Fall sneak preview

Bouctouche Dunes, NB, 06 Sept 2020 (Dearing)

For the first time since mid-July, the daytime high in Greater Moncton didn’t reach 20°C.

On Friday, the daily maximum was 15.5°C which is also about five degrees below normal for mid-September.

The fall-like weather arrived after a cold front moved across New Brunswick replacing warm, humid air with cooler, drier conditions.

This morning’s chilly low of 4.0°C was the coldest since 10 June when the temperature fell slightly below freezing – enough for a light frost.

While some parts of the province had scattered frost, my neighbourhood and my tomatoes were spared.

August 2020 – The heat continues

A stretch of warm, dry weather which started in mid-July continued through August in Greater Moncton.

Daytime highs climbed above 30°C on 11 days which is well above the average of 5 days during an entire summer.

Cooler conditions prevailed during the last few days of the month after a thunderstorm rolled through New Brunswick.

Rain was once again scarce – only two major events – which only worsened the severe drought across the region.

Warm summer-like weather continued throughout July after finally getting started in mid-June across New Brunswick.

Several heat warnings were issued with daytime highs reaching 30°C or more on eight days – the normal is two.

The overall average may have been even higher for Greater Moncton had it not been for cool overnight lows early in the month.

July 2020 still falls a bit short of the very warm July 2018 which reached 21.4°C.

The drought worsened and although rainfall was higher compared to June it was still 25 percent below normal.

Brutal heat in Death Valley

California’s Death Valley National Park is one of the hottest places in the world – and the last few days have been no exception.

A scorching high of 53.2°C or 127.7°F was recorded on Sunday which was the highest temperature on the planet since 2017.

A prolonged heat wave has been baking the American Southwest with highs well into the 40s Celsius (over 100°F) in major cities like Phoenix, Las Vegas and Dallas.

Forecasters say the excessive heat is moving across the continent and will arrive in the U.S. Northeast by this weekend.

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

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.

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.

March 2020 – Warm and dry

Irishtown Reservoir, Moncton, 15 March 2020 (Dearing)

Much less rain and snow fell in Greater Moncton during March even though precipitation was recorded on 23 days.

Only 10 mm of rain and 32 cm of snow fell with the normals being 49 mm and 65 cm respectively.

Warm daytime highs were scarce – the thermometer failed to reach 10°C – but temperatures were actually slightly above average overall.

The coldest weather occurred during the first few days of spring with a minimum of -13.8°C on 23 March.

Spring-like weather ends

The last few days have felt like spring in New Brunswick but the warm spell is about to end.

Temperatures have soared as high as 10°C in some areas.

The normal maximum for late February is about 0°C in Greater Moncton.

Recent daytime highs:

  • 6.1°C on 23 Feb
  • 7.3°C on 24 Feb
  • 6.0°C on 25 Feb
  • 4.0°C on 26 Feb

However, winter is returning as a low pressure system brings mixed precipitation to Ontario and Quebec with the Maritimes next in its path.

Environment Canada has issued various weather warnings and up to 25 cm of snow and ice pellets could fall starting late Thursday into Friday.
