How Friday night’s rare and deadly December tornado outbreak unfolded

More from The Washington Post: “A devastating outbreak of tornadoes that swept through parts of the Midwest and Tennessee River Valley on Friday night is poised to become the worst on record to strike the United States during December. Kentucky Gov. Andy Beshear (D) said he expects the death toll in his state alone to reach at least 70 to 100. If that is the case, it will become the deadliest December tornado outbreak on record and among the 15 deadliest in any month. “Last night was one of the most shocking weather events in my 40 years as a meteorologist — a violent tornado (in December!) drawing comparisons to the deadliest and longest-tracking tornado in U.S. history,” tweeted Jeff Masters, a meteorologist and expert on extreme weather.”

Study Shows Critical Need to Reduce Use of Road Salt in Winter, Suggests Best Practices

More from The University of Toledo: “Across the U.S., road crews dump around 25 million metric tons of sodium chloride — much like table salt — to unfreeze roads each year and make them safe for travel. Usage varies by state, but the amount of salt applied to icy roads annually in some regions can vary between approximately 3 and 18 pounds of salt per square meter, which is only about the size of a small kitchen table. As the use of deicing salts has tripled over the past 45 years, salt concentrations are increasing dramatically in streams, rivers, lakes and other sources of freshwater.”

Fleeing Global Warming? ‘Climate Havens’ Aren’t Ready Yet

More from Grist: “Forget the palm trees and warm ocean breeze. The upper Midwest could soon be the most sought-after living destination in the United States. The curb appeal of the Great Lakes region is that it appears to be a relatively safe place to ride out the wild weather of the future. It’s far from the storm-battered Eastern seaboard and buffered from the West’s wildfires and drought, with some of the largest sources of fresh water in the world. The Great Lakes help temper the bitter winds of winter and cool the muggy summer. And rising temperatures are beginning to take some of the bite off that winter weather: Michigan, in fact, is turning into wine country, with vineyards growing warm-weather grapes like pinot noir and cabernet sauvignon.”
