Newfoundland Forecast Updated Thursday, December 19, 2024 @ 8:00 PM

TONIGHT’S FORECAST

A low northeast of the Island will quickly track into the North Atlantic, while an associated cold front moves across eastern Newfoundland. Rain in the east will end by midnight, while a mix of snow and rain in central Newfoundland will also end by midnight. However, on the west coast and Northern Peninsula, onshore winds will produce flurries and snow squalls this evening, that will taper off before morning. A general 2-4 cm is likely, especially north of the Port au Port Peninsula, but 5-10 cm is expected in Gros Morne. Lows overnight from -3°C to +2°C on the South Coast and all 3 eastern peninsulas. Elsewhere, -5°C to -10°C. Winds shift to the west across the Island tonight, with gusts up to 50 km/h, which will diminish towards morning.

FRIDAY’S FORECAST (December 20)

The calm before the storm. High pressure will give a mix of sun and cloud with a chance of morning flurries on the northeast coast/Bonavista Peninsula. Temperatures do not move much from the morning lows. Generally light winds.

Friday night, a frontal system will approach from the south. Precipitation will start after midnight, but should cover all areas by mid-Saturday morning. 

SATURDAY’S FORECAST (December 21)

With the exception of a bit of snow and/or ice pellets and/or freezing rain at the start, the Burin, Bonavista, and Avalon Peninsulas will just see rain, and quite a bit of it too. For central NL, the west coast, and southern NL, snow will change through a long period mix of freezing rain and ice pellets, and eventually to rain or drizzle later in the day. Heavy snow moves into southeast Labrador late Saturday too.

If you have any flights for Saturday, delays and/or cancellations are possible, if not likely. Strong winds are also expected across Newfoundland with gusts of 60-90 km/h. Temperatures reach the double digits in eastern NL. I would highly suggest that if you have driving plans in Newfoundland for Saturday, postpone them or go tomorrow. Eastern Newfoundland should be fine outside of the RDF and high winds.

As for snowfall amounts, 5-15 cm is expected in southern and central NL, 10-20 cm on the west coast, and 20-30 cm on the Northern Peninsula through Saturday evening. Significant freezing rain is likely for inland areas of the entire Island, west of Terra Nova, so power outages and terrible driving conditions are expected.

Outlook

Significant snow squalls are likely up and down the west coast, including the Northern Peninsula, Saturday night and most of Sunday. Elsewhere, mostly cloudy with occasional flurries Sunday.
