Record highs in Alberta

Residents of Alberta were golfing rather than skiing this weekend as chinook-like weather brought record high temperatures.

On 09 December, Calgary set a new record of 15.4 C which broke the old record by one full degree from 1890.

The normal daytime high for Calgary is -1 C with an overnight low of -13 C.

Other records were set in Claresholm which hit a summer-like 20.3 C while Sundre reached 16.3 C.

Environment Canada says double digit highs are likely for at least the next few days.

Meteorological winter begins

EC winter

Most Canadians know winter, astronomically speaking, begins around 21 December but we know the season actually gets underway weeks before then.

Meteorologists like to package winter into neat three month blocks which is why 01 December marks the start of meteorological winter and 28 February marks the end.

In its three month outlook, Environment Canada expects most of New Brunswick will have above normal temperatures and near normal precipitation.

A large swath of the Arctic will likely be warmer than usual while Ontario and the southern Prairies will have higher amounts of rain and snow compared to normal.

Clear skies and an Arctic air mass lowered temperatures in Greater Moncton to a chilly -9.0 C on November 12th and 13th.

Recent data shows temperatures that low (within 2 and 3 degrees of record lows) typically don’t occur until later in the month and the thermometer failed to climb above freezing on the 12th which is also earlier than normal.

A new record low was set at the Saint John Airport when it fell to -11.3 C on the 12th.

Quite a contrast from just a week ago when several communities in New Brunswick climbed into the low 20s Celsius.

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.

Record highs across Maritimes

A warm southerly flow allowed temperatures in the Maritimes to climb into the low 20s C yesterday with record highs broken in all three provinces. 

Bouctouche was the hot spot in New Brunswick at 21.1 C which was the same record high set at St. Peters, Prince Edward Island. 

Greenwood, Nova Scotia reached a summer-like maximum of 25.5 C which was the warmest in Canada. 

A new high was also set at the Greater Moncton International Airport at 19.7 C edging out a record from 1999. 

After a cold front moved through the region with some much needed rain, temperatures fell back to more seasonal values. 

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.

Warm Thanksgiving weekend

The jet stream brought warm southerly air into the Maritimes allowing temperatures in Southeast New Brunswick to climb into the 20s this Thanksgiving weekend.

Environment Canada says Greater Moncton reached a daytime high of 20.2 C on 07 October, 23.7 C on 08 October (near the record of 23.9 C from 1970), and 22.9 C on 09 October.

Given the autumn warmth, I couldn’t resist a visit to Aboiteau Beach (and neither could a handful of others) which was near 24 C under a mostly cloudy sky and it was quite windy.

Greenwood, Nova Scotia was the hot spot in Canada hitting 26 C for two days in a row.

Patchy frost!

Perhaps it’s fitting that October has begun with patchy frost in Greater Moncton given that autumn weather arrived abruptly just days ago following a stretch of hot summerlike conditions.

Environment Canada had issued a frost advisory for three nights running (and another one has been issued tonight) for Southeast New Brunswick but frost finally made an appearance early today when the thermometer dropped to -1.0 C.

Fortunately, the flower boxes on my balcony were not affected and I brought my tomato plant inside just in case.

The last time the temperature fell below freezing in Greater Moncton was 06 June which means 116 days were consecutively above freezing in 2017. 

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.

Meteorological Summer in Greater Moncton

If you were looking for great summer weather in the province, Environment Canada says Greater Moncton and Southeast New Brunswick was the place to find it this year. 

The average temperature for meteorological summer – June, July and August – was 18.1 C which is 0.7 degrees above normal. 

The weather office says humidity was often low, overnight lows were comfortable but 8 days hit 30 C or higher compared to a typical 4 to 5. 

The downside was a lack of precipitation with 155 mm of rain recorded which is 40 percent less than the summer average of 268 mm.
