Missoulians awoke to snapped tree limbs, smothered shrubs and intermittent power outages on Wednesday as a slow-grinding snowstorm delivered as forecast.

Utility vehicles were scrambling up Rattlesnake Drive, where dozens of branches were down across power and communications wires.

For fallen trees and limbs that are not blocking a street or threatening power lines, Missoula residents can call the City Park Operations Office at 552-6253. Those with fallen tree limbs blocking travel can call the City Forester at 552-6270 to get a crew out as soon as possible.

National Weather Service volunteer observers reported 5 inches of snow in many places around Missoula.

Grouse Mountain in British Columbia receives 25-cm (9 inches) dump of May snow

Monday night's heavy snowfall was good news for skiers and snowboarders in the Vancouver area but for not so much for drivers on mountain highways in the B.C. Interior.

Grouse Mountain saw a total of 25 centimetres of fresh snow skiers. Cypress Mountain and Mount Seymour both remain closed for the season.

Meanwhile, snowfall is forecasted to continue in the Interior, and Environment Canada has sent out a warning to motorists to expect winter conditions between Hope and Kamloops, as well as along the Okanagan Connector from Merritt to Kelowna. Conditions are expected to get worse later in the day.

Fresh May snowfall in the Cascades, Washington

cam shot
As this seems to be the winter that never ends, the Cascades are once again under winter weather headlines. A Winter Weather Advisory is in effect for the Washington Cascades until this evening, with accumulating snow as low as Snoqualmie Pass.

An unusually strong low-pressure system for this time of year is currently moving through the region. This movement brings colder temperatures into the mid-levels of the atmosphere. As the temperatures aloft fall, so does the snow level.

This morning, the snow level had fallen to around 3,000 feet. While it's not unusual to see May snow in the Cascades, it is somewhat rare to see accumulating snow this low this late in the year. If you're traveling over the mountain passes today, plan on encountering some slushy snowfall on the range of 1-4 inches. Above 4,500 feet, the totals will be closer to 6-12 inches.

Dragon ice traps crab fishermen's boats in warming Arctic Oceans

trapped in ice
Dragon ice is a form of ice pancakes stacking on top of each other during prolonged gale force wind events. This was captured by research scientists from New Zealand on an expedition to Antarctica. Crab fishermen are asking for compensation as heavy ice delayed their season by several weeks due to huge icebergs and thick ice stretching for miles. New article explains the worlds oceans are warming 13% faster than thought, although the Atlantic, Pacific, Arctic and Antarctic all show cooling. Interesting.

Mt. Washington gets record snowfall as Massachusetts prepares for heat

More than 30 inches of snow enveloped Mount Washington Observatory this weekend — just days before parts of Massachusetts are expected to have temperatures in the 90s.

The snow started Saturday night at the New Hampshire observatory and continued through Monday, covering the mountain with about 33 inches before stopping, according to a Facebook post from the observatory.

A May snowfall is not unusual at the observatory, said Chris Kimble, a National Weather Service meteorologist. About 12 inches of snow typically falls in May at the observatory, which has an altitude of 6,300 feet.

But this weekend's storm broke a couple weather records, including the largest snowfall for a single day in May.

"In 1967, 22.2 inches fell, and this weekend we got 22.9 and counting," Kimble said.

The record for the largest single-storm snow in May was also broken, he said. From May 21 to 24, 1997, the observatory was hit with 30.6 inches of snow. This weekend, 33.3 inches fell.

So far, over 45 inches of snow have fallen at the observatory this month.

Atlantic ocean begins to cool, icebergs abound & global warming can't explain cosmic cycles

With the Atlantic Multi-decadal Oscillation beginning its 30 year cooling phase in the 60 year cycle, near record iceberg sightings dot the Canadian coastline. Excuses are give such as the Peterman Glacier developing a crack, the ice on Greenland calving as new ice builds in the center, any excuse except the real cause, a cosmic cycle. The late Holocene sea surface temperatures show a warm period at 1000AD, and cool period 100AD which we are beginning to repeat.

26 cm (10 inches) of snow recorded in eastern Finland on Mother's Day

Snow Finland
Brilliant sunshine and relatively balmy Mother's Day weather greeted mothers in some parts of southern Finland, but in other parts of the country, mums woke to a completely different scenario.

According to the Finnish Meteorological Institute, FMI, in Kuhmo, which lies in the southeastern corner of Kainuu in the east, the heavens dumped some 26cm of snow on Sunday.

In other parts of the eastern region, snowfall measured 20cm. However in areas such as Kajani and Sotkamo, the precipitation was more moderate, averaging just over 10cm.

The last time that so much snow was recorded in a 24-hour period between May 1 and 20 was in 1997.

By Sunday, Kainuu municipalities such as Paljakka in Puolanka had accumulated up to 93cm of snow on the ground, while other areas such as Pesiö in Suomissalmi had 53cm and Kajaani 13cm.

The National Weather Service reports that several areas of New England received snow this Mother's Day, including some parts of Maine.

The service says snow fell and accumulated in elevations about 1,500 feet early Sunday morning.

The foothills of the Berkshires in East Hawley, Massachusetts, with an elevation of 1,650 feet saw 4 inches.

Further north, Washington and Alexandria in New Hampshire both received snow. In Carroll, New Hampshire, heavy snow and fallen trees left some roads blocked.

Rare 'ice halo' visible around the moon in New Zealand

A rare "ice halo" visible around the moon overnight coincided with a big chill, with temperatures dropping below freezing point in both the North and South Islands.

Ashburton was the coldest spot on Sunday morning, with an icy temperature of -3.4C between 5am and 6am. Christchurch dropped to -2.9C, while in the North Island, both Masterton and Hamilton were -2.7C. "They'll be waking up to a really cold start," MetService meteorologist April Clark said. Hamilton was probably having the worst start to the day, she said.

"They have a little bit of fog around as well - they cool and get frost, and they also get fog, which is a bit miserable." Temperatures dropped even lower on Saturday night in Queenstown, dipping to -3.6C between 9 and 10pm when the skies were clear, before "heating up a little bit" when cloud set in. "It's really a huge difference when you get cloud - it's just like a little blanket over everyone."

Ice Age Cometh: Snow in Russia when it should be Spring?

The weather in Russia is a capricious lady. In the midst of the May holidays (May 6-9 in honor of Victory Day), many Russian cities experienced heavy snowfall—so instead of traditional shashlik (kebabs), social media were full of snowmen and snowy landscapes.

Some joked that it was because FC Spartak had just won the Russian soccer league for the first time since 2001—a huge surprise for everyone, including the gods in the sky. Others wrote that the Russian winter, a trusty ally of the Soviet army, had decided to take part in the Victory Parade. Still others congratulated each other on the forthcoming New Year.

The abundant snowfall in and around Moscow on the afternoon of May 8 was repeated two days later. According to forecasters, Moscow is approaching the record set in 1922, when more than 35 mm of precipitation fell in just a single day. Victory Day in Moscow was the chilliest since 1945. Meteorologists note that over the past 130 years the daytime temperature on May 9 had never previously dipped below +5°C. But this year saw temperatures in Moscow ranging from +3.6 to +4.6.

The snow must go on: May snow in the finest traditions of British rock group Queen.
