Environment Canada's forecast for the next five days for the St. John's area.
St. John's, the Avalon Peninsula and the Burin Peninsula are expected to get more snow Friday, just one week after the first major snowstorm of the season.
However, according to the latest forecast, snowfall amounts are expected to be less than last week's storm.
Environment Canada has issued a special weather statement which says a low pressure system currently developing over the Southeastern United States will move off the Eastern seaboard near Cape Hatteras tonight and then intensify as it tracks northward to cross the Grand Banks Friday night.
Snow associated with this system is expected to reach parts of the south coast Friday morning and spread over most of the Avalon by early Friday afternoon and continue into Friday night.
Environment Canada says it will be a fast-moving system and the snow is expected to end by midnight Friday.
Snowfall accumulations are expected to remain below warning criteria with highest amounts near 10 cms for the southern Avalon.
The weather agency, however, says the system is in the early stages of development ad there's some degree of uncertainty regarding how it will evolve. "A slight shift in the system's track could have a significant impact on anticipated snowfall accumulations."
Environment Canada is also warning that extreme wind chill values are expected in the Northern Peninsula east region and parts of Labrador.
It says a cold front will sweep across Newfoundland tonight and, in its wake, a brisk westerly flow of Arctic air will settle in over the province. Gusty winds and very cold temperatures will combine to create extreme wind chill values beginning tonight and persisting into Friday.
In the Northern Peninsula east region, extreme wind chill values near minus 35 are expected tonight and Friday morning.
In Labrador, extreme wind chill values of minus 45 to minus 50 are expected in some areas, including Labrador west, Churchill Falls, Upper Lake Melville, Eagle River and along the coast from Cartwright to Black Tickle, Rigolet, Postville, Hopedale and Nain.
