FIRE WEATHER PLANNING FORECAST FOR NE OREGON AND SE WASHINGTON
NATIONAL WEATHER SERVICE PENDLETON OR
259 PM PDT TUE JUN 17 2025
DISCUSSION
DRY AND LIGHTLY BREEZY CONDITIONS ARE EXPECTED THE
REST OF THE DAY TODAY, BEFORE A WEATHER SYSTEM ARRIVING TOMORROW
MAKES FOR ANOTHER ROUND OF GUSTY WINDS ACROSS THE FORECAST AREA.
ONLY LIGHT PRECIPITATION IS EXPECTED ACROSS THE WASHINGTON CASCADE
CRESTS. THURSDAY LOOKS TO BE QUIET, BEFORE ANOTHER, MORE POTENT
SYSTEM ARRIVES FRIDAY INTO SATURDAY. WHILE WINDS WILL BE GUSTY
ONCE AGAIN, MUCH COOLER TEMPERATURES AND WIDESPREAD SHOWER
CHANCES ARE EXPECTED TO MOVE INTO THE PACIFIC NORTHWEST, ALLOWING
FOR RHS TO REBOUND AFTER A WEEK OF DRY CONDITIONS.
***THUNDERSTORMS IMPLY STRONG GUSTY WINDS***
***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.
