Northwest Heat Subsides, Dry Conditions Remain

After four consecutive days of 90-degree heat, some relief is on the way for Seattle and other areas of the Northwest.

The oppressive heat that dominated the end of July in the Northwest will be replaced with warm, but more seasonable temperatures this week. This heat relief arrives as an upper-level disturbance digging southeast, displacing the area of high pressure responsible for the heat. A more refreshing onshore flow will take hold by Tuesday.

AccuWeather.com Meteorologist Steve Travis explains, "A persistent dome of high pressure over the Northwest has brought scorching temperatures over the weekend. This feature will gradually shift to the east early in the week, allowing slightly cooler air to filter into the region."

The more seasonable weather will be inviting to those with outdoor plans such as hiking, biking and camping. AccuWeather RealFeel® readings made the conditions for outdoor activities oppressive in the final days of July.

Seattle, Washington will see 90-degree heat replaced with highs near 80 F by Wednesday. The average high temperature for this time of year is 77 F. Despite the cooler weather this week, rain is not in the forecast near Seattle where it is needed.

Portland, Oregon observed triple-digit heat to conclude the month of July. Residents and visitors here will experience temperatures on par with the normal high of 82 F by midweek. Dry conditions will preside over the week.

According to Steve Travis, "Rain chances will remain relatively low during most of the week, with just a few afternoon thunderstorms popping up over higher elevations."

Much of the Northwest remains under moderate-to-extreme drought, according to the United States Drought Monitor. Meanwhile, normal to above-average rain fall has lead to minimal drought conditions along the eastern front range of the Rocky Mountains.
