Watch: Multiple lightning strikes stream from volcanic eruption in Chile

There are some pretty incredible photos and videos of the Calbuco Volcano eruption in Chile. 

The eruption sent an ash plume high into the sky where it spread out to make an amazing cloud display that lit into brilliant colors at sunset.

Here is one time lapse video:

But aside from the dramatic cloud formations, it also created quite a bit of lightning:



Volcanic lightning has been somewhat of a scientific mystery over the years, with no set declared conclusion how it forms.

Here are two articles that delve into the science, One from the Smithsonian, the other the other from MIT Technology Review.

Smoke from Siberian wildfires turns Northwestern sunsets a fiery red

The scenes have almost felt like they're out of Hollywood imagination -- brilliant red sunrises and sunsets the last couple of days around Western Washington.

Why so red? It's a byproduct of the massive wildfires that recently burned a large area in Siberia.

The atmospheric winds are aligned this week to carry the smoke across the Pacific Ocean and into the Pacific Northwest.

First up, to get an idea of just how much smoke is in the atmosphere, look at this visible satellite image taken on April 14 of the southeastern Siberia area where the wildfires got out of control:

Where did the smoke go? This graphic is a model trajectory tracing back the air pattern across the Pacific Ocean over the past week. Note the air from the wildfires makes somewhat of a bee line toward Seattle (with a brief stop for a loop-de-loop in the central Pacific:)

Amazingly the smoke is still quite intense when it gets here -- check out this high-resolution satellite image from Saturday and note the haze over Washington and British Columbia:

Just like a song that has the same verse over... and over.... and over...

and over....

Here comes the fresh 90 day forecast from the NOAA's National Climate Prediction Center and the story...is the same. In fact, it might be even more declarative: May is going to be hot and dry. Late spring is going to be hot and dry.

The summer is going to be hot and dry.

The autumn will be... warm.

Monday was another stormy day around the Puget Sound region, but it appears it was a bit extra-stormy on the Kitsap Peninsula.

Elaine Lunyou-Blankenship's husband snapped this photo of what appears to be a weak tornado that touched down west of Bremerton Monday afternoon around 4:15 p.m.

Lightning leaves a rather twisted scar on Olympia tree

I have to admit even being a weather geek, I hadn't really thought much about how lightning strikes a tree, but this photo taken by Barbara Engelhart got me wondering how this particular lightning bolt chose its path to the ground.

"We had an interesting lighting strike here in Olympia on Wednesday afternoon," Engelhart wrote to me. "It sounded like a bomb went off or propane tank explosion. After looking around our property I came across one of the fir trees that had a spiral pattern on it and bark and wood gouged out."

As Seattle sits on a streak of four of the past six month setting records for warmest on record, a new University of Washington study pins the "blame" (or "credit" depending on your opinion of endless 50+ degree days in winter) on a large and persistent pool of warm water that has been entrenched in the Pacific Ocean off our coast.

The waters have been averaging about 3-7 degrees above normal and researchers at the UW say it's been a major factor in the West Coast's recent warm stretches, and in turn, the winter to remember (or forget) across the East Coast.

It's sad that something so beautiful has to be so destructive...

Astronaut Samantha Cristoforetti snapped these photos of Super Typhoon Maysak as it swirled in the western Pacific Ocean earlier this week. The photos show a pronounced eye center of the storm that at the time was a Category 5 storm -- the top rung of the Saffir-Simpson Wind Scale.

Early risers to be treated to a lunar eclipse Saturday

Editor's note: Didn't get to see the lunar eclipse? Check out what you missed in our Blood Moon photo gallery!

SEATTLE -- Usually Saturdays are made for sleeping in but if you want to get up super early this Saturday, you might just catch a lunar eclipse.

Scientists expect totality - when the full moon is completely obscured by Earth's shadow - to last just several minutes, beginning at 4:57 a.m. PDT. Most of the eclipsed moon should appear reddish-orange.

Watch: Lightning strikes two jets on approach to Sea-Tac Airport

Watch: Lightning strikes two jets on approach to Sea-Tac Airport

SEATTLE -- Some of the people on their way into Seattle Wednesday evening got quite the hello from Mother Nature as lightning struck two different jets as they approached Sea-Tac Airport.

University of Washington student Owen Craft was out in the University District trying to film lightning strikes as a thunderstorm moved through and caught the two massive bolts as they passed through the planes' fuselage.

"I was stunned for a second because I couldn't believe what I just saw," Craft said. "After the second (plane) got hit, I knew I was on to something spectacular!"

Surf's up? Massive 'wave' cloud spotted near Boeing plant

Chuck Benson snapped these rather strange looking clouds outside the Boeing Everett 87 building Thursday morning.

It looks like the surf's up in the sky, and in a way it is. These are called "Kelvin-Helmholtz" clouds, caused when you have wind shear --that is, layers of air moving in different speeds or directions. As those layers interact with clouds, you can get turbulence that causes these impressive wave-like formations to occur.

Add it to the pile: March sets record for all-time warmest in Seattle

The end-of-the-month blogs these days seem to write themselves, just change the month...

For the fourth time in the past six months, Seattle has set the record for all-time warmest month. March 2015 now joins brethren October, December and February as the warmest on record at Sea-Tac Airport (70 years of data) by average monthly temperature -- found by taking the high and low and divided by two.

Time lapse video shows how those spooky 'hat' clouds form on Mt. Rainier

The sometimes-eerie-looking "Hat" clouds -- officially known as lenticular clouds -- are no stranger to Mt. Rainier. But while to many it might just look like a cloud frozen in time, there is actually quite a bit of air movement involved in making the clouds.

KOMO News photographer Mitch Pittman was up hiking in the Cascades recently and managed to get this amazing time lapse video (above) of a lenticular cloud sitting atop Mt. Rainier. The video is a great illustration of the flow that goes into making the cloud's lens-type feature.
