An extended period of wet and windy weather over Atlantic Canada due to an atmospheric gridlock with a strong blocking pattern over the North Atlantic has held Newfoundland and parts of the Maritimes in a soggy slog of rain, snow, and high winds.
While it may look as though the low has passed through the region, an area of high pressure over Quebec, as well as another off of Europe’s coast, will pull the low back into Atlantic Canada—essentially making the system do a “U-turn.”
On it’s way back, however, in addition to continued rain and high winds across Newfoundland, the low will also be packing an icy punch aimed at Labrador.

Rain will begin along Labrador’s coast on Thursday, bringing freezing rain to the southern reaches of the province by Thursday night as temperatures drop.
The icy conditions will reach as far as Happy Valley-Goose Bay and the Churchill Falls area.
There is also a chance for the freezing rain to sink southward overnight Thursday into parts of the Gaspé Peninsula and northern New Brunswick.
While the freezing rain is expected to finish early Friday afternoon for northern New Brunswick, it will continue throughout the entire day in Labrador before transitioning into snow Friday night.
The snow will last through Saturday, with 15-25 cm of accumulation expected in and around Churchill Falls and 10-15 cm in Labrador City.
The icy conditions will make any untreated surfaces slippery, so drivers are urged to use caution when out on the roads.
Freezing rain warnings have been issued in Labrador along Highway 500, between Churchill Falls and Happy Valley-Goose Bay, as well as for Highway 520 and parts of Highway 510.
Warnings have also been issued for parts of the Gaspé Peninsula.

The wet pattern across the rest of Atlantic Canada won’t be going anywhere, unfortunately.
An additional 50-75 mm of rain can be expected to fall over parts of the Avalon and Burin Peninsulas through Saturday before the low tracks into northern Quebec.
Environment and Climate Change Canada issued rainfall warnings for the peninsulas, with localized flooding being the main hazard.
A couple more systems are expected to keep the rain going across Atlantic Canada into next week, but we could see dry conditions make a comeback by the end of next week.
