Extreme Temperatures
A whopping 438" of snow fell in Valdez last season. That's 36 feet of total snow accumulation! The 2011-2012 season delivered over 100" above the average (326").
In fact, after a whopping 98" of snow fell just in the first 12 days of January 2012, the National Guard had to be called in to help rescue folks buried in both Valdez and nearby, Cordova, AK. Incredibly, snow invaded a home of one unlucky Valdez resident.
Here's the kicker. Yesterday's first measurable snow in Valdez occurred 17 days earlier than last season. Of course, there's no predictive value to this, much as an early start to the hurricane season doesn't usually say much about the rest of the season.
The weekend cold snap is just about over. Low temps this morning in the 30s will be replaced with highs in the upper 60s this afternoon along with sunshine and south winds. Temps Tuesday will move into the mid or upper 70s along with gusty south winds, but a cold front will pass the area late Tuesday evening bringing highs back down into the upper 60s to near 70 Wednesday afternoon.
The Bureau of Meteorology said many areas could see snow, frost and hail as the result of a low pressure system moving across NSW. "We've had quite a few reports of snow. We're expecting snow down to 700m over many parts of the state," said meteorologist Julie Evans. There has been 2.5cm of snow on the ground reported at Nerriga, in the southern tablelands. In the Blue Mountains, snow has been falling between Blackheath and Katoomba.
The Bureau of Meteorology says snow falls have occurred right along the Great Dividing Range and as far north as Queensland's Granite Belt.
At its height, snowfalls of 15 centimetres and wind damage cut roads and rail access to the upper Blue Mountains for more than six hours.
In the Blue Mountains, 300 cars were stranded by the mountain road closures.
But the SES's Jennifer Finlay says most of the 550 calls for help came from further to the south.
"The Illawarra south coast got hit pretty hard with lots of trees down a bit of roof damage, fortunately nothing too severe," she said.
Endeavour Energy reconnected more than 2,000 properties to power on Friday afternoon, but hundreds of outlying properties between Mount Victoria and Medlow Bath and in the Megalong Valley will not get power back until Saturday.
With temperatures predicted to get down to 3 degrees Celsius overnight, the company has urged people in areas where the power is out to check on neighbours who live alone.

September 26, 2012, when ice covered more of the Southern Ocean than at any other time in the satellite record.
An unusually cold storm in southern Australia has dished out the first October snow in a century.
Snow whitened the ground along the Mount Lofty and southern Flinders ranges, east and north of Adelaide, South Australia, the Australian ABC News website said.
Images published Thursday on the ABC website showed snow-covered ground at Hallett, in an upland valley north of Adelaide. Posted videos showed falling snow in the hills east of Adelaide.
At low elevations, rain fell late Wednesday to early Thursday at temperatures in the lower to middle 40s, weather data available to AccuWeather.com showed.
Normal low temperature in Adelaide is about 50 degrees, whereas the typical high is in the lower 70s.
Up to three-quarters of an inch of rain is expected in some areas, with the possibility of tornadoes.
Forecasters said snow levels could drop to as low as 7,500 feet on Friday. The Kaibab Plateau, San Francisco Peaks and the White Mountains could see between one inch and three inches of snow.
These snow amounts appear to be record amounts for this early in the season for many areas. The previous record snowfall for October 4 or earlier at the NWS in Grand Forks was 2 inches on October 2, 1950. The NWS at Grand Forks reported 3.5 inches of snow with this storm on October 4, 2012. While records from around the area indicate that the October 2, 1950 storm produced about 2-5 inches around the region with localized higher amounts, with Leeds, ND receiving 7.0 inches on October 2, 1950, and Hallock 4.5 inches.
They have found that one of the "engines" driving the Gulf Stream - the sinking of supercooled water in the Greenland Sea - has weakened to less than a quarter of its former strength.
The weakening, apparently caused by global warming, could herald big changes in the current over the next few years or decades.
Paradoxically, it could lead to Britain and northwestern and Europe undergoing a sharp drop in temperatures.
Such a change has long been predicted by scientists but the new research is among the first to show clear experimental evidence of the phenomenon.
Peter Wadhams, professor of ocean physics at Cambridge University, hitched rides under the Arctic ice cap in Royal Navy submarines and used ships to take measurements across the Greenland Sea.
Comment: Note, this was seven years ago. Since then, Arctic and Green land ice sheet melt has been increasing, with the Greenland sheet melt in 2012 setting an all-time record. Recent winters in the UK and Northern Europe have made it rather clear that we are facing a much colder Northern Hemisphere, which carries the possibility of a new mini, or full scale, ice age. One year soon, winter will arrive but spring and summer may not.
Comment: Note how the meteorologist claims "it's not unprecedented" because there were similar conditions in 2008. Well that's alright then! Nothing to worry about!
