The chill is here to stay

It has been a long and chilly spring. Most temperatures have been unseasonably cool. June has brought a spat of near record-cold high temperatures. So some of you may be asking...and perhaps screaming...why?

Blame our good friend La Nina. This phenomenon - the cooler-than-average Pacific waters - cause worldwide changes to the atmospheric winds and weather patterns. It's bringing cooler-than-average temperatures into the Northwest. The good news is that La Nina is weakening. So we'll see a nice warmup for the summer, right?

Not so fast. Even though La Nina is breaking down, the weather patterns created by it have a sort of momentum...and that momentum means that this cool pattern may last well into summer. That's not to say it's going to be cloudy and cool all summer. Our bright July sunshine should arrive right on schedule. It just could be a bit cooler than what you might expect.

And one final note - I need to add an asterisk to all this (I'm a meteorologist, you know I had to do it). Our expectation for cooler-than-average temperatures this summer is based on the long-range outlook from the Climate Prediction Center. But it's just that - an outlook. It may still change.

We'll keep you posted!
