Fall doesn't technically start until Sept. 21, but it's arriving early this year as a front moves into the region this weekend. KNKX weather expert Cliff mass says it'll bring cooler temperatures and rain. 

"We've had this run of dry weather that extended out for months. Temperatures have been above normal. We've even had smoke and ash," Mass said. "But everything's going to change this weekend."

Temperatures will plummet on Sunday with highs only in the low 60s. It'll look about the same on Monday with much of the rain coming then.

"It was about time this happened. The sun is now getting weaker. The nights are getting longer, and eventually it had to catch up with us," Mass said.

And while we've been experiencing those dry conditions in the Pacific Northwest, people to the south have seen much more rain and wind. On Mass' blog this week, he examines the forecasting that lead up to Hurricane Irma, in particular. That's the storm that hit Florida. 

"Standing back, the forecast for Irma was a triumph," Mass said.

Mass says the European Center Model was forecasting the storm 10 days ahead of landfall. Then two to three days in advance the storm, the models show the sharp turn it would take. Mass points to technology upgrades and an improvement in forecast models over the last few decades as reasons for such precise information.

"We have sophisticated weather satellites that not only get pretty pictures, but can actually sense the temperatures and winds at various levels in the atmosphere. In the old days, we didn't know what was going on over the oceans, but today we know everything that's going on with the ocean," Mass said. "Our models have gotten much better. Our global models have higher and higher resolution and better physics."
