November 21 in Minnesota Weather History:
1996: Heavy snowfall accumulated over the same areas that were hit two days earlier. Four to seven inches of snowfall were reported across the area. Heavier snowfall occurred during the daylight hours of the 23rd. Snowfall totals of six inches were reported in the Twin Cities, Chanhassen, Stewart, St. James and Redwood Falls.
1970: Gale driven snow across Minnesota. 45 mph winds over Rochester and Duluth.
Life is random; our future ultimately unknowable. Maybe that's why we take some small comfort in the weather forecast. It's one of the few things we can anticipate with any level of skill.
Perfect? Not by a long shot. The 24-hour forecast accuracy, nationwide, is 88 percent. It's human nature to remember the 12 percent of the time we blow it. Day 3-7 accuracy is improving about 1 percent every year, and new technology has made "surprise" tornadoes, floods & blizzards more unlikely.
Predicting the future is hard. Ask any stock broker or economist. How's your fantasy football team doing? Welcome to my world.
NOAA is predicting a slight cool bias for the Red River Valley into February; no clear trend toward wetter or drier weather for the Upper Midwest. The 90-day outlook is interesting to ponder, but confidence levels are very low, especially this winter. I still think we'll wind up slightly milder; an earlier spring in 2014 than we had this year.
Expect colder than average temperatures into Thanksgiving week but no major storms close to home. A soaking rain may slow things down out east Tuesday & Wednesday; long-range guidance now hinting at a warming trend by the first week of December.

Unavoidable Answer For The Problem Of Climate Change. Here's a clip from a story at The New York Times: "...It brings into sharp focus the most urgent challenge: How will the world replace fossil fuels? Can it be done fast enough, cheaply enough and on a sufficient scale without nuclear energy? For all the optimism about the prospects of wind, sun and tides to power our future, the evidence suggests the answer is no. Scrambling to find an alternative fuel to generate some 30 percent of its power, Japan had no choice but to turn to coal and gas..."

In 2011, coal was used to generate 30.3 percent of the world’s primary energy, the highest level since 1969, according to the World Coal Association, an industry trade group. That share slipped only to 29.9 percent last year." Photographer: Dadang Tri/Bloomberg.
