Despite chilly weather, snowbanks are melting in NE Moncton, 16 April 2018 (Dearing)
Mid-April is here already but temperatures certainly haven’t been improving very much lately in New Brunswick.
Overnight lows continue to be abnormally cold with records set on Sunday, 15 April.
Greater Moncton fell to -9.1 C which breaks a record low of -8.6 C from 1981.
New records were also set in Bouctouche at -8.6 C and Miscou Island at -9.3 C.

Since the start of astronomical spring, the highest temperature in Greater Moncton has been 9.1 C and overnight lows have dropped to a near record low of -8.8 C.
So many are asking when is it ever going to warm up in New Brunswick?
The Maritimes has recently found itself on the north side of the prevailing jet stream which has allowed cold, Arctic air to sink south.
Environment Canada says the temperature should finally climb to at least 10 C by Friday.
Keep in mind, the first 20 C reading of the season was 12 April in 2017 while it was 21 April in 2016.

An intense low pressure system off the Atlantic coast of Nova Scotia brushed the eastern portion of the province and Cape Breton Island with heavy snow.
New Brunswick, northern Nova Scotia and Prince Edward Island were spared from this storm.
The eastern part of Cape Breton was the hardest hit with almost 35 cm of snow recorded in the Sydney area.
Here are snowfall totals as of 9am ADT, 09 April (in cm):
- Sydney 34.6
- Cheticamp 22
- Halifax Stanfield Airport 23.4
- Dartmouth 14
- Bedford 10
Winter just won’t let go in Western Canada with Environment Canada noting the duration and intensity of the current cold snap hasn’t been felt since April 1970.
The polar vortex is to blame as the pool of Arctic air sinks south into the Prairies.
Daytime highs in southern Alberta are only climbing to -7 C with overnight lows in the -20’s C in Saskatchewan and -30’s C in Manitoba.
Forecasters say the bitter cold will hang around until the weekend.
Another long and dark winter is finally over – at least astronomically speaking anyway!
The vernal equinox officially arrived at 1:15pm ADT in New Brunswick marking spring as the length of day equals the length of night.
But forecasters say winter weather is not over yet with the fourth Nor’easter in two weeks expected to hit the Maritimes on Thursday.
Environment Canada says spring-like weather may not arrive until month’s end or early April.
So much for Shubenacadie Sam’s prediction of an early spring!
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
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.

Spring seldom arrives on time in New Brunswick and this year is no exception even though April was actually warmer than normal in Greater Moncton.
The month can be broken into four segments – cold in the beginning, then warm, turning cold again and finally warm again near the end.
A consistent snow cover began on 27 November and disappeared briefly in late January before finally melting for the season by 10 April.
Precipitation overall was below average with much less snow than normal.

Arctic air has enveloped the United Kingdom with heavy snow in Scotland and northern England and near freezing temperatures as far south as London.
Forecasters say snow in late April is not uncommon and actually fell over parts of the country around the same time last year.
Temperatures struggled to reach 10 C today after a hard frost early this morning.
This cold snap is a far cry from record breaking heat earlier this month when the thermometer climbed to 26 C in southern England and a mild March which was the fifth warmest ever for the U.K.
