Fall-like feelings return to Portland area starting Tuesday

PORTLAND, Ore. (KOIN) -- Summer heat continues to fade around Portland as clouds increase and the chance of rain ramps up later this week.

A mix of sun and clouds will start the day off Tuesday as temperatures begin to cool. Below average highs will put the Willamette Valley into the mid to upper 70s. Increasing clouds will help slow the warming trend Tuesday as Oregon's next storm approaches.

Rain showers aren't expected to return until late Tuesday night and overnight.
