Gorgeous 'fog bow' captured in Cle Elum this spring

Gorgeous 'fog bow' captured in Cle Elum this spring

If this looks rather strange for a rainbow, it's because it's not quite a rainbow...

Instead, this photo by Larry Rogers in Cle Elum depicts a "fog bow."

Fog bows are generally seen as an arc of dense fog along the edge of a fog patch. The physics is somewhat similar to traditional rainbows in that the bow is caused by sunlight refracting inside water droplets.

However, unlike rainbows, where the raindrops are large enough to refract sunlight into its individual colors, the water droplets in a fog bow are much smaller, and so the refractions aren't as precise.

Thus, the way the light scatters from a fog bow, you get a lot of color overlapping, and more of a hazy white bow instead of the colorful rainbow.

Watch: Time lapse video of gorgeous Mt. Rainier lenticular cloud

They're sometimes mistaken for aliens, but really, it's just a sign rain might be on the way.

Luke Meyers just recently published this time lapse video of a rather strange-looking lenticular cloud over Mt. Rainier last March. It's a good illustration of how they form -- the clouds look stationary but there's quite a bit of movement in them as air rises just enough to saturate, then dries enough as it sinks to "go invisible" again.

'Tis the season for brilliant 'fire rainbows'

NOTE: Story orignally posted May 8, 2013

The first week of May is probably better known around here as the Opening Day of Boating Season but did you also know it's when we kick off the fire rainbow season?

Fire rainbows, or more officially (and more boringly) known as "circumhorizonal arcs" are caused by ice crystals in the thin, distant clouds being at just the correct angle to refract the sunlight into the colors of the prism.

Ron Glowen, now of Arlington, Wash., just sent me these photos that were taken in June of 2006 while visiting his hometown of Spokane.

Not sure I've ever seen a photograph that captures the beauty and power of weather in one singular shot.

Snohomish's Benjamin Jurkovich, part of the JWSevere Weather Chasing Team has been out storm chasing in the Midwest for the past few weeks and he's had his share of twisters, super cells, and other images that define Tornado Alley in the spring.

But this one he got near Wiley, Colorado Saturday afternoon might be the most unique in his portfolio -- a tornado at the same time as a rainbow.

A few easy tips that can save your life on the water

A few easy tips that can save your life on the water

As sunshine and 70s become more common this time of year, so do the spontaneous trips out to enjoy the warmth out on the water. And with that comes the busiest time of the year for water rescuers.

Sadly, May is the month with the highest amount of water-related fatalities in the Northwest and this year is no different.

SEATTLE -- The full moon made quite the appearance Sunday night and local photographers were at the ready.

We received a few photos with the moon lined up with the Space Needle.

But the photographers didn't have to "luck" in the shot. Did you know there are tools out there to help you be ready for these kind of amazing photos?

An impressive temperature streak in Seattle is still going strong…

April finished up with an average temperature of 51.4 degrees in Seattle -- 1.1 degrees above normal, making it the 14th consecutive month with above normal temperatures.

STEVENS PASS, Wash. -- The paltry snowpack at Stevens Pass this winter is now officially melted out.

While there is still a dusting of snow around some parts of the pass area, the measuring station there measured less than 2 inches of snow water equivalent on the ground Tuesday -- the official definition of when the snowpack is considered melted out, according to University of Washington research meteorologist Mark Albright.

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:

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:
