Cool temperatures into early next week followed by a warming trend later next week; Some rain (patchy fog) at times through Saturday; Isolated showers Sunday

6:03 PM Friday, September 23, 2022

*Upper level troughing and northwest flow aloft will help keep a cool air mass in place across the Northland over the next several days. Daytime highs will range from the mid 50s to low 60s Saturday with slightly warmer temps Sunday with highs in the low to mid 60s, but then a reinforcing shot of cool air arrives Monday and Tuesday with highs in the 50s, but there is a chance that temperatures will warm to around 70 in parts of the Northland by later next week.

*Warmer overnight lows are expected this weekend, but colder temperatures with a chance for a frost/freeze are increasing for early next week, with next Tuesday morning and Wednesday morning having the greatest potential for widespread frost in the Northland the way it looks now.

*Expect some rain tonight into early Saturday morning followed by scattered showers during the day Saturday, with isolated showers Sunday.

*Sunshine will be scarce Saturday, but a little more sun is likely on Sunday.

The center of Fiona will approach Nova Scotia later today, move across Nova Scotia and into the Gulf of St. Lawrence on Saturday, then move across Labrador and over the Labrador Sea by late Sunday.

Fiona is a category 3 hurricane with gradual weakening forecast during the next couple of days, but Fiona is expected to be a powerful hurricane-force cyclone when it moves across Atlantic Canada.

Snow with a hurricane?

Why yes, there will be some snow in the colder air on the NW side of Fiona Saturday into early Sunday. This snow will mainly impact parts of eastern Canada. Pretty crazy!
