Ethereal they may look but cirrus clouds have heavy hearts. The clouds are made from ice crystals grown around tiny particles of metals and minerals.

Via ArchieMcphee:

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.

A messy winter storm is moving across the eastern half of the United States, threatening to delay drivers and fliers right before Thanksgiving Day, one of the busiest travel times of the year.

Weather forecasters say a few key atmospheric components joined forces to create this meteorological misery.

The storm is actually the same upper level low-pressure system, or trough (essentially a dip in the jet stream), that tore over the Southwest over the last few days, Brian Hurley, a meteorologist with the National Weather Service said. The storm dumped nearly a foot of snow in parts of northern New Mexico, prompted hundreds of flight cancellations in Texas and caused several deadly traffic accidents across the region, the Los Angeles Times reported.
