November 2019 – Colder and snowier

November got off to a mild start in Greater Moncton – the monthly high 19.4 C was actually 0.1 degrees warmer than October’s maximum – but temperatures quickly tumbled especially overnight.

Only two nights were actually above freezing with the coldest weather around the middle of the month.

The first measurable snow was recorded on 07-8 (18.8 cm) which was more than half of the November total and rainfall was lighter than usual.

Daytime highs struggled to climb above freezing especially during the last two weeks which led to a below normal monthly average.

First -10°C low in the fall

First -10
Although it seems like really cold weather arrived earlier than usual, the chart above shows a drop of -10°C occurred on the same date last year in Greater Moncton – 14 November.

Over the last seven years, the temperature has gotten that cold between mid-November and early December.

The thermometer will likely sink to -15°C sometime later next month.

The last time it dropped that low in Southeast New Brunswick was 10 March.

First Below 0°C Daytime High

First Below 0
Cold, wintry weather seems to have arrived earlier this season in New Brunswick and Greater Moncton is no exception.

As shown above, the first below freezing daytime high was recorded on 09 November which makes it the earliest date in recent years.

In addition, the thermometer has already dropped to -10°C this month which I will outline in an upcoming post.

Early blast of Arctic air

The jet stream took a big dip south this week allowing Arctic air to envelop the eastern United States and eastern Canada.

Temperatures dropped to freezing all the way to the Gulf of Mexico.

Meteorologists say the early icy blast was more typical of January than mid-November.

New record lows were set in Ontario where CFB Borden fell to -24°C and Toronto Pearson Airport dropped to -14°C.

The coldest low of the season was set in Greater Moncton today at -10°C and just a couple degrees shy of the record.

The Southeast New Brunswick forecast calls for a roller coaster ride this weekend followed by more seasonable temperatures next week.

Early snow for southern Ontario & Quebec

An early winter storm tracked south of the Great Lakes on Monday and brought snow to Southern Ontario and Southern Quebec.

Snowfall amounts generally ranged between 10 and 30 cm.

Environment Canada says Toronto marked its earliest major snowfall on record with about 15 cm.

Arctic air has filtered in behind the storm prompting the city to issue an extreme cold weather alert with a possible overnight low of -15°C.

Snowfall amounts (cm), Tuesday 5pm EST:

  • Montreal 20
  • Quebec City 20
  • Windsor 19
  • Hamilton 17
  • Toronto (downtown) 15
  • Ottawa 13

Windy start to November

Blustery but mild weather on Halloween continued throughout the first day of November in Southeast New Brunswick.

A cold front created strong winds with a sustained high of 64 km/h and a peak gust of 94 km/h at the Greater Moncton Airport.

Many trees and branches – already weakened by Dorian earlier this fall – came down onto power lines with NB Power dealing with almost 60,000 customers without electricity by late Friday.

Environment Canada warned of gusts up to 110 km/h in the Tantramar Marsh which forced the shutdown of the Trans Canada Highway between Amherst and Sackville until winds subsided.

The daytime high on 01 November was 19.4°C which was slightly warmer than the October maximum of 19.3°C.

The same storm system also hit Quebec where more than one million customers lost power, one man was killed by a falling tree and a canopy collapsed at a service station.

Hurricane season begins

2018 hurricanes

Today marks the beginning of the 2019 hurricane season which will run until the end of November.

For a record fifth consecutive year, storm activity began before the 01 June official start date when Subtropical Storm Andrea formed on 20 May.

The U.S. National Oceanic and Atmospheric Administration (NOAA) is forecasting a near normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes.

The Canadian Hurricane Centre begins issuing statements when a storm is within three days of entering a response zone covering Eastern Canada and adjacent waters.

Winter won’t let go!

Snow in west end Moncton, 09 April 2019 (Dearing)

Real winter weather in New Brunswick started early – back in mid-November – and the relentless season hangs on.

Greater Moncton recorded 7 cm of snow overnight with more than 10 cm in southwestern New Brunswick and western Nova Scotia.

The strong April sun had melted most it by the end of the day.

But another weak system tonight could bring another 4 cm.

Warmer weather is on the way with Environment Canada forecasting highs in the double digits by the weekend.

Warmest since early November!

The last day of March proved to be the warmest day in Greater Moncton since 03 November when the thermometer hit 17.1 C.

The daytime high reached a balmy 16.8 C and the New Brunswick hot spot was 19 C in Sussex which brought residents outdoors to walk, run, hike and play.

The maximum was actually close to the record for the date which was 17.5 C from 2006.

But a passing cold front will drop the temperature considerably overnight as rain changes to snow and Monday’s high struggles to reach slightly above freezing.

Is spring around the corner?

The Weather Network has unveiled its spring 2019 forecast covering March, April and May – so what can New Brunswick expect?

It’s been a long, cold and stormy winter which began in mid-November but TWN believes after another cold wave in early March, a warmer pattern will develop later in the month.

Meteorologist Michael Carter says more consistent spring-like weather is possible by early April.

Both temperatures and precipitation are expected to be near normal for the season.

Carter adds flooding is a possibility given normal spring run-off combined with any rain or snow that falls.

But he thinks it won’t be as stormy this spring compared to past years.
