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.

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.

The weather has been relatively calm lately in New Brunswick and the Maritimes which has been a welcome relief after a string of winter storms earlier this month.

Mild air has pushed into the region which set several record highs yesterday both here and in Southern Ontario.

The Greater Moncton International Airport reached 10 C and it was the warmest temperature since 18 December – just shy of the record of 13.2 from 1981.

But some weather stations in the Moncton area climbed as high as 13 C.

New record highs for 23 February:

Kouchibouguac Nat’l Park 12.4 C

Woodstock, NB 11.9 C

Bathurst 10.5 C

Windsor, ON 19.3 C

London, ON 18.3 C

Toronto Pearson Airport 17.7 C

A low pressure system passed over the Bay of Fundy today bringing the second major snowstorm of the season with at least 20 cm for Southeast New Brunswick.

Schools closed, flights were cancelled at the Greater Moncton International Airport and several car crashes reported as road conditions worsened throughout the day.

Precipitation started as snow in Nova Scotia but later changed to freezing rain and then to rain as temperatures climbed above freezing.

The same Colorado Low impacted Southern Ontario earlier today delivering 15-30 cm snow from Windsor to Ottawa including the Greater Toronto Area and Southern Quebec including Montreal and Quebec City.

Upwards of two months worth of rain has fallen in just a few days in a corner of Southwestern Ontario which includes Windsor and Tecumseh.

The normal September rainfall in the region is just under 100 mm with as much as 195 mm falling in some areas this week prompting a state of emergency.

Environment Canada says a strong and slow moving low pressure system brought heavy rain which led to flooding.

More than 1,500 Windsor residents reported basement flooding and many streets were inundated with water leaving vehicles stuck.

Tornadoes hit SW Ontario

Environment Canada has confirmed two tornadoes touched down in Southwestern Ontario Wednesday night (24 August).

The first one struck in LaSalle and another one hit nearby Windsor.

No one was seriously hurt but emergency responders assessed reports of trees toppling over and property damage.

The mayor of Windsor said at least 15 homes in the city were too damaged for residents to re-enter.

Sizzling September heat!

Hot, humid weather made a comeback in Southern Ontario yesterday with humidex values soaring near 45 in some areas.

Environment Canada reported new heat records were set at Toronto Buttonville Airport hitting 35.0°C, Windsor at 34.6°C and Collingwood at 33.7°C.

The hotspot was Sarnia at an unseasonable 35.9°C (almost 97°F).

Some of that heat filtered into New Brunswick today – St. Stephen climbed to 28.5°C with a humidex of 37 and even Moncton reached 23°C with a humidex of 31.

For many in Southern Ontario, this wintry wallop was the first major snowstorm of the season dumping about 15 cm of snow on Windsor, Toronto and Hamilton with 20 cm in Ottawa and 30 cm in Kingston.

Montreal could receive as much as 40 cm of snow while Quebec City can expect about 20 cm.

The storm actually originated in the American South dropping rare post-Christmas snow on cities like Dallas, Texas and Little Rock, Arkansas.

After hammering the U.S. Northeast with snow and rain, the storm is now moving into New Brunswick and Nova Scotia with snow, strong gusty winds and rain along the Atlantic coast.
