After a breather, the next Atlantic storm is already on the horizon

The second in a messy one-two punch to hit the Atlantic region looks to make its first approach late Sunday after something of a break during the day. Its effects will last into Monday for most of the region, longest in Newfoundland, and will include overnight snows and/or ice pellets followed by a general switchover to rain through the day Monday. The most impactful weather story, however, will be the winds, which look to exceed 100 km/h Monday for many communities. For a more detailed look at what's ahead, see below.

WEATHER HIGHLIGHTS:

  • Next system arrives in the Maritimes late Sunday, continuing through Monday for the Atlantic region

  • Period of snow for much of the region, with ice pellets in Newfoundland, before largely changing over to rain for most areas Monday

  • Very strong winds Monday, exceeding 100 km/h for several communities

LATE WEEKEND INTO MONDAY: EYES ON THE NEXT MAJOR STORM THREAT

Though high pressure will keep Atlantic Canada's skies clear for most of Sunday, the next system looks set to arrive by the evening, with effects lasting well into Monday for most of the region.

The temperature differential will be such that a large swath of the Maritimes is likely to experience the system as ice pellets and a snowy start, particularly New Brunswick. By morning, however, the changeover to rain will be complete, with some 20-40 mm likely, heaviest in Nova Scotia and along New Brunswick's Fundy Shore.

Newfoundland will also experience part of this system as rain, with a large chunk of ice pellets over the island, with some very heavy amounts likely along the southern shores of the island.

Prior to that switchover, the region will see another round of snow, heaviest in northern New Brunswick and parts of Newfoundland, with much of southern New Brunswick and Nova Scotia beyond Cape Breton getting away with trace amounts, if anything.

Far more remarkable for people in the region will be the winds, which will be considerable and damaging as they trail behind the system as it passes through and exits the region.

Gusts look to reach or come very near to the 100 km/h mark for much of Nova Scotia and Prince Edward Island, peaking Monday morning and remaining strong for the rest of the day.

The winds will ramp up through the day in Newfoundland, reaching their peak in the afternoon and evening, slightly higher than in the Maritimes, with peak gusts of more than 110 km/h not out of the question.

Beyond, people can finally enjoy a breather, with a period of fair weather mid-week and temperatures trending on the milder side.

As for storms, forecasters are eyeing the late week, with a system that will bring mostly rain for the region, with heavy snow for Labrador and some potential for a period of snow in New Brunswick.
