Weather forecast for Portland, OR for Tuesday, September 20


PORTLAND, Ore. (KOIN) — It can easily be in the 60s and 70s this time of year. Still, summer holds its own with temperatures in the mid-80s.

It’s beautiful weather for another planned summer hike. You may even have a few summer strawberries hanging in there. We’ll be trading all of that for our fall festivities in no time.

We embrace a late summer warming as an offshore wind keeps us dry and sunny on Tuesday. Expect above average temperatures the next day. We have wonderful weather for hiking and biking. You will have to move a bit faster as the day lengths are shorter now, but you will have comfortable temperatures for a long hike.

Expect your Tuesday to start in the 50s and then warm up to the mid 80s in the afternoon. Clouds are starting to roll in from the south, you will have moving clouds from southern Marion County on Tuesday afternoon.

A shaken atmosphere, due to an area of ​​low pressure in northern California, will return mid-week. It’s the same clip of energy that brought cooler temperatures and rain on Saturday. This area of ​​low pressure will usher in more cloud to the south and for parts of central Oregon today.
