A line of strong thunderstorms moved across New Brunswick, western Prince Edward Island and eastern Nova Scotia on Saturday bringing heavy downpours, hail and strong winds.

Greater Moncton was under a severe thunderstorm warning for a few hours with hail about 1 cm in diameter being reported outside the city.

Heavy rain also caused flash flooding in downtown Shediac with social media posts showing vehicles making their way through water clogged streets.

Temperatures also plunged from the low 20s to the mid-teens as the storms passed.

Although the rain is needed, concert goers might disagree with the first show being staged on Magnetic Hill today in four years.

Heat building in the Maritimes

A heat warning has been in place since the start of the weekend in much of New Brunswick, Nova Scotia (except for Cape Breton) and Prince Edward Island.

In Greater Moncton, the temperature climbed to 30 C on Saturday and 29 C today but the forecast calls for 30 C on Monday and 31 C for Tuesday and Wednesday.

Overnight lows are not expected to drop that much either hovering around 18 to 19 C.

While humidity has been relatively low this weekend at around 50 percent or less, Environment Canada says the warm air mass will become more humid this week.

The only relief will be along the Fundy coast where temperatures will stay in the low 20s.

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.

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.

Snowstorm departs, rainstorm coming

More than 24 hours after it started, snow finally stopped falling in Southeast New Brunswick and a slow moving low pressure system headed to western Newfoundland.

Greater Moncton picked up between 20 and 25 cm and schools in the region were closed for two days.

Higher amounts of snow fell in western New Brunswick, western Prince Edward Island and the Cape Breton Highlands.

Environment Canada says the next major weather should arrive Friday with warm, moist air boosting temperatures and bringing significant rainfall.

Back-to-back systems batter N.B.

Southeast New Brunswick has been under a gloomy, grey sky all week thanks to a couple of low pressure systems.

The first one brought rain, drizzle and fog while the second brought heavy, wet snow to make this November one of the snowiest in recent memory.

Eastern New Brunswick got the brunt of the snow with Miramichi picking up a whopping 43 cm of snow while Greater Moncton had a hefty 28 cm.

Most of the snow in Nova Scotia fell over northern and eastern areas with heavy rain falling elsewhere.

Strong winds up to 89 km/h caused a storm surge along the Gulf of St. Lawrence coast.

Gusts of more than 100 km/h were reported on Prince Edward Island and Cape Breton Island.

Bitter cold ahead of more snow

Temperatures sunk early Monday across the Maritimes with some New Brunswick locations shattering records by almost five degrees dating back to the 1880’s.

The bitter cold precedes another storm system which could bring up to 25 cm of snow to southern New Brunswick, most of Prince Edward Island and northern Nova Scotia.

While it plunged to -14.7°C in Greater Moncton, the 1936 record still stands at -16.7°C.

Here are some of the new record lows set in the region on 19 November:

  • Bathurst, NB -22.5°C
  • Woodstock, NB -21.4°C
  • Miramichi, NB -20.2°C
  • Kouchibouguac, NB -20.0°C
  • Summerside, PE -15.7°C
