In With The Rains, Out With The Flames

Most of our wildfires are actually started by lightning, but that doesn't mean you can have a tannerite party during a red flag warning.,

Hey everybody! I’m finally back from summer camp, and while I had an amazing time there, I am very excited to sleep in my own bed, practice lots of saxophone, get a job (hopefully related to meteorology), and, of course, get back to writing weather blogs. I came back in the nick of time, as we’ve got a lot to talk about today.

As I'm sure you have no doubt figured out by now, this summer has been one of the worst fire seasons in Washington's history. Many news stations said that the Okanogan Complex Fire by Omak was the largest in the state's history, but this is not true, as the many fires here have not merged into a single large fire. That title is reserved for the Carlton Complex Fire of 2014 (wow, we really are getting burnt up, aren't we?). I attached a couple amazing shots below of the Wolverine Creek Fire, a fire that has been burning since June 29 and has now burned over 50,000 acres. These pictures are from the USDA (United States Department of Agriculture) Flickr page.

And here is a map of all the fires occurring over Washington and Oregon. It looks like all of Northeast Washington is on fire!

Now, let's take a look at our mega-summer-storm. I can't ever remember seeing a storm this strong this early in the season. Even if it were November, this would still be a sizable storm for our region. But August? Good golly.

At 4 am, the storm was off our coast and travelling to the NNE. This is a perfect track for regionwide high winds... and it is the same path that our storm last December. I have a blog on that December storm here and you should all read it because it has an intense video of me in the storm. It's the same general track as the November 13, 1981 windstorm, the December 12, 1995 windstorm, and yes, the infamous Columbus Day windstorm of 1962.

Take a look at the nice, tight bent-back occlusion in the image below. The low center is right in the middle of that spiral.

As the morning went on, the low moved further and further north and kept its intensity. One of the great things about our new coastal radar is that you can sometimes see the low centers of these types of storms as they swing on by, and you can clearly see the center with this storm less than 100 miles off the mouth of the Columbia River.

At 9:30, the storm is moving on inland, and right now (10:56), it is crossing the Olympic Peninsula just to the south of Cape Flattery.

Winds are reaching their peak now and will remain pretty strong until around 1 or so. After that, they will die down, but things will still remain pretty blustery around here. We have a high wind warning up (when was the last time Seattle had one of those in August?), but given the forecast wind speeds (40-50 mph gusts), a wind advisory would be more appropriate. We just have the warning since we are in the summer and weather like this is practically unheard of. I mean, take a look at all the weather warnings over our area. I've never seen anything like that in the summer.

Rainfall from this particular storm will total around 0.5 to 1.5 inches in the lowlands, with several inches in the mountains, especially the North Cascades, putting an end to any fires there. Though the majority of the rain will not make it over to Eastern Washington, some rain will fall, and this, coupled with high humidity, will be a tremendous help for firefighters fighting the wildfires in NE Washington. They will have to battle with strong winds though.

The rest of the week looks showery, but as far as major storms go, I don't see anything in the near future.
