'So You're Telling Me There's a Chance?' Numbing Christmas may follow a few inches of snow

We May Get That White Christmas After All

Turns out Mother Nature is a bit of a drama queen. After teasing winter weather lovers with the snowiest Minnesota October on record, winter has been playing hard to get in recent weeks. My puke-colored lawn is mocking me now.

It'll come down to the wire, but don't write off a white Christmas yet. After a few more relatively mild days jet stream-steering winds buckle by the middle of next week, spinning up a fast-moving storm capable of a few inches of wintry fun late Tuesday into midday Wednesday. It's too early for specifics, but yes, a few inches of powder may fall.

Which brings up a meteorological axiom: Fresh bursts of numbing air are (usually) preceded by accumulating snow. Not always, but most of the time.

One thing is quite certain: Your jingle bells may freeze solid by late next week. ECMWF predicts a metro high of -3F Christmas Eve. NOAA's GFS model says 4 above. All or nothing.

A thaw is likely after Christmas and most climate models show a mild signal much of January. We shall see.

First Arctic Front of the Winter. Subzero temperatures are likely late next week, just in time for Christmas, and I could see chill factors dipping to -30F for about 36 hours before a rapid warming trend the weekend after Christmas. Just a subtle yet blunt reminder that it's December.

Golden Snow Shovel Award. Take a bow Newark Valley, New York. 44" of snow from a single storm is the definition of impressive. For updated snow totals click here.

Snowstorm Rages in New England After Burying Parts of New York With More Than 40 Inches. Capital Weather Gang has a few jaw-dropping details: "An early winter wallop of snow, sleet and ice slammed parts of the Mid-Atlantic and Northeast on Wednesday and Thursday, bringing accumulations exceeding 40 inches in spots and a slick glaze of ice for some. Strong shoreline winds and coastal flooding accompanied the system, contributing to near-blizzard conditions as the intensifying strip of low pressure swept northeast. Sixty million Americans were placed under advisories, watches or warnings in advance of the storm, which was continuing to pivot into northern New England early Thursday afternoon. One snowfall jackpot as of sunrise Thursday was near the National Weather Service office in Binghamton, N.Y., where a staggering 39.6 inches had fallen by 7 a.m. It observed an astonishing 20.5 inches in six hours..."

Growing Drought. Exceptional drought is being reported across much of the southwestern USA, with pockets of moderate drought showing up over Minnesota's Red River Valley and far west central counties. Click here for more details from the U.S. Drought Monitor.

Relatively Mild Into Tuesday, Then Turning Much Colder. We may hit 40F Sunday and again Monday before a temperature slide next week, accelerating after a potential snow event next Wednesday.

A Brief, Concentrated Shot of Arctic Goodness. We go off a temperature cliff the middle of next week with daytime highs struggling to reach zero or low single digits Christmas Eve. Only a couple days of shuddering and shivering; NOAA's GFS model shows a fairly robust warming the last week of December.

Seeing the Covid-19 Pandemic from Space. NASA imagery is tracking changes brought on by the virus; here's an excerpt: "Economic and social shutdowns in response to the COVID-19 pandemic have led to noticeable changes in Earth's environment, at least for the short term. NASA researchers are using satellite and ground-based observations to track these impacts on our air, land, water, and climate. These datasets have been collected in a free and openly available online dashboard. The NASA COVID-19 Dashboard features data collected by Earth-observing satellites, instruments aboard the International Space Station, and sensitive ground-based networks..."

How Buying Stuff Drives Climate Change. Especially over the holidays, as Columbia University's State of the Planet explains: "Did you know that Americans produce 25 percent more waste than usual between Thanksgiving and New Year's Day, sending an additional one million tons a week to landfills? This COVID-19 holiday season, with online shopping the preferred gift giving method for many, we will likely generate even more waste mailing packages all over the country. In addition, over two billion Christmas cards are mailed every year, with enough paper to fill a football field 10 stories high. More than 38,000 miles of ribbon are thrown away and usually end up in landfills. Over the holidays, Americans discard half their total yearly paper waste, mostly holiday wrapping and decorations—about nine billion tons. And each person wastes almost 100 pounds of food..."

Minnesota Power Reaches 50% Renewable Energy. Cost (for renewables) are falling and the tide is turning.
