Thursday, October 29th 2020, 7:00 pm - It won't take much, but the city of Halifax is in line for potentially recording one of its snowiest October days on Friday.
When you look at the forecast and projected snowfall amounts, it doesn't seem like much across the Maritimes on Friday. But as the wet snow builds through inland sections of Nova Scotia, the city of Halifax could potentially snag a new record.
It's all courtesy of an upper level trough and the remnant moisture from Tropical Storm Zeta, which will track south of the region through Friday.
As the moisture from Zeta slides east, the northern edge of the storm will clip the southern Maritimes with a mix of wet snow and rain showers, as well as a very cold north wind.
A widespread 1-3 cm is forecast for parts of Nova Scotia, which doesn't sound like much, but could be enough to take out the last spot for top ten snowiest October days at Halifax Stanfield International Airport. On October 30, 2011, 3.2 cm was recorded at the airport.
"So it'll take just over three centimetres of snow to get your top-ten snowiest day on Friday," says Weather Network meteorologist Tyler Hamilton.
That's nothing compared to the snowiest October day ever recorded, which occurred on October 20, 1974 when over 51 cm fell. There was a strong low east of Cape Breton combined with a cold Canadian arctic high to the west, which helped to dump half a metre of snow on the region.
