clouds

On Thursday, the Grand Canyon literally filled with clouds, and the National Park Service posted a time lapse video of the rare event.

This "total cloud inversion" occurs when cool, damp air gets trapped in the bottom by warm air.

The phenomenon typically only takes place every few years.

No this isn't photoshopped, just a perfect day for a wedding.

A couple in Idaho was fortunate enough to have this heart-shaped cloud formation as the backdrop during their ceremony. And just in time too, as it reportedly rained during the reception.

Lightning is awesome and today the Department of Awesome Natural Phenomena presents a form of lightning we'd never heard of before: blue jet lightning. This is a form of upper-atmospheric lightning, believed to be electrically induced forms of luminous plasma. It's also known as a transient luminous event (or TLE) because the various types of electrical-discharge phenomena in the upper atmosphere lack several characteristics of the more familiar tropospheric lightning.
