Colorado low to impact areas from Manitoba to Newfoundland

A Colorado low will impact areas from Manitoba to Newfoundland in the coming days.

Manitoba

Snow begins this afternoon and will continue until Thursday morning across southern sections of the province.

Southeastern areas and the Red River Valley could see 15 to 30 cm of snow from this event.

Winds are expected to gust to 70 km/h which will result in blowing snow and reduced visibility.

This storm will cause significant travel disruptions.

Ontario

Heavy snow is expected.

15 to 25 cm of snow is expected across Northwestern Ontario, north of Lake Superior, portions of far northern Ontario, and northern portions of northeastern Ontario by Thursday morning.

Southern portions of northeastern Ontario and portions of eastern Ontario will see freezing rain on Wednesday before a transition to rain. Ice accretion could be from 5 to 10 mm in the Ottawa and North Bay to Sudbury followed by 20 to 40 mm of rain Wednesday afternoon into Wednesday night.

Similar rainfall amounts are expected across southwestern and south-central Ontario including Kingston to Manitoulin Island.

On Wednesday parts of southwestern Ontario will see thunderstorms with the possibility of strong winds and hail. Some thunderstorms could become severe.

Portions of far northeastern Ontario will see another 10 to 15 cm of snow on Thursday.

This storm will cause significant travel disruptions.

Quebec

Snow, ice pellets, and freezing rain are expected across Southern Quebec on Wednesday and Thursday.

Some southwestern and central areas will see an extended period of freezing rain. This will result in some locations receiving 10 to 15 mm of ice accretion. Power outages and tree damage are possible.

This storm will cause significant travel disruptions.

Atlantic Canada

Across most of New Brunswick and Nova Scotia, it appears as though ice pellets and freezing rain is expected from Wednesday night to Thursday morning.

On Thursday night and Friday, a similar event is expected in Newfoundland.

As this is still a couple of days out, it remains too early to provide precipitation amounts.

This storm has the potential to cause significant travel disruptions.
