PORTLAND, Ore. (KOIN) -- After a mostly sunny Sunday, expect temperatures to increase Monday across the Portland metro area. We should top out in the low-to-mid 80s for daytime highs in the Portland-Vancouver area, while the Oregon Coast will see temperatures mostly in the 60s.

Expect areas of brief morning clouds in the Willamette Valley with clearing along the coast by late morning to early afternoon. All in all, a very nice late summer day is on the way from the Oregon Coast to the Cascades.

The previously advertised warm up is still on the way for midweek.

An area of high pressure begins to build over the area from the desert southwest pushing temperatures into the low 90s across the metro area. Still no rain in sight in the next 7 to 10 days, as summer rolls on.
