What happened?

So much for the hot brutal summer in Seattle.. it's been anything but. Even the most recent forecast for the three days we're on says hot.. it's no where near hot and won't be for the foreseeable future.. what happened? Is there a reason it's been so off this year?

June

Lol it says June hotter than normal yet it’s been chilly in the 60s and even mount hood got snow twice!!! It dumped snow twice in June!!

Yes it has

It has been freezing where I live, Portland hasent reached 63+ for a few days, with our lows at 44-52!

Summer Temps

I live in Josephine County, Southern Oregon.
We definitely did not have the "Hottest Summer" in record.
It seemed like summer had a hard time getting settled early on and then we only had a couple of days that peaked around 100 degrees.
Very mild for this area.

Oregon Weather

There is a saying in Eastern Oregon " If you don't like the weather, wait 5 min. and it will change ". So true, especially in Spring. :)

Duh

Everyone says that about where they live. Too cliché.

Cliche

They don’t say that where I live. We get like 353 days of sun a year.

NE Oregon Weather forecasts

To carry on with that theme, my Grandma always said that people who try and predict the weather in The Grande Ronde Valley are either crazy or from out of town!

Question for Editors

Is it true that the PNW is one of the hardest places in the world to predict the weather?

Weather forecasting in PNW

Not really. If you can see Mt. Rainier, it's going to rain. If you can't see Mt. Rainier, it's already raining.
