Crippling Ground Blizzard By Late Week?
By Paul Douglas
All I want for Christmas is the ability to get out of my driveway. That may be asking a lot, based on what I'm seeing: a plowable to crippling snowfall, followed by ground-blizzards by Friday.
Siberian air will flood the USA east of the Rockies - arctic chill as far south as the Gulf Coast and Florida. An intense storm winding up over the Great Lakes will pump Gulf moisture into Minnesota, obviously cold enough for all-snow, a dangerous "cold storm". An intense pressure gradient will whip up 40-50 mph gusts by Friday, turning new powder into near-blizzard conditions and white-outs from the Upper Midwest into the Ohio Valley. Temperatures will be near 0F by day with a chill factor ranging from -25 to -40F. Extra-dangerous if you get stuck.
Models suggest 5-10" of new powder by the end of this week. If you're trying to find the best window for travel I suggest today or Wednesday AM. Travel by land and air will be treacherous from Thursday into Christmas Eve. The Christmas Blizzard of 2022? Sounds about right.

"An Unmistakable Stain in America's Most Pristine Rivers"
"Dozens of once crystal-clear streams and rivers in Arctic Alaska are now running bright orange and cloudy—and in some cases, they may be becoming more acidic. This otherwise-undeveloped landscape now looks as if an industrial mine has been in operation there for decades, and scientists want to know why. Roman Dial, a professor of biology and mathematics at Alaska Pacific University, first noticed the starkest water-quality changes while doing field work in the Brooks Range in 2020. He spent a month there with a team of six graduate students, and they could not find adequate drinking water. "There's so many streams that are not just stained; they're so acidic that they curdle your powdered milk," he says. In other streams, the water was clear, "but you couldn't drink it [because] it had a really weird mineral taste and tang."
"People are loving this simple hack to stop you slipping on icy pavements"
"The UK is currently experiencing the big freeze, with snow and ice weather warnings continuing across the UK after the record for the coldest night of the year so far was broken for the second night in a row. Brrrrr. With temperatures plummeting and snow and ice falling across many areas of the UK, slipping on an icy pavement is a very real risk right now. While some people are trying to avoid skidding over by trying to stick to paths and roads that are gritted, one woman has come up with a simple yet clever hack for avoiding falling over in the wintry conditions. With driveways and paths turning into hazards, TikTok user @mels_family_life has shared trick to increase your grip on the ice and help prevent you toppling over."
"A derecho swept through the Midwest a year ago. Now there are efforts to better define the storms"
"It was an unusually warm day in mid-December. "Everybody commented that it was just kind of spooky," said Matt Thompson, who co-owns Lost Grove Ag Services, a seed and fertilizer application business near Harcourt, Iowa. "You don't see that on December 15." Thompson heard reports that it was going to storm, so he made sure all machinery at the business was put away. By 6 p.m., he said, tornado sirens were going off and wind was coming through. By the time the sun came up the next day, five of the businesses' six buildings were gone. "We didn't know what we were going to do," Thompson said. "It was pretty devastating to see. It was unbelievable. I'll never forget that."
