Right now: As of 5:48 this morning, temperatures are sitting just above the freezing mark across much of Newfoundland. It’s 3 in St. John’s, Marystown, Corner Brook and Badger, and 2 in Gander and Port aux Basques. Stephenville is right at 0. Coastal spots are a bit milder, with 4 in Burgeo, 5 in Bonavista and 6 at Cape Race. Labrador is colder. It’s -3 in Happy Valley-Goose Bay, with a wind chill near -8, and -1 in Nain. Wabush and Churchill Falls are at 0, and it’s 1 in Cartwright, Mary’s Harbour and St. Anthony.
It’s going to be a cooler day across the province today. Northerly winds have brought in cooler air overnight, and most of Newfoundland is starting the day under cloud, with a few showers or some drizzle around early this morning, mainly through central and eastern areas and on the West Coast. That clears out this afternoon, with more sunshine for most of the Island by the end of the day, although it will be cool, with highs of only 6 to 9. The south and southwest coasts get the best of it, with sunshine in Port aux Basques and clearing skies this morning on the Burin Peninsula.
Tonight, skies clear this evening and temperatures drop to near 0 to +2 for many areas before clouds move back in overnight. Along the southwest coast, there’s a chance of showers or drizzle and some fog patches overnight.
In Labrador, it’s a cold start, with wind chills near -8 in Goose Bay, Nain and Makkovik this morning. Skies are mainly sunny in Goose Bay and along the southeast coast, with highs near 6 to 7. Rain showers or flurries move into western and central Labrador this evening.
Then we turn our attention to the nor’easter, and it’s looking more significant than it did yesterday. Rain moves onto the Burin Peninsula around noon Thursday and reaches the Avalon in the afternoon, with 5 to 10 mm by evening. From there, it looks like we’re in for a significant weather event between late Thursday and early Saturday, with rain, wind and snow on Friday. The hard part right now is figuring out where the snow will fall. The models still disagree on the track, and the ECMWF model has more snow farther west than the others. Small changes in the track will make a big difference in who gets rain and who gets snow, so I’ll be watching it closely and will have a full update tonight.
Eastern Newfoundland / the Avalon: Mainly cloudy this morning, with a chance of showers or drizzle early around Clarenville, then clearing this afternoon. Highs 6 to 7. North winds 20 km/h, gusting to 40, becoming light this afternoon. A few clouds tonight, with clouds increasing overnight and lows near +1 to +2.

Looking ahead: The nor’easter is the big story for the end of the week. From late Thursday to early Saturday, it looks like a significant event for Newfoundland, with rain, wind and snow on Friday. The heaviest rain looks most likely on the Avalon and Burin Peninsula, while central and western areas, where highs are only 3 to 6 on Friday, are where snow is more likely. Exactly where the rain changes to snow, and how much snow falls, is still uncertain. The ECMWF model is farther west with the snow than the others, so if you’re in central or western Newfoundland, keep an eye on the forecast over the next day or so. Things improve from west to east on Saturday, with sunshine returning to western and central Newfoundland while showers linger in the east. Labrador stays quiet and turns milder by the weekend, with highs near 10 in Goose Bay by Saturday.
