Hurricane Dorian defined September for Southeast New Brunswick, Prince Edward Island and Nova Scotia.

Although downgraded before making landfall near Halifax, Dorian was still a very destructive storm.

Powerful winds toppled century-old trees onto power lines, a month’s worth of rain drenched the region in hours and a vicious storm surge tossed boats around like toys.

If it hadn’t been for Dorian, the month would have been quite dry in Greater Moncton.

September also lacked heat with slightly below normal temperatures thanks to chilly nights and cool daytime highs which often struggled to reach 20°C.

Spring 2019 in review

Spring 2019
Meteorological spring in Southeast New Brunswick turned out to be colder and much wetter than normal compared to the 30-year average.

While March and April both had above normal temperatures, May was colder by a significant 2.4 degrees which brought down the overall seasonal average.

Rainfall was heavy in April and May and while snowfall was below normal for the three month period, the final snow flurries were spotted as late as 21 May.

“Sprinter” continues

Sprinter is a portmanteau of spring and winter which aptly describes the recent weather in Southeast New Brunswick.

Already mid-May, Environment Canada indicates Greater Moncton is running about three degrees below normal for the month.

Snow mixed in with rain last night and 0.6 cm was recorded at the airport.

Today’s daytime high was 5.3°C and the forecast shows little change for tomorrow.

The Victoria Day long weekend is expected to bring some sunshine but temperatures will remain below seasonable.

Winter 2018-19 in Review

Winter 18-19
Wintry weather will undoubtedly continue in New Brunswick for the next few weeks but meteorological winter (December, January and February) is officially over.

In Greater Moncton, winter proved to be slightly colder than normal (0.3 degrees cooler) although the extreme low was not as cold as previous years.

Precipitation was about average for the season with slightly above normal rainfall and slightly below normal snowfall.

December 2018 – Cold & dry

December turned out to be another cold month in Greater Moncton continuing a trend which began in October.

An early Arctic air mass kept daytime highs below freezing for a lengthy ten day stretch.

The month did prove to be less stormier than November with below normal rainfall and snowfall.

While Southeast New Brunswick had a snow cover for a few weeks prior to Christmas, it had mostly disappeared by 25 December.

Bitter cold hangs on

An Arctic air mass continues to have its grip over the Maritimes with today marking the sixth day of below freezing temperatures in Greater Moncton.

The early morning lows dropped to -16.1°C yesterday and -16.5°C today.

Brisk northwest winds have also created bitter wind chills into the -20s this weekend giving a risk of frostbite on exposed skin.

The normal high for early December is 0°C and the low is -8°C.

Environment Canada says temperatures may not climb above freezing until Friday making this one of the longest cold snaps in recent memory.

Weather Network unveils winter forecast

wintertemp19
The Weather Network believes the harsh winter conditions this November in New Brunswick are just a preview of the upcoming season.

Temperatures will likely be below normal this season but periods of mild weather can still be expected.

An active storm track along the Atlantic coast will mean many systems delivering above average precipitation including snow, rain and freezing rain.

A developing El Nino should bring a warmer, drier winter for Western Canada and a colder, wetter winter from the Great Lakes to Atlantic Canada.
