Atlantic: Temperatures drop in wake of system

Sunday, February 17th 2019, 9:26 am - Snow and rain continue for Atlantic Canada, which will then be followed by dropping temperatures as the system exits the region.

The system that is now exiting Atlantic Canada is leaving behind frigid conditions, which will cause widespread freezing for much of the accumulated precipitation. More on the timing of the incoming cold, as well as who is still seeing rain and snow, below.


WEATHER HIGHLIGHTS:

  • Rainfall lasts into Sunday morning for southwest
  • Southwest winds gusting 60 km/h through the day Sunday
  • Abrupt return to colder air into new week

WATCH BELOW: SNOW, RAIN TIMING

The system is finished with the Maritimes, but snow and rain is still in store for Newfoundland overnight.

Rainfall will be particularly noteable along the southern central shores of Newfoundland, where Burgeo could see accumulations between 20 to 40 mm before the rain diminishes overnight which could cause localized flooding in low-lying areas and possible washouts near rivers and creeks.

As the low pressure system that brought a brief rise in temperatures and rain for many exits the region, falling temperatures are left behind, which will freeze much of the accumulated precipitation from the previous days and make for slippery conditions on sidewalks and roads.

As the front passes the Avalon by Sunday morning, it will leave southwest winds gusting 60 km/h through the day.

A LOOK AT NEXT WEEK

While temperatures will surge for many on Saturday -- to well above seasonal values for much of Nova Scotia -- the warm up will be a brief one as much colder air returns in the wake of the system. Wind chills in the mid-teens will again be the trend by the early part of next week.

This round of cold air will at least come with periods of sunny skies stretching through much of next week. "An unusually quiet pattern is ahead for Atlantic Canada next week," says Weather Network meteorologist Dr. Doug Gillham. "Temperatures will be colder than seasonal, but we expect no significant systems."
