832 FNUS56 KPDT 051355 FWFPDT Fire Weather Planning Forecast for NE Oregon and SE Washington National Weather Service Pendleton OR 655 AM PDT Fri Jun 5 2026 .DISCUSSION... Dry and Breezy conditions will overlap This Afternoon across the Eastern Columbia Gorge and Oregon Columbia Basin where combined probability for RH and wind speeds of 20% or less and 15 mph respectively area around 40 to 60%. Fuels are not quite cured enough for red flag concerns in these zones, yet. Farther north over the Washington Columbia Basin where fuels have cured more, combined probabilities on Friday for these rh and winds are around 5-25%. ***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 transport wind multiplied by the mixing height in 100's of ft. 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. Categories: low (< 200), moderate (200-500), high (500-700), and very high (> 700). -Note: Max transport winds may not occur at the same time as max mixing height. *** WAZ695-052315- East Washington South Central Cascade Mountains- 655 AM PDT Fri Jun 5 2026 .TODAY... * Sky/weather.........Partly cloudy.
