Dwindling Odds of White Christmas Much of USA

Dwindling Odds of White Christmas Much of USA
By Paul Douglas
I'm dreaming of a white (tornado-free) Christmas. Once again a lousy inch of snow in the Twin Cities on December 25 may come right down to the wire.
We shouldn't be too surprised. According to an analysis by AP, during the 1980s 47% of the US had snow on the ground December 25, with an average snow cover of 3.5". By the 2010s that number had dropped to 38% of the US. Capital Weather Gang says "our warming climate appears to be eating away at white Christmas chances". Latest 30 year climate data shows the trends, which according to NOAA "are consistent with the reality of long-term warming." Statistically, the odds of a white Christmas have held steady in the Twin Cities (roughly 3 out of 4 are white).
The northern half of Minnesota may pick up another 2-5" by Christmas, but this week looks relatively mild, with daytime highs mostly in the 30s. ECMWF predicts 40F and rain showers on Christmas Eve. Santa may need to load up toys in his red SUV Friday. Models hint at snow in 8 days - and teens by late month.

Moon Phase for December 19th at Midnight
1.1 Days After Full "Cold" Moon
"10:37 p.m. CST - December is usually considered the month that the winter cold begins to fasten its grip in the Northern Hemisphere. This month's full moon is also called the Long Night Moon, since nights are at their longest and darkest. It's also known as the Moon before Yule. The term Long Night Moon is a doubly appropriate name because the midwinter night is indeed long and the moon is above the horizon a long time. The midwinter full moon takes a high trajectory across the sky because it is opposite to the low sun. This is also the smallest full moon of 2021 (a "micromoon," or minimoon), since the Earth will arrive at apogee, its farthest distance from Earth, on Dec. 17 at a distance of 252,476 miles (406,320 km). The moon will appear some 14% smaller compared to the full moon of May 26."
National High Temps Sunday
The weather outlook on Sunday shows above average temperatures continuing across the Southeast, where record highs will be possible across parts of Florida. Meanwhile, cooler than average temps will be found in the Southern US and also in the Western US.
National Weather Outlook
The weather outlook through early next week shows lingering showers and thunderstorms across the Southeast and the Gulf Coast, where locally heavy rains will be found. There will also be some wintry precipitation across the Northeast on Sunday with minor snow accumulations. Note the heavy precipitation ongoing in the Northwest, where a large storm system will continue to bring waves of heavy Pacific moisture to the Western US through the Christmas weekend. Areas of heavy mountain snow and flooding rains will be possible.
Extended Precipitation Outlook
According to NOAA's Weather Prediction Center, areas of heavy precipitation will be found along the West Coast over the next several days with localized flooding. There will also be several feet of snow in the high elevations. There will also be another surge of heavy precipitation across parts of the Gulf Coast States and the Southeast.
Extended Snowfall Potential
Here's the extended snowfall potential through Christmas, which show heavy snow potential across the Western US. There will also be another swath of heavy snow along the International Border and into the Northeast.
Climate Stories
"2021 was a remarkable year for Earth's climate"
"The close of another year provides an opportunity to assess what happened in the worlds of climate science and policy in 2021 and to gaze into a proverbial crystal ball to anticipate likely events in 2022. This was a year full of climate-fueled extreme weather events, the publication of important new climate research and synthesis reports, and a crucial international climate negotiation. It ends with anticipation and uncertainty over whether the U.S. Congress will pass the country's first-ever major climate change legislation. 2021 certainly did not lack for important climate events. A hot year full of extreme weather When the year comes to a close, 2021 will be the sixth- or seventh-hottest year on record and hotter than any year prior to 2015, despite a La Niña event's having drawn cold water to the surface of the Pacific Ocean. La Niña years tend to be cooler than years with El Niño or neutral conditions in the Pacific. The year 2000 saw a La Niña event of similar strength to that in 2021, but 2021 was more than 0.4 degrees Celsius (0.75 degrees Fahrenheit) hotter than 2000. In short, 2021 was consistent with the long-term human-caused global warming trend of about 0.2°C (0.36°F) per decade."
"THESE...ARE CHEMICALS OF HIGH GLOBAL CONCERN."
"IT'S A PERFECTLY pleasant day for a stroll on the beach. The Sun shines overhead while wet sand clings to your bare feet. As you turn to face the ocean, a gust of sea breeze blows through your hair, giving it a classic windswept look. And transports toxic chemicals into your body to linger there long after you towel off. Sounds idyllic. WHAT'S NEW — A study published Wednesday in the journal Environmental Science & Technology finds that sea spray can transport chemicals, known as PFAAs, into your body via airborne particles. These chemicals are of "high global concern" to humans. The findings have serious implications for understanding how these toxic chemicals make their way into the atmosphere and affect human health, especially for coastal communities. "PFOS, PFOA, and many other PFAAs are highly enriched on sea spray aerosol and can be transported back to the atmosphere from the oceans," the paper's authors tell Inverse in a joint interview. Co-authors Bo Sha, Ian Cousins, and Matthew E. Salter are researchers in Stockholm University's Department of Environmental Science."
"All Weather Records Broken in 2021: Temperatures, Rain and Snowfall"
"Over the past year, the U.S. saw a wide array of severe weather events, and several weather records, such as rainfall amounts, high and low temperatures and snowfall accumulation, were broken. In Oregon during the past summer, record-high temperatures were recorded in Seattle and Portland. In June, the National Weather Service in Seattle reported two consecutive days of record-high temperatures. On June 28, the NWS recorded a temperature of 108, which was the highest number ever recorded in the city, surpassing the 107 degrees recorded the day before. On the same day, the NWS in Portland recorded a record-high temperature of 116 degrees, surpassing a previous record of 112 recorded just a few days before."
