January all-time highs!

Before a cold front swept through the Maritimes, all-time record January highs were set across the region yesterday including 16.7 C at Greater Moncton International Airport.

New Brunswick’s all-time January high was set in Sussex at 17.3 C, narrowly beating the previous provincial record of 17.2 C in Moncton from 08 January 1930.

Nova Scotia’s all-time January record was set yesterday in Greenwood at 19.0 C followed closely by Cheticamp at 18.9 C while on Prince Edward Island, Summerside hit a new monthly high of 13.8 C and St. Peters reached a provincial high of 17.8 C.

Environment Canada says while the latest storm delivered almost 28 mm of rain in Moncton, more than a month’s worth fell in Mechanic Settlement at 128 mm and Bouctouche at 98 mm.

The peak wind gust was clocked in Saint John at 96 km/h.

Flooding then flash freeze

After a low pressure system brought heavy rain and strong winds gusting up to 74 km/h to Southeast New Brunswick early today, a cold front moved through the region plummeting temperatures below freezing.

The thermometer in Greater Moncton dropped an incredible 14 degrees in just one hour – from 15 C at 11am to 1 C at noon – and then fell below zero shortly afterward.

Today’s daytime high of 16.7 C has unofficially broken the 13 January record of 12.2 C from 1972.

Flooding was reported in various parts of Greater Moncton and the province was forced to close some roads due to high water levels.

Before the precipitation ends later tonight, rain will change to freezing rain mixed with ice pellets and then finally to snow.

Record January thaw

A few days ago it was extremely cold in Greater Moncton and today it felt like spring.

The unofficial high was 14.3 C which beats the record of 11.2 C from 2014 according to Environment Canada.

But emergency measures officials are warning New Brunswickers to be prepared for possible flooding this weekend with 50 to 100 mm of rain possible and a flash freeze warning.

The ground is mostly frozen and has a reduced ability to absorb heavy rainfall.

The temperature is forecast to fall below freezing by late Saturday which will lead to icy conditions.

Greater Moncton spared worst of storm

The ‘bomb cyclone’ or ‘snow hurricane’ – featuring a dramatic drop in atmospheric pressure when warm and cold air collided – has left the Maritimes and spared Southeast New Brunswick from the worst of its fury.

While strong winds were a factor throughout the region, Greater Moncton received less snow compared to further north and west.

To the south and east, more rain fell along with hurricane-force winds (up to 200 km/h gusts in western Cape Breton) which created powerful storm surges causing flooding along the coast.

Here are some totals from Environment Canada and local estimates:

  • Greater Moncton Airport  14 cm snow, 10 mm rain, 91 km/h wind gust
  • Bathurst  58 cm snow, 80 km/h wind gust
  • Fredericton  30 cm snow, 78 km/h wind gust
  • Saint John  5 cm snow, 20 mm rain, 87 km/h wind gust
  • Halifax Stanfield Airport  40 mm rain, trace snow, 122 km/h wind gust

The storm may have departed but Arctic air has filtered back into the Maritimes which will mean a bitterly cold weekend.

Major storm moves across Maritimes

An powerful Nor’easter has arrived in the Maritimes with strong, gusty winds bringing heavy rain for Nova Scotia and a snow/ice pellets/rain for New Brunswick and Prince Edward Island.

Winds were hurricane-force in the Halifax region at 117 km/h and thundersnow – a thunderstorm with snow – was recorded in Sydney.

Storm surge warnings are in place along the Atlantic coast as water levels will be high enough to cause some coastal flooding.

In Greater Moncton, snow began falling around noon with freezing rain/ice pellets by late afternoon and rain by evening.

Environment Canada says the storm will move out of the region by Friday afternoon but more frigid air is filtering in behind the system which will mean a very cold weekend.

‘Bomb cyclone’ barrels up U.S. East Coast

For the first time in 28 years, the capital of America’s Sunshine State had measurable snow.

Tallahassee may occasionally see snowflakes in winter but today was only the fourth time since 1950 that snow actually accumulated on the ground.

The wintry blast was thanks to a so-called bomb cyclone which originated off Florida’s east coast and is barreling up the Atlantic toward the Maritimes.

The intense storm system also brought heavy freezing rain to South Carolina and blizzard warnings have been posted from Virginia to Maine.

Environment Canada has issued a winter storm warning for Greater Moncton and Southeast New Brunswick with 30 cm of snow/ice pellets and 10 mm of rain as the temperature finally climbs above freezing.

The thermometer has not risen above zero since Christmas Day and seven straight days have been below -10 C.

Storm coming to N.B.

Several weather outlets are forecasting a major winter storm will hit the Maritimes bringing heavy snow and strong winds to New Brunswick just days into 2018.

Blizzard conditions are possible along with large waves and high water levels along the coast.

Nova Scotia may get more rain along the Atlantic coast while a rain/snow mix is likely inland.

Until the storm arrives, Arctic air remains firmly in place with several cities in Ontario setting new record lows on New Year’s Day including -22.6 C at Toronto Pearson Airport and -28.6 C at Ottawa Macdonald-Cartier Airport.

December 2017 – Cold and dry

Heavy snow falling in northeast Moncton, 09 Dec 2017 (Dearing)

December in Southeast New Brunswick started out on a normal note with above freezing daytime highs and chilly but not frigid overnight lows.

But an early Arctic blast settled in over the Maritimes by mid-month and Greater Moncton had five days below -10 C with four nights plunging to -20 C or lower.

After near normal precipitation last month, both rainfall and snowfall were below normal for December.

Two major snow events were recorded on 9-10 Dec (16 cm) and 25 Dec (20 cm) with a significant rainfall on 23 Dec (10 mm).

White Christmas across Canada

Technically in Truro, Nova Scotia, it wasn’t a White Christmas with snow falling later in the morning which changed to freezing rain, ice pellets and eventually rain.

But by late afternoon, winds gusted to almost 100 km/h which knocked down trees and power lines leaving thousands in the dark on Christmas Day.

In Greater Moncton, snow and blowing snow were factors on December 25 with about 20 cm accumulating – the heaviest snowfall so far this season.

Across Canada, Vancouver had a trace of white for Christmas while Victoria had 3 cm of snow.

Calgary is still digging out from a 30 cm snowfall a few days ago, Winnipeg had its coldest Christmas in 20 years plunging to -30 C and Toronto picked up 10 cm during the day.

Freezing rain creates icy conditions

Streets and highways in Greater Moncton turned into skating rinks early this evening after freezing rain began falling through Central and Southeast New Brunswick.

Social media users mentioned how numerous vehicles were sliding off the roads in icy conditions and Magnetic Hill had become an ice sheet.

A low pressure system from the Northeastern United States brought mixed precipitation which eventually changed to rain.

Meantime, Environment Canada is monitoring a major snowstorm expected Christmas Day which could bring 20 cm snow to parts of New Brunswick.
