Temps do a bit of roller-coastering as the week draws to a close!

By Eddie Sheerr·

Wednesday brought quieter weather across Newfoundland and Labrador, and there’s nothing wrong with a calm stretch this time of year. That relatively settled pattern continues through Thursday, but changes are on the way as we head toward the end of the week.

Satellite and radar imagery Wednesday afternoon showed a sharp cloud boundary west of Labrador City and Wabush — a cold front separating milder air to the east from colder air pushing in behind it. Southerly and southwesterly winds ahead of the front helped boost temperatures slightly compared to recent days, while much colder air remained locked in over central and western Canada.

Overnight into Thursday morning, some light rain and snow will develop over parts of western Newfoundland, mainly inland and over higher terrain with respect to the snow. While most coastal areas will see little accumulation, elevated regions — particularly through Gros Morne National Park — could see more meaningful snowfall. Snow tapers off by early Thursday morning, though another round of light snow moves into western Labrador later Thursday evening.

Friday Morning Weather Update — December 19, 2025: forecast graphic 3

Temperatures overnight will either hold steady or rise slightly across the Island, while falling sharply in Labrador West. Lows on the Island will be near or above freezing. Labrador West falls into the minus teens overnight.

Thursday highs range from near 6 °C in St. John’s to well below freezing across Labrador, with Labrador City staying near –16 °C.

Looking ahead to Friday and Saturday, the overall weather pattern becomes more amplified — a sign of a stronger, more mature low-pressure system moving through Quebec and into Labrador. Instead of tracking east of Newfoundland, this system cuts inland, allowing much warmer air to surge northward. The result will be a widespread thaw across much of the Island and parts of Labrador.

Temperatures will rise significantly, especially in central and eastern Labrador, with highs approaching 7 to 9 °C in some areas by Saturday. This thaw is expected to last roughly 48 hours before colder air rushes back in later Saturday, potentially leading to a flash freeze in parts of Labrador West.

By Saturday evening, a cold front sweeps eastward across most of Newfoundland, changing any rain back to snow and triggering onshore flurries or snow squalls. Sunday and Monday trend cooler province-wide, with another chance of rain or snow developing for eastern Newfoundland early next week.
