Environment Canada issued a flash freeze warning for much of New Brunswick, Nova Scotia and Prince Edward Island early today.
A low pressure system brought snow, later rain and then snow again after the temperature plummeted as Arctic air pushed back into the region.
The daytime high in Greater Moncton was 3.0 C at 11am and pooling water began freezing when the thermometer dropped below freezing by 3pm.
By early Saturday, forecasters say the low could drop to -19 C but temperatures will moderate on Sunday before falling again on Monday.

The first month of 2018 proved to be quite a roller coaster ride in Southeast New Brunswick.
Bitter cold to begin January was briefly erased by a fast-moving ‘bomb cyclone’ until another Arctic blast sunk the low to -22.3 C with a bitter wind chill of -36.
A record thaw saw the thermometer climb to 16.7 C in Greater Moncton – the highest ever in January – and a new all-time provincial high of 17.3 C in Sussex.
Precipitation was above average overall with near normal snowfall – 25 cm was the heaviest snow event on 30-31 – and about twice as much rainfall.

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
A classic Nor’easter arrived in the Maritimes today bringing an abrupt end to a snow free Southeast New Brunswick.
Environment Canada says the intensity of the storm led to a snowfall warning and a blowing snow advisory being issued by mid-afternoon for Greater Moncton.
By 6pm, about 16 cm of snow had fallen with winds gusting up to 74 km/h creating poor visibility in blowing snow.
In Nova Scotia, about 16 cm fell in both the city of Halifax and at Stanfield Airport with an impressive 40 cm recorded in Sydney.

With a daytime high of 7 C, it felt more like spring than midwinter along the Riverfront Trail in Moncton today.
Skateboarders instead of snowshoers were found along with joggers in shorts and T-shirts and a group having a picnic in the late afternoon sun.
A lack of snow cancelled numerous winter activities this weekend and ski resorts put snowmaking machines into overdrive to open just a handful of runs.
Environment Canada says winter is returning with a low pressure system arriving Tuesday with up to 15 cm of snow possible in Southeast New Brunswick.

The snow cover in Greater Moncton has disappeared after the latest storm system rolled through with mixed precipitation and mild temperatures.
Rainfall amounts varied from 20 to 70 mm across New Brunswick, up to 8 hours of freezing rain fell in Gagetown and 20 cm of snow was recorded in Bathurst and Edmundston.
Record highs for 23 January were set in Saint John at 10.4 C and St. Stephen reached 11.3 C.
Since a consistent snow cover began on 09 December in Southeast New Brunswick, the ground has been bare a couple of times for short periods.

A low pressure system from the west is bringing another mixed bag of precipitation to the Maritimes and once it departs more cold air will filter in behind it.
Schools were cancelled in New Brunswick today as snow began in the morning followed by a changeover to ice pellets and freezing rain and eventually to rain as the temperature climbed above freezing.
Flooding is possible again since the partially frozen ground is less able to absorb heavy rainfall.
Environment Canada issued a freezing rain warning for Greater Moncton but it was dropped later in the day with less than an hour of ice pellets/freezing rain recorded.
The temperature is expected to reach 10 C by early Wednesday before plunging to -13 C by early Thursday – a difference of 23 degrees in less than a day.
Freshly fallen snow in west end Moncton, 18 Jan 2018 (Dearing)
Almost 20 cm of snow fell in Greater Moncton yesterday and it came without any official weather warnings.
Some media outlets were suggesting more than 20 cm while Environment Canada was calling for between 10 and 14 cm.
The snowfall turned out to be the second heaviest of the season so far after the Christmas Day storm.
The low pressure system also brought 14 cm to Saint John, 17 cm in the Fredericton area and about 20 cm in Grand Manan and Alma.
Even higher amounts were recorded in eastern Prince Edward Island, northern Nova Scotia and Cape Breton Island.

Heavy rain and fast melting snow from the weekend storm swelled rivers and streams throughout Southern New Brunswick.
Floodwaters swept away culverts and damaged bridges including the historic covered Bell Bridge which crews say is beyond repair and will be torn down.
Washouts and severe erosion forced the Department of Transportation to close dozens of roads and reduce others to one lane.
Residents have been urged to report storm damage to the provincial Emergency Measures Organization and contact their insurance companies for losses.

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.
