An arctic front is sweeping across Newfoundland and Labrador tonight into Friday, bringing the coldest air of the season so far. This shift will be sharp — and fast — with temperatures dropping rapidly through Friday morning. Wind, snow, and snow squalls will all play a role.

Flash Freeze Risk Friday Morning

Temperatures fall hard behind the front. By early Friday morning, the cold is already entrenched in western Newfoundland and sliding eastward rapidly. Areas that start the day with rain will see a transition to snow as temperatures plunge below freezing.

This creates a flash freeze risk, especially late morning into midday for eastern and northeastern Newfoundland. Roads and surfaces that are wet early in the day may turn icy quickly.

Snow, Squalls, and Heavy Localized Bands

Snow sets up across:

• Northern Peninsula

• Central Newfoundland (periods)

• Southeast Labrador

• Western Newfoundland (snow squalls)

The most intense snow will fall:

• Northern Peninsula East / Red Bay–L’Anse-au-Clair region:
  ~20–30 cm (locally higher possible).

• Western Newfoundland (north of Corner Brook):
  Persistent squalls may push totals into the 10–30+ cm range, with 2 feet possible in the highest terrain over 24–36 hours.

• Northeast coast near and north of Gander:
  A narrow but potent band could produce 20–30 cm if it sets up inland. Slight shifts will determine who gets hit.

Most other areas see much lower amounts — this is one of those highly localized setups where positioning matters.

Powerful Winds Friday Afternoon & Night

A rapidly developing low northeast of Newfoundland will drive widespread high winds.

• West & Southwest Coast:
  Gusts 90–110+ km/h beginning mid-afternoon.

• South Coast / Burin / Connaigre:
  Gusts may exceed 120 km/h Friday evening.

• Eastern Newfoundland (Avalon, Bonavista, Clarenville):
  Peak gusts Friday evening through midnight. Many areas could exceed the 110 km/h threshold, with potential for higher bursts.

• St. John’s Metro:
  Late evening into the overnight — gusts near or over 105–110 km/h.

Any snow squalls overlapping these winds on the west/southwest coast could produce blizzard-like conditions.

Expect:

• Possible power outages

• Difficult travel

• Blowing snow / reduced visibility in squall zones

Wind Chill

Wind chills:

• Labrador West: mid –30s

• Most of Newfoundland: –10s to –20s

A bitter day across the board.

Saturday & Beyond

Saturday stays cold but quieter.
Labrador remains well below seasonal into next week.
Avalon/NL east also stays cold with a chance of snow again Tuesday–Wednesday.
