Harvest Moon

The almost Full Harvest Moon over Moncton, NB, 04 Oct 2017

Under a mostly cloudy sky, it was difficult to capture the Full Harvest Moon in most of Southeast New Brunswick but I did manage to get a shot last night.

The Harvest Moon derives its name from when farmers used the moon’s bright light to help them gather crops for winter.

The Harvest Moon is the full moon nearest to the autumnal equinox which occurred on 22 September.

September 2017 – Summer continues

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).

Warmest high of 2017

Having a heat wave in late September is unusual for Southeast New Brunswick but even more so is that the highest temperature of 2017 has occurred in early autumn.

The thermometer soared to 31.1 C yesterday (26 September) at the Greater Moncton International Airport which breaks the previous maximum of 29.6 C from 2007 and records date back to 1881.

The previous high for the year had been 30.6 C recorded on 04 August.

At least 10 other New Brunswick communities set new record highs yesterday including Fredericton at 32.8 C, Woodstock at 32.3 C and Bouctouche at 31.8 C.

Environment Canada says temperatures will return to more seasonable values by the weekend with highs between 16 and 18 C.

Early fall heat

This may have been the first weekend of autumn in Southeast New Brunswick but it felt more like the first weekend of summer instead.

Greater Moncton climbed to 27.7 C yesterday (23 September) while today (24 September) it hit 27.9 C and the normal high for late September is 17 C.

High pressure and a northerly jet stream has pushed heat across Eastern Canada with highs in the low 30s C in many parts of Ontario and Southern Quebec.

A heat warning was in place as Toronto Pearson Airport reached a record-breaking 33.1 C yesterday and 33.6 C today.

September heat

September usually doesn’t disappoint in Southeast New Brunswick when it comes to warm weather and so far this month is no exception.

Environment Canada reports on 14 September, the thermometer climbed to 27.8 C in Greater Moncton which ties the record high from 2003.

St. Stephen was the hot spot in the province and all of Canada with a high of 29.2 C which eclipsed the old record from 1903.

As we approach the first day of autumn on 22 September, temperatures in Greater Moncton can still climb into the 30s Celsius with a record high of 32.8 C in 1965.

Record heat in California

San Francisco rarely suffers from hot weather which is why many residents are struggling to stay cool during a heat wave since most homes don’t have air conditioners.

The U.S. National Weather Service says the thermometer climbed to an all-time record-breaking 41.1 C (106 F) on 01 September and another record of 38.9 C (102 F) was set the following day.

Those sizzling highs are a far cry from the average of 21 C for the northern California city.

Numerous wildfires in the region have produced smoke and haze which has added to air quality concerns.

The heat has also stretched northward to Oregon, Washington State and British Columbia where temperatures could exceed 30 C on Vancouver Island.

Brisk start to September

Astronomical summer may be officially over but no one expects to see snow at the start of September after a cold front pushed Arctic air southward across Eastern Canada.

With temperatures near freezing, several centimetres of snow fell in northeastern Quebec and Labrador West overnight and drivers say the roads quickly became slushy and slippery.

Greater Moncton felt autumn-like with strong gusty winds under a mostly cloudy sky and temperatures struggled to reach the high teens Celsius.

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.

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.
