PORTLAND (AP) — What may—or may not—be the last blast of summer heat is headed for Oregon.

Highs in most of the state will hit the 90s Monday and Tuesday with cooler evenings, with daytime highs going down by Wednesday in Western Oregon and by Thursday in the east.

Coastal highs are expected in the 60s and 70s with morning fog. A cooler weather pattern could bring spots of rain.
