PORTLAND, Ore. (KOIN) — Warm and drier air is now starting to work its way back into the Portland region as August heat begins to build.

Morning clouds will help keep temperatures slightly below average Thursday as the latest round of summer heat continues to build. Afternoon sunshine will push temperatures into the low to mid-80s Thursday in the Rose City.

Skies will begin to clear Thursday as temperatures return to the low 80s during the afternoon and evening hours.

The cloud coverage and mild temperatures are thanks to Wednesday morning’s cold front that moved through the Pacific Northwest. Very little rain fell across the area as the dry stretch of weather begins to build again.

Building heat comes as high pressure develops over the Pacific Ocean this weekend

Now, a heat wave begins to build over the Pacific Ocean. That heat will build and move towards western Oregon and Washington this weekend and continue into next week. Afternoon and evening highs will likely sit about 10-15 degrees above normal as the number of dry days begins to grow again across the region.

These above average temperatures will continue through the middle of next week. Not only will the valley locations feel the heat, but the Oregon Coast will also see warmer conditions.
