Storm sweeps Ontario

Freezing rain coats trees in central Ontario, 30 Dec 2019 (South Simcoe Police)

Ontario is so large and sprawling that it’s rare one storm could impact most of the province but that’s what happened Sunday into Monday.

A large low pressure system brought severe winds to the southwest, hours of freezing rain in the east and heavy snow in the northwest.

Temperatures also soared briefly in the Greater Toronto Area with a new record high of 10.2°C set at Pearson Airport.

Freezing rain duration in hours:

  • Ottawa Int’l Airport – 22
  • Sudbury – 20
  • CFB Trenton – 18

  • Thunder Bay – 30
  • Atikokan – 18

Severe weather in Manitoba, NW Ontario

After a hot and windy day across southern Manitoba, severe thunderstorms developed late Friday afternoon with heavy rain, hail and lightning strikes causing at least one grass fire.

Daytime highs soared to 36.6°C in Winnipeg and 37.3°C in Carman which was the hot spot in Canada.

Temperatures dropped dramatically after the storms rolled through and damaging winds up to 100 km/h were reported in some areas along with nickel-sized hail.

The heat and thunderstorms moved east into northwestern Ontario with Kenora reaching 33.0°C yesterday and Armstrong climbing to 32.3°C today.

Weather bomb crosses the continent

Bomb cyclone

A so-called bomb cyclone brought blizzard conditions to Colorado and now heavy rain,  flooding and even tornadoes to the U.S. Midwest.

The weather bomb occurs when there is a rapid drop in atmospheric pressure over a 24 hour period.

Further north, the storm is dumping snow across Minnesota as it moves into northwestern Ontario.

Severe thunderstorm watches have been posted for Southern Ontario with strong winds expected along with heavy rain.

New Brunswick will the effects this weekend with significant rainfall and gusty winds in the forecast.

Warm in west, chilly in east

Most trees have now lost their leaves in Greater Moncton – with oak trees being the exception – and the starkness of November is settling in.

The thermometer dipped to a frosty -3.1 C yesterday morning which was the coldest low so far this fall and a chilly high of only 4.5 C.

It’s a different story in the Prairies and northwestern Ontario with record breaking warm temperatures climbing near 20 C which is well above normal.

Edmonton climbed to 20.6 C on Friday which was the warmest high ever for a November day in the Alberta capital.

Snow moves east

Snow in Kenora, ON, 05 October 2012 (TWN)

The snow that fell in British Columbia and Alberta earlier this week has moved east giving southern Manitoba and Northwestern Ontario quite a dumping.

While Winnipeg escaped the worst of the snowstorm, areas to the south and east got hit hard with as much as 30 cm of snow reported.

The heavy, wet snow brought down trees, many of which still have leaves, and power lines leaving thousands without electricity.

Environment Canada says moisture from the south collided with Arctic air from the north bringing the region an early taste of winter.

Snow in NW Ontario!

Snow in Dryden, ON,14 Sept 2011 (TWN)

The calendar says it is mid-September but that didn’t stop a little snow from falling over Northwestern Ontario today.

Temperatures were only a few degrees above freezing allowing a cold rain to become snow in communities like Dryden and Red Lake.

Having lived in the region for more than six years, I can say this is early for the first snow.

Although one year when I lived in Fort Frances, it snowed one centimetre on September 29th and again on September 30th.

Tornado touches down in NW Ontario

Environment Canada has confirmed a tornado touched down in Northwestern Ontario yesterday after reports of funnel clouds in several communities.

A tornado was spotted near Dryden Airport at 4:30 p.m. (pictured above) and northwest of the Sioux Lookout Airport at 5:40 p.m.

The tornado track was reportedly about 80 kilometres long over a remote area.

No structural damage or injuries have been reported.

Tornado warnings were issued across Northwestern Ontario yesterday as severe weather swept through the region.
