Snow falling in west end Moncton, 10 Nov 2017 (Dearing)

A low pressure system moved into New Brunswick today bringing heavy rain accompanied by a vigorous cold front with Arctic air behind it.

As a result, the temperature in Greater Moncton plunged dramatically in just one hour – from a daytime high of 10.3 C at 11am to only 1.8 C by noon.

The thermometer continued to drop below freezing and rain turned to snow before the sky cleared in the late afternoon.

Environment Canada is forecasting a cold but dry weekend with sunshine and temperatures at or slightly above freezing.

Dramatic drop in temperature

Autumn has made an abrupt return to Southeast New Brunswick.

The passage of a cold front lowered daytime highs in Greater Moncton from a near record of 19.3 C to a below seasonal high of 5.2 C over the past 24 hours.

Temperatures are poised to drop even lower later this week when the first blast of Arctic air this season moves into the Maritimes.

Environment Canada is forecasting a low of -7 C by early Saturday which will likely mean a hard, killing frost for any remaining sensitive vegetation.

October 2017 – Second warmest since 1881

October often felt like August in Greater Moncton with 12 days reaching daytime highs of 20 C or higher.

Environment Canada says only October 1913 was slightly warmer since records began in 1881.

Temperatures did fall below freezing on 7 days with some scattered frost but the month escaped a hard frost and vegetation continued to flourish.

Rainfall was more than 30 percent below normal in Southeast New Brunswick continuing a prolonged dry period which began in early summer.

September turned out to be a continuation of summer in Southeast New Brunswick right up until month end.

Daytime highs in Greater Moncton climbed above 25 C on ten days and a monthly maximum of 31.1 C turned out to be the warmest of 2017 set in early fall (26 Sept).

Although hurricanes never directly affected the province, meteorologists say much of the warmth last month came from tropical air pushed northward from these storms.

Rainfall was exactly normal but almost all of the precipitation fell during a single rain event spread over two days (6-7 Sept).

The dry summer in Southeast New Brunswick continued in August with a dangerous forest fire hazard and little precipitation to soak the parched ground.

A dry trend which began in late June continued during the month with less than 50 mm of rain falling in Greater Moncton.

Temperatures were above normal with daytime highs consistently in the high 20’s Celsius but a string of single digit overnight lows during the final week brought down the overall monthly average.

July 2017 – Warm and dry

As the month of July progressed in Southeast New Brunswick, lawns turned brown and forests became extremely dry as temperatures soared and little rain fell.

Greater Moncton only received one-third of its normal monthly rainfall and 15 days had no precipitation at all.

The heat was steady throughout July with 20 days reaching 25 C or higher and four days climbing to 30 C or more.

A brief cool down near month end lowered daytime highs to the low 20s Celsius and brought a chilly overnight low of 6.9 C.

Unusual mid-summer cool snap

Late July is typically the warmest period of summer in Greater Moncton but a recent cool down has brought September-like days and a record overnight low. 

On 23 July, the temperature fell to 6.9 C at the Greater Moncton International Airport which broke a record low of 7.2 C from 1962. 

A frost advisory was posted in northwest New Brunswick with a chilly low of 2.4 C in Edmundston. 

The short term forecast calls for more seasonal highs in the mid-20’s C and lows near 13 C. 

Heat wave abruptly ends in N.B.

Heavy rain during thunderstorm in NE Moncton, 21 July 2017 (Dearing)


The temperature climbed to 30 C for three days in a row in Greater Moncton which is an unofficial heat wave since 32 C is the maximum by definition.

Those warm daytime highs, 30.4 C (19 July), 30.4 C (20 July) and 30.0 C (21 July), still haven’t eclipsed the season-to-date maximum of 30.8 C recorded on 11 June.

A cold front moved west to east through New Brunswick yesterday triggering scattered thunderstorms with heavy rain, gusty winds and even hail.

The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

Decent first half of July

For whatever reason, summer seems to go by faster than the other seasons and here we are already at the midway point of July. 

After 16 days, Greater Moncton has been having a decent month with an average temperature of 19.3 C which is 0.5 degrees above normal. 

Daytime highs have been warm but not hot with a peak of 29.4 C on 16 July while overnight lows have been mild except for a chilly low of 8.9 C on  05 July. 

The only concern is a lack of rainfall. 

The tally is 19.8 mm so far – less than a quarter of the monthly total – but keep in mind we are entering what is traditionally the driest period of the year in Southeast New Brunswick.

Thunderstorm activity was common throughout Southeast New Brunswick in June and all but ten days had at least a trace of rainfall.

But precipitation amounts were generally light in Greater Moncton except for two major rain events – 36.6 mm fell on 09 June along with a peak wind gust of 102 km/h and 21.2 mm fell on 24 June.

Temperatures were cool during the first week of the month with an overnight low dropping to the freezing point although frost was generally avoided thanks to cloudy skies.

Summer-like conditions arrived by mid-month and many daytime highs climbed well into the 20’s C and reached 30 C or higher three times.
