Today, temperatures climbed into the mid-80s across much of Western Washington. Weather conditions looked great for Seattle’s World Cup match as clouds lifted around midday, allowing for increasing sunshine and temperatures that reached the low 80s by post game.

Tomorrow, temperatures will cool back into the mid-70s as an upper-level area of low pressure tracks across British Columbia. This system will increase onshore flow and bring a stronger westerly push through the region. Morning clouds will give way to afternoon sunshine, making for a pleasant start to the weekend.

The same weather system will also create elevated fire danger east of the Cascades. A Fire Weather Watch remains in effect on Saturday for portions of Eastern Washington where blustery winds and low relative humidity values could support rapid fire growth.

Seattle to feel the heat again on Sunday

By Sunday, temperatures will rebound into the low 80s around Seattle. The warming trend will accelerate early next week, with highs approaching 90 degrees Monday and reaching 91 degrees Tuesday. Tuesday will be a Weather Alert Day as residents should prepare for significant heat and elevated fire danger. Temperatures may challenge daily records in some locations.

Seattle weather stays comfortably warm through the weekend before Seattle experiences a major weather warmup early next week.

The hot pattern will continue Wednesday with highs remaining in the upper 80s before temperatures ease back into the upper 70s Thursday. No rainfall is expected through the upcoming week. While a few long-range models hint at the possibility of isolated light showers next weekend, confidence remains low. The overall trend favors slightly cooler temperatures by that time.

Seattle weather trends cooler Saturday before Seattle enters a significant weather warming trend Sunday through Wednesday.
