August snowfall in Colorado: Denver sets record low temperature

Autumn is in the air across Colorado on Wednesday as the high country received a light dusting of snow and Denver set a record low temperature.

A web cam at the Alpine Visitor Center at Rocky Mountain National Park showed the light snow dusting early Wednesday along Trail Ridge Road.

Eric Thaler, a meteorologist with the National Weather Service in Boulder, said it is likely the first measureable snow of the season in Colorado.

At Denver International Airport on Wednesday, the mercury dipped to 47 degrees, marking a record low for Aug. 19 in the Mile High City. The previous mark of 48 was set three times, in 2002, 1967 and 1960.

Denver weather forecasters call for a high of 72 degrees in Denver on Wednesday under mostly sunny skies.

"It's just going to be a nice, pleasant, Autumn-like day," Thaler said.


High temperature records 'shattered' in California

The National Weather Service says Southern California’s sharp warming trend will build into the weekend, with above-normal temperatures in many areas. Forecasters say the hottest conditions will be Friday through Sunday. Valley and desert temperatures will range from 100 to108 degrees, with highs from 85 to 95 elsewhere.
After Southern California baked under record-breaking heat Saturday, the triple-digit heat wave is expected to continue through the weekend before tapering back down toward seasonal norms during the week, according to the National Weather service.

Long Beach, Burbank and Ontario all saw records for the date, Meteorologist Joe Sirard of the NWS Oxnard office said.

"It's the usual," he said. "an upper level ridge of high pressure that built in from the east, and just brought in some hot air from over the deserts and parked it over us."

In addition, a "very shallow" marine layer rising little more than 600 feet also contributed to the Southland's sweltering temperatures, which hovered at 10 or 15 degrees above normal Saturday, Sirard said.

Burbank saw a high temperature of 104 degrees Saturday, shattering the previous record of 101 degrees set in 1977, Sirard said.

Long Beach Airport recorded a high temperature of 99 degrees, topping its 1992 record of 87 degrees, he said. And in the Los Padres National Forest, Sandberg, at more than 4,500 feet elevation, a high temperature of 99 degrees bested the previous record of 95 degrees, set in 2014.

Inland, a record of 100 degrees set in 2007 in Ontario was smashed after temperatures reached 105 degrees Saturday afternoon, NWS Meteorologist Scott Sukup said.

No summer this year in the north of Sweden

"Hösten är här - de fick ingen sommar," reads the headline. "Fall is here - they had no summer."

A few days ago, we jumped from the spring right to autumn, says this story out of Sweden.

In Tarfala in Norrbotten was never any summer this year. Two days ago there was snow on the highest peaks, says Erik Holmlund of Tarfala Research. There is more snow than it has been for a long time.

The meteorological definition of fall is that the average daily temperature should be between zero and ten degrees for five days in a row, as has happened in Tarfala and also in Stekenjokk in Västerbotten.

It is rare to places skip a season in Sweden. When that happens, it is done in the mountains, according to meteorologist Alexandra Ohlsson at SMHI.


Snowfall continues across parts of Tasmania, Australia

Snow has fallen into the afternoon in many low lying areas of Tasmania after a wintry blast saw snow fall in many parts of the state this morning.

Some Hobart suburbs received a dusting of snow this morning, and a number of schools were closed in the south-east.

The weather bureau's senior forecaster Brooke Oakley said snow was still falling at Scott's Peak in the state's south-west.

"At the moment the snow level is around 200 to 300 metres, and we have showers around the west, south and central areas and only a few light showers getting into the north-east," she said.

"Those showers are going to continue but the snow level is gradually rising to around 500 metres in the evening."


Heat wave sets historic records in Europe

Second persistent heat wave of the summer season has set more temperature records in parts of Europe, during last week. Poland, Germany, Italy, Czech Republic, Belarus and Lithuania reported new all-time records, while the hot conditions are forecasted to last across most of the eastern Europe until early next week.

High temperatures in Poland caused the national power suppliers to cut off the electricity to factories for a few days on August 10, as the period of extended heat caused the water levels to drop, in rivers used to cool the power plants.
A historic record was set in Wroclaw, Poland on August 8 when temperatures hit 38.9 ºC (102 ºF), weather records researcher Maximiliano Herrera reported. Usually, temperatures average 23 ºC (74 ºF) this time of year in Wroclaw.

Old Farmer's Almanac predicts super-cold winter, snow for much U.S.

Just when you thought you had gotten over last winter, be warned: The Old Farmer's Almanac predicts it will be super cold with a slew of snow for much of the country, even in places that don't usually see too much of it, like the Pacific Northwest.

If you don't want to read about those four-letter words, there's plenty more to peruse in the folksy, annual book of household tips, trends, recipes and articles, such as animal jealousy, the history of shoes and anticipation for the biggest Supermoon in decades in November 2016.

Otherwise, look for above-normal snow and below-normal temperatures for much of New England; icy conditions in parts of the South; and frigid weather in the Midwest. The snowiest periods in the Pacific Northwest will be in mid-December, early to mid-January and mid- to late February, the almanac predicts.

"Just about everybody who gets snow will have a White Christmas in one capacity or another," editor Janice Stillman said from Dublin, New Hampshire, where the almanac is compiled. It's due out in the coming week.

The almanac says there will be above normal-rainfall in the first half of the winter in California, but then that will dry up and the drought is expected to continue. "We don't expect a whole lot of relief," Stillman said.

The weather predictions are based on a secret formula that founder Robert B. Thomas designed using solar cycles, climatology and meteorology. Forecasts emphasize how much temperature and precipitation will deviate from 30-year averages compiled by government agencies.

Largest amount of snow in 20 years lingers on the Cairngorms, Scotland

These striking pictures were captured by Helen Rennie at Ciste Mhearad in the northern Cairngorms.

Low summer temperatures mean snow continues to cling to the mountainsides of the Scottish National Park, even in the middle of August. But as the patches begin to melt from below, and water flows downhill, vast caverns - some big enough to walk through - are formed.

Snow thaw on farms delayed by freezing temperatures around Canterbury, New Zealand

Sheep in snow
A blanket of snow is refusing to budge along the Canterbury foothills as Mt Somers farmers deal with freezing temperatures and a colder than average winter.

In the second decent dump of the winter farmers in the district were still foot slogging through snow persisting because of temperatures continuing to reach minus six to seven degrees Celsius.

Rangiatea run farmer Blair Gallagher was shearing on Sunday night when the first snow of eventually "seven inches" - about 170 millimetres - landed and was backed up by another smaller drop of 50mm to 70mm. By yesterday there was still 100mm to 120mm on the ground.

During an earlier June snow the temperature gauge dropped to minus 10deg.

The latest snowfall arrived on Sunday followed by another top-up over the last week.


Here it comes: Heavy snowfall expected in Brooks Range, Alaska

Anaktuvuk Pass, Brooks Range
The Brooks Range is expected to get significant snowfall today, with as much as 5 inches forecast in some areas by Tuesday morning.

Rainfall is expected to change to snow in elevations higher than 3,000 feet in the northeastern Brooks Range, which includes Anaktuvuk Pass, Atigun Pass, Galbraith Lake, Sagwon and Franklin Bluffs.

The National Weather Service warns that people in the backcountry should be prepared for difficult travel through wet snow today and Tuesday. Motorists on the Dalton Highway are also warned to be prepared for snowy conditions on Atigun Pass.
