Thunderstorms cool off Eastern Canada

Thunderstorms rolling across Southern Ontario and Southern Quebec this weekend brought an end to oppressive heat and humidity.

Toronto residents were trying to keep cool Saturday when the mercury soared to 33.0°C with a stifling humidex of 44 and Montreal reported similar conditions.

In the Maritimes, even typically cooler coastal areas were warm with new record highs set in Saint John and Grand Manan.

The temperature in Greater Moncton peaked at 32.4°C which fell short of the record of 33.5°C from 1991.

A brief, violent thunderstorm hit Halifax on Sunday afternoon with flash flooding and strong winds knocking out power to more than 44,000 Nova Scotians.

Hottest weather yet?

The next heat wave across Eastern Canada could be the warmest period yet this summer with daytime highs in the low 30’s C and humidex values near 40.

Southern Ontario and Southern Quebec have been blanketed with heat warnings from Environment Canada with hot, humid days and warm nights expected this weekend.

Temperatures in the Maritimes for Saturday and Sunday could reach 30 C but a cold front will bring cooler and drier air by Monday.

A mini heat wave already brought highs of 29 C and 30 C earlier this week in Greater Moncton.

Lots of rain, freezing rain and ice pellets have been recorded so far this year in Southeast New Brunswick but snow has been somewhat scarce – until today.

A Colorado Low made its way across the continent this week bringing lots of snow to the American Midwest, Southern Ontario and Southern Quebec before arriving in the Maritimes.

Greater Moncton received 26 cm of snow followed by ice pellets and some freezing rain/drizzle along with strong winds which created poor visibility.

Snowfall amounts were fairly consistent across most of Nova Scotia with 22 cm at Greenwood and Halifax Stanfield Airport, 21 cm in Sydney but only 11 cm in Yarmouth.

Environment Canada says cold weather will replace the snow for late week with a brief warmup and rain expected this weekend.

First snowfall warning for Southeast N.B.

While other parts of New Brunswick have already had significant snow this fall, the first snowfall warning of the season has been issued for Greater Moncton and the Southeast region.

Fresh from impacting Southern Ontario, Southern Quebec and the U.S. Northeast, Environment Canada says this storm will bring up to 15 cm of snow with ice pellets and rain mixing in before tapering off later tonight.

Schools were cancelled in anticipation of the storm with snow beginning to fall by midmorning.

Prince Edward Island and Cape Breton Island are expecting 15 to 20 cm with lesser amounts for mainland Nova Scotia.

Strong winds across Atlantic Canada

A fast-moving cold front passed through the Maritimes today on its way to Newfoundland.

Powerful winds developed as a result which knocked out electricity to tens of thousands of customers across New Brunswick, Prince Edward Island and Nova Scotia.

The Greater Moncton International Airport recorded a gust of almost 90 km/h late this morning with Cape Breton Island reporting winds of more than 100 km/h.

Many locations across Newfoundland had hurricane-force gusts including Bonavista at 126 km/h, Wreckhouse at 107 km/h and St. John’s at 104 km/h.

The cold front also affected Southern Quebec yesterday with gusts of more than 80 km/h in Montreal and Quebec City.

Tornadoes tear through Ottawa

Environment Canada has confirmed two powerful tornadoes ripped through west end Ottawa before touching down again in Gatineau across the Ottawa River.

Officials say dozens were hurt and at least two residents are in hospital with critical injuries.

Tens of thousands were left without power after at least 80 utility poles either snapped or were damaged.

Meteorologists say severe thunderstorms spawned one twister classified as an EF-3 with winds up to 265 km/h while another tornado was an EF-2 with winds up to 220 km/h.

Tornadoes are not uncommon in Southern Ontario but storms of this strength are rare.

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.

A slow moving low pressure system brought a wintry mix of snow, ice pellets, freezing rain, rain and strong winds to Southern Ontario and Southern Quebec over the weekend.

Icy conditions led to more than 1,600 highway crashes, numerous power outages from falling trees and downed lines, cancelled flights, transit delays and school closures.

Officials were forced to close the CN Tower due to falling ice from the structure.

Here are some totals from the spring storm as of 16 April at 2pm EDT:

  • Toronto Pearson Airport – 18 hours of ice pellets, 6 hours of freezing rain, 12 cm ice pellets.
  • Toronto Billy Bishop Airport – Peak wind gust of 96km/h

Greater Moncton experienced its shortest day of the year with 8 hours and 37 minutes of daylight.

The winter solstice occurred at 12:28pm in New Brunswick marking the point where the direct rays of the sun begin moving north from the Tropic of Capricorn to the Equator.

North of the Arctic Circle, the sun does not rise at all today.
