After a milder start to the week, things will end much cooler across parts of Atlantic Canada, with the threat for snow prompting special weather statements over eastern Newfoundland. This could be the first measureable snowfall of the season for the Avalon, with the potential for 5-10+ cm to fall. Forecasters are also watching the threat for a strong low early next week, which brings the threat for strong winds and heavy rain. More on the timing and impacts of these systems, below.
FRIDAY THROUGH SATURDAY: FIRST ACCUMULATING SNOW THREAT FOR EASTERN NEWFOUNDLAND
As cold air presses in across eastern Canada, an active storm track will develop along the Atlantic coast, which by the end of the week could bring the first taste of winter in the form of accumulating snow.
A system developing on Friday is what will provide the source of moisture, just as the colder air settles in over the region.
That in turn could bring a changeover from rain to accumulating snow for parts of eastern Newfoundland, including the Avalon Peninsula, late Friday night and into Saturday.
"Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate. Motorists should be prepared for winter driving conditions," says Environment and Climate Change Canada in the special weather statement.
Highest accumulations are expected inland and over higher elevations with rain expected near the coast before the precipitation tapers Saturday morning.
BEYOND: INCREASING POTENTIAL FOR SIGNIFICANT STORM EARLY NEXT WEEK
Forecasters are also keeping an eye on a significant storm early next week.
"A very strong low over the Atlantic should track close enough to the region to bring strong winds, heavy rain and mild temperatures," says Dr. Doug Gillham, a meteorologist at The Weather Network.
