After exiting Ontario, a Colorado Low moved into the Maritimes bringing freezing rain and rain to Nova Scotia along with mixed precipitation to Southeast New Brunswick.

The system shut down schools in many parts of the region on Tuesday with icy roads being a major factor.

Greater Moncton had several hours of freezing rain and ice pellets mixing with snow (3 cm) and later rain (15 mm) as the temperature climbed slightly above freezing.

Northern and western New Brunswick received mostly snow with 10 cm in Fredericton, 18 cm in Miramichi and 27 cm in Woodstock.

A major winter storm made its way across the United States during the American Thanksgiving weekend disrupting travel plans for millions.

The massive system began on the West Coast as a bomb cyclone bringing wind gusts up to 160 km/h and heavy amounts of snow in the mountains.

Strong winds accompanied by a mixture of rain, freezing rain, ice pellets and snow fell from the Great Plains to the Midwest and into the Northeastern U.S.

Boston recorded 20 cm of snow with more than 60 cm falling in other parts of New England before the system headed to the Maritime Provinces and Newfoundland.

A low pressure system delivered an icy mix of precipitation to Southern Ontario on Sunday with freezing rain and ice pellets turning highways and walkways into ice rinks.

Ontario Provincial Police say heavy snow shut down a section of Highway 401 near Kingston after a 30 to 40 vehicle pileup with more than a dozen injured and one fatality.

At least 500 road crashes were reported in the Greater Toronto Area and numerous flights were either cancelled or delayed at Pearson Airport.

Tens of thousands lost electricity after ice-laden tree branches fell onto power lines,

Several towns and cities were forced to cancel their Santa Claus Parades due to the extreme weather.

November got off to a mild start in Greater Moncton – the monthly high 19.4 C was actually 0.1 degrees warmer than October’s maximum – but temperatures quickly tumbled especially overnight.

Only two nights were actually above freezing with the coldest weather around the middle of the month.

The first measurable snow was recorded on 07-8 (18.8 cm) which was more than half of the November total and rainfall was lighter than usual.

Daytime highs struggled to climb above freezing especially during the last two weeks which led to a below normal monthly average.

A Colorado Low tracked through the Maritimes today bringing mixed precipitation and strong winds.

The system brought the first major snowfall to Nova Scotia with 23 cm at Halifax Stanfield Airport and lesser amounts in the city but it caught drivers and plow operators off guard creating gridlock.

About 10 to 20 cm of snow also fell in central and southwestern New Brunswick where some schools closed with slippery road conditions.

Greater Moncton had a rain/snow mix this morning with 2 cm before it changed to rain.

As this system moves off to Newfoundland, brisk winds behind it will produce gusts up to 90 km/h with snow squalls expected along coastal areas.

Sharp drop in temperature!

Snow began falling in Southeast New Brunswick Monday night and later changed to freezing rain and then rain by Tuesday afternoon.

The temperature climbed to a balmy 14°C in Greater Moncton and 18°C in Greenwood, Nova Scotia.

But as the low pressure system moved out of the Maritimes toward Newfoundland, winds shifted to the northwest causing the thermometer to drop rapidly Tuesday night with a return to snow when it fell to freezing again.

Overnight low records could be challenged in the region by early Thursday as cold Arctic air takes hold.

Environment Canada says Toronto marked its earliest major snowfall on record with about 15 cm.

Arctic air has filtered in behind the storm prompting the city to issue an extreme cold weather alert with a possible overnight low of -15°C.

Heavy, wet snow creates chaos

Some drivers were prepared when snow entered the forecast for the first time this week and had their winter tires installed.

But many drivers were caught off guard by the heavy, wet – sloppy – snow which fell across Southern New Brunswick, Prince Edward Island, northern Nova Scotia and southwestern Newfoundland.

A low pressure system brought rain on Thursday but snow fell by evening as the temperature dropped to the freezing point.

The snow continued throughout Friday creating slippery roads which left plow operators scrambling to deal with the early blast of winter.

Many minor accidents were reported with vehicles sliding into the ditch.

The Trans Canada Highway at Cobequid Pass was forced to close for several hours Friday night after numerous tractor trailers got stuck in snow and blocked the road.

Snowfall amounts (Thu-Fri) in cm:

  • Corner Brook 19.4
  • Greater Moncton 18.8
  • Fredericton 10-15 (estimate)
  • Deer Lake 13
  • Saint John 8.9
  • Halifax Stanfield 5.8
  • Charlottetown 3.9

First snow of the season

A low pressure system moving through the Maritimes brought the first snow of the season to Southeast New Brunswick today.

A cold rain eventually turned to snow in Greater Moncton and 7.2 cm fell with Environment Canada calling for up to 10 cm tomorrow.

As the above chart shows, the first measurable snow in the region is typically recorded from late October to late November.

Tire shops have reportedly been busy this week as drivers scramble to get their snow tires installed.

Manitoba declares state of emergency

The Manitoba government declared a state of emergency on Saturday after a powerful storm dumped heavy rain, freezing rain, snow and wind to southern portions of the province this week.

Amid the early winter blast, Manitoba Hydro is trying to restore electricity to thousands of residents after numerous trees and branches – many still covered in leaves – fell onto power lines with winds gusting up to 100 km/h.

The storm was so bad it forced the temporary closure of the Trans Canada Highway from Winnipeg to the Saskatchewan border.

Southern Manitoba got blasted after a Colorado Low moved in from the United States where it brought dramatic temperature drops and heavy snow to the Great Plains states.

The next concern for local emergency measures officials will be flooding as the snow melts given the rising temperatures forecasted over the next few days.

Snowfall totals as of 1pm CDT on Saturday, October 12th:

  • Carberry  74 cm
  • Morden  64 cm
  • Winnipeg  34 cm
  • Dauphin  30 cm
  • Brandon  29 cm
