Great Lakes Ice Cover at Highest Levels in 20 Years

This week's intense Arctic cold blast has brought the highest ice coverage on the Great Lakes in twenty years, according to data from the Canadian Ice Service. Ice coverage over Lakes Superior, Michigan, Huron, Erie, and Ontario increased from 12% to 26% over the past week, reaching levels not seen at this time of year since the last Great Lakes cold blast of this intensity, in January 1994. Most notably, Lake Erie is now more than 90% frozen over. This will spell a temproary end to intense lake effect snowstorms for areas downwind of the lake like Buffalo, New York, since Arctic winds blowing over the lake will no longer be able to pull moisture from open water to fuel heavy snows. Buffalo received more than a foot of snow from Tuesday and Wednesday's lake effect blizzard, which tapered off because the lake froze up so significantly. With Saturday temperatures over southern Great Lakes expected to warm to the mid-40s, accompanied by rain, ice formation on the Great Lakes will slow down this weekend, but ice coverage should still be above normal for the remainder of January.

Increased ice cover will keep Great Lakes water levels higher
The increased ice coverage on the Great Lakes this winter is good news for water levels on the lakes, which are still struggling to recover from some record lows recorded at this time last year. During January 2013, water levels on Lake Michigan and Lake Huron fell to their all-time lowest values since record keeping began in 1918, 29 inches below the long-term average. While the water levels recovered substantially during 2013, which was one of the wettest years in Michigan's history, water levels were still a foot below average at the beginning of 2014. The above average ice cover this winter will reduce evaporation from the Great Lakes, keeping water loss lower than in recent winters. Ice cover on the Great Lakes has declined 71% since 1973, according to a 2012 study published in the Journal of Climate by researchers at NOAA's Great Lakes Environmental Research Laboratory. The loss of ice is due to warming of the lake waters, which could be due to a combination of global warming and natural cycles, the researchers said. Winter air temperatures over the lower Great Lakes increased by about 2.7°F (1.5°C) from 1973 - 2010, and by 4 - 5°F (2.3 - 2.7°C) over the northern Lakes, including Lake Superior. Lake Superior's summer surface water temperature warmed 4.5°F (2.5°C) over the period 1979 - 2006 (Austin and Colman 2007). During the same period, Lake Michigan warmed by about 3.3°F (1.7°C), Lake Huron by 4.3°F (2.4°C), and Lake Erie (which is shallow and loses and gains heat relatively quickly) showed almost no warming.

The long-term future of Great Lakes water levels is cloudy, since climate change is expected to bring competing effects. A 2011 paper by scientists at NOAA Great Lakes Environmental Research Laboratory found that lake levels could rise or fall, depending upon the climate change scenario used. On the one hand, precipitation has increased by 12% over Michigan during the past century, and is expected to increase even more in the coming decades. This would tend to increase lake levels. However, lake water temperatures are predicted to increase and ice cover decrease, which would heighten evaporation rates. This would tend to lower lake levels. The Army Corps of Engineers is considering adding speed bumps to the bottom of the St. Clair River to slow down drainage of Lake Huron, which would act to increase water levels in Lake Huron and Lake Michigan.

The 12z ECMWF was impressive for eastern North Carolina. A cut-off low develops offshore from a longwave trough over the central United States, bringing snow to the region. Several runs have shown the same. The CMC isn't as bullish, but shows a snow flurry or two.

NWS maintains sunny skies and highs in the upper 40s. We'll see.



TA..if you still here..how much snow for us?

2014 will be a year of the unexpected, when a hose unkinks it does so quickly. The jet stream will be a major player in the spring, most likely bringing a robust severe weather season. And if cold winters are any harbinger, based on past hurricane seasons after severe cold snaps; 2014 will bring many majors to the Atlantic basin. Like winters are bipolar now for Europe and the US, the hurricane season will be too. Like playing craps at the casino, pick a number and guess,and you'll be as right as any "expert" on the number of TS and Canes for next season. Anyone seen Sar around lately?

49.6 degrees (121 F) - Australia's highest temperature in 15 years
Brett Dutschke, Sunday January 13, 2013 - 17:02 EDT

Yesterday (Saturday) Moomba in the far northeast of South Australia recorded a maximum temperature of 49.6 degrees, which makes it the highest temperature recorded in Australia in 15 years.

The last time a higher temperature was recorded was in February 1998, in the Western Australian Pilbara, where Nyang reached 49.8 degrees.

Moomba's 49.6 degrees is also the highest temperature recorded in SA since Oodnadatta reached 50.3 degrees 53 years ago, in January 1960.

Australia's record is held by Oodnadatta, 50.7 degrees, also in January 1960.

Yesterday a wide area surrounding Moomba was also very hot, reaching the high 40s. In far western Queensland Birdsville got to 48.6 degrees, its hottest day in 22 years. In northwestern New South Wales yesterday Wanaaring reached 48.6 degrees, equalling White Cliffs' 48.6 in 1973 as the hottest it has been in NSW in 106 years. In January 1906 Bourke reached 48.9 degrees.

Since this current heatwave began at about New Year, the location which has the hottest week has been Oodnadatta in SA. Oodnadatta averaged a maximum of 46.5 degrees from January 2nd to

Scientists have located the coldest place on Earth, and while it may not be a surprise that it's in Antarctica, the record-setting chill is enough to make the hardiest souls shudder.

The mercury dipped to minus 135.8 degrees Fahrenheit on a high ridge in the Antarctic mountains, a team of researchers announced this week.

That's cold enough to freeze carbon-dioxide gas into a solid -- dry ice -- and turn gasoline into a thick slushie. And that temperature was 40 degrees colder than the record low for a permanently inhabited place –- set in two villages in Russia's Siberia region in 1892 and 1933, according to NASA.

The record-setting measurement was achieved thanks to the most detailed temperature map ever of the Earth's surface, scientists said Monday at a conference in San Francisco.

The record is "tens of degrees colder than anything ever seen in Alaska, Siberia or Greenland," said Ted Scambos, the lead scientist at the National Snow and Ice Data Center in Boulder, Colo., who was behind the discovery.

That's cold enough to freeze carbon-dioxide gas into a solid -- dry ice -- and turn gasoline into a thick slushie. And that temperature was 40 degrees colder than the record low for a permanently inhabited place –- set in two villages in Russia's Siberia region in 1892 and 1933, according to NASA.

The record-setting measurement was achieved thanks to the most detailed temperature map ever of the Earth's surface, scientists said Monday at a conference in San Francisco.

The record is "tens of degrees colder than anything ever seen in Alaska, Siberia or Greenland," said Ted Scambos, the lead scientist at the National Snow and Ice Data Center in Boulder, Colo., who was behind the discovery.
