1996: An ice storm moved through much of central and southern Minnesota and west central Wisconsin. Schools closed or began late over much of southern Minnesota the morning of the 15th due to a 1/2 inch thick layer of ice that covered much of the area. Flights were canceled at Minneapolis/St. Paul International Airport due to ice forming on airplanes and runways, however mainly sleet was reported in the Twin Cities.

A Murky Crystal Ball
The WMO, The World Meteorological Organization, reports that 2013 is on track to be the 7th warmest on record, worldwide.
That's all well and good, but winter in Minnesota has not been cancelled. Not by a long shot. "If it ever gets to the point where it doesn't snow AT ALL in Minnesota we'll have much bigger problems on our hands" a climate scientist told me recently.
My wife asked me when we had snow on the ground last year. Good question. Less than an inch of snow fell during November, 2012. December made up for the slow start with a whopping 15 inches; 10.5 inches falling on December 9, 2012.
I still don't see any (Breaking News!) snow events looking out 2 weeks or so. Rain is likely Saturday, a brief break Sunday before a second storm arrives with more rain ; ending as snow Sunday night. A slushy half inch or so is possible, but this does not look like The Big One.
We chill down early next week, although it doesn't look as cold as it did a few days ago. I see more 40s from late next week into the days preceding Thanksgiving; a slight mild (Pacific) bias. Our (very) experimental 45-day trend doesn't show snow on the ground until Christmas.
That's more of a wish-cast than a forecast though.
A D.C. Detour
"Man plans. God laughs." Yep. Life rarely goes where you think it will go.
On Tuesday I met with EPA Administrator Gina McCarthy, discussing stewardship and creation care issues; climate change as a spiritual as well as moral and scientific challenge. At the White House I talked about communicating the science, and our efforts to launch companies focused on adapting to a more volatile world of weather extremes.
NOAA does a great job helping consumers deal with acts of God. But acts of man, including carbon pollution? Coming soon: a new national database showing impacts down to your zip code; how changes in weather patterns are already affecting your hometown - and what the LONG range forecast may bring. Because climate change doesn't hit home until it (literally) hits home.
November 21 To 27 Temperature Anomalies. NOAA's NAEFS extended model shows a mild bias from eastern Minnesota into much of northern and eastern Canada, temperatures across most of America close to average for mid/late November.
Why Was Typhoon Haiyan/Yolanda So Powerful, And Is This A Trend? Climate scientist Greg Laden takes a look at scienceblogs.com; here's an excerpt: "...But here I want to look at one single factor that almost certainly contributed to the growth of Haiyan/Yolanda into a very powerful storm, a factor that probably doesn’t usually play into a storm’s strength. I refer to an anomaly in sea surface temperatures that was almost certainly caused by global warming, as part of a general warming of the ocean. But first a bit of background on the link between sea surface temperature and hurricanes. This is one of several factors that may be involved in climate change related effects on tropical storm intensity, a situation with which we should be concerned. Tropical cyclones run on heat, and much of that heat comes from the sea surface..."

NASA Study May Help Predict Major West Coast Snow Falls. Climatescience.com has an interesting story - here's the intro: "Atmospheric rivers - short-lived wind tunnels that carry water vapor from tropical oceans to mid-latitude land areas - are prolific producers of rain and snow on California's Sierra Nevada mountains. The finding, published in the journal Water Resources Research, has major implications for water management in the West, where Sierra runoff is used for drinking water, agriculture and hydropower. The research team studied how two of the most common atmospheric circulation patterns in the Northern Hemisphere interact with atmospheric rivers. They found when those patterns line up in a certain way, they create a virtual freeway that leads the moisture-laden winds straight to the Sierras..."

AIRS is one of six instruments on board the Aqua satellite, part of the NASA Earth Observing System. AIRS along with its partner microwave instrument, Advanced Microwave Sounding Unit (AMSU-A), represents the most advanced atmospheric sounding system ever deployed in space. Together these instruments observe the global water and energy cycles, climate variation and trends, and the response of the climate system to increased greenhouse gases."

While short term trends are generally treated with a suitable level of caution by specialists in the field, they feature significantly in the public discourse on climate change.There’s another aspect to this, though, and it may be a bigger deal than might at first be apparent. It adds up to a pretty scary situation. That’s because the “slowdown” or “hiatus” has also had a number of alternative explanations. Decreased solar activity. Increased volcanic activity. A prevalence of cool-phase El Nino oscillations. Increase in aerosol loading from rapid and dirty Chinese industrial expansion. Heat export to deeper ocean layers..."

Peru Uses Climate Twist To Lure Tourists To Shrinking Glacier. Here's an excerpt of a story from Reuters: "In its heyday, the Pastoruri glacier in central Peru, drew daily throngs of tourists packed into dozens of double-decker buses 16,000-feet (5,0000-meters) high into the Andes to ski, build snowmen and scale its dizzying peaks. It was so bright with ice and snow that sunglasses were mandatory. But in less than 20 years, including at least 10 of the hottest on record, Pastoruri has shrunk in half, and now spans just a third of a square mile (0.9 square km)..."
