December 12, 1995: A low pressure system moved across northern Minnesota depositing a band of five to seven inch snowfall along a line from around Wheaton, to north of St. Cloud, to around Rush City. Alexandria received seven inches of snow. Meanwhile in southern Minnesota, one to four inches of snow fell, along with one-quarter to one-half inch of freezing rain, which forced some school closures.
December 12, 1821: Cold snap begins at Ft. Snelling. Below zero for 19 days except one.
Fog, Smog & Drizzle
Minnesota's weather is about as interesting as a test pattern. Remember those? I'm dating myself. The Doppler is temporarily unplugged; I've hacked the weather computer to play endless games of Madden NFL 15.
This is what an El Nino winter looks like: gray, damp, but above zero most of the time. Boring has never looked so good, here in a land where 40F can earn a weather guy a high-five.
Yesterday it was above 60F some 4,000 feet above the Dakotas. A stubborn inversion has put a lid on the atmosphere: warm air aloft, chilly air at ground-level; no churning and overturning of the air. The result: fog and a mid-winter smog, as particulate pollution becomes trapped near the surface. A little light rain and drizzle is likely today and Sunday as temperatures poke into the 40s; more typical of early March.
El Nino winters tend to be milder and drier for Minnesota, as the biggest storms track from California to Texas, then right up the East Coast. Our models hint at a mix ending as a couple inches of snow Monday before cooling off next week. Nothing frigid brewing looking out 2 weeks.
Will the coolest year since 1996 include a white Christmas?
It'll be a close call.

- As the world heats up and more heat is carried in the atmosphere as water vapor, heavy precipitation events are becoming more intense.
- Climate models project that atmospheric river storms in California will become more frequent and intense in the future, which means it is likely that the current storm is a taste of what’s to come..."

A new study estimates nearly 270,000 tons of plastic is floating in the world's oceans. That's enough to fill more than 38,500 garbage trucks if each truck carries 7 tons of plastic. The figure appears in a study published, Wednesday, Dec. 10, 2014, in the scientific journal PLOS ONE. Researchers say the plastic is broken up into more than 5 trillion pieces."
