Coldest Weather/Freezing Weather ....Warming is Cooling

3rd January:
Winter storm Eleanor has swept into most of northern Europe, including France and Germany after battering the UK,

6th January
North America's East Coast is shivering in a record-breaking freeze in the wake of a deadly "bomb cyclone" that dumped snow as far south as Florida. On Wednesday 3rd Jan, snow fell in Tallahassee, Florida, for the first time in more than 30 years, causing travel chaos in the region. Five inches of snow fell in Charleston, South Carolina, making it the third snowiest day since the city began keeping records in 1938. 
On Friday 5th, the National Weather Service (NWS) predicted dangerously low temperatures moving into the weekend as frigid air lingering over the North Pole prowls towards the US mid-Atlantic region. "An arctic outbreak will keep temperatures 20F to 30F degrees below average across the north-eastern US," the NWS said. In Massachusetts, residents of Boston, which received over 30 cm of snowfall, were clearing the streets with shovels. 
Around a quarter of Americans across the Midwest and parts of the Southeast were under winter weather advisories today.

At least 39 record low temperatures were set on Sunday 7th morning across the eastern US, said CNN meteorologist Pedram Javaheri.
The temperature at JFK airport dropped to 5F (-15C) Sunday morning, breaking the previous record of 6F (-14.4C) set just three years ago. (Do we detect a trend here?)
Meanwhile, an ice storm dumped freezing rain from the Missouri Valley through the Ohio and Tennessee valleys into parts of the Mid-Atlantic and the Northeast.

Several daily record low temperatures were broken or tied in at least seven states in the Northeast today (January 7), including.
Baltimore, Maryland (BWI airport): 1 degree (-17.2C)
Boston, Massachusetts: minus 2 degrees (tie) (-18.9C)
Burlington, Vermont: minus 20 degrees (-28.9C)
Hartford, Connecticut: minus 9 degrees (-22.8C)
Philadelphia, Pennsylvania: 4 degrees (tie) (-15.6C)
Providence, Rhode Isalnd: minus 3 degrees (-19.4C)
Richmond, Virginia: minus 3 degrees (-19.4C)
Worcester, Massachusetts: minus 9 degrees (-22.8C)

Hudson river freezes as US hit by record-breaking lows of -40C, reads headline.”
Arctic conditions in areas including Philadelphia, Boston and New York.”
Ice 12 inches (30 cm) thick in places after 2 days of record cold.

Interesting Comparison of great lakes ice coverage on Jan 6 over past few years.

“I assume this page will update with more recent data,” says reader Greg C. “But today ( Jan 6, 2018 ) it shows percent coverage ( rounded ):

2018 – 30%
2017  – 9%
2016 – 2%

“But, then again, we were told that AGW causes Global COOLING."

In Canada, the provinces of New Brunswick and Newfoundland and Labrador are both under winter storm and blizzard warnings. On Friday morning, Nova Scotia Power said some 125,000 customers were still without power after 140 km/h wind gusts hit parts of the maritime province. Ontario is under an extreme cold warning, while Quebec faces heavy snowfall, strong winds and storm surges. Boston harbour's tide gauge matched its record at 15.1ft - previously set during the great blizzard of 1978. The weather pattern has already brought snow to the US South as far down as Florida, where the cold snap has caused iguanas to lose their grip and fall from trees. 

7th January
The Australian city of Sydney has experienced its hottest weather in 79 years with temperatures in the region hitting as high as 47.3C in Penrith, west of Sydney. Severe fire warnings were issued for the greater Sydney area and total fire bans were put in place across the city. Sunday's temperatures fell short of the scorching heat to hit the area in 1939, when the mercury reached 47.8C.

8 Jan 2018 – 
Parts of Sahara Desert covered in 15 inches of SNOW
More than 15 inches (40cm) blanketed sand dunes across the small town of Ain Sefra, Algeria.
It is the second time snow has hit in nearly 40 years, with a dusting also recorded in December 2016.
But yesterday’s snowfall is much deeper than last year’s fleeting flurries, which brought chaos across the town, with passengers stranded on buses after the roads became slippery and icy.
Before that, Ain Sefra last saw snow on February 18, 1979. That snow storm lasted just half an hour.
"And snow was supposed to be a thing of the past in high latitudes?"

Bangladesh Cold: The lowest temperature of the day, 5.8C in Chuadanga and Rajshahi districts."8 January Chittagong second city of Bangladesh recorded 6.3C, its lowest T ever.Previous was 7.2C in 1937 and 1964."...Max Informs.

9th January
Unusually heavy snowfall has trapped around 13,000 tourists at the Swiss resort of Zermatt, one of the country’s most popular ski stations.
Switzerland’s WSL Institute for Snow and Avalanche Research said Monday afternoon that at least 80 cm (31.5 inches) of snow had fallen on the Zermatt area over the last 24 hours, raising the avalanche risk to a maximum level.
French forecasters have described the snowfall as the kind only seen “once in every 30 years.”

A number of other Valais villages were also isolated by heavy snow, including the Simplon region of Valais,  which was hit by two metres ( Equivalent to 200 mms of rain) of snow in a 24-hour period, (more than 6 ft), the ATS news agency reported. We’ll hear more about it when it finally melts and causes flooding!

Continuation of previous post on U.S....Some technical details..

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of the frozen Northeast landscape on December 28, 2017. Brisk northwesterly winds created rows of “cloud streets” as cold air blew over Lake Ontario and the Atlantic Ocean. A layer of snow covered much of New England and upstate New York.
Cloud streets are long parallel bands of cumulus clouds that form when cold air blows over warmer waters and a warmer air layer (temperature inversion) rests over the top of both. The comparatively warm water gives up heat and moisture to the cold air above, and columns of heated air called thermals naturally rise through the atmosphere. The temperature inversion acts like a lid. When the rising thermals hit it, they roll over and loop back on themselves, creating parallel cylinders of rotating air. As this happens, the moisture cools and condenses into flat-bottomed, fluffy-topped cumulus clouds that line up parallel to the direction of the prevailing winds.
While the cold streak has not broken all-time records, it is breaking records for individual days. On the day the image was acquired, weather observers on Mount Washington (New Hampshire) recorded a daily record low of -34 degrees Fahrenheit (-36° Celsius). Baltimore, Boston, Flint, New York, Montreal, and Toronto Cities have seen records fall during this cold snap.
The cold weather pattern has its origins in a large bulge, or ridge, in the jet stream that has brought unseasonably warm weather to Alaska. On the east side of this ridge, a trough in the jet stream plunged southward, bringing plenty of Arctic air with it. This orientation of the jet stream, which looks similar to the greek letter omega, is known as an omega block.(See Article on 200 Jet Streams..Explained there).
