It felt more like mid-spring than late winter across Southern Ontario today.
A mild air mass combined with strengthening February sunshine to set new record highs in the region.
Environment Canada reports April-like maximums for 28 February:
- Sarnia, 16.8 C, old record 15.1 C from 2016
- Toronto Pearson Airport, 16.2 C, old record 14.0 C from 2016
- Windsor, 16.1 C, old record 13.6 C from 2017
- London, 15.1 C, old record 14.2 C from 2016
- Kitchener-Waterloo, 15.0 C, old record 12.4 C from 2016
Powerful storm surge causes flooding along the waterfront in Halifax, NS, 05 Jan 2018 (Twitter)
The ‘bomb cyclone’ or ‘snow hurricane’ – featuring a dramatic drop in atmospheric pressure when warm and cold air collided – has left the Maritimes and spared Southeast New Brunswick from the worst of its fury.
While strong winds were a factor throughout the region, Greater Moncton received less snow compared to further north and west.
To the south and east, more rain fell along with hurricane-force winds (up to 200 km/h gusts in western Cape Breton) which created powerful storm surges causing flooding along the coast.
Here are some totals from Environment Canada and local estimates:
- Greater Moncton Airport 14 cm snow, 10 mm rain, 91 km/h wind gust
- Bathurst 58 cm snow, 80 km/h wind gust
- Fredericton 30 cm snow, 78 km/h wind gust
- Saint John 5 cm snow, 20 mm rain, 87 km/h wind gust
- Halifax Stanfield Airport 40 mm rain, trace snow, 122 km/h wind gust
The storm may have departed but Arctic air has filtered back into the Maritimes which will mean a bitterly cold weekend.
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.
Heavy snow falling in northeast Moncton, 09 Dec 2017 (Dearing)
A classic snowstorm brought heavy, moisture-laden snow to much of New Brunswick this weekend.
Environment Canada says the heaviest amounts fell in northeast areas of the province with 27 cm at Bathurst and 24 cm at Miscou Island.
Greater Moncton received 15 cm which was exactly what was being forecasted for Southeast New Brunswick.
The same system brought rain and warm temperatures to eastern mainland Nova Scotia, Cape Breton and the island of Newfoundland with a high of 18 C in St. John’s.
Many trees are losing leaves in west end Moncton, 27 Oct 2017 (Dearing)
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.

Along the Riverfront Trail in Moncton, 21 October 2017 (Dearing)
Nine communities across New Brunswick set new record highs yesterday and the same will likely happen again today.
Greater Moncton was the warmest spot in the province climbing to 23.1 C which broke the old maximum temperature of 22.8 C from 1928.
Greenwood was among six communities in Nova Scotia breaking records with a high of 24.5 C.
Four records fell on Prince Edward Island including Charlottetown at 21.7 C.
Environment Canada says the Maritimes is enjoying a late October heat wave because the region is sandwiched between low pressure and high pressure allowing warm, southerly air to move northward.
Maple tree past peak in Moncton, 22 Oct 2017 (Dearing)
The fall foliage in Southeast New Brunswick is now past peak and the leaves are starting to tumble to the ground.
Typically a strong wind and/or rain event will bring down most remaining leaves from the trees with maples the first to shed and oaks among the last.
Forestry experts say unseasonably warm weather across the Maritimes this autumn have muted some fall colours.
Rich, vivid displays are most common when days are sunny but cool and nights are cold.
Aboiteau Beach, Cap-Pele, NB, 08 Oct 2017 (Dearing)
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.
Maple leaves changing colour in Fairview Knoll Park, Moncton, 04 Sept 2017 (Dearing)
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).
