Spring was mostly absent during the first two-thirds of April in Greater Moncton with daytime highs often barely above freezing and overnight lows which were much colder than normal.

Suddenly spring arrived during the last third of the month when temperatures jumped to 20 C and higher by day and above freezing by night.

While more rain fell during April compared to average, snowfall was scant which led to below normal precipitation overall.

The seasonal snow cover finally melted by mid-month but it had disappeared twice (late January and early March) since mid-December.

Meteorological winter 2017/18 is now in the books since the three month period of December, January and February is over but we all know winter is not over yet in Southeast New Brunswick.

What a ride it has been in Greater Moncton with temperatures fluctuating wildly from very mild to extremely cold in just hours and in one case in mere minutes.

Snowfall was lighter compared to normal especially in February but the bigger concern were frequent periods of mixed, icy precipitation such as freezing rain and ice pellets.

TWN unveils spring forecast

TWN spring

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.

Canada had the eighth warmest period in 70 years of reporting weather in 2017, with temperatures averaging 1.4°C above normal.

From a list of 100 significant weather events across the country, Environment Canada picked the top 10 weather stories of the year:

1. Long and destructive summer wildfire season in British Columbia

2. Hot and dry summer in the West from Interior BC to Manitoba

3. Spring flooding in Quebec and Ontario

4. Cold and snowy winter in BC including Lower Mainland and Vancouver Island

5. More heavy rain and flooding in Southwestern Ontario during late August

6. Cool and wet summer in Central Canada

7. Heavy snow cripples Ontario and Quebec in mid-March

8. Record heat across Eastern Canada during September

9. Blizzards hit Newfoundland in March and April

10. Lengthy ice storm impacts New Brunswick in late January

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.

As dark and dreary as November seems in Southeast New Brunswick, temperatures can often be volatile and this month was no exception.

Greater Moncton had at least five dramatic temperature swings starting on 10-11 November with a high of 10 C falling to -7 C with strong winds gusting up 69 km/h and the first snow flurries of the season.

The monthly mean of 1.9 C was exactly normal with highs near 20 C on two days early in the month while two days remained below freezing.

Overall precipitation was near normal for the first time since May although snowfall at 3.2 cm was well below normal.

Fall foliage past peak

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.

May 2017 – Wet and cloudy

May in Southeast New Brunswick certainly lived up to its unpredictable nature as a transitional month between winter and summer.

Overall temperatures were above normal in Greater Moncton but oddly enough some of the coolest days were in the last third of the month.

Many days were cloudy and rainfall was heavy with only seven days without at least a trace of precipitation.

By the final week, trees were in full leaf or blossom and perennials were in full bloom.

Three major winter storms including a blizzard were part of a very active weather pattern in Greater Moncton during February.

While snowfall was below normal in January, it made up for it in February with more than double the average amount recorded.

Temperatures were above normal but oddly enough it was still warmer in January which is typically the coldest month.

The final week felt like spring with mild temperatures climbing above 10 C which was enough to melt most of the snow which had fallen during the previous three weeks.
