERSTORMS TO BE
LATER IN THE DAY. SHOULD SEE SCATTERED ACTIVITY BY THIS EVENING. DEW
POINTS CONTINUE TO BE IN THE 40S AND 50S WITH SHORT WAVES MOVING
THROUGH IN SOUTHWESTERLY FLOW SO THUNDERSTORMS WILL HAVE DECENT
AMOUNTS OF RAIN. VISIBLE SATELLITE SHOWS STRATUS WEST OF THE
CASCADES WITH LITTLE OR NO INDICATION OF MARINE PUSH INTO EAST SIDE
ZONES YET. ONLY LOCATION WITH MODERATE WINDS WILL BE DLS. NOT MUCH
CHANGE TO THE PATTERN FOR THU WITH ANOTHER DAY OF THUNDERSTORMS
MAINLY SOUTHEASTERN PORTION OF FORECAST AREA. AIRMASS SHOULD BECOME
MORE STABLE BY FRIDAY WITH NO THUNDERSTORMS IN THE FORECAST. HIGH
TEMPS THU/FRI A LITTLE COOLER THAN RECENT DAYS. 94

.LONG TERM...SATURDAY THROUGH WEDNESDAY...MID RANGE MODELS HAVE
VERGED TOWARDS GENERAL AGREEMENT ON PATTERN FOR THE PERIOD SATURDAY
THROUGH MONDAY. MEANWHILE UNCERTAINTY REMAINS IN THE MODELS FOR
TUESDAY AND WEDNESDAY AS TO THE DEPTH OF AN UPPER LEVEL TROUGH
EXPECTED TO APPROACH THE NORTHWEST. OVERALL EXPECT UPPER LEVEL FLOW
TO BE WEST-SOUTHWEST TO WEST OVER THE PACNW...AT LEAST THROUGH
MONDAY. THIS SHOULD PRODUCE MOSTLY DRY CONDITIONS WITH TEMPS AT OR
SLIGHTLY ABOVE SEASONAL. THERE MAY BE ENOUGH INSTABILITY SATURDAY
AND SUNDAY FOR A STRAY AFTERNOON/EVENING THUNDERSTORM OVER THE
WALLOWA AND ELKHORN MOUNTAINS. BETTER CHANCES OF PRECIP ALONG THE
CASCADE CREST AND INTO CENTRAL OREGON ARE POSSIBLE IF THE A STRONG
TROUGH MOVES IN DURING THE MIDDLE OF THE WEEK. AT THIS TIME WILL
LIMIT TO A SLIGHT CHANCE OF SHOWERS OR THUNDERSTORMS OVER THE HIGHER
TERRAIN DUE TO THE UNCERTAINTY. 90

&&

.AVIATION...CEILINGS AND VISIBILITIES SHOULD REMAIN VFR THROUGH THE
NEXT 24 HOURS. ISOLATED THUNDERSTORMS ARE POSSIBLE OVER MUCH OF
THE REGION INTO THE EVENING. THESE STORMS COULD BRIEFLY LOWER
CIGS/VIS INTO THE MVFR RANGE DUE TO HEAVY RAIN. TIMING OF A
THUNDERSTORM AT A SPECIFIC TAF SITE WILL BE DIFFICULT AND WILL
CONTINUE TO INDICATE EITHER CUMULONIMBUS CLOUDS AND/OR VCTS AT
AFFECTED TAF SITES. THE MARINE PUSH WILL KEEP THE LOCAL AIR MASS
AROUND KDLS STABLE WHILE PRODUCING WEST WINDS OF AROUND 25 KTS
THROUGH 6/0600 UTC. EXPECT BREEZY WINDS AND INCREASINGLY STABLE AIR
TO MOVE OVER THE INTERIOR NORTHWEST THURSDAY...AND FOR NOW WILL NOT
MENTION CUMULONIMBUS CLOUDS OR VICINITY THUNDER THURSDAY. 90
