Leaves are finally bursting out, Irishtown Nature Park, 24 May 2020 (Dearing)

Numerous record lows were set across the Maritimes early Sunday morning as temperatures plummeted under clear skies and light winds.

But the cold will be replaced by heat as the jet stream surges north over Eastern Canada this week.

Environment Canada has issued a special weather statement for New Brunswick with unseasonably warm weather expected for late May.

Records will be challenged in Greater Moncton as daytime highs soar to 30°C and humidex values reach the mid-30’s.

New record lows set on 24 May:

  • Woodstock -4.7°C
  • Edmundston -3.0°C
  • Grand Manan -2.8°C
  • Bouctouche -1.9°C

Active Atlantic hurricane season predicted

Hurricane

U.S. forecasters have unveiled their projections for the 2020 Atlantic hurricane season and it promises to be a busy one with 13 to 19 named storms and 6 to 10 becoming hurricanes.

The U.S. National Oceanic and Atmospheric Administration (NOAA) believes several factors are at play this year including above average sea surface temperatures, weaker tropical trade winds and an expected La Nina climate pattern.

Although the season doesn’t officially begin until 01 June, there has already been one named storm – Arthur – which had peak wind gusts of 95 km/h and neared the Southeastern U.S. before moving out to sea without striking land.

The Canadian Hurricane Centre will also be keeping an eye on storms which enter northern waters.

Last September, Hurricane Dorian made landfall near Halifax and caused destruction across Nova Scotia, Southeast New Brunswick and Prince Edward Island.

Late season snow!

Nova Scotia and Prince Edward Island saw more snow today which is becoming a bit unusual as April comes to an end.

A slow moving low pressure system brought several centimetres which mainly accumulated on colder surfaces such as grass and vehicles.

The Halifax area turned white and so did northern and eastern areas of the province and Cape Breton.

New Brunswick seemed to escape the snow except for a few scattered flurries.

UPDATE – New snowfall records:

Halifax Stanfield Airport – 28.2 cm (old record 19.3 cm from 1967)

Sydney Airport – 24.8 cm (old record 6.6 cm from 1971)

Warm spring day

Finally some warmth!

Southeast New Brunswick is trending slightly above normal for March but real heat has been absent until this weekend.

Greater Moncton reached 9.4°C which was a monthly high.

While Prince Edward Island and Cape Breton Island were cooler, some parts of the Maritimes got into the double digits.

Liverpool, Nova Scotia hit 13.9°C while Saint John recorded 10.5°C.

Ice cover shrinking in Gulf of St. Lawrence

While ice is shrinking in the Northumberland Strait, the central Gulf still has a fair amount of coverage especially north of Prince Edward Island and west of Cape Breton Island.

Warm front brings record highs

A slow moving warm front has brought precipitation and varying temperatures to the Maritimes.

About 15 cm of snow was expected in the north, while freezing rain and ice pellets fell in central areas and rain in the south.

Temperatures also ranged from well below freezing in northwestern New Brunswick to as high as 15°C in southwestern Nova Scotia.

Meantime, the thermometer has been rising in Greater Moncton over the past 24 hours with snow, ice pellets, freezing rain and now rain.

Wintry mix for New Year’s Eve

A wintry mix falls in NE Moncton, 31 Dec 2019 (Dearing)

The same storm system which impacted Ontario and Quebec is now creating travel havoc in the Maritimes with a mixed bag of precipitation.

Snow along with ice pellets began in Southwest New Brunswick on New Year’s Eve morning and gradually spread to Greater Moncton by early afternoon.

About 14 cm of snow and ice pellets could accumulate in the Southeast before a changeover to rain around midnight as temperatures rise above freezing.

Snowfall warnings have been posted in western and northern New Brunswick with 15 to 30 cm likely with lesser amounts for Prince Edward Island and mostly rain is forecast for mainland Nova Scotia.

UPDATE

Moncton received 5.4 cm of snow, Saint John had 3.4 cm while about 10 cm fell in Fredericton but near 30 cm in Woodstock.

Heavy, wet snow creates chaos

An early blast of winter in Moncton, 09 Nov 2019 (Dearing)

Some drivers were prepared when snow entered the forecast for the first time this week and had their winter tires installed.

But many drivers were caught off guard by the heavy, wet – sloppy – snow which fell across Southern New Brunswick, Prince Edward Island, northern Nova Scotia and southwestern Newfoundland.

A low pressure system brought rain on Thursday but snow fell by evening as the temperature dropped to the freezing point.

The snow continued throughout Friday creating slippery roads which left plow operators scrambling to deal with the early blast of winter.

Many minor accidents were reported with vehicles sliding into the ditch.

The Trans Canada Highway at Cobequid Pass was forced to close for several hours Friday night after numerous tractor trailers got stuck in snow and blocked the road.

Snowfall amounts (Thu-Fri) in cm:

  • Corner Brook 19.4
  • Greater Moncton 18.8
  • Fredericton 10-15 (estimate)
  • Deer Lake 13
  • Saint John 8.9
  • Halifax Stanfield 5.8
  • Charlottetown 3.9
