What do you want to know

PORTLAND, Ore. (KOIN) — You’ve set the bar high for your Memorial Day weekend. How can I know? Because you are reading this article. You heard us talk about the rain coming this weekend but you hope to read the opposite.

Did you know that it rains 40% of the time in Portland on Memorial Day? Records dating back 80 years for Portland International Airport show us that on average the maximum temperature in Portland on May 31 is just 69 degrees and about 21% of the time we will have more than a tenth of inch of rain. Only 8% of the time our maximum temperature reaches the 80s.

The forecasts

Friday, the gateway to the weekend, will look more like a portal to March-like weather, cloudy, chance of rain and highs in the mid to upper 60s. And if you’re going to be in a parade around Portland this weekend, you’ll wish you could get some of that sunshine back with the 80s we had in May of last year.

Most of Friday, the sky will look like it wants to rain without anything significant falling from the sky. This should be just enough to flush the soil and produce almost a tenth of an inch.

Overall, the rain will be light with this front. Unless of course you spend time in the foothills or western slopes of the Cascades. Then something called lift will help improve those showers and squeeze a few more drops from the windward side of the foothills.

Thunderstorm Outlook Friday

Eastern Oregon in Idaho may not be ideal for hiking or rafting on Fridays with all the right ingredients for thunderstorms.


On Saturday, Portland could have a fire hose reckoning, possibly receiving nearly an inch of rain before the day is out thanks to a heavy-duty low-pressure system.

Temperatures will be nearly 10 degrees below normal in the upper 50s to lower 60s, which only happens about 14% of the time.

The good news from this rainy day is that liquid gold wealth will be better distributed in Oregon. Expect gusty southerly winds along the coast.


Temperatures remain below normal in the upper 50s to low 60s. Meanwhile, the rain will slow to a touch of drizzle by late Sunday evening.

If you’re heading for mountain passes from Saturday to Sunday, that’s when you’re likely to encounter falling snowflakes. If you head to Timberline for a quick jaunt and a view up to the Three Sisters, you won’t find much to see from afar.

Remembrance Day Monday:

Monday starts out drizzly but should dry out quickly by noon or lunchtime. There is a possibility of sunshine to conclude the vacation. Monday’s highs are moving rapidly towards the mid upper 60s.

Whether you’re enjoying the rays of the sun or the drops of rain, we wish you all a thoughtful and peaceful Memorial Day weekend.
