Temperature contrast 8pm, 12 Nov 2019 (earth nullschool.net)
Snow began falling in Southeast New Brunswick Monday night and later changed to freezing rain and then rain by Tuesday afternoon.
The temperature climbed to a balmy 14°C in Greater Moncton and 18°C in Greenwood, Nova Scotia.
But as the low pressure system moved out of the Maritimes toward Newfoundland, winds shifted to the northwest causing the thermometer to drop rapidly Tuesday night with a return to snow when it fell to freezing again.
Overnight low records could be challenged in the region by early Thursday as cold Arctic air takes hold.
Post-tropical depression Erin interacted with an incoming low pressure system to produce lots of rain in the Maritimes.
Environment Canada says the heaviest amounts were recorded in northern Nova Scotia and the Annapolis Valley – Parrsboro and Greenwood each had more rain from this storm than all of July and August combined.
Some roads were damaged and even washed out by surface runoff or flooding.
Erin’s direct path along Nova Scotia’s south shore produced wind gusts up to 80 km/h.
The storm brought tropical air with a high of 23°C in Greater Moncton on Friday but a humidex of 32.
Rainfall totals (mm):
- Parrsboro 162
- Greenwood 127
- Kentville 115
- Summerside 67
- Fredericton 56
- Moncton 50
- Halifax (city) 48

Lots of rain, freezing rain and ice pellets have been recorded so far this year in Southeast New Brunswick but snow has been somewhat scarce – until today.
A Colorado Low made its way across the continent this week bringing lots of snow to the American Midwest, Southern Ontario and Southern Quebec before arriving in the Maritimes.
Greater Moncton received 26 cm of snow followed by ice pellets and some freezing rain/drizzle along with strong winds which created poor visibility.
Snowfall amounts were fairly consistent across most of Nova Scotia with 22 cm at Greenwood and Halifax Stanfield Airport, 21 cm in Sydney but only 11 cm in Yarmouth.
Environment Canada says cold weather will replace the snow for late week with a brief warmup and rain expected this weekend.

The second of three winter storms in less than a week has delivered another dumping of snow but this time it was more evenly distributed throughout the Maritimes.
The snow was heavy and wet especially in Southeast New Brunswick.

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

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.

Nine communities across New Brunswick set new record highs yesterday and the same will likely happen again today.
Greater Moncton was the warmest spot in the province climbing to 23.1 C which broke the old maximum temperature of 22.8 C from 1928.
Greenwood was among six communities in Nova Scotia breaking records with a high of 24.5 C.
Four records fell on Prince Edward Island including Charlottetown at 21.7 C.
Environment Canada says the Maritimes is enjoying a late October heat wave because the region is sandwiched between low pressure and high pressure allowing warm, southerly air to move northward.
