January 2020 – Warmer than normal

Sunset at Irishtown Nature Park, 25 January 2020 (Dearing)

Glancing at the data for January 2020, one would think it was as cold if not colder than normal in Southeast New Brunswick.

The thermometer sank below -10°C on sixteen days while four of those days dropped to -20°C or lower during the month.

Despite the frigid weather, January was in fact almost three degrees above normal in Greater Moncton.

Despite two major snowfalls (including one event near 30 cm) and some rainfall, precipitation was close to the thirty-year average.

Wind & rain cause damage

Roof damage at apartment building, Heather Way, 10 Dec 2019 (City of Saint John)

Strong winds and heavy rain from a strong low pressure system caused damage to properties and localized flooding in New Brunswick and Nova Scotia.

The Saint John area was hard hit with wind gusts up to 95 km/h which led to power outages and roof damage to at least two apartment buildings.

No one was hurt but all tenants were evacuated and assisted by the Red Cross.

Many roads were closed due to flooding or fallen trees and there were voluntary evacuations in Sussex in low lying areas.

The storm also brought mild, record-breaking temperatures with highs of 11°C in Edmundston and 12°C in Bathurst and Woodstock.

Greater Moncton hit 13.7°C but the record for 10 December was 15°C from 1957.

  • Mechanic Settlement, NB  94 mm

Heavy rain may cause flooding

Snow settles in Moncton, 05 Dec 2019 (Dearing)

The latest low pressure to invade the Maritimes is bringing heavy rain and strong winds to Southern New Brunswick and Northern Nova Scotia.

Environment Canada has issued a rainfall warning with up to 70 mm possible especially along the Fundy coast and strong winds gusting up to 90 km/h.

Meteorologists say that much rain is a lot for frozen ground to absorb and along with an existing snowpack could create localized flooding.

After a few days with below freezing temperatures, the small amount of snow in Greater Moncton has been taken away by the rain and a mild high of 12°C.

The forecast is calling for much colder air behind this system with some snow likely on Wednesday.

December starts icy in Ontario

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.

Colorado Low impacts Maritimes

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.

October 2019 – Gradual easing into fall

Centennial Park, Moncton, 14 Oct 2019 (Dearing)

Daytime highs were consistently in the mid-teens in Southeast New Brunswick during October which usually sees a sharp drop in temperature as the month progresses.

The average temperature was 0.7°C above normal in Greater Moncton with two days failing to reach 10°C and the warmest maximum on the last day, 19.3°C.

Six days had lows below freezing with some light frost but there was no hard freeze allowing vegetation to flourish.

The precipitation total mostly came from five rainfall events with not a single snowflake recorded.

Fall foliage peaked prior to Thanksgiving weekend and several strong wind events left few leaves on trees by Halloween night.

September snow in the West!

Autumn began just a few days ago but it already looks and feels like winter in parts of British Columbia, Alberta and Saskatchewan.

A strong low pressure system prompted snowfall and winter storm warnings as up to 100 cm of snow fell across southern Alberta.

Gusty winds behind the system created blowing and drifting snow making highway travel treacherous.

Many early season snowfall records have been broken.

Snowfall amounts (in cm) as of 1pm MDT, 30 September:

  • Calgary 32
  • Claresholm  40-45
  • Lethbridge  50-60
  • Taber  60
  • Cardston area  70-90
  • Waterton Park  95

Fall preview for Atlantic Canada

After what seemed like a short summer – it didn’t get started until early July in Southeast New Brunswick – The Weather Network has unveiled its 2019 fall forecast.

  • Much of Atlantic Canada should see above-average rainfall due to a few systems that tap into tropical moisture and bring excessive totals.
  • Above normal temperatures are expected to dominate across the southern Maritimes, while typical fall temperatures are expected elsewhere.

Dorian packs powerful punch

Dorian damage in Halifax’s West End, 08 Sept 2019 (NS Power)

Hurricane Dorian has left a path of destruction across the Maritime Provinces despite being downgraded as it crossed the region.

The Canadian Hurricane Centre says Dorian was an intense post-tropical storm as it made landfall at 7:15pm ADT Saturday in Sambro, 25 km southwest of Halifax.

Dorian brought destructive winds, flooding rains and powerful storm surges to much of Nova Scotia, southern New Brunswick and Prince Edward Island.

A construction crane collapsed and century old trees toppled onto homes, businesses, vehicles and streets in Halifax.

Public works staff are scrambling to clean up the mess and power crews are trying to restore electricity to the tens of thousands without it.
