Frost free season approaches

May is here which means it won’t be long before Jack Frost visits Atlantic Canada for the last time this spring.

Mid to late May is typically when the last frost arrives in Greater Moncton, early in the month for Halifax and late April for Yarmouth.

Early to mid June dates are normal for most of Newfoundland and Labrador.

Last year in New Brunswick and Nova Scotia, frost appeared as late as early June which proved disastrous for grape, blueberry and strawberry farmers.

A low pressure system approached the Maritimes from the northeastern United States late Sunday night.

Snow began in New Brunswick early Monday and intensified throughout the day before tapering off to freezing drizzle by evening.

About 24 cm fell in Greater Moncton which was the second heaviest snowfall of the season after the storm on 13 February.

The system also brought snow to western and central Newfoundland later on Monday with freezing rain to the Avalon Peninsula.

Snowfall amounts (cm) as of 1AM Tuesday from Environment Canada:

  • Sydney: 26
  • Saint John Airport: 26
  • Greater Moncton Airport: 24
  • Deer Lake: 23
  • Fredericton: 21
  • Miramichi: 21
  • Charlottetown: 19
  • Greenwood: 19
  • Halifax Stanfield Airport: 17
  • Bathurst: 14
  • Gander: 14

Heaviest snowfall of 2019

Lots of rain, freezing rain and ice pellets have been recorded so far this year in Southeast New Brunswick but snow has been somewhat scarce – until today.

A Colorado Low made its way across the continent this week bringing lots of snow to the American Midwest, Southern Ontario and Southern Quebec before arriving in the Maritimes.

Greater Moncton received 26 cm of snow followed by ice pellets and some freezing rain/drizzle along with strong winds which created poor visibility.

Snowfall amounts were fairly consistent across most of Nova Scotia with 22 cm at Greenwood and Halifax Stanfield Airport, 21 cm in Sydney but only 11 cm in Yarmouth.

Environment Canada says cold weather will replace the snow for late week with a brief warmup and rain expected this weekend.

Snowfall totals so far this winter

It should come as no surprise that Greater Moncton is on top of the snowfall totals list in the southern Maritimes although locations in northern New Brunswick have received even heavier amounts.

Michael partly to blame for rain

Starting late Wednesday and lasting into Friday, a warm front and low pressure system eventually combined with moisture streaming northward from Tropical Storm Michael.

As these two systems began to interact, a significant amount of rain fell over parts of the Maritimes.

Rainfall summary in millimetres as of Saturday 5am ADT:

  • Doaktown: 47.2
  • Greater Moncton Airport: 39.4
  • Fredericton: 36.2
  • Saint John: 35.6
  • Grand Manan: 34.5
  • Halifax Stanfield Airport: 55.4
  • Yarmouth: 70.4
  • Kejimkujik: 47.7

A good soaking!

An intense low pressure system from the Great Lakes moved across New Brunswick Wednesday night and brought heavy rain especially along the Fundy Coast.

Alma at the entrance of Fundy National Park recorded 121 mm which is more than a month’s worth of rain in just 24 hours.

While it was a deluge for some, it was definitely much needed precipitation.

Here are more rainfall amounts:

  • Harvey, NB. 80 mm
  • Yarmouth, NS. 75 mm
  • Saint John, NB. 55 m
  • Halifax Airport, NS. 28 mm
  • Greater Moncton. 24 mm

Nor’easter number four!

Moncton’s west end after the latest Nor’easter, 23 March 2018 (Dearing)

It seems a bit strange the largest single snowfall this winter in Greater Moncton actually occurred on the second full day of spring.

Environment Canada says Southeast New Brunswick hit the snow jackpot from the fourth Nor’easter this month with more than 30 cm recorded.

A storm on 30 January was the previous snowfall event winner with almost 25 cm.

Strong winds were also a factor in this storm gusting at times to 82 km/h.

Here are some other snowfall totals:

  • Kentville, NS  24 cm
  • Alma, NB  20 cm
  • Yarmouth, NS  18 cm
  • Sussex, NB  17 cm
  • Charlottetown, PEI  12 cm
  • Halifax Stanfield Airport, NS  11 cm
  • Bathurst, NB  8 cm
  • Saint John, NB  6 cm

Nor’easter packs bigger punch than expected

Noreaster30Jan18
The track of the latest Nor’easter hugged the Atlantic coast of Nova Scotia which ultimately led to more snow in Southeast New Brunswick than forecasters first thought.

Environment Canada originally predicted 10 cm but more than double fell in Greater Moncton which ended up with the highest snow total in the Maritimes.

This was a classic Nor’easter with strong winds reaching a peak gust of 78 km/h creating blowing and drifting snow in open areas.

Here are some regional totals as of 8am ADT on 31 January:

  • Greater Moncton Airport:  25 cm
  • Halifax International Airport: 23 cm
  • Greenwood: 20
  • Sydney:  20
  • Halifax (downtown): 19
  • Charlottetown:  19
  • Bathurst:  18
  • CFB Gagetown:  14
  • Yarmouth:  13
  • Saint John Airport:  11

Nor’easter nails Maritimes

The latest Nor’easter moved up the U.S. Eastern Seaboard with lots of energy as it headed for the Maritimes.

The winter storm brought heavy snow and strong northeast winds to the region.

Snowfall totals as of midday:

St. Stephen: 38 cm

Greater Moncton: 24 cm

Charlottetown: 24 cm

Fredericton: 23 cm

Saint John: 19 cm

Kentville: 19 cm

Heavy snow hammers Maritimes

An intense low pressure system is now over Newfoundland after dumping up to 40 cm of snow on parts of the Maritimes overnight.

Snowfall was heaviest over central Nova Scotia, the Annapolis Valley and Prince Edward Island.

For Greater Moncton, this storm delivered the most snow since 30 November when more than 25 cm was recorded.

Fortunately this is light, dry snow since it fell when temperatures were cold (about -10 C or so) and it is much easier to move than wet, moisture-laden snow.

As expected, northern New Brunswick got off easy this time with only 3 cm reported in Bathurst.

Snow totals as of 8am AST:

Greater Moncton Airport 22 cm

Gagetown 23 cm

Saint John Airport 21 cm

Halifax Stanfield Airport 33 cm

Halifax downtown 26 cm

Yarmouth 26 cm

Greenwood 36 cm

Sydney 27 cm

Charlottetown 35 cm
