New record highs set in NB

Jones Lake, Moncton, NB, 28 May 2015 (Dearing)

It turned out to be a scorcher of a day in most of New Brunswick yesterday.

Environment Canada says nine communities set new record highs.

In Greater Moncton, the thermometer climbed to 31.5°C at the airport which beats the old area record of 30.6°C from 1929.

By mid-afternoon, the humidex had reached an unbearable 50 in Miramichi before the humidity level finally dropped.

The highest temperature in the province and all of Canada was Red Pines near Bathurst at 36.0°C.

Meanwhile, fog kept temperatures much cooler along the Fundy coast with a high of only 15°C in Saint John.

From cold to hot

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

River Watch ends

The annual River Watch in New Brunswick has ended for the 2020 season.

The program was launched in early March and monitors water levels on rivers in the spring with emergency officials providing regular updates on the potential for flooding.

After historic flooding along the St. John River in both 2018 and 2019, thankfully this spring was much quieter with no major events recorded.

It’s a blessing in disguise since the province has been coping with the coronavirus pandemic with a state of emergency in place since 19 March.

Finally 20°C!

First 20

The thermometer finally hit 20°C in Greater Moncton – a benchmark not seen since 26 September (almost eight months!) – and it comes much later compared to recent years.

The temperature reached 20.3°C late this afternoon although Fredericton was the hot spot in New Brunswick at 21.7°C.

It has been an exceptionally cold spring – May is running about four degrees below average to date – and even slightly colder than last year’s chilly season.

Environment Canada is forecasting another cool start to the week but a warming trend could push daytime highs to almost 30°C by Friday.

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

Warmest day since December

Greater Moncton climbed to a daytime high of 13.4°C on 14 April which was the warmest in four months – since 15 December.

During the last few years, the thermometer has typically been surging into the teens Celsius by mid-April.

Environment Canada data shows the next heat milestone in Southeast New Brunswick, 20°C, is typically reached between now and early May although that kind of warmth is not in the current long range forecast.

In 2019, the milestone was reached on 05 May when it hit 19.7°C.

Spring 2020 forecast unveiled

Spring 2020
The Weather Network has unveiled its spring forecast for the months of March, April and May.

Recent spring-like weather in New Brunswick has made many wonder when the real season will arrive.

TWN meteorologist Doug Gilham expects we should still expect some wintry weather during March which is not unusual but he thinks temperatures should be near normal for the three month period.

Gilham believes it will be a wet season overall with above normal precipitation especially rainfall.

Last year, spring was very late and cold weather just wouldn’t let go.

Snow was recorded as late as 21 May in Greater Moncton.

Coolest day since May

Irishtown Nature Park, 05 October 2019 (Dearing)

Chilly temperatures across the Maritimes on Friday made it feel more like early November than early October.

In Greater Moncton, the daytime high for 04 October was only 8.2 C which means it was the coolest day since 22 May when the maximum was only 8.6 C.

Halifax, Charlottetown, Saint John and Fredericton also had highs below 10 C.

The normal high for the first week of October in Southeast New Brunswick is 15 C with an overnight low of 4 C.
