The Petitcodiac River in Moncton looking toward Dieppe, 28 January 2018 (Dearing)
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.

Flooding along the River Seine in Paris, France, 27 Jan 2018 (Reuters)
According to France’s meteorological agency, rain in December and January has led to the third wettest period ever in Paris which is why the River Seine and other tributaries in northern France have spilled their banks.
The river is expected to peak on Sunday at 6 metres – normally it measures 2 metres – slightly below the exceptional flooding in 2016 and the disastrous flood of 1910.
Some riverside restaurants have been submerged and roads and parks have been closed due to high water levels.
All boat traffic on the Seine has been halted including tourist cruises, some Metro stations are shuttered and the Louvre has shut down the museum’s lower level as a precaution.
Bare ground in west end Moncton after rain washes away snow cover, 24 Jan 2018 (Dearing)
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.

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.
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.

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.
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).
