Thunderstorms cool off Eastern Canada

Thunderstorms rolling across Southern Ontario and Southern Quebec this weekend brought an end to oppressive heat and humidity.

Toronto residents were trying to keep cool Saturday when the mercury soared to 33.0°C with a stifling humidex of 44 and Montreal reported similar conditions.

In the Maritimes, even typically cooler coastal areas were warm with new record highs set in Saint John and Grand Manan.

The temperature in Greater Moncton peaked at 32.4°C which fell short of the record of 33.5°C from 1991.

A brief, violent thunderstorm hit Halifax on Sunday afternoon with flash flooding and strong winds knocking out power to more than 44,000 Nova Scotians.

Brief heat wave ends

In less than two hours, the temperature in Greater Moncton dropped from 31.1°C to 24.0°C late this afternoon – a difference of seven degrees.

A cold front moved through New Brunswick with thunderstorms marking an abrupt end to the summer’s first brief heat wave.

Environment Canada even issued a tornado warning for the Grand Lake area after a possible twister developed south of Boiestown.

The warning was lifted after 30 minutes and no damage or injuries were reported.

Record highs have been broken in a number of communities across the Maritimes.

Friday, 05 July:

  • Kouchibouguac NP, new record 31.1°C, old record 33.9°C from 1939
  • Grand Manan, new record 31.7°C, old record 30.0°C from 1999
  • Halifax Stanfield Airport, 32.7°C, old record 31.4°C from 2013

Greater Moncton was within a hair of breaking a record Saturday and Sunday it was the warmest on that date since 2013.

  • 05 July, high 34.0°C, record 34.2°C from 2018
  • 06 July, high 31.4°C, record 35.0°C from 1911

Chilly nights!

Last Zero
The last couple of nights have been chilly across New Brunswick with overnight lows in the low single digits.

While Greater Moncton fell to 5.5°C which was a few degrees away from the record, the same minimum in Bouctouche was cold enough to set a new low.

Edmundston dipped to a nippy 1.1°C which tied its record as did Grand Manan when it dropped to 3.8°C.

Over the last six years in Greater Moncton, the chart above shows temperatures have not fallen to the freezing point or lower after early June.

Deep snow cover across N.B.

NB map
This has been a very snowy winter across northern New Brunswick with Edmundston and Bas-Caraquet recording 114 cm of snow on the ground as of today (06 March).

Some unofficial reports have indicated a snow depth of more than 160 cm in some mountainous areas.

Southern New Brunswick also has plenty of snow but often it has been mixed with rain, freezing rain or ice pellets which have lowered accumulations.

Greater Moncton now sits at 53 cm (the most so far this season) and snowbanks are getting high enough to cause visibility issues at some intersections.

For the third time since the start of 2019, Southeast New Brunswick was hit with snow.

Another low pressure system initially brought snow with 21 cm recorded in Greater Moncton following briefly by ice pellets and then 5 mm of rain as the temperature climbed above freezing.

Higher amounts of snow fell in central and northern New Brunswick while more rain fell over mainland Nova Scotia with localized flooding in the Halifax region.

Environment Canada expects calmer but colder conditions over the next few days.

Bitter cold across N.B.

cold jan 3

It doesn’t get that much colder than this in New Brunswick – thankfully! – and this is certainly the coldest weather so far this winter.

The thermometer fell to a bone-chilling -21 C in Greater Moncton this morning with a wind chill of -28.

The cold spot in the province was Edmundston with a low of -31 C which makes a temperature of -4.4 C in Grand Manan balmy by comparison.

Miscou Island set a new record low of -22.9 C according to final figures from Environment Canada beating the old record of -22.2 C from 1968.

Winter arrives with a deluge

Although it has felt like winter for weeks now, the solstice officially arrived in New Brunswick at 6:23pm AST Friday.

Oddly enough the weather now feels more like spring with a high of 10.1 C on Friday and 12.8 C today in Greater Moncton thanks to southerly winds and heavy rain from an intense low pressure system.

But the warmth will be short-lived as winds change direction to northwesterly behind the system and temperatures will fall below freezing on Sunday.

Rainfall amounts as of 22 December at 12pm AST:

  • Mechanic Settlement  92 mm
  • St. Andrews  79 mm
  • Grand Manan  73 mm
  • Alma  60 mm
  • Fredericton  51 mm
  • Saint John Airport  42 mm
  • Miramichi  31 cm
  • Greater Moncton  about 20 mm

Michael partly to blame for rain

Starting late Wednesday and lasting into Friday, a warm front and low pressure system eventually combined with moisture streaming northward from Tropical Storm Michael.

As these two systems began to interact, a significant amount of rain fell over parts of the Maritimes.

Rainfall summary in millimetres as of Saturday 5am ADT:

  • Doaktown: 47.2
  • Greater Moncton Airport: 39.4
  • Fredericton: 36.2
  • Saint John: 35.6
  • Grand Manan: 34.5
  • Halifax Stanfield Airport: 55.4
