Fire Weather Planning Forecast for NE Oregon and SE Washington
National Weather Service Pendleton OR
555 AM PDT Sat Sep 27 2025

.DISCUSSION...Quiet conditions will prevail over much of the
weekend, before the weather pattern turns wet starting Sunday
evening. A slow-moving weather system will make for persistent
chances for showers through much of the work week, with wetting
rains expected for most of the forecast area. Isolated
thunderstorms are possible across the high mountains Monday and
Tuesday afternoon, however the bulk of the rainfall is expected to
come in the form of showers. 


***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.
