Review of 2019

YQM 2019
The data has been collected for 2019 which shows most major centres across Southern Canada were slightly below normal with only the Arctic region posting above average values.

Greater Moncton was no exception at 0.1 degree below normal which was in contrast to 2018 which was 0.4 degrees above normal.

Based on the thirty year period from 1981-2010, Moncton had more hot days and fewer frigid days but other categories were close to average.

Rainfall was above normal for Southeast New Brunswick while less snowfall was recorded for the year.

December 2019 – Mild with little snow

It felt like winter was on pause during December in Southeast New Brunswick.

After significant snow on 07-08 November, many thought winter arrived early again.

But more rain fell and the heaviest snow was a mere 9 cm – paltry by Greater Moncton standards.

Although the temperature remained below freezing on 13 days and most daytime highs were just slightly above zero, the thermometer did climb above 10°C on four occasions.

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.

Rainfall totals (in mm) as of 8am on 10 December 2019:

  • Mechanic Settlement, NB  94 mm
  • Saint John Airport  63 mm
  • Kejimkujik NP, NS  53 mm
  • Dorchester, NB  50 mm
  • Yarmouth, NS  43 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.

November 2019 – Colder and snowier

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.

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.

First snow of the season

Snow
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.

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.

A Blustery Halloween!

Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.

A low pressure system could bring at least 30 mm of rain to Southeast New Brunswick over the next 24 hours.

Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.

Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.

Forecasters say the wind may cause damage to buildings such as to roof shingles and windows.

The wind may not die down until early Saturday.

Fading tropical storm batters Ontario

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.

Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.

Wind gusts were up to 80 km/h in some locations with a peak of 104 km/h recorded at Port Colborne on Lake Erie.

Olga formed in the Gulf of Mexico several days ago and made landfall in Louisiana before quickly churning northward toward the Great Lakes.

Forecasters are calling for more wet weather and cooler conditions by Halloween.
