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:
Grand Manan -2.8°C
Saint John -1.6°C
Kejimkujik NP -1.6°C

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.

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)
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.

Shubenacadie Sam sees his shadow, Shubenacadie, NS, 02 Feb 2020 (Twitter)
The first marmot in North America to make a weather prediction on Groundhog Day was Nova Scotia’s Shubenacadie Sam who saw his shadow early today which means another six weeks of winter.
However, Ontario’s Wiarton Willie and Pennsylvania’s Punxsutawney Phil didn’t see their respective shadows hence an early spring is expected.
So which groundhog do we believe?
The annual tradition originated in Germany and traces its roots to religion rather than science.
Environment Canada notes how data over the last 30 to 40 years shows that the groundhogs have only been correct about 37 percent of the time.
But admittedly, it’s a fun way to mark the midpoint of winter whether or not it wraps up early or drags on into spring.

Just days into the new year, a low pressure system has brought mostly snow to Atlantic Canada especially near the ocean.
For most of Nova Scotia, it was winter’s first major snowfall with up to 15 cm at Halifax Stanfield Airport and nearly 40 cm in Sydney.
The storm grazed Greater Moncton with only 3 cm of snow.
After leaving the Maritimes, the system brought 42 cm snow to St. John’s, Newfoundland and 30 cm to the Burin Peninsula with a peak wind gust of 106 km/h in Bonavista.
Meantime, forecasters say another low pressure system is coming midweek.
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.
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.
Light snow falls on Boxing Day, Truro, NS, 26 Dec 2019 (Dearing)
Despite a relatively snow-free December, Greater Moncton still managed to have a White Christmas this year after all – but just barely.
Environment Canada reports 2 cm of snow on the ground at the airport Christmas morning which fits its official definition.
Other parts of southern New Brunswick and Nova Scotia did not have snow including in Truro where I spent the holiday.
Meteorologists say odds of a White Christmas have decreased in recent years.
Here are the odds for select Canadian cities (1994-2017 versus 1955-2017):
Moncton – 65% / 73%
Fredericton – 50% / 76%
Saint John – 45% / 60%
Charlottetown – 55% / 78%
Halifax – 40% / 54%
Montreal – 70% / 76%
Toronto – 45% / 52%
Winnipeg – 100% / 98%
Calgary – 60% / 59%
