From cold to hot

Leaves are finally bursting out, Irishtown Nature Park, 24 May 2020 (Dearing)

Numerous record lows were set across the Maritimes early Sunday morning as temperatures plummeted under clear skies and light winds.

But the cold will be replaced by heat as the jet stream surges north over Eastern Canada this week.

Environment Canada has issued a special weather statement for New Brunswick with unseasonably warm weather expected for late May.

Records will be challenged in Greater Moncton as daytime highs soar to 30°C and humidex values reach the mid-30’s.

New record lows set on 24 May:

  • Woodstock -4.7°C
  • Edmundston -3.0°C
  • Grand Manan -2.8°C
  • Bouctouche -1.9°C
  • Saint John -1.6°C
  • Kejimkujik NP -1.6°C
  • Summerside -1.4°C

Polar vortex brings cold, snow

It’s the middle of May and spring has barely appeared in New Brunswick so far and now an intense low pressure system has brought a wintry blast.

Greater Moncton had strong winds along with a cold rain which later turned to snow and a couple centimetres accumulated on colder surfaces like vehicles.

But the central, western and northern parts of the province got blasted with more than 30 cm of heavy, wet snow in some areas.

Meteorologists say cold air from the polar vortex continues to loom over eastern North America with new record lows set in Ontario this weekend and New York City recorded its latest trace of snow since 1977.

Snowfall amounts, 10 May at 3pm ADT (cm):

  • Woodstock  33
  • New Maryland  24
  • Bouctouche  22
  • Grand Falls  20
  • Miramichi  20
  • Fredericton  9
  • Bathurst  6

Messy mix falls over Maritimes

After exiting Ontario, a Colorado Low moved into the Maritimes bringing freezing rain and rain to Nova Scotia along with mixed precipitation to Southeast New Brunswick.

The system shut down schools in many parts of the region on Tuesday with icy roads being a major factor.

Greater Moncton had several hours of freezing rain and ice pellets mixing with snow (3 cm) and later rain (15 mm) as the temperature climbed slightly above freezing.

Northern and western New Brunswick received mostly snow with 10 cm in Fredericton, 18 cm in Miramichi and 27 cm in Woodstock.

Deep snow cover across N.B.

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.

Spring-like in Eastern Canada

Ahead of a Colorado Low, a mild southerly air flow moved across Eastern Canada resulting in record high temperatures from Southern Ontario to New Brunswick.

Bitter cold ahead of more snow

Temperatures sunk early Monday across the Maritimes with some New Brunswick locations shattering records by almost five degrees dating back to the 1880’s.

The bitter cold precedes another storm system which could bring up to 25 cm of snow to southern New Brunswick, most of Prince Edward Island and northern Nova Scotia.

While it plunged to -14.7°C in Greater Moncton, the 1936 record still stands at -16.7°C.

Here are some of the new record lows set in the region on 19 November:

  • Bathurst, NB -22.5°C
  • Woodstock, NB -21.4°C
  • Miramichi, NB -20.2°C
  • Kouchibouguac, NB -20.0°C
  • Summerside, PE -15.7°C
  • Charlottetown, PE -15.2°C

Nor’easter follows record cold

Snow settles in NE Moncton before a changeover to rain, 28 Oct 2018 (Dearing)

A frosty Saturday morning proved record breaking at the Greater Moncton International Airport when the thermometer plunged to -6.6°C which breaks the previous cold low from 1998 by 0.1°C.

Frigid temperatures were also set in Edmundston at -12.2°C, Woodstock at -11.7°C and Saint John at -8.4°C with weather records going back to 1886.

The Arctic cold was soon replaced by a low pressure system with some tropical moisture from the remnants of Hurricane Willa.

The early season Nor’easter brought snow, ice pellets and eventually rain to the Maritimes along with gusty winds which uprooted trees in parts of New England.

Say it isn’t snow!

Snow settles on grass, vehicles and rooftops in NE Moncton, 25 Oct 2018 (Dearing)

Even by New Brunswick standards, snow in October is not very common.

But a low pressure system dropped more than 15 cm of heavy, wet snow over western and northern parts of the province creating commuter chaos in Fredericton yesterday.

After getting drenched with 38 mm of rain, Greater Moncton received a light coating of snow this morning which stuck to rooftops, vehicles and grassy areas but it melted by midday.

Here are some snowfall totals (in cm) from volunteer observations:

  • Charlo/Belledune area. 23 cm
  • Woodstock. 16 cm
  • Fredericton. 15 cm
  • Miramichi. 13 cm
  • Grand Falls. 10 cm
  • Moncton. 3.4 cm

A chilly start!

It may have been the warmest summer in the Maritimes in almost a century but some parts of the region woke up to below freezing temperatures and frost this morning!

That means some areas had a growing season which barely lasted 100 days since the last spring frost for many was 04 June.

Greater Moncton was definitely chilly with an early morning low of 3.0°C which was close to the record low of 1.1°C from 1956.

Here are some of the nippy overnight lows:

  • Edmundston, NB  -2.0°C
  • Woodstock, NB  -0.8°C
  • Red Pines, NB  -0.7°C
  • Fredericton, NB  0.1°C
  • Upper Stewiacke, NS  -0.4°C
  • Maple Plains, PEI  1.4°C

Western NB gets drenched

A slow moving frontal system brought heavy rain to western New Brunswick with about 20 mm falling per hour in the southwest.

Environment Canada reported 174 mm of rain in St. Stephen over a two day period which is a shocking amount considering about 180 mm fell from June to September.

Other amounts include 112 mm in Edmundston, 93 mm in Woodstock and 74 mm in Fredericton.

Rainfall totals were much lower in Southeast New Brunswick where only 27 mm fell at the Greater Moncton International Airport.

Tropical air with this system broke more record highs in Atlantic Canada with a maximum of 23.4 C in Moncton and Bouctouche, 23.5 C in Cheticamp, 22.0 C in Deer Lake and 21.2 C in Happy Valley-Goose Bay.
