1993: The Thanksgiving Day Blizzard of 1993. Central and Western to South Central Minnesota were affected by a slow moving storm system that traveled across the upper midwest during the Thanksgiving holiday causing heavy snow across most of Minnesota. Travel became extremely difficult if not impossible over west central Minnesota where over a foot of snow accumulated. A number of car accidents were reported and several community events were canceled. Snowfall in excess of six inchs or greater occurred north of a line from Bricelyn (Faribault County) to the Twin Cities. Counties affected by this storm include Anoka, Benton, Blue Earth, Brown, Chippewa, Chisago, Douglas, Faribault, Hennepin, Isanti, Kanabec, Kandiyohi, Lac Qui Parle, Martin, Mcleod, Meeker, Mille Lacs, Morrison, Nicollet, Pine, Pope, Ramsey, Redwood, Renville, Rock, Sherburne, Sibley, Stearns, Stevens, Swift, Todd, Washington, Watonwan, Wright, and Yellow Medicine.
1983: Snowstorm dumps almost two feet at Babbitt and about 20 inches at Duluth.
1825: Warm spell begins over Ft. Snelling, Temperature rises up to 70 degrees over the week.
There are few other places on the planet where locals “thank” a meteorologist for 50 degrees. It’s been too cold, too early. “Paul, if it’s like this in November, what will January be like?” Cold, with some snow. Just a gut feeling.
If it was a sticky 85 degrees year-round I’d have motion sickness from swaying in a hammock, lost in a Corona-coma. I’d get nothing done.
Bracing slaps of wind chill focus our ingenuity, forcing us to engineer new ways to keep out the pain. We survive. We thrive. And no Minnesotan I’ve ever met takes a warm front for granted.
Here’s what I know: the next 2 weeks won’t be as cold as the previous 2 weeks. A coating of snow is possible today as winds blow from Canada; another inch or two of slush Wednesday. The pattern isn’t ripe for headline-grabbing snow storms thru the second week of December.
I see a subtle shift in the pattern, possibly a symptom of a brewing El Nino. Rain is finally reaching California, and a slightly milder, zonal, Pacific wind flow will thaw us out from time to time, as early as next weekend.
Climate volatility is real; the swings are getting more severe. Buffalo’s suburbs go from 8 feet of snow to 60F and flooding today.
An Early Nap? Thanksgiving is Thursday (as if you could possibly forget that fact) and after gazing at the maps I’m already getting a little sleepy. No major storms are brewing this week, maybe a coating to an inch today (more over Wisconsin), another inch or two Wednesday, possibly some accumulation by Tuesday of next week. Thursday appears to be the coldest day in sight with highs holding in the teens, but European data is hinting at another thaw next weekend.
60-Hour Snowfall Potential. NOAA NAM data shows some 8-15″ amounts just downwind of Lake Superior into early Wednesday, but plowable amounts of snow are possible from near Rhinelander and Green Bay to Oshkosh. If your travels take you east snow amounts will gradually increase as you approach Lake Michigan. Source: HAMweather.
Close Call. A storm winding up over the Great Lakes will inhale enough Canadian air to change rain over to snow across Wisconsin and the U.P. of Michigan. More snow accumulates from near Denver to Boise; a series of Pacific storm delivering some badly needed rain to drought-stricken California this week. It looks like the El Nino signal is finally kicking in, pushing the storm track farther south over the western USA.
December Temperature Spike? I’m not buying it, not yet, but the GEFS model is hinting at 50F in the Twin Cities on December 3. It’s still a long way out; 40s seem more plausible in early December as Pacific air pushes east of the Rockies. Not sure about 50F, but we are due for the weather pendulum to swing in the other direction. Chart: Aeris Enterprise from HAMweather.
Winter Weather Weirdness May Be Just Beginning. The Buffalo News, where they know a thing or two about odd weather, has the story – here’s an excerpt: “…Meteorologists and geographers say that lake-effect snows have increased as temperatures have warmed in recent decades. That means more bizarre early-season storms, though not necessarily as bad as last week’s, are likely in the future as the warming trend continues. “The general notion is that, as the climate warms and the lakes hold their warmth longer into the fall, you’re going to see a lot more lake-effect snow until it’s too warm to have much snow,” said Mark Monmonier, distinguished professor of geography at Syracuse University and the author of the 2012 book “Lake Effect: Tales of Large Lakes, Arctic Winds, and Recurrent Snows…”

Snowed Under and Frozen Over: U.S. Weather Is Off The Rails, But Why? The jet stream is “drunk” once again – memories of last winter have emerged much sooner than anyone wanted or expected. Will it continue, and how is a rapidly warming Arctic impacting prevailing steering winds? Here’s an excerpt of an explanation at Capital Weather Gang: “…Last summer we saw the 6th lowest sea-ice minimum extent, and the extremely warm temperatures now over the Arctic are from all the extra heat absorbed by the Arctic Ocean where ice was lost,” Francis said. “When the Arctic is so warm, the west winds of the jet stream weaken, and this favors the highly wavy pattern to the jet stream responsible for this early winter chill in the eastern U.S as well as the continued drought and heat in California.…”
TODAY: Gusty winds, turning colder. Coating of light snow. Winds: NW 15-30. High: 25

Expect More Giant Snowstorms As Climate Warms. A warmer atmosphere contains more water vapor, loading the dice in favor of not only heavier summer rains, but more extreme winter snows – until temperatures become too warm for snow. LiveScience has the story; here’s an excerpt of the article, including a quote from Penn State climate scientist Michael Mann: “…Part of what gave us the record lake-effect snowfall in Buffalo was warm, late-fall lake-surface temperatures that combined with something highly unusual: a 5 sigma event. That is, a very unlikely event on the order of 1-in-a-million — a remarkably persistent, anomalous configuration of the jet stream, which brought frigid Arctic air down into the United States so early in the season,” said Michael Mann, professor and director of the Earth System Science Center at Pennsylvania State University. “The cold winds traveling over the warm moisture-laden lake created a perfect storm of conditions for record lake-effect snow…”
Global Warming: Extreme Weather Will Be The “New Climate Normal”, World Bank Warns. International Business Times has the article – here are a few clips that got my attention: “The World Bank Sunday warned extreme weather will become the “new climate normal,” increasing the risk of world instability. The report, “Turn Down the Heat: Confronting the New Climate Normal,” analyzes the impact of warming of 2 to 4 degrees Celsius (3.6 and 7.2 degrees Fahrenheit) above pre-industrial levels on crops and coastlines….Extreme heat is the biggest problem, the report found, because it can reduce crop yields, negatively impacting food security and future economic growth as well as economic development, social stability and well-being…”

New Study: Major Investors Worried About Companies’ Readiness for Climate Change. Wall Street, increasingly, is paying attention. Liability is growing – companies realize they have risk. The smart ones will ignore science deniers and take steps to lower long term threats to their business models (and share price). Here’s the intro to a story at Forbes: “A new study from a significant source shows that a majority of large investors are worried about companies’ readiness for climate change. The source is significant in that this information isn’t just the data, say, of a fringe environmental group – it’s asset managers and pension fund managers responsible for a total of more than $11 trillion...”

Half of Americans Think Climate Change is a Sign Of The Apocalypse. The Atlantic has the article – here’s an excerpt: “Snowmageddon, snowpocalypse, snowzilla, just snow. Superstorm Sandy, receding shorelines, and more. Hurricanes Isaac, Ivan, and Irene, with cousins Rammasun, Bopha, and Haiyan. The parade of geological changes and extreme weather events around the world since 2011 has been stunning. Perhaps that’s part of why, as the Public Religion Research Institute reported on Friday, “The number of Americans who believe that natural disasters are evidence of the apocalypse has increased somewhat over the past couple years…”
