Closely watching the track of an East Coast-bound late-winter storm

Just as the last days of winter slowly tick down, forecasters are keeping a watchful eye on a system that looks to bring significant rain, snow, and gusty winds to parts of Nova Scotia and Newfoundland to cap off the week. Presently, heavy snow is possible for parts of central Newfoundland and eastern Nova Scotia, but the track is not quite certain yet, and there's a sharp temperature contrast to consider as well. What we know so far, here.

WEATHER HIGHLIGHTS:

  • Low-pressure system moves into Atlantic Canada later Thursday, starting as rain, but transitioning over to snow as colder air presses in

  • Snow continues across Nova Scotia on Friday, while Newfoundland sees a sharp temperature contrast with heavy rain for the Avalon

  • Brief shot of colder temperatures in the wake of the system before warming trend later in the weekend

THURSDAY THROUGH FRIDAY: LATE WINTER STORM TAKES AIM AT ATLANTIC CANADA

A late winter storm will take aim at Atlantic Canada to end the week, as a developing low pressure system offshore will push moisture back into the cold air that will be pressing in across the region.

Precipitation will start as rain late Thursday, but will begin to change over to snow overnight as the cold air spreads through.

"Snow may become heavy across Nova Scotia through the pre-dawn hours and into the morning on Friday, though depending on exactly where the temperature boundary sets up, a period of ice pellets and freezing rain will be possible along the south coast," says Weather Network meteorologist Michael Carter.

The snow will continue into the afternoon hours for Nova Scotia, while Newfoundland sees a sharp temperature contrast, with heavy rain expected for the Avalon and snow continuing to the west across the island.

"If possible, storm drains should be cleared before Thursday night, as a combination of rain, snow melt, and runoff will likely lead to minor flooding in areas where pooling water cannot drain properly," advises Environment Canada in a special weather statement covering most of Nova Scotia.

Conditions will gradually clear across Nova Scotia by Friday evening, while St. John's may see a period of freezing rain or ice pellets before ending as a bit of snow. As temperatures fall back below freezing Friday night, conditions will likely become icy as well.

Exact snowfall totals will depend on the track that the system takes, as well as the timing of the changeover from rain to snow. A swath of 10-15 cm is possible across parts of Nova Scotia, with higher amounts likely for central Newfoundland.

"In the wake of the system, we'll see a brief shot of colder temperatures, followed by a warming trend later in the weekend and through early next week," Carter adds.
