Icy slush in NE Moncton, 03 Dec 2019 (Dearing)
After exiting Ontario, a Colorado Low moved into the Maritimes bringing freezing rain and rain to Nova Scotia along with mixed precipitation to Southeast New Brunswick.
The system shut down schools in many parts of the region on Tuesday with icy roads being a major factor.
Greater Moncton had several hours of freezing rain and ice pellets mixing with snow (3 cm) and later rain (15 mm) as the temperature climbed slightly above freezing.
Northern and western New Brunswick received mostly snow with 10 cm in Fredericton, 18 cm in Miramichi and 27 cm in Woodstock.
This has been a very snowy winter across northern New Brunswick with Edmundston and Bas-Caraquet recording 114 cm of snow on the ground as of today (06 March).
Some unofficial reports have indicated a snow depth of more than 160 cm in some mountainous areas.
Southern New Brunswick also has plenty of snow but often it has been mixed with rain, freezing rain or ice pellets which have lowered accumulations.
Greater Moncton now sits at 53 cm (the most so far this season) and snowbanks are getting high enough to cause visibility issues at some intersections.

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

A frosty Saturday morning proved record breaking at the Greater Moncton International Airport when the thermometer plunged to -6.6°C which breaks the previous cold low from 1998 by 0.1°C.
Frigid temperatures were also set in Edmundston at -12.2°C, Woodstock at -11.7°C and Saint John at -8.4°C with weather records going back to 1886.

Snow settles on grass, vehicles and rooftops in NE Moncton, 25 Oct 2018 (Dearing)
Even by New Brunswick standards, snow in October is not very common.
But a low pressure system dropped more than 15 cm of heavy, wet snow over western and northern parts of the province creating commuter chaos in Fredericton yesterday.
After getting drenched with 38 mm of rain, Greater Moncton received a light coating of snow this morning which stuck to rooftops, vehicles and grassy areas but it melted by midday.

- Charlo/Belledune area. 23 cm

It may have been the warmest summer in the Maritimes in almost a century but some parts of the region woke up to below freezing temperatures and frost this morning!
That means some areas had a growing season which barely lasted 100 days since the last spring frost for many was 04 June.
Greater Moncton was definitely chilly with an early morning low of 3.0°C which was close to the record low of 1.1°C from 1956.

A slow moving frontal system brought heavy rain to western New Brunswick with about 20 mm falling per hour in the southwest.
Environment Canada reported 174 mm of rain in St. Stephen over a two day period which is a shocking amount considering about 180 mm fell from June to September.
Other amounts include 112 mm in Edmundston, 93 mm in Woodstock and 74 mm in Fredericton.
Rainfall totals were much lower in Southeast New Brunswick where only 27 mm fell at the Greater Moncton International Airport.
Tropical air with this system broke more record highs in Atlantic Canada with a maximum of 23.4 C in Moncton and Bouctouche, 23.5 C in Cheticamp, 22.0 C in Deer Lake and 21.2 C in Happy Valley-Goose Bay.

Having a heat wave in late September is unusual for Southeast New Brunswick but even more so is that the highest temperature of 2017 has occurred in early autumn.
The thermometer soared to 31.1 C yesterday (26 September) at the Greater Moncton International Airport which breaks the previous maximum of 29.6 C from 2007 and records date back to 1881.
