Extreme Temperatures
The cold wave, which reaches South, Southeast, Midwest, and up to two northern states of the country (Rondônia and Acre), is the longest in 13 years, according to the National Institute of Meteorology (Inmet).
"Should greatly disrupt agriculture"
"There were 17 days in all. Now, there are already seven days with temperatures below zero, and certainly this will continue until Friday, which should greatly disrupt agriculture, especially citrus plantations and lettuce, and bring problems health," says meteorologist Lucia Gularte of Inmet.
Among the places hit by the snow are two capitals: Curitiba and Florianópolis. In Curitiba, the record snow made on Tuesday by Simepar Meteorological Institute is the first since 1975.
Santiago and other cities were affected by record low temperatures during the past few days, with some areas reaching as low as 16.8 F (-8.4 C) Monday.
The south central area of Chile faced the coldest temperatures of the year on Monday with below-freezing temperatures expected to continue until Tuesday, according to the Chilean Meteorological Office (DMC).
Chilean students received a cold welcome back from their winter vacation as Santiago's lowest temperature of the year came in at 26.6 F (-3 C) in Quinta Normal at 6:56 a.m. Monday morning. Santiago saw a high of 55.4 F (13 C). Just outside of the capital, Lampa claimed the country's record low temperature of the year with shivering lows of 16.8 F (-8.4 C). Calera de Tango in the Valparaíso Region clocked in with a low of 25.5 F (-3.6 C).

Mendoza province experienced heavy snowfall as a consequence of the intense cold.
In Catamarca province, a 51-year-old man died of a heart attack caused by hypothermia, in his Altos de Choya home. In the Parque Norte Oeste district of Catamarca, meanwhile, a 19-year-old disabled youth also lost his life.
In the early hours of Monday morning Jose Romera, a homeless man aged 47, was discovered in the streets of Andresito, Misiones, and was pronounced dead also due to hypothermia.
In Salta, meanwhile, a three-year-old boy was killed by carbon monoxide poisoning, a consequence of fumes from a heater which had been turned on to combat the intense cold.
Early morning temperatures in Buenos Aires dropped as low as 1.6°C, before rising to 10° in the afternoon. Similar numbers are forecast for Wednesday, before the rest of the week sees a slight increase in temperature.
In parts of Jujuy and Mendoza provinces, meanwhile, locals suffered with temperatures of up to -10°C.
NOAA (the National Oceanic and Atmosphere) describes the cold wave that will reach the Southern Cone of America and Rio Grande do Sul as "extraordinary."
MetSul Meteorology analysis says that the wave will bring polar temperature to atypical locations as far north as northern Bolivia and southern Peru as well as the Midwest of Brazil, Sao Paulo, Rio de Janeiro and Minas Gerais.
According to NOAA, the flow of moisture from the sea will bring snow to coastal areas of Patagonia to southern Brazil, including the province of Buenos Aires and also in Uruguay.
The report adds that heavy snow will hit much of Patagonia, reaching Viedma and Bahia Blanca with accumulated 10-15 centimeters. Should snowing, says NOAA, mostly in the province of Buenos Aires. In the area of ​​the River Plate and the southeastern Uruguay can be expected bumps of snow and snow mixed with rain (water nieve).
An information bulletin issued by the Prince George Fire Centre on Friday, July 12 stated the inclement weather had allowed the Wildfire Management Branch of the Ministry of Forests, Lands and Natural Resource Operations (FLNRO) to wrap up their response to several of the wildfires in the region, reducing the number of active fires in the Prince George Fire Centre to just four.
Last week saw 16 new, small wildfires in the region, but the Fire Centre noted they didn't pose any risk to structures.
Just one of those fires was the result of human activities.
"We have had 123 fires and burned 2,136 hectares so far this year," said Dustin Eno, a fire information officer with the Prince George Fire Centre.
The majority of that activity has been in the Fort Nelson Zone.
"Last year at this time we had had 137 fires and burned 7,467 hectares," he added.
When sunspot activity is high, as it was during the 1990s and early 2000s, temperatures tend to be high as well. When it is low, as it is now, temperatures fall. And because sunspot activity occurs in decades-long cycles, the unusually cold winter and spring of 2012 may be just the beginning. As a Barron's article recently noted, current sunspot activity is now the least it has been in a century.
What this means is that the era of global cooling has begun. In the northern hemisphere, three out of the four last winters and springs have been unusually cold. This spring was so cold in East Asia that China was forced to import millions of tons of grain and soybeans from the U.S. and other suppliers.
Dr. Kate Barlow, Head of Monitoring at the Bat Conservation Trust, said, "After 2 years of long, wet, winters and a particularly late and cold start to summer this year, the outlook isn't too promising for our bats. The most recent results from the National Bat Monitoring Programme showed that there were fewer bats were counted in 2012 than in 2011 for most species monitored."
Dr. Barlow added that 2013 saw the coldest March in 50 years and summer got off to such a late start many of the species are struggling. "This year Britain's bats need all the help they get," she said.
Further adding to the bat recovery struggle is the fact that winged insect numbers are also down. So on top of a cold spring and delayed summer, several species may face shortages in food supply, especially those that rely on moths, according to a National Trust report released last month.
Santa Rosa, N.M. - In some areas of New Mexico Wednesday, it looked more like the night before Christmas than Independence Day Eve.
More than a foot of hail covered streets, yards and parking lots in Santa Rosa, about 100 miles east of Albuquerque. A huge thunderstorm dumped golfball-sized hail around 6 p.m.
Snow plows cleared drifting hail from the roads.
The storm caused severe damage to many homes, cars and businesses.
Meteorologists say large accumulations of hail are fairly common in northeast New Mexico because of the high elevation.

In the trenches: The British couple had to call the tow truck before they could continue their holiday. - They are not so used to driving on this road conditions, says Morten Hansen from Traffic surveillance. There have been no reports of other accidents associated with snowfall.
- They had not driven more than 400 meters before they ended up in the ditch, says Kari Varberg (50), who owns and operates Dyranut Fjellstov
She sat at the breakfast table when it started snowing on Saturday morning.
Shortly after, she was called upon to take care of the two British campers who ended up in the ditch.
- They had woken up and seen that it was snowing, so they wanted to get out quickly on the fells, she says.
Las Vegas - A high pressure system hanging over the West this weekend is expected to bring temperatures extreme even in a region used to baking during the summer.
Notoriously hot Death Valley's forecast could touch 129 degrees, not far off the world-record high of 134 logged there July 10, 1913. The National Weather Service called for 118 in Phoenix, and 117 in Las Vegas on Sunday - a mark reached only twice in Sin City.
"It's brutal out there," said Leslie Carmine, spokeswoman for Catholic Charities, which runs a daytime shelter in Las Vegas to draw homeless people out of the dangerous heat and equip them with sunscreen and bottled water.
While the Southwest boasts the most shocking temperatures, the heat wave is driving up the mercury all over the West. Western Washington - better known for rainy coffee shop weather - should break the 90s early next week, according to the weather service.
Dry southern Utah is forecast to reach higher than 110 degrees, and northern Utah - which markets "the greatest snow on Earth" - is also expected to see triple digits.
The heat wave is "a huge one," National Weather Service specialist Stuart Seto said. "We haven't seen one like this for several years, probably the mid- to late 2000s."
