A strong low pressure system brought snow and strong winds to Alberta creating poor visibility and even thunderstorms and a possible tornado were reported.
Emergency officials scrambled to respond to more than 120 road crashes in Calgary on Sunday due to slippery, treacherous conditions after about 15 cm snow fell.
The spring blizzard continued to move across the Prairies where it dumped up to 45 cm on southwestern Saskatchewan including the Cypress Hills area.
The storm crossed into Manitoba with as little as 5 cm in the southeast to about 30 cm in the southwest.

A so-called bomb cyclone brought blizzard conditions to Colorado and now heavy rain, flooding and even tornadoes to the U.S. Midwest.
The weather bomb occurs when there is a rapid drop in atmospheric pressure over a 24 hour period.
Further north, the storm is dumping snow across Minnesota as it moves into northwestern Ontario.
Severe thunderstorm watches have been posted for Southern Ontario with strong winds expected along with heavy rain.
New Brunswick will the effects this weekend with significant rainfall and gusty winds in the forecast.
Labrador typically receives some of the highest amounts of snow in Canada during the winter which stretches from October to April – and this season is no exception.
A coastal blizzard has buried the community of Makkovik with almost 110 cm of snow falling since late last week.
Social media posts have showed entrances to buildings blocked and the snow depth higher than local residents trying to dig out.
Based on the 30-year average, Makkovik usually gets about 411 cm per year with only July and August not recording measurable snow.

Snow covered highway near Okehampton, Devon, UK, 19 March 2018 (Keene/PA)
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.
Snow is piled high in Boston, MA, USA, 05 Jan 2018 (AP)
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.
Powerful storm surge causes flooding along the waterfront in Halifax, NS, 05 Jan 2018 (Twitter)
The ‘bomb cyclone’ or ‘snow hurricane’ – featuring a dramatic drop in atmospheric pressure when warm and cold air collided – has left the Maritimes and spared Southeast New Brunswick from the worst of its fury.
While strong winds were a factor throughout the region, Greater Moncton received less snow compared to further north and west.
To the south and east, more rain fell along with hurricane-force winds (up to 200 km/h gusts in western Cape Breton) which created powerful storm surges causing flooding along the coast.
Here are some totals from Environment Canada and local estimates:
- Greater Moncton Airport 14 cm snow, 10 mm rain, 91 km/h wind gust
- Bathurst 58 cm snow, 80 km/h wind gust
- Fredericton 30 cm snow, 78 km/h wind gust
- Saint John 5 cm snow, 20 mm rain, 87 km/h wind gust
- Halifax Stanfield Airport 40 mm rain, trace snow, 122 km/h wind gust
The storm may have departed but Arctic air has filtered back into the Maritimes which will mean a bitterly cold weekend.
“Bomb cyclone” south of the Maritimes, 04 Jan 2017 (earth.nullscholl.net)
An powerful Nor’easter has arrived in the Maritimes with strong, gusty winds bringing heavy rain for Nova Scotia and a snow/ice pellets/rain for New Brunswick and Prince Edward Island.
Winds were hurricane-force in the Halifax region at 117 km/h and thundersnow – a thunderstorm with snow – was recorded in Sydney.
Storm surge warnings are in place along the Atlantic coast as water levels will be high enough to cause some coastal flooding.
In Greater Moncton, snow began falling around noon with freezing rain/ice pellets by late afternoon and rain by evening.
Environment Canada says the storm will move out of the region by Friday afternoon but more frigid air is filtering in behind the system which will mean a very cold weekend.
Snow accumulates in Tallahassee, Florida, USA, 03 Jan 2018 (Twitter)
For the first time in 28 years, the capital of America’s Sunshine State had measurable snow.
Tallahassee may occasionally see snowflakes in winter but today was only the fourth time since 1950 that snow actually accumulated on the ground.
The wintry blast was thanks to a so-called bomb cyclone which originated off Florida’s east coast and is barreling up the Atlantic toward the Maritimes.
The intense storm system also brought heavy freezing rain to South Carolina and blizzard warnings have been posted from Virginia to Maine.
Environment Canada has issued a winter storm warning for Greater Moncton and Southeast New Brunswick with 30 cm of snow/ice pellets and 10 mm of rain as the temperature finally climbs above freezing.
The thermometer has not risen above zero since Christmas Day and seven straight days have been below -10 C.
Several weather outlets are forecasting a major winter storm will hit the Maritimes bringing heavy snow and strong winds to New Brunswick just days into 2018.
Blizzard conditions are possible along with large waves and high water levels along the coast.
Nova Scotia may get more rain along the Atlantic coast while a rain/snow mix is likely inland.
Until the storm arrives, Arctic air remains firmly in place with several cities in Ontario setting new record lows on New Year’s Day including -22.6 C at Toronto Pearson Airport and -28.6 C at Ottawa Macdonald-Cartier Airport.
