Powerful winds pummel Maritimes

Tree topples over following powerful winds, 04 Nov 2018 (NB Power)

The powerful hurricane-force gusts knocked out electricity to more than 100,000 customers in New Brunswick during the height of the storm.

Temperatures were very mild thanks to a southerly flow with highs exceeding 20°C in some areas including a new record of 21.7°C in Cheticamp.

March 2018 – Stormy!

Winter storm

Whiteout conditions during a winter storm, west end Moncton, 08 March 2018 (Dearing)

Although March came in like a lamb, it behaved like a lion in the days to follow with four Nor’easters over two weeks in Southeast New Brunswick.

The first storm brought 15 cm, the second and third storms each delivered 16 cm and the fourth packed the biggest punch with 30 cm.

By 23 March, the snow cover in Greater Moncton had reached 40 cm which was the heaviest of the winter even though it was already spring.

Temperatures during the first half were mild averaging near the freezing point with brief cold snaps around the middle and near the end of the month.

Winter 2017/18 – Riding a Rollercoaster!

Meteorological winter 2017/18 is now in the books since the three month period of December, January and February is over but we all know winter is not over yet in Southeast New Brunswick.

What a ride it has been in Greater Moncton with temperatures fluctuating wildly from very mild to extremely cold in just hours and in one case in mere minutes.

Snowfall was lighter compared to normal especially in February but the bigger concern were frequent periods of mixed, icy precipitation such as freezing rain and ice pellets.

Ontario heat!

It felt more like mid-spring than late winter across Southern Ontario today.

A mild air mass combined with strengthening February sunshine to set new record highs in the region.

Environment Canada reports April-like maximums for 28 February:

  • Sarnia,  16.8 C, old record 15.1 C from 2016
  • Toronto Pearson Airport,  16.2 C, old record 14.0 C from 2016
  • Windsor,  16.1 C, old record 13.6 C from 2017
  • London,  15.1 C, old record 14.2 C from 2016
  • Kitchener-Waterloo,  15.0 C, old record 12.4 C from 2016

TWN unveils spring forecast

TWN spring

The Weather Network has taken a look ahead at the months of March, April and May for Atlantic Canada…

While it has been a relatively mild winter across the region, winter will still have several parting shots, including the threat for a few Nor’easters.

For some places, the biggest snowfall of the year could still be on the horizon (keep in mind the context – some areas have not had a classic winter storm).

Back and forth temperature swings should come close to offsetting, but with more potential for warmth to outweigh the periods of colder weather.

An active storm track will tap into subtropical moisture at times and bring above normal precipitation to most of the region through the spring season.

Spring-like record breaker!

Warm spring-like sunshine could be felt on my western facing balcony this afternoon in northeast Moncton and for few precious minutes it almost felt like winter was over.

The thermometer climbed to 12.9 C at the Greater Moncton International Airport which just barely eclipsed the record high of 12.8 C from 1953.

Other record highs were set across the Maritimes including 13.8 C in Cheticamp, Nova Scotia and 10.4 C in Edmundston.

But further to the west, the temperature climbed to a balmy 17.6 C in Sherbrooke, Quebec.

Ontario warmth heading East!

Feels like spring in N.B.

A snow free downtown Moncton, 28 Jan 2018 (Dearing)

With a daytime high of 7 C, it felt more like spring than midwinter along the Riverfront Trail in Moncton today.

Skateboarders instead of snowshoers were found along with joggers in shorts and T-shirts and a group having a picnic in the late afternoon sun.

A lack of snow cancelled numerous winter activities this weekend and ski resorts put snowmaking machines into overdrive to open just a handful of runs.

Environment Canada says winter is returning with a low pressure system arriving Tuesday with up to 15 cm of snow possible in Southeast New Brunswick.

Snow vanishes!

Bare ground in west end Moncton after rain washes away snow cover, 24 Jan 2018 (Dearing)

The snow cover in Greater Moncton has disappeared after the latest storm system rolled through with mixed precipitation and mild temperatures.

Rainfall amounts varied from 20 to 70 mm across New Brunswick, up to 8 hours of freezing rain fell in Gagetown and 20 cm of snow was recorded in Bathurst and Edmundston.

Record highs for 23 January were set in Saint John at 10.4 C and St. Stephen reached 11.3 C.

Since a consistent snow cover began on 09 December in Southeast New Brunswick, the ground has been bare a couple of times for short periods.

Another roller coaster ride!

A low pressure system from the west is bringing another mixed bag of precipitation to the Maritimes and once it departs more cold air will filter in behind it.

Schools were cancelled in New Brunswick today as snow began in the morning followed by a changeover to ice pellets and freezing rain and eventually to rain as the temperature climbed above freezing.

Flooding is possible again since the partially frozen ground is less able to absorb heavy rainfall.

Environment Canada issued a freezing rain warning for Greater Moncton but it was dropped later in the day with less than an hour of ice pellets/freezing rain recorded.

The temperature is expected to reach 10 C by early Wednesday before plunging to -13 C by early Thursday – a difference of 23 degrees in less than a day.
