In most non-mountain zones, breezy winds will overlap with near-critical or critically low relative humidity through this evening. Red Flag Warnings are in effect for wind/RH and abundant lightning with gusty outflow winds. Breezy winds will continue into Sunday, but RHs are anticipated to remain above critical thresholds. Above-normal temperatures and lower RHs are expected to return for Monday. ***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. *** WAZ695-231415- East Washington South Central Cascade Mountains- 210 PM PDT Sat Aug 22 2026 .TONIGHT... * Sky/weather.........Partly cloudy.
