Hefty dose of snow for parts of Newfoundland as temperatures plummet

The record-breaking warmth that marked some of the past week has fled the Atlantic provinces, and in its place is a return to cooler air and a fall-like system that will impact the region differently depending on location. Though largely manifesting as rain for Nova Scotia and New Brunswick, much of Newfoundland is in for heavy snow, with the Avalon peninsula in for a few flakes as well. For a closer look at timing, impacts, see below.

WEATHER HIGHLIGHTS

  • Colder temperatures return to the region

  • System to bring rain for parts of the region Friday night, up to 20 cm of snow for parts of Newfoundland Saturday

  • Unsettled weather and temperatures for early next week, late-week cooldown

FRIDAY NIGHT/SATURDAY: RAIN FOR MARITIMES, SNOW PUSHES IN NEWFOUNDLAND

After pleasant, record-breaking warm temperatures earlier in the week, Atlantic Canada is back in conditions better suited to the season, with a low-pressure system bringing a cold rain to Nova Scotia and southern New Brunswick beginning Friday evening.

By Saturday morning, the rain will have reached parts of the southern Avalon and Burin peninsulas as well.

However, most of the rest of the island will see the system's effects manifest as snow, at times heavy, particularly in central areas.

The Avalon Peninsula, particularly northern parts of it, is in line for lesser amounts, but still noticeable accumulations in the 5-15 cm range, whereas the extreme southern reaches of the peninsula are likely to see negligible amounts, if any.

In fact, the south of the peninsula will see rain or a rain/snow mix through most of the morning and afternoon, not really seeing the transition to wet snow until the evening.

BEYOND: UNSTABLE TEMPERATURES, ANOTHER SYSTEM

Sunday will feature something of a break for the region, but sea-effect snow will linger in the morning across eastern Newfoundland. However, the Colorado low moving through Ontario and Quebec will make its way into the Martimes Sunday evening and into Newfoundland by Monday morning.

Because of anticipated warmer temperatures then, most of the precipitation will fall as rain, but will start as snow in Newfoundland.

The low will bring about 10-15 mm of rain to the Maritimes and up to 10 cm of snow in the long-range mountains across Newfoundland, with much less in central and eastern areas because of the temperature rise and rainfall expected.

Strong winds are likely across Newfoundland, as well, with gusts of 60-90+ km/h.

That brief gasp of milder weather will be short-lived: Much colder weather will return for the middle and end of next week. Sea-effect snow is expected in western areas of Newfoundland and Cape Breton. Forecasters will also keep an eye on a system that could clip the Avalon mid-week.
