FNUS56 KPDT 081130 FWFPDT Fire Weather Planning Forecast for NE Oregon and SE Washington National Weather Service Pendleton OR 430 AM PDT Wed Jul 8 2026 .DISCUSSION...Elevated fire weather concerns through the week across WA690, WA691, and OR691 during the late afternoon and evening. This is related to low afternoon humidities of 15-25% and west-northwest winds of around 15 mph with gusts near 30 mph. These elevated concerns peak Thursday due to minimum humidities dropping into the mid-teens. Conditions alleviate slightly Friday and Saturday before lower winds next week. ***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. *** WAZ695-082315- East Washington South Central Cascade Mountains- 430 AM PDT Wed Jul 8 2026 .TODAY... * Sky/weather.........Partly cloudy then becoming mostly sunny. * Max temperature.....69-79...except 60-70 ridges. * Min humidity........34-49 percent. * 20-foot winds....... * Valleys/lwr slopes...Northwest winds 7 to 13 mph with gusts up to 25 mph. * Ridges/upr slopes....Northwest winds 7 to 13 mph. * CWR.................0 percent. * Chc of lightning....0 percent. * Mixing height.......7000 ft agl. * Transport winds.....Northwest around 15 mph. * Ventilation Index...Low to moderate (133-223) increasing to moderate to high (335-565) in the afternoon. .TONIGHT... * Sky/weather.........Partly cloudy. * Min temperature.....45-52. * Max humidity........64-79 percent. * Humidity recovery...Good. * 20-foot winds....... * Valleys/lwr slopes...West winds 7 to 13 mph with gusts up to 25 mph. * Ridges/upr slopes....West winds 7 to 13 mph. * CWR.................0 percent. * Chc of lightning....0 percent. * Mixing height.......500 ft agl. * Transport winds.....Northwest 15 to 20 mph. * Ventilation Index...Moderate (220-354) decreasing to low (55-99) after midnight. .THURSDAY... * Sky/weather.........Partly cloudy then becoming sunny. * Max temperature.....70-79...except 61-70 ridges. * Min humidity........28-43 percent. * 20-foot winds....... * Valleys/lwr slopes...Northwest winds 4 to 10 mph. * Ridges/upr slopes....West winds 5 to 11 mph. * CWR.................0 percent. * Chc of lightning....0 percent. * Mixing height.......8500 ft agl. * Transport winds.....West around 15 mph. * Ventilation Index...Low to moderate (122-218) increasing to moderate to high (441-667) in the afternoon. .Forecast days 3 through 7...... .FRIDAY...Mostly clear.
