An area of low pressure intensify rapidly overnight into Tuesday as it moves from near Nova Scotia to just north of Newfoundland. This low will bring snow, high winds and high waves as it affects Newfoundland and southeast Labrador over the next 24 hours or so.

So far as timing goes, it looks like the majority of the snow we see on the Island will fall overnight and be done with by 8 or 9 AM Friday morning. Most areas will see around 10 to 15 cm of snow, with some higher lollipops south and west. The snow will persist on the Northern Peninsula and southeast Labrador through the day, and that’s where the highest amounts will be found. I wouldn’t be surprised if a few spots in that areas see near, or over, 30 cm of snow.

Snow squalls will develop Friday across southern and eastern areas of the Island, including on the entire Avalon Peninsula and Burin Peninsula. The snow squalls will be very intense and may drop several centimters of snow on the affected area over a short period of time. Keep in mind that snow squalls affect small areas, so forecasting exact snow amounts from them is very difficult, but places that see persistent squalls could see significant accumulations.

Winds across southeast Labrador and most of Newfoundland will pick up drastically overnight and stay up through Friday and into Friday night. Gusts nearing, or exceeding 100 km/h will be common. Scattered power outages from the high winds are a good bet.

In the St. John’s area, the winds will likely be highest in the afternoon and evening, which is when winds will be sustained near 70 km/h with gusts nearing 100 km/h. The winds will calm down for all areas by Saturday morning.

Saturday we catch a break, although it will be chilly across NL. The next weather maker to arrive will come in Saturday night and linger through Sunday. This will bring snow and rain to the Island, along with temperatures nearing 10! Labrador will see more snowfall.
