FIRE WEATHER PLANNING FORECAST FOR NE OREGON AND SE WASHINGTON
NATIONAL WEATHER SERVICE PENDLETON OR
617 AM PDT FRI JUL 11 2025
DISCUSSION
HEAT WILL GRADUALLY BUILD THROUGH EARLY NEXT WEEK AS
HIGH PRESSURE MOVES IN OVER THE PACIFIC NORTHWEST. WINDS WILL BE
RELATIVELY LIGHT OUTSIDE OF THE KITTITAS VALLEY. THE REGION WILL
THEN BE CLIPPED BY AN UPPER-LEVEL SYSTEM ON TUESDAY, MAKING FOR A
MORE NORTHEASTERLY SHIFT IN THE WINDS THROUGH THE MIDDLE OF NEXT
WEEK. FORECAST CONFIDENCE DROPS OFF AFTER NEXT THURSDAY, BUT
WEATHER MODELS GENERALLY LEAN TOWARD A BENIGN PATTERN.
***WINDS ARE 20 FOOT 10 MINUTE AVERAGES***
***CWR-CHANCE OF WETTING RAIN 0.10 OR GREATER***
***VENTILATION INDEX IS DERIVED FROM THE
TRANSPORT WIND MULTIPLIED BY THE MIXING
HEIGHT IN 100'S OF FEET. INDEX CATEGORIES
ARE A GENERALIZED INDICATOR AND USERS ARE
ENCOURAGE TO DEVELOP CRITERIA THAT ARE
SUITABLE AND REPRESENTATIVE OF DISPERSION
CONDITIONS IN THEIR LOCAL AREA OF INTEREST.***
NOTE: MAX TRANSPORT WINDS MAY NOT OCCUR
AT THE SAME TIME AS MAX MIXING HEIGHT.
