A slow moving warm front has brought precipitation and varying temperatures to the Maritimes.

Temperatures also ranged from well below freezing in northwestern New Brunswick to as high as 15°C in southwestern Nova Scotia.

Meantime, the thermometer has been rising in Greater Moncton over the past 24 hours with snow, ice pellets, freezing rain and now rain.

Some of the coldest lows yet this winter were recorded in February yet the mean monthly temperature in Greater Moncton was actually above normal based on the 30-year average.

Four overnight lows dropped to -20°C or lower with a frigid -24.4°C on 15 Feb which was the coldest minimum in five years (since February 2015).

Eleven days were below freezing but daytime highs climbed above freezing during the final week of the month.

Three major storms brought above normal snowfall but a scant 1.0 mm of rain was recorded which was well below the average of 28 mm.

Spring 2020 forecast unveiled

Spring 2020
The Weather Network has unveiled its spring forecast for the months of March, April and May.

Recent spring-like weather in New Brunswick has made many wonder when the real season will arrive.

TWN meteorologist Doug Gilham expects we should still expect some wintry weather during March which is not unusual but he thinks temperatures should be near normal for the three month period.

Gilham believes it will be a wet season overall with above normal precipitation especially rainfall.

Last year, spring was very late and cold weather just wouldn’t let go.

Snow was recorded as late as 21 May in Greater Moncton.

Winter storm sweeps Eastern Canada

Hours of ice pellets!

Jan 12 storm

Back-to-back low pressure systems brought a messy mix of precipitation to much of the Maritimes over the weekend.

Rain began falling Saturday with a near record warm high of 11 C in Greater Moncton which melted any snow on the ground.

However, the next system brought colder temperatures and more than ten hours of ice pellets (sleet) in Southeast New Brunswick sometimes mixed with snow and freezing rain.

About 15 cm of ice pellets and snow accumulated Sunday which forecasters say is quite rare and it was certainly heavy to move.

December 2019 – Mild with little snow

It felt like winter was on pause during December in Southeast New Brunswick.

After significant snow on 07-08 November, many thought winter arrived early again.

But more rain fell and the heaviest snow was a mere 9 cm – paltry by Greater Moncton standards.

Although the temperature remained below freezing on 13 days and most daytime highs were just slightly above zero, the thermometer did climb above 10°C on four occasions.

Wintry mix for New Year’s Eve

A wintry mix falls in NE Moncton, 31 Dec 2019 (Dearing)

The same storm system which impacted Ontario and Quebec is now creating travel havoc in the Maritimes with a mixed bag of precipitation.

Snow along with ice pellets began in Southwest New Brunswick on New Year’s Eve morning and gradually spread to Greater Moncton by early afternoon.

About 14 cm of snow and ice pellets could accumulate in the Southeast before a changeover to rain around midnight as temperatures rise above freezing.

Snowfall warnings have been posted in western and northern New Brunswick with 15 to 30 cm likely with lesser amounts for Prince Edward Island and mostly rain is forecast for mainland Nova Scotia.

UPDATE

Moncton received 5.4 cm of snow, Saint John had 3.4 cm while about 10 cm fell in Fredericton but near 30 cm in Woodstock.

Mild but stormy conditions

Another intense low pressure system moved through the Maritimes on the weekend bringing a new round of heavy rain and strong winds.

After a bone-chilling start, winds changed direction and a southerly flow pushed the high in Greater Moncton to 13.8°C – close to the record of 13.9°C from 2008.

Winds were strong with gusts up to 87 km/h in Southeast New Brunswick and a peak of 91 km/h reported in Bathurst.

As the storm headed to Newfoundland, cold air plunged into the region and temperatures fell below freezing and may stay that way for several days.

Wind & rain cause damage

Strong winds and heavy rain from a strong low pressure system caused damage to properties and localized flooding in New Brunswick and Nova Scotia.

The Saint John area was hard hit with wind gusts up to 95 km/h which led to power outages and roof damage to at least two apartment buildings.

No one was hurt but all tenants were evacuated and assisted by the Red Cross.

Many roads were closed due to flooding or fallen trees and there were voluntary evacuations in Sussex in low lying areas.

The storm also brought mild, record-breaking temperatures with highs of 11°C in Edmundston and 12°C in Bathurst and Woodstock.

Greater Moncton hit 13.7°C but the record for 10 December was 15°C from 1957.

Rainfall totals (in mm) as of 8am on 10 December 2019:

  • Mechanic Settlement, NB  94 mm
  • Saint John Airport  63 mm
  • Kejimkujik NP, NS  53 mm

Heavy rain may cause flooding

Snow settles in Moncton, 05 Dec 2019 (Dearing)

The latest low pressure to invade the Maritimes is bringing heavy rain and strong winds to Southern New Brunswick and Northern Nova Scotia.

Environment Canada has issued a rainfall warning with up to 70 mm possible especially along the Fundy coast and strong winds gusting up to 90 km/h.

Meteorologists say that much rain is a lot for frozen ground to absorb and along with an existing snowpack could create localized flooding.

After a few days with below freezing temperatures, the small amount of snow in Greater Moncton has been taken away by the rain and a mild high of 12°C.

The forecast is calling for much colder air behind this system with some snow likely on Wednesday.
