Moderating Temperatures (after 6th coldest start to December since 1873)

Posted by: Paul Douglas Updated: December 17, 2013 - 8:38 AM

Low Expectations

NOAA reports 53 percent of the contiguous USA had snow on the ground as of December 15, the most in 11 years. No need to worry about a white Christmas this year.

I'm looking forward to removing a few extra layers of clothing Wednesday, as highs "surge" into the 30s. A chilly weekend gives way to another potential thaw Christmas Eve, then colder Christmas Day. A clipper dropped a little additional snow early this morning but skies have cleared, temperatures slowly falling behind this fast-moving storm.

It's human nature to wonder & worry about what comes next. "Is it going to be this miserable all winter?" Based on numerous factors, including a positive phase of the Arctic Oscillation and a brewing El Nino for 2014 I think there's a very good chance January may wind up a little milder than December.

Winter came on with a vengeance. The January Thaw will also come early, and if I had to bet I'd go with an early spring in 2014. Snowfall? Close to normal, around 55 inches.

That's based more on intuition and gut feel vs. hard science, but I do see a little relief from The Numb in coming weeks.

December is 11F colder than average; 6 subzero nights so far this month. But it's not necessarily a taste of what's to come.


First Half of December: 6th Coldest High Temperatures Since 1873. A cold start to the month? No question about that. According to the Minneapolis. “30 years at KARE and I become a Jeopardy question?

Climate Stories... Are Hurricanes Getting Stronger? Science May Finally Be Approaching An Answer. Mother Jones has a very interesting article that caught my eye - here's an excerpt: "...The result? The scientists found that globally, hurricane wind speeds are increasing at a rate of a little more than two miles per hour per decade, or just faster than six miles per hour over the entire period. There are some key caveats, though, the biggest being that the trend they found was not statistically significant at usually accepted levels. (For nerds: the p value was 0.1). But there were strong and significant trends in some hurricane basins of the world, especially the North Atlantic (the region encompassing the Caribbean, Gulf of Mexico, and open Atlantic north of the equator), where storms have been strengthening at the rate of nearly nine miles per hour per decade (see chart above). But other basins offset that, including the western North Pacific, which showed a negative trend..." Faux Pause 2: Warmest November On Record, Reports NASA, As New Studies Confirm Warming Trend. Here's an excerpt of a good explanation from ThinkProgress: " 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...” Graphic credit above: "The corrected data (bold lines) are shown compared to the uncorrected ones (thin lines)."

Whereas non-fossil fuel capacity additions totalled 31 million kW in 2012, these renewable and nuclear power stations have totalled 36 million kW so far this year – and could be projected to be 43 or 44 million kW for the whole year.

Details from NOAA's climate.gov: "The most common metric for tracking changes in Arctic sea ice over time is sea ice extent. Extent approximates the sea ice you would see from a bird's-eye view, and it has been declining at a rate of more than 14 percent per decade since satellite measurements began in 1979. If you were to descend below the sea surface, your fish's-eye view would provide an equally dramatic decline: sea ice is not only shrinking across the ocean surface, it's also thinning. Directly measuring sea ice thickness is more complicated than measuring sea ice extent, but a useful proxy for ice thickness is age. Older ice is generally thicker ice. As this pair of maps shows, the amount of very old, thick ice that exists at the end of the Arctic winter in March has dropped significantly in the past three decades.

By the middle of this century, Britain could become one of the world’s big wine producers, as global warming moves the limits of viticulture ever farther north. “The wine industry in Europe will certainly change to follow the climate changes,” said Mr. Elzinga, who is now chief winemaker at Denbies Wine Estate, one of Britain’s largest vineyards. “You can’t beat the climate, so you have to follow it...” (File: Andrea Johnson).">Twin Cities National Weather Service the first half of the month featured an average daytime high (max) of 17.2F, the 6th coldest first half of December on record. Nighttime lows averaged 5F, the 21st coldest first half of December since 1873.


From Cold Wave To Spring Fever Out East? Big changes are brewing later this week, near-record warmth surging up the East Coast while the Midwest and Great Lakes grapples with a potentially major snow storm. The pattern seems to be shifting, subtly, with a trend toward slightly milder weather for much of the USA. Winter came early, so will the January Thaw. Details in today's Climate Matters: "WeatherNationTV Chief Meteorologist Paul Douglas looks at the almost 5 FEET of snow that was dumped on upstate New York. How much snow is covering the United States? After all of the snow and cold a pattern shift is expected, but just how much?"


84-Hour Snowfall Prediction. An especially strong Alberta Clipper whips up a few inches of snow today from Pennsylvania into much of New England, maybe a couple of sloppy inches for the suburbs of New York City and Boston. 84 hour NAM snowfall prediction courtesy of NOAA and Ham Weather.


Big Swings. With these fast-moving Alberta Clippers you can see 30-35 degree temperature swings in the span of 36 hours or less. We enjoy 20s today (where else but Minnesota would you see THAT in a sentence) and 30s tomorrow before another late-week relapse. Another thaw is possible Christmas Eve, based on ECMWF data. Source: Weatherspark.


Hints of Moderation. We're due for a major shift in the pattern, and it's on the way, especially for the eastern third of the USA by late week and next weekend. The coldest subzero air (solid green line) brushes New England before lifting north into Quebec, the 32F isotherm on the move (northward for a change). 2-meter NAM predicted temperatures from NOAA and Ham Weather.


Major Sunday Snowfall Kansas City to Chicago? It's still early for specifics, but the next surge of numbing air may spin up a significant storm tracking from the Mississippi Valley into the Ohio Valley over the weekend, pulling moisture from the Gulf of Mexico into the Great Lakes, where low-level temperatures may be cold enough for heavy wet snow. Meanwhile, out ahead of the storm, a surge of southern warmth boosts the mercury into the 50s, 60s and 70s. Midday Sunday ECMWF outlook: WSI Corporation.


January Thaw Comes Early. By the weekend 70s may push as far north as Richmond, even Washington D.C., with 60s into the Delaware Valley, 50-degree highs from New York City to Boston. A far cry from heavy, wind-whipped snow. Source: Wilmington, North Carolina National Weather Service.


Pattern Shift? I want to see a few more model runs and get a better sense of whether this is a fluke or a true trend, but a positive phase of both the AO (Arctic Oscillation) and NAO (North Atlantic Oscillation) could mean more of a Pacific influence across much of the USA as we end December. We're due for a thaw. Source: NOAA.


How Do Snowflakes Form? Here's an excerpt of a detailed explanation from NOAA: "A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake. That’s the short answer. The more complex explanation is this: These ice crystals that make up snowflakes are symmetrical (or patterned) because they reflect the internal order of the crystal’s water molecules as they arrange themselves in predetermined spaces (known as “crystallization”) to form a six-sided snowflake. Ultimately, it is the temperature at which a crystal forms — and to a lesser extent the humidity of the air — that determines the basic shape of the ice crystal. Thus, we see long needle-like crystals at 23 degrees F and very flat plate-like crystals at 5 degrees F..."


Testing The Laws of Physics. It's ironic, but I've noticed a trend in recent years: SUV's are some of the first vehicles to wind up in area ditches or fender-benders when the flakes are flying. Sitting up high, and having AWD gives a (false) sense of security. Nothing is going to help if you hit a patch of black ice - the only thing you can do is slow down. Graphic: icyroadsafety.com.


Mobile Apps Will Transform All Business Processes - Is Your Company Ready? Here's a snippet of an interesting story at LinkedIn: "...So, what does all this mean for your business? It means that mobile apps designed by businesses for their internal use and competitive advantage will explode over the next two years. Therefore, all business leaders need to ask themselves: “Two years from now, do I want to be one of the companies that is not developing mobile apps to transform business processes?” Once you see the hard trends driving this software revolution, it would be hard to answer “no.” Remember, a hard trend will happen; a soft trend might happen. The hard trend is that businesses will be developing mobile apps customized for their company for various functions. The soft trend is whether your company will be one of them..."


Google Glass: Early Impressions. This is all I want for Christmas, although I'm still not exactly sure what I'd do with them, other than look even dorkier. But gizmag.com is here to help me understand why this has the potential to change my life: "Most companies conduct their experiments behind closed doors. If, say, a new iPhone hits store shelves, then chances are the dirty work has been done and it's already pretty polished.
