The view from my place earlier today said it all — steady, healthy flakes falling with more on the way for a good chunk of Newfoundland. As we move through this evening and into tonight, snow, wind, and even some intense snow squalls will be in play for different parts of the island.

Let’s break down what’s happening now, what’s coming tonight, and what to expect through mid-week.

Environment and Climate Change Canada has issued multiple weather alerts across Newfoundland, ranging from winter storm warnings to blowing snow advisories and snow squall watches.

Winter Storm Warning

Connaigre, Clarenville, Terra Nova, and the Bonavista Peninsula are expecting up to 20 cm of snow by Tuesday morning. Travel will deteriorate quickly this evening as that heavier snow arrives.

Blowing Snow Advisory

Surrounding areas — Gander, Bonavista North, Buckland’s, the interior, Burgeo–Ramea, the Bay d’Espoir region, Avalon North, and St. John’s — will see snow combined with increasing winds, reducing visibility at times.

Snow Squall Watch

For the west coast, including Corner Brook, Bay St. George, Port aux Basques, and Deer Lake–Humber Valley, intense snow squalls may develop tonight and persist into Tuesday. These could be strong enough to warrant expanded alerts further north.

Wind Warning

The Avalon Peninsula will see gusts near 100 km/h overnight. While this won’t match the extreme winds of last Friday, it will still be a rough stretch overnight with blowing snow, reduced visibility, and possible isolated outages.

How the Storm Plays Out

Snow is already developing across southern and eastern Newfoundland as a low intensifies to our south and pushes eastward.

Key timing:

• Avalon: Heaviest snow through early evening, then a break — possibly drizzle — before a second round of snow arrives after midnight.

• Central & Bonavista Bay: Heaviest snow between 7–10 PM, shifting northeast by late evening.

• Overnight: Snow tapers to flurries island-wide by 3–4 AM, except where squalls set up on Tuesday.

Winds peak between 11 PM and 1 AM on the Avalon with widespread gusts 80–100 km/h.

Tuesday: Snow Squalls Take Over

Colder air surges in behind the departing low, aligning the low-level winds — a perfect setup for long-fetch streamers from the Gulf.

Computer guidance suggests:

• A 600 km–long snow squall from east of Bonavista to Corner Brook

• A 225 km squall into the Burin and Avalon

• A 330 km streamer from Terra Nova toward Bay St. George

Where these bands anchor, snowfall could climb quickly in narrow corridors. Exact placement is notoriously tricky, so expect surprises along the west and southwest coasts.

Snowfall Forecast (Monday Night–Tuesday Morning)

• Clarenville / Terra Nova / Bay d’Espoir / St. Albans: 15–25 cm

• St. John’s & the Avalon: 10–15 cm (leaning toward the lower end but track shifts matter)

• Gander: 5–10 cm, with upside potential if flakes stay fluffy

• West Coast: 10–15 cm, though amounts will heavily depend on squall placement

• Northern Peninsula & most of Labrador: Minimal from this system

Frigid Tuesday Morning

Temperatures plunge following the evening warm-up:

• St. John’s: Near –11°C (feels colder with windchill)

• Island-wide: Mid minus teens for windchill values

• Labrador: Minus teens to twenties

Bundle up the kids for the bus stop — it’ll be a biting start to the day.

Wednesday: A Quiet Break

Wednesday brings calmer weather and slightly milder temperatures across the island. Labrador stays quiet but cold.

Thursday: A Big Pattern Shift

Another low tracks west of Newfoundland, putting much of the island into a warmer southerly flow. Expect:

• Milder temperatures

• Rain, not snow, for many areas

• More snow returning for Labrador later in the week

Final Thoughts

It’s a busy start to the week with multiple types of winter weather in play — snow, strong winds, and the potential for impressive snow squalls. Conditions will vary dramatically by region.

I’ll have more updates overnight and tomorrow morning in the Sheerr Weather app.
