"Despite the usual exhortations by those forecasters pushing the numerous predictive "indices", we are not headed for another ice age in the U.S. next month. NO numerical model shows a high-latitude blocking signal, so any cold that does make its way through the lower 48 states will likely be of the "quick hit" variety." - meteorologist Larry Cosgrove.

"A Class 3 warning means that a storm is so powerful that it can be dangerous to be outside." - from a Swedish web site warning of yet another severe winter storm.
East Coast Soaker. Yes, that's a 5.8" bullseye north of Atlanta. Five day rainfall amounts will top 1-3", with the heaviest amounts from the Appalachians westward to Detroit, Indianapolis and Louisville.
Predicted Snowfall Through Midnight Wednesday Night. Enough cold air may filter into the east coast storm for a few inches of accumulation from near Flint and Ann Arbor, Michigan southward to South Bend, even Indianapolis. NAM data courtesy of NOAA NCEP and WeatherCaster.
* GFS 500 mb forecast map above is valid December 13. It shows a trough of low pressure over the nation's midsection capable of spinning up a storm for the Mississippi River Valley and Great Lakes. There's still no evidence of a full-latitude blocking pattern capable of funneling consistently bitter air south from the Arctic Circle or Alaska. The coldest, Siberian air is being shunted well north - no evidence of any subzero air making a pass at the lower 48 through mid December.
Fernando The Frog Says Slow Down! Always good advice, but especially so for motorists in California's Central Valley. Long nights and lingering moisture have combined to produce thick, zero-visibility "tule fog", so dense it often doesn't dissipate by afternoon.

Global Weirding Whacks Your Wallet. Some interesting statistics from njtoday.net: "Commodities worldwide are also taking a hit. Peanut butter prices, for example, soared this autumn after searing summer temperatures scorched the U.S. peanut crop – pushing bulk prices from $450 to $1150 a ton. That means at least a thirty percent price hike for Smucker’s Jiff and Unilever’s Skippy. Then there’s U.S. beef devastated by the Texas drought. Ranchers are slaughtering starving herds rather than take a total loss. While this has created a brief beef glut with lower prices, expect the long-term loss of herds to bring higher costs for hamburger next year, and for t-bones and roasts in 2013, says American Public Media’s Marketplace. Many global crops grow best within strict limits of temperature, rainfall and altitude. Half the world’s chocolate, for example, is made from Ghana and Ivory Coast cocoa grown only between 72 and 77 degrees Fahrenheit, at an altitude of 330 to 820 feet. Hotter weather is forcing cocoa higher – above 1,500 feet in the next forty years. Costs to the industry and chocolate lovers will make the climb along with the crop."
