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.

A rapidly deepening low pressure system created strong winds gusting to hurricane-strength across Southern Ontario and Southern Quebec on Friday knocking down trees and power lines causing massive outages.

Three people were killed by fallen trees and a school bus filled with children in Mississauga had a near miss.

Toronto Pearson Airport had a maximum wind gust of 119 km/h while Montreal Trudeau Airport recorded 117 km/h – both are the windiest days ever in May.

Winds were also powerful on Saturday in Greater Moncton with a wind gust of 100 km/h – the strongest since January.

Storm coming to N.B.

StormComing18
Several weather outlets are forecasting a major winter storm will hit the Maritimes bringing heavy snow and strong winds to New Brunswick just days into 2018.

Blizzard conditions are possible along with large waves and high water levels along the coast.

Nova Scotia may get more rain along the Atlantic coast while a rain/snow mix is likely inland.

Until the storm arrives, Arctic air remains firmly in place with several cities in Ontario setting new record lows on New Year’s Day including -22.6 C at Toronto Pearson Airport and -28.6 C at Ottawa Macdonald-Cartier Airport.

While the province itself currently basks in warmth, an Alberta Clipper moved through Central Canada dropping the first snow of the season to many parts of Southern Ontario and Quebec.

About 12 cm of snow fell in Windsor, 10 cm at Toronto Pearson Airport and 16 cm in Ottawa.

Environment Canada is forecasting even heavier amounts for Quebec City with up to 50 cm expected.

The system also brought more than 30 cm of snow to northern New Brunswick with a mix of snow and rain in Greater Moncton.

Temperatures have felt more like January than November across Ontario as an Arctic air mass brought snow and record cold to many communities.

Both Toronto Pearson and Toronto Island Airports set new lows early Friday and early Saturday near -10 C which in some cases dated back to the mid-1800s.

Police warned drivers to slow down on highways which became slick with the first snowfall of the season.
