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.

From the horrible wildfires which destroyed parts of Fort McMurray, Alberta to the winter that wasn’t to a warm, dry summer which led to drought in areas of Eastern Canada, 2016 was certainly noteworthy for major weather events.

Heavy rain hits SW Ontario

Upwards of two months worth of rain has fallen in just a few days in a corner of Southwestern Ontario which includes Windsor and Tecumseh.

The normal September rainfall in the region is just under 100 mm with as much as 195 mm falling in some areas this week prompting a state of emergency.

Environment Canada says a strong and slow moving low pressure system brought heavy rain which led to flooding.

More than 1,500 Windsor residents reported basement flooding and many streets were inundated with water leaving vehicles stuck.

Warm September expected in N.B.

The warmth of summer is expected to continue well into September in Southeast New Brunswick according to Environment Canada.

Meteorologists say the waters surrounding the Maritimes (Bay of Fundy, Atlantic Ocean, Northumberland Strait and Gulf of St.Lawrence) are about 2-3 Celsius above normal for this time of year.

Warm water generates energy which will help elevate temperatures throughout the region.

Precipitation is difficult to predict at this time of year since remnants of a post-tropical storm could easily deliver a hefty rainfall in just a few hours.

Starting to feel like fall

September was really a continuation of summer in Southeast New Brunswick but this weekend felt like fall for the first time with cold nights and scattered frost.

Greater Moncton fell below freezing this morning dipping to -0.7 C which is the coldest overnight low since 07 May.

The growing season is essentially over now with more possibilities of frost in the week ahead.

But given warm, dry weather in August and September, Environment Canada says the leaves are behind schedule by at least a week or two in displaying their brilliant hues of red, orange and gold.

A month’s worth of rain expected

A cold front from Quebec has combined with a strong tropical-like system from the U.S. Eastern Seaboard over the Maritimes bringing a month’s worth of rain to some areas.

Environment Canada is forecasting up to 100 mm for Greater Moncton by Thursday morning with even higher amounts for Saint John and Fredericton.

September has been dry in Southeast New Brunswick and just two major rain events – this one and on the 11th – contributed to nearly all of the month’s precipitation.

A 100-year-old record high was broken today in Moncton according to Environment Canada.

On this date in 1915, the thermometer climbed to 27.8 C but today that high was surpassed with a new record of 29.0 C.

Bathurst, Miramichi and Kouchibouguac all climbed to at least 30.0 C.

Fredericton was the hotspot in New Brunswick and the entire country today at 30.2 C.

Temperatures are running almost 10 degrees above normal for mid-September.

Subtle hints of autumn

It’s often hard for me to let summer go…

This year is no exception but fortunately warm weather is continuing in Southeast New Brunswick.

If you look around, subtle hints of autumn are starting to appear with some leaves changing colour and a few already drifting to the ground.

Greater Moncton continues to lose daylight at a fast pace during early September – we have lost almost 30 minutes in the past 10 days.

The Weather Network unveils fall forecast

Although it still feels like summer in New Brunswick, meteorological autumn has arrived and The Weather Network has released its seasonal forecast.

The El Nino weather phenomenon in the Pacific is expected to lessen the impact of tropical storms in the Atlantic this fall.

Forecasters say temperatures will remain warm throughout September, normal in October but a pattern change is in store for early November.

However, a brief winter-like chill will be short-lived and more seasonal weather is in store for the remainder of this year.

A burst of autumn colours have appeared in Southeast New Brunswick over the past week and judging by the show so far we could be in for a beautiful fall season.

The average monthly temperature in September for Greater Moncton was almost 1°C above the 30-year average thanks to warm, daytime highs and comfortable overnight lows.

The maximum temperature exceeded 25°C on eight days during the month.

Although it dipped close to freezing on 19 September, frost was not recorded during the month and many flowers and plants continue to flourish.

Rainfall was below normal with the only noteworthy rain event on 21-22 September which turned out to be an almost hurricane-like storm.
