Massive Snow Melt This Week
Hard to believe that it was about a week ago that parts of the Twin Cities metro picked up more than 1 foot of snow. Some of the heaviest amounts reached 20" near St. Paul! 2 to 3 days later, most of the snow had all but melted thanks to record high temperatures and heavy rain on Wednesday.
Unique Storm of December 15, 2021:
"The storm system that crossed over Nebraska, Iowa, Minnesota, Wisconsin and Illinois over December 15-16 was almost totally unique in many of its atmospheric attributes. Hundreds of temperature and dew point records were set with the rapid transport of heat and moisture from the south. The wind structure of the atmospheric layers supported record-setting wind speeds, as well as producing 25 reports of tornadoes (12 in NE, 13 in IA), and three suspected reports of tornadoes in MN, yet to be verified. Though fast moving, the storm system produced some record-setting rainfall amounts as well. Among the most rare and unique measurements of the storm were: confirmed tornadoes on the ground near Lewiston (Winona County) and Hartland (Freeborn County), the first ever observed such storms in Minnesota during the month of December; a radiosonde (balloon) measured precipitable water measurement from the Twin Cities (integrated water vapor content in the atmosphere overhead) of 1.23inches, the highest measurement ever made in Minnesota during the months of December, January, and February; a dew point measurement at MSP airport of 55°F, the highest historical dew point measurement historical for the Twin Cities between December 6th and March 6th; a maximum temperature reading of 66°F at Caledonia, Winona, and Austin, all-time statewide record high for this time of year, and about 30-35 degrees F above normal."

A Barely-White Christmas for the Metro?
By Paul Douglas
All I want for Christmas is my two front teeth...more snow...no winter tornadoes or Polar Vortexes... and fewer references to the Greek alphabet in 2022 would be nice, Santa.
We will tell our grandkids about 2020 and 2021, even though they'll think we're telling tall tales. Weather is always fickle and extreme, but 2021 took it to an absurd new level: the biggest severe storm outbreak of the year happened on December 15, not May. Drought drained lake water levels, smoke from western fires made it hard to breathe at times during the hottest summer on record in the US. Pond-hockey-worthy ice came a month later than usual this year.
Parts of the north metro are waking up to an inch of fluff this morning. Models predict a few minor snowfalls next week, mainly northern counties, with a few days in the 30s. A couple inches of new snow may fall on central Minnesota, with some 4-8" amounts over the northern third of the state by Christmas.
ECMWF predicts a few rain showers in the metro on December 25. Insulting.

Moon Phase for December 18th at Midnight
0.1 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."

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."
