Dry Streaks End Tonight!

Dry Streaks End Tonight!

FINALLY! After 56 days of no measurable precipitation for Seattle and 57 for Portland, both streaks will end tonight as a relatively strong front moves through the area. The front is associated with an upper-level trough/associated ~995 hPa surface low currently centered near Haida Gwaii. The water vapor imagery below looks more reminiscent of a wintertime system than something we’d see in August. The front is visible in even greater detail with our brand new GOES-16 satellite, which is still…

The Great American Eclipse of 2017

The Great American Eclipse of 2017

I was in 8th grade when I first learned about the Great American Eclipse. Mr. Pearsall, the science teacher at Washington Middle School, gave us a handout on the eclipse and told us not to miss it. 11 years later, I live 25 miles from the path of totality, and I wouldn’t miss this eclipse for the world! I hope Mr. Pearsall is able to see this eclipse as well. The Great American Eclipse is the first eclipse since 1918…

At Last, Rain Is In The Forecast!

At Last, Rain Is In The Forecast!

It’s not much, and not everybody will get wet. But for the first time nearly two months, rain is in the forecast for parts of the Pacific Northwest! The summer of 2017 has been extraordinarily dry for the Pacific Northwest. Following a soaker on June 15 that dropped 0.42 inches at Portland and 1.05 inches at Sea-Tac airport, both places saw a few drips on the 16th and 17th (respectively) and have been bone-dry since. On Monday, Sea-Tac airport recorded their…

Smoke Keeps a Lid On Record Highs

Smoke Keeps a Lid On Record Highs

Everything seemed right for record high temperatures at Portland. We had offshore winds to prevent any cooling from the Pacific Ocean and a massive ridge overhead with insanely warm temperatures aloft. But with extreme heat comes extreme fire danger, and fires have erupted over the Pacific Northwest and British Columbia over the past few days. Smoke from these fires decreases the amount of solar radiation that can reach the surface. Solar radiation is expressed as units of power per unit…

Record Heat on Tap + Thursday HVC Kitchen Forecast

Record Heat on Tap + Thursday HVC Kitchen Forecast

This past Sunday, I headed up to Hidden Valley Camp, an old-school summer camp in the Cascade foothills of Snohomish County, WA for “Visitor’s Day,” a day where families of campers and other visitors can visit the camp and interact with campers and staff. I’m a longtime former HVC camper, camper-leader, and staff member (baker and group counselor), and over my years at HVC, I developed a reputation as a weather forecaster, so many of my visitor’s day conversations revolved…

Wildfires Rage On In California and British Columbia

Wildfires Rage On In California and British Columbia

It’s been a boring past few weeks for Pacific Northwest weather bloggers. Portland, Seattle, and many other places around the Pacific Northwest have now gone a month without any measurable precipitation. For much of the past month, a large ridge of high pressure has been plopped right over us, shunting the storm track to the north and keeping us warmer and much drier than normal. When we get an extended period of warmer and drier-than-normal weather in the summer, it…

Weather Models Are Finally Up!

Weather Models Are Finally Up!

FINALLY, after several days of coding and several months of troubleshooting, WeatherTogether has its own model charts! Before I go any further, I have to thank Quinn Abrahams-Vaughn for writing some html and javascript pages to get me started with model visualization and Derek Hodges for his guidance on shell scripting and crontabs to automatically download model data. Below, I’ll give the motivation for this project, demo some charts, and lay out the path forward from here. Motivation: Create engaging…

Record Heat Today, Much Cooler Tomorrow

Record Heat Today, Much Cooler Tomorrow

The first major heat wave of the year is living up to the hype! Portland and Salem hit 98 and 101 respectively yesterday, and today, they simply switched highs. According to Mike Newman (a fellow weather buff from the Portland area), today’s high of 101 at the Portland Int’l Airport was just 1 degree below the all-time June high of 102. Thankfully, temperatures will come crashing back down to Earth for everyone west of the Cascades tomorrow courtesy of a…

Record Heat This Weekend?

Record Heat This Weekend?

By now, I’m sure most of you have heard about the record heat in California and the Desert Southwest. On Sunday, San Francisco obliterated its previous heat record of 86 degrees with an unbelievable 97-degree high, and yesterday, Palm Springs reached an egg-frying 122 degrees! Phoenix even had to cancel nearly 50 flights yesterday due to the heat. So far, the Pacific Northwest has escaped this record-breaking heat wave. But that will change this weekend! The chart above shows the…

Get Ready For June Gloom!

Get Ready For June Gloom!

Sorry for the post hiatus folks! I just got back from a week-long trip with my folks to Cabo San Lucas and had a great time fishing, beach-combing, dancing, and eating all sorts of delicious food over there. We’ve had a pleasant start to June, and the past two days have been simply exceptional! Yesterday, Portland hit a high of 86 degrees under mostly sunny skies thanks to a strong ridge of high pressure centered over the Intermountain West. This…
