FIRE WEATHER PLANNING FORECAST FOR NE OREGON AND SE WASHINGTON
NATIONAL WEATHER SERVICE PENDLETON OR
645 AM PDT MON JUN 30 2025
DISCUSSION
HOT TEMPERATURES WITH LOW RHS WILL PREVAIL ACROSS
MUCH OF THE FORECAST AREA TODAY AND TOMORROW. WINDS WILL BE
LIGHTLY BREEZY THROUGH THE CASCADE GAPS EACH DAY, BEFORE PICKING
UP WEDNESDAY ONWARD, SPREADING INTO THE BASIN AS WELL. ISOLATED
THUNDERSTORMS ALSO BECOME A CONCERN OVER THE COURSE OF THE WEEK,
IMPACTING MAINLY CENTRAL OREGON AND THE EASTERN MOUNTAINS OF
OREGON. BOTH HOT AND DRY CONDITIONS, AS WELL AS THE DRY
THUNDERSTORM THREAT, WILL POSE A RISK FOR CRITICAL CONDITIONS AT
TIMES ACROSS THE FORECAST AREA.
***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.
