Advection Fog Over Lake Washington!

Advection Fog Over Lake Washington!

Folks west of the Cascade crest smashed record high temperatures today as a Pineapple Express continued to pump extremely warm and moist air originating from the Hawaiian Islands into the region. The fact that today was relatively calm and dry definitely helped, as we were able to get a little more solar insolation and didn’t have any winds aloft mixing cooler temperatures down to the surface. The chart below shows today’s maximum high temperatures. Sea-Tac hit 68 degrees today, crushing…

Everything You Need To Know About Atmospheric Rivers

Everything You Need To Know About Atmospheric Rivers

With a strong atmospheric river underway, I thought I’d take some time to delve a little deeper into these phenomena. In this blog, I’ll cover the basic characteristics of an atmospheric river, how these atmospheric rivers form, and a brief summary of how they relate to the Earth’s heat budget. Throughout the blog, I’ll use two of the largest atmospheric rivers of the past decade – the November 6-7 atmospheric river and the December 2-3 “Great Coastal Gale” (one of…

An Atmospheric River Fiesta

An Atmospheric River Fiesta

Wednesday, January 27, 2016 1:41 am Yesterday, I wrote about the Eastern third of the country and how much of that region was profoundly affected by a major blizzard that halted over 13,000 flights and caused 3 billion dollars in damage. Now, the weather action has shifted back to our neck of the woods, and while we won’t see anything historic over the next week like what was witnessed in some states back east, the entire West Coast looks to…

Tons Of Rain!

Tons Of Rain!

Thursday, January 21, 2016 5:45 p.m. It’s been pretty wet today. I could explain it with satellite imagery, models, maps, and all that jazz (and I will), but all you really needed to do was to go outside and look at the size of the puddles, both on the road and off it. There was an astonishing amount of puddles today. Credit: National Weather Service Let’s take a look at some 24-hour rainfall totals around the region. At least two…

Torrential Rain In the Olympics, Drizzle In Everett, And Inadequate Rainshadow Communication

Torrential Rain In the Olympics, Drizzle In Everett, And Inadequate Rainshadow Communication

Friday, November 13, 2015 12:57 pm Credit: PRISM Group and Oregon Climate Service. Retrieved from Reddit (yup!) One of the most fascinating things about Pacific Northwest weather is how much our local terrain influences our climate. Just in the state of Washington, we have two mountain ranges that get gobs of snow, a massive ocean off our coast, an inland sea, a temperate rainforest, a desert, and everything in between. This event has been a great example of how terrain affects rainfall,…

The Moisture Train Of Doom

The Moisture Train Of Doom

Thursday, November 12, 2015 9:53 am Everybody talks about atmospheric rivers. Atmospheric river here, atmospheric river there. And while the “atmospheric river” term is certainly useful and is used in scientific literature, it also comes across as a bit of a euphemism. It sounds so nice and tranquil, like a stream flowing through the heavens, when in reality, it could lead to a stream flowing through your living room. I’ve thought of different names to call these pesky atmospheric rivers,…

Muggy and Rainy

March 11, 2013 10:40 P.M. I tried to be creative and somehow link the post I made ten days ago to this one, but when I typed “Lil’ Wayne Rain” or even “Lil’ Wayne Precipitation” on Google Images, all I got was Lil’ Wayne making it rain (aka throwing money in the air, because that’s what it takes to become a highly esteemed individual in 21st century pop culture. Kids these days…). In any event, we are seeing that same sort…

Friday, March 1, 2013 11:39 A.M. Weezy approves of the weather. Well everybody, it has been awhile. I had a midterm today, and I have midterms Monday and Thursday next week. It never ends! However, I have a brief break between classes and I thought I’d post a blog instead of eat some lunch. I’m not hungry. Although we don’t get super humid like the East Coast, we can get relatively humid on winter days when some subtropical moisture gets entrained in…

Storms!

Storms!

Friday, November 16, 2012 8:50 A.M. I’m happy. You know why I’m happy? Because we will finally see a string of strong storms that will streak from ocean to peak through next week. Now that was clever. Let’s look at the timeline for our storms.  Our first storm comes in on Saturday morning. This one looks pretty impressive in the model, but the front will stretch out and weaken before it hits the Western Washington lowlands. It won’t be a…

Snow Looking a Bit More Likely

Snow Looking a Bit More Likely

Thursday, November 17, 2011 12:51 P.M. I’ve got some great news for all you snow lovers! The new 12z model runs came out this morning, and both of our high-resolution models at the UW are pointing to a bit of snow in the Western Washington lowlands! This is the first run that has really shown some snow, so I am not completely sold on the idea yet, and the snow  predicted is pretty light and spotty, with Seattle not getting…
