Return to winter

A strong low pressure system is expected to bring a lot of snow, some rain and wind to Southeast New Brunswick starting Thursday night.

About 15 cm could fall in Greater Moncton prompting Environment Canada to issue a snowfall warning.

Strong winds will coincide with high tide along the Northumberland Strait creating storm surge.

This could be the heaviest snowfall event since 01 March when 14 cm fell.

Spring-like weather ends

The last few days have felt like spring in New Brunswick but the warm spell is about to end.

Temperatures have soared as high as 10°C in some areas.

The normal maximum for late February is about 0°C in Greater Moncton.

Recent daytime highs:

  • 6.1°C on 23 Feb
  • 7.3°C on 24 Feb
  • 6.0°C on 25 Feb
  • 4.0°C on 26 Feb

However, winter is returning as a low pressure system brings mixed precipitation to Ontario and Quebec with the Maritimes next in its path.

Environment Canada has issued various weather warnings and up to 25 cm of snow and ice pellets could fall starting late Thursday into Friday.

Coldest, snowiest yet this winter

On the heels of the coldest weather so far this winter in Greater Moncton with lows of -21°C comes the heaviest snowfall to date.

A Colorado Low arrived in the Maritimes on Sunday after delivering a blow to the middle of the continent including Ontario and Quebec.

Since it was already very cold across Southern New Brunswick, the snow that fell was light and dry – unlike so-called “heart attack” snow which is heavy and wet.

Snowfall totals (in cm):

  • Minto area  31
  • Greater Moncton Airport  25
  • Fredericton area  16
  • Saint John Airport  13
  • Miramichi  10
  • Bathurst  4

Storm brings snow to Ontario & Quebec


A Colorado Low tracked across Lake Huron on Saturday and brought snow to nearly all of Ontario and Southern Quebec with the first major amounts this winter.

Strong gusty winds up to 100 km/h in some areas also created blowing snow.

The low pressure system continued through the Northeastern United States and impacted the Maritimes on Sunday.

Snowfall amounts (in cm):

  • Marathon  30
  • Thunder Bay  21
  • Ottawa  20 (new daily record for 18 January)
  • Kitchener-Waterloo  19
  • Toronto Pearson Airport  17.2 (new daily record for 18 January)
  • Montreal  17
  • London  16
  • Kenora  15

Hours of ice pellets!

Back-to-back low pressure systems brought a messy mix of precipitation to much of the Maritimes over the weekend.

Rain began falling Saturday with a near record warm high of 11 C in Greater Moncton which melted any snow on the ground.

However, the next system brought colder temperatures and more than ten hours of ice pellets (sleet) in Southeast New Brunswick sometimes mixed with snow and freezing rain.

About 15 cm of ice pellets and snow accumulated Sunday which forecasters say is quite rare and it was certainly heavy to move.

Nova Scotia hit with heavy snow

Just days after the first major snowstorm of the season hit Nova Scotia, another low pressure system intensified as it tracked south of the province on Wednesday.

The eastern mainland and Cape Breton Island received lots of snow – more than 60 cm fell in some areas.

Southeast New Brunswick got off relatively easy with about 10 cm recorded in Greater Moncton.

Here are some snowfall totals (in cm) from 09 January at 5pm AST:

  • Pictou area – 63
  • Truro – 42
  • Ingonish Beach – 38
  • Halifax Stanfield Airport – 30
  • Dartmouth – 28
  • Sydney – 27
  • Charlottetown, PE – 23
  • Kentville – 20
  • Yarmouth – 15

First storm of 2020

Just days into the new year, a low pressure system has brought mostly snow to Atlantic Canada especially near the ocean.

For most of Nova Scotia, it was winter’s first major snowfall with up to 15 cm at Halifax Stanfield Airport and nearly 40 cm in Sydney.

The storm grazed Greater Moncton with only 3 cm of snow.

After leaving the Maritimes, the system brought 42 cm snow to St. John’s, Newfoundland and 30 cm to the Burin Peninsula with a peak wind gust of 106 km/h in Bonavista.

Meantime, forecasters say another low pressure system is coming midweek.

Wintry mix for New Year’s Eve

The same storm system which impacted Ontario and Quebec is now creating travel havoc in the Maritimes with a mixed bag of precipitation.

Snow along with ice pellets began in Southwest New Brunswick on New Year’s Eve morning and gradually spread to Greater Moncton by early afternoon.

About 14 cm of snow and ice pellets could accumulate in the Southeast before a changeover to rain around midnight as temperatures rise above freezing.

Snowfall warnings have been posted in western and northern New Brunswick with 15 to 30 cm likely with lesser amounts for Prince Edward Island and mostly rain is forecast for mainland Nova Scotia.

UPDATE

Moncton received 5.4 cm of snow, Saint John had 3.4 cm while about 10 cm fell in Fredericton but near 30 cm in Woodstock.

Storm sweeps Ontario

Ontario is so large and sprawling that it’s rare one storm could impact most of the province but that’s what happened Sunday into Monday.

A large low pressure system brought severe winds to the southwest, hours of freezing rain in the east and heavy snow in the northwest.

Temperatures also soared briefly in the Greater Toronto Area with a new record high of 10.2°C set at Pearson Airport.

  • Ottawa Int’l Airport – 22
  • Sudbury – 20

Mild but stormy conditions

Another intense low pressure system moved through the Maritimes on the weekend bringing a new round of heavy rain and strong winds.

After a bone-chilling start, winds changed direction and a southerly flow pushed the high in Greater Moncton to 13.8°C – close to the record of 13.9°C from 2008.

Winds were strong with gusts up to 87 km/h in Southeast New Brunswick and a peak of 91 km/h reported in Bathurst.

As the storm headed to Newfoundland, cold air plunged into the region and temperatures fell below freezing and may stay that way for several days.
