Late summer and early autumn have been cold in southern Alberta but a big snowfall suddenly made it seem like winter.

Heavy snow moved across the Rockies and the foothills today dumping between 20 and 40 cm of snow (including over 30 cm at Calgary International Airport).

Environment Canada warns the snow will continue into Wednesday morning with a few more centimetres expected.

Traffic also ground to a halt as vehicles became stranded on snowy and icy highways.

Juneuary!

When it snows in June it might as well be January which gives us a new month called Juneuary!

It may now be summer but an icy rain changed to snow in central Newfoundland and the Cape Breton Highlands today.

Gander set a new record with 2 cm of snow and Environment Canada said it has never snowed on 26 June before.

Thanks to a chilly rain, Greater Moncton reached a daytime high of only 11.0 C yesterday which was colder than the average overnight low of 12 C.

Average temperatures in Southeast New Brunswick have been running about three degrees below normal this month.

A slow moving low pressure system brought a wintry mix of snow, ice pellets, freezing rain, rain and strong winds to Southern Ontario and Southern Quebec over the weekend.

Icy conditions led to more than 1,600 highway crashes, numerous power outages from falling trees and downed lines, cancelled flights, transit delays and school closures.

Officials were forced to close the CN Tower due to falling ice from the structure.

Here are some totals from the spring storm as of 16 April at 2pm EDT:

  • Toronto Pearson Airport – 18 hours of ice pellets, 6 hours of freezing rain, 12 cm ice pellets.
  • Toronto Billy Bishop Airport – Peak wind gust of 96km/h
  • London – 14 hours of freezing rain with ice pellets
  • Windsor – 6 hours of freezing rain
  • Hamilton – 11 hours of ice pellets, 6 hours of freezing rain and ice pellets, 8 hours of freezing rain
  • Ottawa – 9 hours of freezing rain Sunday, 6 hours of freezing rain Monday, wind gusts to 70 km/h
  • Montreal – 9 hours of freezing rain Saturday, 4 hours of freezing rain Sunday, 3 hours freezing rain Monday
  • Quebec City – 5 hours of freezing rain Monday

Beast from the East 2.0

UK snowy

A blast of cold Siberian air – dubbed “Beast from the East 2.0” – has invaded the United Kingdom bringing heavy snow and icy conditions for the second time this month.

More than 10 cm snow fell in southwest England where a 100 km stretch of the A30 Highway was shut down forcing travellers to seek emergency shelter at a school in Okehampton.

Devon and Cornwall Police warned drivers to stay off the highways until snowplows cleared them and hundreds of schools were closed today.

Forecasters are watching for another wintry cold snap which could affect the UK during Easter weekend.

Meteorological winter 2017/18 is now in the books since the three month period of December, January and February is over but we all know winter is not over yet in Southeast New Brunswick.

What a ride it has been in Greater Moncton with temperatures fluctuating wildly from very mild to extremely cold in just hours and in one case in mere minutes.

Snowfall was lighter compared to normal especially in February but the bigger concern were frequent periods of mixed, icy precipitation such as freezing rain and ice pellets.

A few days ago it was extremely cold in Greater Moncton and today it felt like spring.

The unofficial high was 14.3 C which beats the record of 11.2 C from 2014 according to Environment Canada.

But emergency measures officials are warning New Brunswickers to be prepared for possible flooding this weekend with 50 to 100 mm of rain possible and a flash freeze warning.

The ground is mostly frozen and has a reduced ability to absorb heavy rainfall.

The temperature is forecast to fall below freezing by late Saturday which will lead to icy conditions.

Much of New Brunswick was under another extreme cold warning this weekend with a near record low of -22.3 C in Greater Moncton today (record is -23.3 C from 1945) and a bone-chilling wind chill near -36.

Environment Canada is calling for temperatures to moderate this week with a return to near normal values and even above freezing temperatures by Thursday.

The Northeast United States has also been under a cold snap and the thermometer bottomed out Sunday with record lows in a number of cities including Burlington, Vermont at -29 C and Portland, Maine at -24 C.

Boston, Massachusetts tied its record low of -19 C just days after digging out from 34 cm of snow during the ‘bomb cyclone’ and being inundated with icy floodwaters from the highest tides in a century.

Freezing rain creates icy conditions

Streets and highways in Greater Moncton turned into skating rinks early this evening after freezing rain began falling through Central and Southeast New Brunswick.

Social media users mentioned how numerous vehicles were sliding off the roads in icy conditions and Magnetic Hill had become an ice sheet.

A low pressure system from the Northeastern United States brought mixed precipitation which eventually changed to rain.

Meantime, Environment Canada is monitoring a major snowstorm expected Christmas Day which could bring 20 cm snow to parts of New Brunswick.

The defining weather event of January 2017 in New Brunswick was the devastating ice storm which brought down power lines and poles leaving more than 133,000 electricity customers in the dark for days.

Freezing rain and ice pellets began falling in Greater Moncton and Southeast New Brunswick on 25 January and the storm eventually moved northeast to Miramichi and the Acadian Peninsula.

Emergency shelters were set up in churches and community centres and the military was called in to help after some households were still without power a week later.

While overnight lows became frigid during the early and middle parts of the month, daytime highs were generally much milder than usual.

While Greater Moncton was hard hit by this week’s ice storm so was much of eastern New Brunswick including the Acadian Peninsula.

At least three communities have declared states of emergency – Tracadie-Sheila, Lameque and Shippagan – in what has been the most devastating ice storm in recent memory.

Two deaths have been reported and many others hospitalized for carbon monoxide poisoning related to an alternate source of indoor heating amid the massive power outages.

Power poles have snapped in half under the weight of ice-laden lines and downed trees and branches have shut down roads as the cleanup begins.

As of Saturday 28 January at 9am, NB Power reports about 46,000 customers are still without power and almost half are in the Acadian Peninsula.
