'Alien-like' lenticular clouds put on another show

Lenticular clouds have been known to put on some dazzling displays around here, and Tuesday night was no different.

Marcy LaGagnier snapped these photos of a lenticular cloud display over the Cascades from Leavenworth.

They're caused when the air flow is just right so when it flows over Mt. Rainier, the air gets pushed upward where it cools and condenses into clouds.

Depending on how smooth the flow is, you can get some amazing clouds formations that sometimes have actually been mistaken as part of UFO sightings. (And you can see why -- especially since they hover in place.)

The clouds are usually a sign of rain within 24 hours because typically the moist flow that precedes a storm around here is the perfect set up for these clouds.

And sure enough, I can hear the pitter-patter of raindrops as I write this blog on Wednesday evening!
