Bottom Line: Above normal temperatures and relatively dry conditions are expected for the foreseeable future. This will lead to occasional periods of heat as well as increased fire danger.
Today through Sunday, August 21: Above normal temperatures are expected this week, with temperatures spiking on Wednesday and Thursday. Thursday will likely be the warmest day with temperatures reaching the upper 80s to mid 90s for most lowland locations away from the coast, bringing a moderate HeatRisk to much of the region. Dry and unstable conditions are also expected to peak Thursday, increasing the fire danger to near critical conditions, particularly for the Cascade zones. Fortunately, this heat event is expected to be relatively short-lived with temperatures decreasing by Friday (though still remaining above normal). We will be monitoring the potential for dry thunderstorms this weekend (mainly over the mountains) as well as another brief warm-up. See the latest briefing for additional details.
August 22 - 28: Above normal temperatures and relatively dry conditions are expected to last through late August.
August 27 - September 9: While the signal weakens late August into early September, there is still a signal for relatively warm and dry conditions.
