Frozen Jingle Bells
The snow-globe vision outside my window is right out of a Norman Rockwell painting. So why does I-394 merging into I-94 in Minneapolis look like the trailer for a Steven King horror flick? Simple. It's too cold for MnDOT chemicals to work effectively. Black ice is a much bigger threat at 5-10F than it is at 20-25F
We're studying the economic feasibility of a retractable dome over the MSP metro area; until then all we can do is slow down - and leave more time to get around town.
I'm forecasting the whitest Christmas since we woke up to a whopping 19 inches of snow on December 25, 2010. If you're keeping score: 5 Christmases since 2001 have had an inch of snow or less.
When it's this cold air puffs up between snowflakes, like feathers in a down comforter. Easy to get off your sidewalk, but prone to being compressed by traffic into glaze ice.
Today will bring our your inner survivalist: single digit "highs", a chill factor near -15F. Double digit negative numbers early tomorrow, then a period of snow Christmas Eve. Expect 2-3 inches, heavier amounts east of St. Paul, maybe 4-6" for Wisconsin.
People keep asking me when we'll pull out of this Deep Freeze. That's an easy one.

"The atmosphere and oceans are storing the energy of 4 Hiroshima bombs every second, 400,000 every day."
“… equivalent to exploding 400,000 Hiroshima atomic bombs per day, 365 days per year. That’s how much extra energy Earth is gaining each day.”That comes out to more than four Hiroshima bombs a second, which is a metric Skeptical Science has turned into a widget. I prefer the 400,000 Hiroshimas per day metric simply because the heat imbalance is occurring over a very large area, which four Hiroshimas don’t do justice to. The deniers don’t like the metaphor because, they assert, it is inexact and sensationalistic. But the deniers don’t like the literal facts because they think those are inexact and sensationalistic, too, so we can safely ignore them..."
