Northern Tier Snow Chances With Storms In Florida – December 20, 2021 Weather Outlook

National Weather Forecast

Looking at the Monday before Christmas across the lower 48, a system off the west coast will bring rain and snow chances to portions of the Northwest south into the Bay Area. A low that’ll be working from the Northern Rockies to the upper Midwest by Tuesday will bring snow chances spreading east across the Northern Plains. A frontal system could bring portions of New England snow, and a system across the Southeast will bring shower and storm chances.

The heaviest snow will be across portions of the Northern Rockies and Cascades where at least a foot or two of snow could fall. The heaviest rain will be across portions of Oregon with at least three inches possible in some areas. However, at least 1-2” of rain could also fall across the Southeast.

Climate change is shrinking the odds of a white Christmas, this year included

More from the Capital Weather Gang: “The unforgettable lyric to Irving Berlin’s classic holiday song may need a rewrite: “I’m dreaming of a warm Christmas, unlike the ones I used to know” … Exceptionally mild weather dominating the Lower 48 this month shows little sign of meaningful change through the Christmas holiday. This means rather underwhelming chances for a white Christmas in many parts of the United States, a state of affairs to which we probably should become accustomed. Our warming climate appears to be eating away at white Christmas chances, newly available data shows.”

The “Doomsday Glacier” may partially collapse. If it does, Earth’s sea level will rise by 2 feet

More from Salon: “The widest glacier on the planet — nicknamed the “Doomsday Glacier” because its collapse could trigger a chain of events resulting in millions of people being permanently flooded out of their homes and becoming climate refugees — is showing signs of collapse. It’s called the Thwaites Glacier, and it is the size of Florida. And what happens to it in the next few years could radically alter the future of human (and Earth) history. Located in western Antarctica, Thwaites Glacier currently empties 50 billion tons of ice into the ocean every year. As a result, the glacier is already responsible for roughly four percent of the planet’s annual sea level rise. That’s because when it warms enough to belch ice into the water, that ice slowly melts, causing the overall volume of water in the ocean to increase.”

Midwest lags, though Madison and Minneapolis shine in national clean energy policy ranking

More from Energy News Network: “Madison, Wisconsin’s clean transportation investments helped propel it ahead in an annual ranking of clean energy and energy efficiency plans. The analysis of 100 major cities by the American Council for an Energy-Efficient Economy (ACEEE) revealed that nationwide, cities are largely not on track to meet their own greenhouse gas reduction goals, and/or they don’t collect data that would allow them to meaningful log such emissions reductions. ACEEE rated cities on building sustainability, renewable energy, transportation, government initiatives and community impact. Overall, Midwestern cities lagged behind the coasts, with only three cities in the region ranking in the top 20: Minneapolis at 4th, Chicago at 12th, and St. Paul at 20th. Madison, at 39th, was the most improved city nationwide, while Milwaukee dropped significantly from last year’s report to 53rd.”
