Return to winter

A strong low pressure system is expected to bring a lot of snow, some rain and wind to Southeast New Brunswick starting Thursday night.

About 15 cm could fall in Greater Moncton prompting Environment Canada to issue a snowfall warning.

Strong winds will coincide with high tide along the Northumberland Strait creating storm surge.

This could be the heaviest snowfall event since 01 March when 14 cm fell.

March 2020 – Warm and dry

About 15 cm of snow was expected in the north, while freezing rain and ice pellets fell in central areas and rain in the south.

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.

January 2020 – Warmer than normal

Glancing at the data for January 2020, one would think it was as cold if not colder than normal in Southeast New Brunswick.

The thermometer sank below -10°C on sixteen days while four of those days dropped to -20°C or lower during the month.

Despite the frigid weather, January was in fact almost three degrees above normal in Greater Moncton.

Despite two major snowfalls (including one event near 30 cm) and some rainfall, precipitation was close to the thirty-year average.

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.
