If you are wondering where all this snow is coming from.

If you think this is going to stop me and my brother from attending the Giants/Eagles game tonight, you’re wrong.  Dead, soaking wrong.

How come everyone but me is going to the game tonight!?!?

“Make hot cocoa. Bundle up. Tell your friends. The best meteor shower of 2009 is about to fall over North America on a long, cold December night.

A new Moon will keep skies dark for a display that Cooke and others say could top 140 meteors per hour. According to the International Meteor Organization, maximum activity should occur around 12:10 a.m. EST (0510 UT) on Dec. 14th. The peak is broad, however, and the night sky will be rich with Geminids for many hours and perhaps even days around the maximum.”

Weather Geeks Champion New Armageddon-Worthy Cloud

In hill country from Iowa to the Scottish Highlands, sky-gazers have reported some strange, ominous-looking clouds of late. Dubbed undulatus asperatus (turbulent undulation), the atmospheric anomaly could be headed where only 80-odd clouds have gone before: into the International Cloud Atlas. If it makes the cut, asperatus will be the first new addition in more than 50 years.

Woah.

Today’s sunset. Flat out gorgeous- the whole sky was painted.

“Red Sky at night, sailor’s delight.  Red sky in the morning, sailor take warning.”

When the western sky is especially clear, there is often a red sunset. That’s because as the sun sets, its light shines through much more of the lower atmosphere, which contains dust, salt, smoke and pollution. These particles scatter away some of the shorter wavelengths of light (the violets and blues), leaving only the longer wavelengths (the oranges and reds.) If an area of high air pressure is present, the air sinks. This sinking air holds air contaminants near the earth, making the sunset even redder than usual. This would be the “red sky at night.” In the middle latitudes of the northern hemisphere, weather systems most often approach from the west. Since high pressure generally brings fair weather, this type of red sky at sunset would indicate that clear weather is approaching, which would “delight” a sailor. If the sky is red in the eastern morning sky for the same reasons as above, then the high pressure region has most likely already passed from west to the east, and an area of low pressure may follow. Low pressure usually brings clouds, rain or storms, a warning for sailors.

“Halo around the sun or moon, rain or snow soon.”

The halo around the sun or moon is a layer of cirrus clouds made of ice crystals. These ice crystals act as tiny prisms, forming a white or sometimes colorful halo around the sun or moon.  This cirro-stratus cloud often indicates an approaching warm front and an associated area of low pressure. Rain or snow will not always follow, but there is a higher probability of it after a halo is seen, and the brighter the circle, the greater the probability.

Single-cell Cumulonimbus incus - Mykonos / Greece, June 2009

A cumulonimbus incus (Latin incus, “anvil”) is a cumulonimbus cloud which has reached the level of stratospheric stability and has formed the characteristic flat, anvil-top shape. It can cause a supercell and then a tornado.

“What kind of cloud is this? A roll cloud. These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. Unlike a similar shelf cloud, a roll cloud is completely detached from their parent cumulonimbus cloud. Pictured above, a roll cloud extends far into the distance in the summer of 2005 above Albany, Missouri, USA.”

Kelvin Helmholz wave clouds.jpg

Kelvin Helmholtz instability clouds in San Francisco.These clouds, sometimes called “billow clouds,” are produced by instability, when horizontal layers of air brush by one another at different velocities. A better name might be van Gogh clouds: It is widely believed that these waves in the sky inspired the swirls in van Gogh’s masterpiece Starry Night
