Minnesota Weather History on December 17. Data source: Twin Cities National Weather Service:
1922: Heat wave across southern Minnesota. Temperatures rose into the 60's at New Ulm and St. Peter.
1917: Milaca had its fifty-ninth consecutive day with no precipitation.
For the first time in over 2 weeks the mercury will rise above freezing today. Prepare to be serenaded by the soothing sounds of dripping icicles and gurgling drain-spouts. Happy noises.
NOAA reports the first half of December saw the 4th coldest daytime highs and 21st coldest nighttime lows in the Twin Cities since 1873. Nothing like easing into winter.
A puff of Pacific air treats us to mid-30s today. More waves of Canadian air slosh south, chilling us back down through the weekend - but not as Nanook as the first week of December.
As long as steering winds are howling from the west-northwest Minnesota's weather will be dominated by a family of Alberta Clippers; each one preceded by a brief warm-up, followed by cold winds and flurries. These fickle low pressure swirls moving in from Edmonton move quickly; starved for moisture, unable to tap a deep, rich layer of water vapor in the Gulf of Mexico.
One such storm may dump significant snow this weekend from Kansas City to Chicago. On the warm side of the storm highs surge into the 70s on the east coast - 60s into Washington D.C. and Philadelphia. Talk about weather-whiplash!
The January Thaw may come early this year.

Don't skimp. About 25% of flood insurance claims come from outside high-risk areas. If you live near any body of water, consider buying a policy through the National Flood Insurance Program (few private carriers offer policies). Even melted snow can cause flooding.
Brace for price shock. FEMA is phasing out subsidies for pre-1970s homes, raising rates roughly 25% a year..."

In a second study reported in the same , Ranney and his colleagues presented college students with a somewhat longer version of this explanation (a full 400 words), and found that doing so not only increased students' understanding of global warming, but also their acceptance that it's actually occurring..."Earth transforms sunlight's visible light energy into infrared light energy, which leaves Earth slowly because it is absorbed by greenhouse gases. When people produce greenhouse gases, energy leaves Earth even more slowly – raising Earth's temperature.

The Global Temperature Jigsaw. More on the alleged temperature "pause" from RealClimate: "...First an important point: the global temperature trend over only 15 years is neither robust nor predictive of longer-term climate trends. I’ve repeated this now for six years in various articles, as this is often misunderstood. The IPCC has again made this clear (Summary for Policy Makers p. 3):
Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends.You can see this for yourself by comparing the trend from mid-1997 to the trend from 1999 : the latter is more than twice as large: 0.07 instead of 0.03 degrees per decade (HadCRUT4 data)..."

A new study by British and Canadian researchers shows that the global temperature rise of the past 15 years has been greatly underestimated. The reason is the data gaps in the weather station network, especially in the Arctic. If you fill these data gaps using satellite measurements, the warming trend is more than doubled in the widely used HadCRUT4 data, and the much-discussed “warming pause” has virtually disappeared.“There are no permanent weather stations in the Arctic Ocean, the place on Earth that has been warming fastest,” as New Scientist explained five years ago. “The UK’s Hadley Centre record simply excludes this area, whereas the NASA version assumes its surface temperature is the same as that of the nearest land-based stations...”
