Record cold across Northeast US dating back to the 1800s

DREARY
Dozens - more likely hundreds - of cold records were broken or shattered on Saturday.

Many locations broke daily low temperature records, while others shattered lowest daily high temperature records.

Some of these records for lowest high temperature dated back to the 1800s.

For some reason unfathomable to me, AccuWeather forces you to muddle through several rambling unimportant paragraphs before you get to the heart of this story, which is:

Deadly spring avalanche near Jasper, Alberta - 2 killed

Outdoor enthusiasts encouraged to always be prepared after weekend avalanche kills two near Jasper.

Two people are dead after a "slab avalanche" occurred Sunday morning near Jasper, Alta, according to Parks Canada. Officials said the avalanche happened on Mount Andromeda in the Columbia Icefield, a mountain known as a popular climbing destination.

Emergency services received reports of the avalanche at around 8:30 a.m. on Sunday, and two people were found dead by the search and rescue teams that were dispatched.

Snowfall in Vermont, downpours in Boston kick off a wet Memorial Day Weekend

Snow fell on Stratton Mountain in Vermont on Saturday morning, part of a wet weekend across New England.
It was a rainy start to Memorial Day weekend in Boston on Saturday — and a snowy one in part of Vermont.

The peak of Stratton Mountain was blanketed in heavy, wet snow overnight Friday into Saturday morning, canceling gondola rides, mountain biking, and yoga sessions at the Stratton Mountain Resort.

Snowfall during the spring isn't uncommon on the mountain, but late May is unusual.

Andrew Kimiecik, a marketing communications specialist for the resort, said a small storm hit the mountain during the first week of May last year.

"One out-of-place storm in May isn't always unusual, but to see one this late in the month is a pretty uncommon occurrence," Kimiecik said.

Located in Ganzi Tibetan Autonomous Prefecture in southwest China's Sichuan Province, Zedo Mountain is an important geographical boundary with the mountainous area to its east and the eastern part of the Qinghai-Tibet Plateau to its west.

The mountain is still covered by snow in late May when most part of the country has embraced summer.

It may almost be June, but Vernon's Silver Star Mountain received a fresh dusting of snow this morning.

Webcam images from the resort show snowing falling as of 8 a.m. and the village covered in white.

The Star wrapped up for ski season over the Easter long weekend and is preparing for its summer bike park opening on June 25.

Down in the valley, today's forecast calls for mostly cloudy skies and a high of 15 C.

Sneaky late-May wet snow in Ontario catches many by surprise

Sneaky late-May wet snow in Ontario catches many by surprise

Sneaky late-May wet snow in Ontario catches many by surprise
Many in southern Ontario were caught off guard Friday morning once they awoke to a frightening scene -- wet snow, freezing rain and ice pellets.

With temperatures hovering just above the freezing mark in parts of the region, a low-pressure system that tracked south of the province Friday morning helped usher in wet snow, freezing rain, ice pellets to parts of the region. Much of the frozen precipitation is falling in higher terrains in the south.

"This pattern of a ridge to the north and low tracking to the south of the Great Lakes is your typical pattern where you can get freezing rain and ice pellets. This setup would be quite normal in the winter," said Nadine Hinds-Powell, a meteorologist at The Weather Network.

"What is unusual though is that it is this late in spring and the cold air intrusion into the moisture is this far south in Ontario."

There were reports of ice pellets and large snowflakes less than 10 km northwest of Milton, Ont., on the escarpment, with a light dusting on some surfaces.

'Mind-boggling for May': Extreme temps continues to hit Russia hard as country records 30 degrees Celsius inside Arctic Circle

A Twitter post from a British meteorologist has gone viral after he detected "mind-boggling" temperatures within the Arctic Circle in Russia, where the thermometer last week hit 30°C, hotter than almost everywhere else in Europe.

Scott Duncan, a professional meteorologist based in London who designed the popular weather-forecasting website WXCHARTS, tweeted on May 19 that such temperatures are "truly exceptional for any time of the year," but even more shocking in the month of May.

"This part of the Arctic is 20-24°C hotter than average for this time of year," Duncan said.

It was another freezing start for many in the South today, with temperatures plunging to a bone-chilling -10C in some places.

Forecaster Niwa said Middlemarch, inland from Dunedin, hit -10.1C, which was provisionally New Zealand's lowest May temperature since 2001, excluding high-elevation locations.

The wintry conditions prompted warnings for road users, with gritted roads and freezing fog reported.

Dunedin Airport was also very cold, recording -8.4C, while inland Otago was sub-zero in most places. Further north, parts of the Mackenzie Basin were also hovering around -10C.

Drama in Nepal: Escape from Everest and Baruntse because of heavy snowfall

Everest, Lhotse and Nuptse are somewhere behind these thick clouds today, May 27.
Nepal's Home Ministry has called for expedition agencies and tourism officials to make climbers return immediately from the mountains. For those high on Everest and Baruntse, returning is easier said than done.

While climbing permits are valid until the end of the month, the impact of Cyclone Yaas has prompted authorities to summon climbers down, the Everest News blog told ExplorersWeb. In fact, there may be little need for the official press release. On Everest, most teams at higher camps have switched their focus to getting down safely, in very tough conditions.

We still await news from Baruntse, where Marek Holecek and Radoslav Groh have been trapped after completing a new route. The exhausted pair, possibly without food or even fuel for melting water, are into their eighth day on the wall. Yesterday, they only managed to descend 100m. In Holecek's latest message, he said that they would attempt to descend during the night.

In the storm

Heavy snowfall will continue until Saturday. This is bad news for Holecek and Groh, as well as for those on Everest. Many climbers are weathering the storm in Camp 2 or trying to get down the mountain.

Greenland just gained a record-smashing amount of snow and ice

Greenland ice gain


According to data provided by the Danish Meteorological Institute (DMI), Greenland is currently GAINING snow and ice at a level never before seen this late into the season.


Using the daily output from a weather forecasting model combined with a model that calculates the melt of snow and ice, the DMI calculate the "surface mass budget" (SMB) of the ice sheet.

Crucial to the survival of a glacier is its SMB, which is the difference between accumulation and ablation (sublimation and melting).

The budget takes into account the balance between snow that is added to the ice sheet vs melting snow and glacier ice that runs off into the ocean.

The budget is totaled over the course of a season, from September 1 to August 31.

Last season's SMB totaled 349bn tonnes, which was "normal," according to the DMI.

Changes in this mass-balance control a glacier's long-term behavior, and are its most sensitive climate indicators.
