Tonight into Saturday: Snow, Rain, and Drizzle
Overnight temperatures will drop to between -5°C and -10°C in Labrador, while most of the island falls to around -3°C to -7°C.
Snow arrives in western Labrador late this evening, spreading eastward and onto the island late tonight or early Saturday morning.
Labrador: Snow through much of the day Saturday with temperatures near or below freezing.
Island: Temperatures above freezing across southern, eastern, and parts of central Newfoundland, leading to a mix of snow, rain, and drizzle.
By midday Saturday, snow will be ongoing across much of Labrador, while the west coast of the island sees snow or rain. Central and northeastern areas will see light to moderate snowfall, while the Avalon, Burin, and South Coast quickly change over to rain.
As the day progresses:
Snow tapers off in central areas, ending as drizzle by evening
Rain ends in eastern areas
Snow continues along the west coast, Northern Peninsula, and across much of Labrador into Saturday night
Most areas will see improving conditions early Sunday morning.
Snowfall Amounts
This is not a major snowfall event for most communities.
Labrador: Generally 5–15 cm, with locally higher amounts in higher terrain
Island: Many areas receive up to 5 cm
Northern Peninsula, West Coast, inland South Coast: 5–15 cm
Higher elevations will see significantly more snow. For example, parts of Gros Morne National Park, northwest of Deer Lake, could see 25–40 cm by Sunday morning, mainly at elevation.
Sunday: Brief Break
Sunday brings a temporary break in the action.
Labrador: Highs between -6°C and -17°C
Island: Near 0°C to -4°C
Enjoy the calmer weather — it won’t last long.
Sunday Night into Monday: Potent Winter Storm
A much stronger winter storm moves in Sunday night and persists into Monday and Monday night.
Expected impacts:
Snow changing to ice pellets and rain for southern, eastern, and parts of central Newfoundland
Mostly snow, heavy at times, for western Newfoundland, the Northern Peninsula, and southeastern Labrador
Snow arrives Sunday afternoon or evening on the southwest coast, spreading north and east overnight. Even eastern Newfoundland will likely see some snow before a rapid changeover.
High Winds a Growing Concern
As this system passes north and east of the island Monday into Monday night, very strong winds are possible.
Gusts may exceed 100–120 km/h
Most at risk: South Coast, Avalon Peninsula, Northeast Coast, and parts of coastal Labrador
Exact locations will be refined over the weekend.
Once the main snow ends, onshore snow squalls and intense flurries are possible Monday night into Tuesday for western Newfoundland, the Northern Peninsula, Burin Peninsula, and Avalon.
Why So Much Snow-to-Rain Lately?
The jet stream pattern is to blame.
A persistent ridge over the North Atlantic is forcing storms to intensify south of Newfoundland and then track north instead of moving east. That keeps much of the province on the warmer side of these systems, leading to messy precipitation types rather than clean snow events.
There are signs this pattern may shift later in the month, but confidence is limited.
