672 FNUS56 KPDT 142126 FWFPDT Fire Weather Planning Forecast for NE Oregon and SE Washington National Weather Service Pendleton OR 226 PM PDT Thu Aug 14 2025 .DISCUSSION...Breezy conditions will back off this evening, before picking back up again during the day Friday, albeit with slightly lower wind gusts expected. A cool and wet trend is then expected to initiate starting late Friday night into Saturday as a cold front moves across the region. Confidence is moderate to high in this front bringing wetting rains to our mountain zones. Thunderstorms may develop over the weekend across the high mountains during the afternoon hours, however storms are generally expected to be wet and not strong to severe. ***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.
