WEDNESDAY: HEAVY SNOW CLOSES SCHOOLS IN WESTERN NEWFOUNDLAND

As the rain and snow with the latest system winds down across the Maritimes, conditions deteriorated quickly in Newfoundland Wednesday morning, prompting some school closures in western sections of the province.

Rain, wind and winter storm warnings span the island with drivers being warned to postpone non-essential travel until conditions improve.

"Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow," Environment Canada warns.

Between 10-20+ cm of snow is expected in the hardest hit areas before a change over to rain and then a gradual tapering later in the day.

Strong winds will also be persistent with the threat for gusts up to 120 km/h over exposed coastal areas of the southern Avalon Peninsula.

Due to the weather conditions, the City of St. John's has postponed garbage and recycling, and Mount Pearl has cancelled its recycling collection as well.

THURSDAY: TEMPERATURES TAKE SIGNIFICANT PLUNGE

As the system departs, temperatures will drop considerably on Thursday as a brief burst of cold air from the Arctic will return. Temperatures on Thursday morning will be about 15-20°C colder across the region than they were early Wednesday morning.

The cold and blustery conditions could also stir up some sea-effect snow through the day on Thursday.

"The very cold weather continues into the weekend, then milder Pacific air spreads back into the region by early next week," says Weather Network meteorologist Dr. Doug Gillham, adding that the weekend will also be marked by a period of quieter weather.
