Unsettled Weather Continues as Atlantic Low Drives Snow Across Newfoundland and Labrador
Today’s forecast highlights:
An area of snow will move away from northwestern and central Newfoundland and into northeastern areas of the Avalon Peninsula, specifically the northern half of the Avalon. Steady snow will end Tuesday morning, but light snow and flurries, and even pockets of drizzle will linger into the evening.
Snowfall amounts will generally be 5 to 15 cm, with the highest amounts being over inland areas and over higher terrain.
Flurries and drizzle will be found along the coast of central, Green Bay - White Bay, the GNP and coastal Labrador on Tuesday and even Wednesday.
Wind speeds will pick up a bit tomorrow and gust to 60 to 70 km/h over the Avalon Peninsula and the northeast coast.
An area of low pressure will move over the Island on Thursday, bringing more snow. While amounts don’t look overly heavy, it does look like a widespread 10 to 20 cm is on the way.
That low stalls north of the Island on Friday and will shift the weather toward coastal Labrador and the West Coast of Newfoundland (e.g., more snow).
At this point, the weather looks to improve for the weekend.

If you’ve been watching the waves along the coast today, you’ve probably noticed just how energetic the ocean looks. While conditions at places like Middle Cove were impressive, the larger story is what’s happening offshore.
A large and slow-moving low pressure system in the North Atlantic, well east of Newfoundland and Labrador, is responsible for the unsettled weather we’re dealing with now — and it’s going to continue influencing conditions over the next couple of days.
Snow Spreading Across the Province
As we moved into the evening hours, satellite and radar imagery showed a broad plume of moisture streaming toward the province. Much of that moisture is falling as snow, with some areas seeing a mix with freezing rain, particularly over parts of eastern Newfoundland.
Snow has already been falling across:
Coastal Labrador
Central Newfoundland
The Northern Peninsula
Northeastern and eastern sections of the island
The heaviest snowfall so far has been concentrated in Green Bay, White Bay, and Bay of Exploits, where Environment and Climate Change Canada has issued a snowfall warning. Some inland and higher-elevation areas could see 20 cm or more, while coastal sections are more likely to land closer to 10 cm.
Outside of that warned region, snowfall over the next 24 hours is expected to be impactful but below alert criteria for most areas.
Timing: When the Snow Falls
After midnight: Snow becomes more widespread and steadier, especially from the Bonavista Peninsula through central Newfoundland and toward eastern areas.
Overnight: The heaviest snowfall favors northern and inland locations, with lighter, wetter snow closer to the coast.
Tuesday morning into midday: Snow continues for the Avalon and Bonavista regions before tapering off in the afternoon.
Tuesday evening: Snow redevelops for parts of coastal Labrador, with flurries lingering elsewhere.
Elevation will play a big role. Higher terrain — especially inland areas — is likely to see higher totals than immediate coastal locations, where snow may be wetter and more compact.
How Much Snow Are We Talking?
From now through Tuesday evening:
Up to 5 cm: Coastal Labrador and some southern sections of the island
5–15 cm: Central Newfoundland, parts of the Bonavista region, and inland areas north of the Avalon
Locally higher amounts: Elevated inland terrain, particularly north and west of central Newfoundland
Southern coastal regions will generally see lower totals, while northern and inland locations pick up more.
Wind, Temperatures, and Wind Chill
Snow won’t be the only thing to deal with. Winds will increase Tuesday afternoon, with gusts of 60–80 km/h in some areas, making it feel colder and reducing visibility at times.
Overnight temperatures: Near –1°C for much of the island
Tuesday highs: Around +1 to +2°C
Wind chills: Down near –7°C overnight
Looking Ahead
Flurries and light snow will linger into mid-week for many areas. Another system arrives Thursday, though at this point it does not appear to be a major snowfall producer. Conditions gradually quiet down as we head toward the weekend, with milder air slowly working back in.
I’ll have my next update posted tomorrow morning!
