* AFFECTED AREA...Fire Weather Zone 659 West Slopes of the Central Cascades Generally above 1500 Feet. * THUNDERSTORMS...Scattered thunderstorms with LAL 3 are expected during the afternoon and evening hours. * OUTFLOW WINDS...Gusty and erratic winds are possible in the vicinity of any thunderstorms that develop. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area.

Isolated to scattered thunderstorms containing little to no rainfall will be possible over much of Washington this afternoon and tonight. Any thunderstorms have the potential to produce gusty outflow winds that could travel quite a distance from the thunderstorm source. * Affected Area: Fire Weather Zone 707 Western Columbia Basin and Fire Weather Zone 708 Eastern Columbia Basin - Palouse -Spokane Area. * Thunderstorms: Isolated coverage for the western Columbia Basin and isolated to scattered as you head towards the Palouse and Spokane area. The best potential of thunderstorms for the Palouse and Spokane area looks to be after 5 PM. * Outflow Winds: Gusty and erratic winds are possible with any thunderstorms that develop. Gusty winds from thunderstorms that develop over the Cascades and north central Washington could send an outflow boundary across the Columbia Basin, Palouse and Spokane area. * Haines: High level haines of 6, which is high. This means very dry and unstable conditions exist. * Humidity: 12 to 19 percent. * Impacts: Unstable conditions could lead to plume dominated fires. Thunderstorms containing little to no rain and gusty winds combined with dry fuels will lead to the potential for new fire starts in addition to current fires, may overwhelm initial attack capabilities.
