Deep snow cover across N.B.

NB map
This has been a very snowy winter across northern New Brunswick with Edmundston and Bas-Caraquet recording 114 cm of snow on the ground as of today (06 March).

Some unofficial reports have indicated a snow depth of more than 160 cm in some mountainous areas.

Southern New Brunswick also has plenty of snow but often it has been mixed with rain, freezing rain or ice pellets which have lowered accumulations.

Greater Moncton now sits at 53 cm (the most so far this season) and snowbanks are getting high enough to cause visibility issues at some intersections.

December 2018 – Cold & dry

December turned out to be another cold month in Greater Moncton continuing a trend which began in October.

An early Arctic air mass kept daytime highs below freezing for a lengthy ten day stretch.

The month did prove to be less stormier than November with below normal rainfall and snowfall.

While Southeast New Brunswick had a snow cover for a few weeks prior to Christmas, it had mostly disappeared by 25 December.

White Christmas

While much of Canada is covered in white on this Christmas Day, many of the major cities are without a snow cover.

Only the Prairie cities of Winnipeg, Saskatoon and Edmonton were guaranteed a White Christmas.

Recent heavy rain and warm temperatures have erased the snow pack across Nova Scotia, Prince Edward Island and southern New Brunswick.

Traditionally Greater Moncton has a 65 percent chance of having a White Christmas.

Today, the airport recorded 3 cm of snow lying on the ground but much of the city and surrounding area have no snow cover at all.

April 2018 – Spring sputters

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.

Snow disappears!

The snow has finally vanished from the front lawn of my home in northeast Moncton!

The top photo shows a lot of snow on 09 April while the last of it melted by 19 April in the bottom photo.

Despite below normal temperatures which struggled to reach 10 C, the snow disappeared in just 10 days.

Snow cover lingers across Canada

snowApr18
We know it snows in Canada in April but an astonishing amount of snow remains on the ground for the middle of the month.

The only snow-free areas as of 18 April are mainland Nova Scotia, extreme SW Ontario, southern Manitoba, SW Saskatchewan, SE Alberta, coastal British Columbia and southern valleys of the interior.

Even much of the northeastern United States and the upper Great Lakes region is still covered in white.

In Greater Moncton, the snow has mostly disappeared except for man-made snowbanks but as much as 100 cm remains in northern New Brunswick.

March 2018 – Stormy!

Although March came in like a lamb, it behaved like a lion in the days to follow with four Nor’easters over two weeks in Southeast New Brunswick.

The first storm brought 15 cm, the second and third storms each delivered 16 cm and the fourth packed the biggest punch with 30 cm.

By 23 March, the snow cover in Greater Moncton had reached 40 cm which was the heaviest of the winter even though it was already spring.

Temperatures during the first half were mild averaging near the freezing point with brief cold snaps around the middle and near the end of the month.

Freezing fog!

Residents of Southeast New Brunswick and Prince Edward Island woke up to freezing fog this morning.

This occurs when water droplets develop during fog and freeze instantly when temperatures are below freezing.

The last three early mornings in Greater Moncton have been below -10°C and have dropped to a near record low of -15.4°C.

With nearly 40 cm of snow on the ground, this is the heaviest cover of white this winter season – keeping in mind this is now early spring.

Snow vanishes!

The snow cover in Greater Moncton has disappeared after the latest storm system rolled through with mixed precipitation and mild temperatures.

Rainfall amounts varied from 20 to 70 mm across New Brunswick, up to 8 hours of freezing rain fell in Gagetown and 20 cm of snow was recorded in Bathurst and Edmundston.

Record highs for 23 January were set in Saint John at 10.4 C and St. Stephen reached 11.3 C.

Since a consistent snow cover began on 09 December in Southeast New Brunswick, the ground has been bare a couple of times for short periods.

April 2017 – Spring sputters

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.
