A cold front moved across New Brunswick on Thursday bringing thunderstorms with much needed rain and ushering out the heat and high humidity.

The temperature climbed to 30°C in Greater Moncton during the noon hour but dropped to 22°C by 2pm and 17°C by 6pm.

A severe thunderstorm watch was posted for a couple hours and 16 mm of rain fell which was good news considering the current drought conditions.

The last decent rainfall was on 12 June when 21 mm fell.

Environment Canada is forecasting possible showers or thundershowers this weekend.

May 2020 – Cool and dry

For the last few years, the month of May in Southeast New Brunswick has been colder than normal and this year was no exception.

A new record high was set during a mini heat wave at month’s end which was enough to boost temperatures to just slightly below average.

Snow fell as late as the 12th and rain was scant which led to a dry month overall.

Frost was recorded on the 24th which is close to the last average date in Greater Moncton – if it turns out to the last frost of spring.

Snow pellets!

Snow pellets or graupel fall in NE Moncton, 22 April 2020 (Dearing)

Many areas of New Brunswick reported intervals of snow pellets mixed with snow on Wednesday including Greater Moncton.

Also known as graupel, snow pellets are tiny super-cooled water droplets which collect on a snowflake and fall to the ground.

Meteorologists say it’s not unusual to see graupel in the spring on cool, unstable days.

Coolest day since May

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.

June 2019 – Mild and wet

The average monthly temperature for June in Greater Moncton was at least close to normal compared to a damp, cold May.

While daytime highs climbed to 20°C or higher on 20 days, significant heat was scarce and the thermometer didn’t even get close to 30°C.

Rainfall was heavier than normal – a measurable amount was recorded on 21 days – following a trend which began in early spring.

About three-quarters of the precipitation fell during the last ten days of the month.

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.

When will it reach 30°C?

First 30
It’s been a cold spring in Greater Moncton and the thermometer didn’t reach 20°C until 25 May – so when will it hit 30°C?

According to Environment Canada, the average date since 2013 has ranged from mid-May to late June but mainly late May.

While June has been warmer to date in Southeast New Brunswick, the long range forecast is calling for cooler conditions.

Will we have to wait until July this year?

April 2019 – Wet and chilly

Spring can be the most disappointing season of the year in New Brunswick and April 2019 was no exception with cloudy, cool and often wet conditions.

Surprisingly, Greater Moncton was close to normal in temperature but double the average amount of rain fell along with slightly more snow than usual.

Melting snow and heavy precipitation led to more disastrous flooding along the St. John River – almost as bad as last year’s historic water levels.

Only one day was fully below freezing and while nights weren’t that cold, daytime highs often struggled to reach the double digits.
