The skyline of Moncton, NB, 16 Sept 2018 (Dearing)
An abrupt change in temperature thanks to a passing cold front turned summer quickly into fall in Greater Moncton this week.
On Tuesday, Environment Canada reports a temperature of 22°C at 11am which plummeted to 16°C by 1pm and the wind direction changed from the southeast to the northwest.
The long, hot summer in New Brunswick was suddenly over.
The daytime high on Wednesday was 13.6°C which was the coolest day since 25 June.
Forecasters are calling for near or slightly below seasonal temperatures until the end of the month (Normal high 18°C, normal low 7°C).
While a snowflake or two is common in early May in New Brunswick, accumulating snow is rare in the latter part of the month.
A cold front pushed through the province today and with a change in wind direction from south to north, precipitation changed from rain to snow and the thermometer plummeted.
Bathurst and Miramichi both reported snow today and in some areas it began to stick to the ground while thunderstorms rolled through further south.
In Greater Moncton, the temperature drop was dramatic with a high of 16 C at 11am and by 4pm it was only 5 C.
Meantime, parts of central Newfoundland are under a snowfall warning with 15 to 30 cm in the forecast.
The Weather Network has taken a look ahead at the months of March, April and May for Atlantic Canada…
While it has been a relatively mild winter across the region, winter will still have several parting shots, including the threat for a few Nor’easters.
For some places, the biggest snowfall of the year could still be on the horizon (keep in mind the context – some areas have not had a classic winter storm).
Back and forth temperature swings should come close to offsetting, but with more potential for warmth to outweigh the periods of colder weather.
An active storm track will tap into subtropical moisture at times and bring above normal precipitation to most of the region through the spring season.
The beaches of Varadero, Cuba, 15 February 2018 (Dearing)
Let’s face it, winter in Southeast New Brunswick has been a volatile roller coaster ride with wildly fluctuating temperatures and unusual amounts of mixed precipitation.
I wanted an escape, so a two-week vacation getaway to Cuba was in order.
From 06-20 February, the island’s most popular beach destination of Varadero enjoyed daytime highs in the upper 20s C with glorious sunshine and just a few passing clouds.
Winter is the dry season in Cuba and precipitation was light except for a lengthy downpour of rain during just one early morning.
Varadero has some of the best beaches in the Caribbean and millions of international visitors – mostly Canadians – flock there every year.

Snow falls in Denver, Colorado, USA, 09 April 2013 (AP)
A dynamic storm system has produced a blizzard, severe storms with large hail and crazy temperature swings from North Dakota to Texas.
Heavy snow fell in many areas with the U.S. National Weather Service recording snowfall records being broken in 44 cities with some parts of Nebraska receiving as much as 60 cm.
A dramatic drop in temperature also occurred with Abilene, Texas falling from a scorching 33 C to near freezing in less than 8 hours from last night to early today.
The same storm system is moving into Ontario tomorrow and is expected to bring heavy rain and snow.
