Temperatures across the Province vary widely this afternoon. We are seeing well above normal temperatures on the Island, while the coldest air of the year is pressing southward from Labrador.

Many areas of Labrador are reporting snowfall right now; however, along the Straits, it’s likely a mix. And as of this hour, St. Anthony Airport is reporting freezing rain. This means the stationary boundary associated with the low is a tad farther east than forecast. As the afternoon progresses, that may not change much, and freezing rain may fall for several hours before the change to snow this evening.

Forecasts indicate that 5 to 10 mm of freezing rain is quite likely this afternoon, especially on the northern part of the Peninsula. This may require alerts from ECCC NL and could lead to localized power disruptions.

Good Monday morning!

A potent area of low pressure will bring a mixed bag of weather to the Province today, followed by a sharp cool down later today or tonight as the first bout of true arctic air of the winter moves in. The highlights of this weather-maker will be rain and wind over the Island today while heavy snow falls over the southeast quadrant of Labrador. The snow will mix rain ice pellets and freezing rain along the Labrador side of the Strait of Belle Isle.

The low will depart overnight and behind it the coldest air of the season will be ushered into the region. The incoming cold air will drive intense snow squalls that will first be seen on the West Coast of the Island early Tuesday but will quickly spread to the South Coast, Burin, and Avalon Peninsula during the day. The snow in these snow squalls will be locally intense, and travel across many of the areas mentioned will be locally challenging.

The Forecast

Monday’s Weather

Periods of rain over the Island with unseasonably warm temperatures. The rain will be heaviest this morning and will taper to showers this afternoon. There may even be some sunny breaks over eastern areas this afternoon! It will be breezy all day, but wind speeds will peak over the eastern half of the Island, with gusts of 80 to 100 km/h.

Snow will fly along the Labrador Coast through the day, and about as far west as the Churchill Valley. The heaviest will be near Cartwright, which is expected to be near 30 cm. Locally higher amounts are possible. Winter Storm conditions will also be found along parts of the coast as the wind ramps up this evening as the area of low pressure strengthens and departs.
