Messy mix falls over Maritimes

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.

A major winter storm made its way across the United States during the American Thanksgiving weekend disrupting travel plans for millions.

The massive system began on the West Coast as a bomb cyclone bringing wind gusts up to 160 km/h and heavy amounts of snow in the mountains.

Strong winds accompanied by a mixture of rain, freezing rain, ice pellets and snow fell from the Great Plains to the Midwest and into the Northeastern U.S.

Boston recorded 20 cm of snow with more than 60 cm falling in other parts of New England before the system headed to the Maritime Provinces and Newfoundland.

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.

Colorado Low impacts Maritimes

A Colorado Low tracked through the Maritimes today bringing mixed precipitation and strong winds.

The system brought the first major snowfall to Nova Scotia with 23 cm at Halifax Stanfield Airport and lesser amounts in the city but it caught drivers and plow operators off guard creating gridlock.

About 10 to 20 cm of snow also fell in central and southwestern New Brunswick where some schools closed with slippery road conditions.

Greater Moncton had a rain/snow mix this morning with 2 cm before it changed to rain.

As this system moves off to Newfoundland, brisk winds behind it will produce gusts up to 90 km/h with snow squalls expected along coastal areas.

Sharp drop in temperature!

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.

Heavy, wet snow creates chaos

Some drivers were prepared when snow entered the forecast for the first time this week and had their winter tires installed.

But many drivers were caught off guard by the heavy, wet – sloppy – snow which fell across Southern New Brunswick, Prince Edward Island, northern Nova Scotia and southwestern Newfoundland.

A low pressure system brought rain on Thursday but snow fell by evening as the temperature dropped to the freezing point.

The snow continued throughout Friday creating slippery roads which left plow operators scrambling to deal with the early blast of winter.

Many minor accidents were reported with vehicles sliding into the ditch.

The Trans Canada Highway at Cobequid Pass was forced to close for several hours Friday night after numerous tractor trailers got stuck in snow and blocked the road.

Snowfall amounts (Thu-Fri) in cm:

  • Corner Brook 19.4
  • Greater Moncton 18.8
  • Fredericton 10-15 (estimate)
  • Deer Lake 13
  • Saint John 8.9
  • Halifax Stanfield 5.8
  • Charlottetown 3.9

First snow of the season

Snow
A low pressure system moving through the Maritimes brought the first snow of the season to Southeast New Brunswick today.

A cold rain eventually turned to snow in Greater Moncton and 7.2 cm fell with Environment Canada calling for up to 10 cm tomorrow.

As the above chart shows, the first measurable snow in the region is typically recorded from late October to late November.

Tire shops have reportedly been busy this week as drivers scramble to get their snow tires installed.

October 2019 – Gradual easing into fall

Centennial Park, Moncton, 14 Oct 2019 (Dearing)

Daytime highs were consistently in the mid-teens in Southeast New Brunswick during October which usually sees a sharp drop in temperature as the month progresses.

The average temperature was 0.7°C above normal in Greater Moncton with two days failing to reach 10°C and the warmest maximum on the last day, 19.3°C.

Six days had lows below freezing with some light frost but there was no hard freeze allowing vegetation to flourish.

The precipitation total mostly came from five rainfall events with not a single snowflake recorded.

Fall foliage peaked prior to Thanksgiving weekend and several strong wind events left few leaves on trees by Halloween night.

A Blustery Halloween!

Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.

A low pressure system could bring at least 30 mm of rain to Southeast New Brunswick over the next 24 hours.

Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.

Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.

Forecasters say the wind may cause damage to buildings such as to roof shingles and windows.

The wind may not die down until early Saturday.

Fading tropical storm batters Ontario

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.

Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.

Wind gusts were up to 80 km/h in some locations with a peak of 104 km/h recorded at Port Colborne on Lake Erie.

Olga formed in the Gulf of Mexico several days ago and made landfall in Louisiana before quickly churning northward toward the Great Lakes.

Forecasters are calling for more wet weather and cooler conditions by Halloween.
