Scott is not only the staff meteorologist for, but is also a content producer for the entire site which helps keep him busy during the five days of the year when Seattle's weather is uneventful.

Scott also is the author of the Partly to Mostly Bloggin' weather blog both here at KOMO and at our sister station in Portland,

The blog was recently honored with a 2nd place finish in the regional "Best Specialized Blog" category in the 2009 and 2011 Society of Professional Journalists annual awards.

Scott graduated from the University of Washington in 1994 with a degree in Atmospheric Sciences and started at KOMO two days later as Steve Pool's weather producer.

Scott took a three year hiatus in the late 90s to go work for the company that created KOMO's weather software (remember the green weather wand?) but missed KOMO's unique lunchroom coffee blend of java and grounds and came back to KOMO full time in January 2000 as both a staff meteorologist and a news web content producer. (Yes, he was 9 years ahead of the hybrid craze!)

These days, Scott writes the weekday afternoon weather forecast on's weather site, as well as original content for his weather blog and weather and science-related stories for the home page.

Scott's also a published author. He co-wrote the book "Somewhere I Was Right" with Steve Pool -- a fun look at the zaniness that is Northwest Weather. You can find more information about the book at

He was born in Port Angeles, but considers himself a "child of the Northwest", having lived in several places along the Pacific Coast through childhood as the son of a Coast Guard search and rescue pilot, before returning to the Seattle area in 1990. He's a big Mariners' fan -- that's how he met his wife Michelle -- and loves fantasy baseball. (He welcomes any drafting tips or hot prospect information you might have.)

He's also the self-proclaimed "Spokesperson for Seattle's rain fans" -- Scott's not too happy when it gets close to, or above 80 or when the rain stays away too long -- something that he shares with thousands of Seattleites who might possibly constitute a silent majority.

Scott's not on TV, but you can occasionally hear him on KOMO 1000 News when the weather is ornery, or even sometimes see the back of his head when Steve is live in the weather center (or, it might be an intern. No, Scott doesn't change his hair color every day). He did land a starring role in the movie "Life or Something Like It", which was the Angelina Jolie movie filmed in KOMO's newsroom, as "Head Behind Computer Monitor Number 12" for six seconds in one of the newsroom scenes.

He's married with two young daughters..

Weather Time lapse videos show off beauty, power of nature Time lapse videos show off beauty, power of nature (Video)
West coast photographers have been busy getting great videos of the power and beauty of nature lately, so it's a perfect time to feature a few in the blog.

This first one (above) is from Arizona storm chaser Mike Olbinski, who spent quite a bit of time traversing the Midwest and Desert Southwest compiling the video for his film, which has over 45,000 images.

I suggest playing the video full screen on 4k resolution if you've got the bandwidth for it. It's amazing.
Weather Even the most in-shape firefighters affected by Seattle's heat wave Even the most in-shape firefighters affected by Seattle's heat wave
Firefighters, by the nature of their job, already have one of the hottest jobs you could imagine. But what about when Mother Nature brings blazing temperatures on the outside as well?

When a massive fire broke out in an apartment building on Queen Anne Hill on July 1 , firefighters were called in from as far away as Redmond, Shoreline and Bellevue as temperatures were sitting at 90 degrees. Why so many firefighters from all over? To make sure there were plenty on hand to rotate in and out so firefighters didn't overheat.

And with 90 degrees suddenly common this summer around Seattle, I wondered how local fire departments were dealing with the relentless heat, and how they manage to keep firefighters cool when their surroundings are burning up.
Weather Seattle was oh-so-close to having an officially wet July Seattle was oh-so-close to having an officially wet July
The skies opened up, the rains poured down, and Seattle obliterated a record for wettest July 26th on record with nearly an inch of rain in a few hours!

Were you actually in Seattle Sunday and are wondering, "what's Scott typing about? It rained for a few minutes, but record?!?" you're not alone.
Weather This video shows why Midwesterners laugh at Seattle storms This video shows why Midwesterners laugh at Seattle storms (Video)
Sunday's scattered thunderstorms probably qualified as a relatively stormy day around, here, especially by Northwest standards. Some spots had some torrential rain, and we had a few reports of hail, none super large though.

Western Washington is fortunate that our marine climate makes actual severe weather systems just about impossible to form; and what thunderstorms we get pale in comparison to just about any other thunderstorm you'd find east of the Cascades.
Weather Worldwide strengthening El Nino giveth and taketh away Worldwide strengthening El Nino giveth and taketh away
You've probably already heard the news, especially if you've read my blog anytime in the past six months, that El Nino is here and getting stronger. Scientists say there is a greater than 90 percent chance of El Nino this winter and an 80 percent chance it lasts into the spring.

El Nino's around here have a hallmark of bringing a winter that's not only warmer than usual but drier than usual as well. This plus the infamous "warm blob" of ocean heat offshore and this winter may already be a lost cause for much in the way of lowland snow and puts serious doubts into getting much in the way of mountain snow either.
Weather Restless Convergence Zone brings rain 15 different times to Everett Restless Convergence Zone brings rain 15 different times to Everett
Not that many around here use an umbrella to begin with, but if we did, they would probably be mechanically worn out this weekend, at least if you lived around Everett.

A weak Puget Sound Convergence Zone hung out over a narrow band of Snohomish County from start to finish Saturday, but like a 2-year-old at a restaurant, it wasn't content to just sit still.

The zone was only a few miles wide and drifted north and south from about the King-Snohomish County line back up into Downtown Everett… and back again as the corresponding north and south winds pushed back and forth like a tug of war.
Weather Weekend rain showers dripping with irony for Seattle Weekend rain showers dripping with irony for Seattle
We're in the midst of one of the hottest and driest summers in recent memory. Seattle hadn't had measurable rain since June 28 and hasn't had significant rain since June 1. The last time it rained on a weekend? April 25.

So naturally, one of the weekends it rarely rains is the one weekend when it does rain.

The last weekend in July is statistically the driest in Seattle with the first weekend in August no slouch. It's rained only about 9-12 times in the past 122 years on those dates -- or about once every 10 years.

In soggy Seattle, that's the best odds you can ask for. That's why Seafair's biggest events are this time of year; why Torchlight Parade is this Saturday evening and why savvy locals know to rush to book their outdoor wedding or party the instant the last weekend in July becomes available on the venue's calendar.
Weather Why has it been so warm so long? This picture says 1,000 words Why has it been so warm so long? This picture says 1,000 words
We're coming up on 17 months in a row with above normal temperatures on average, and several of those months have been the warmest on record in Seattle. This summer, we've had dozens of days in the 80s, already the second-most 90-degree days on record with August still to come. The coldest low temperature we've had in the entire month of July? 57. The average low is 55.

People have been asking me why has it been so warm for so long? Well, NOAA did me a favor and sent out this handy graphic which shows exactly why: The warm Pacific Ocean.
Weather Sharknadoes -- COULD THEY HAPPEN HERE?!? Sharknadoes -- COULD THEY HAPPEN HERE?!?
Scott's note: It's SHARKNADO DAY! Sharknado 3 airs tonight at 9pm on the SyFy Network. To celebrate, the blog today has encore entry from when the first one aired two years ago. And if you want to watch the latest installment along with me, I'll be Live Tweeting during the show on my Twitter page @ScottsKOMO

Story originally published July 12, 2013:




Social media and water coolers were abuzz Friday with the next DVD blockbuster sci-fi (emphasis on the 'fi') movie "Sharknado" that aired on the Sy-Fy channel Thursday night.

But this jaw-dropping (jaw-clenching?) story brought up an important facet of meteorological studies that have been historically and woefully underfunded: The science of shark-infested tornadoes from hurricanes that strike the Pacific Coast of the United States.
Weather Seattle warm stretch to last into October ... 2016?!? Seattle warm stretch to last into October ... 2016?!?
OK, I admit it, I'm cheating the headline. It's nearly the same headline I wrote last month in my blog, only it said September instead of October. But the new monthly maps have been updated, and -- surprise -- the warm blobs in the forecast remain intact through not just this fall, but next autumn as well.

In the short term, there still remains very high confidence the Northwest will have a hot remainder of summer, and, well, it was sure right about the first part of summer.

We've already had as many hot days so far this year than we average in an entire year, shattered the record for hottest June on record, and the first half of July in on the pace to set the same record (although there are some signs July will back off the flamethrower switch after the weekend. More on that in a bit.) In fact, if the second half of July were to mirror the first half, we'd be talking about hottest month in Seattle history! (But as I just teased, that seems unlikely.)
Weather Watch: Mt. Rainier, Mt. Baker show off for Mother Nature Watch: Mt. Rainier, Mt. Baker show off for Mother Nature (Video)
The mountains around here can sometimes create their own weather, and these two time lapse videos prove it.

The time lapse video above was taken by Michael Reid of Mike Reid Photography at Mt. Rainier. Note the dramatic lenticular clouds that ebb and flow as the sun rises at the state's tallest peak.
Weather Smoky skies make for surreal scenes around Northwest Smoky skies make for surreal scenes around Northwest (Photo Gallery)
If the smoky skies this week haven't been noticeable to you during the day, it's certainly been a factor in the evening sunsets, as it's been turning the sun a brilliant red the last few nights.

The smoke is coming from a massive wildfire burning near Pemberton, B.C.

Since Sunday, the upper level winds have been out of the north, pushing the smoke south across the border into Washington as you can see on this satellite image from Wednesday.

(Note the chalky gray streaming out of the mountains just across Vancouver Island on the B.C. Mainland and sinking south:)
