The three coldest spots in Nova Scotia this morning were Parrsboro at –18.8 C, Nappan at –16.8 C and the Halifax Stanfield International Airport at –14.1 C.
While it won't be as cold tonight, most of the province can expect low temperatures near –10 C. After that, temperatures will be much more moderate.
The cold air, which was brought in by north and northwest winds, also kicked up snow showers and squalls in very localized bands around the North Shore of the mainland and in Cape Breton's Inverness County.
Those bands of snow will still be around this evening and if you drive into one, your visibility will be greatly restricted.
There is also the possibility of slippery accumulations on the roads. Be cautious if you're driving along Highways 6, 104, 4, 19 and the Cabot Trail today and tonight.
Low temperatures between –12 C and –8 C tonight will feel colder in west winds that will hold between 10 km/h and 20 km/h. Much of the province will see clearing skies tonight.
Tomorrow it will be mostly sunny, with a mix of sun and cloud. Isolated flurries are still possible in the northeast of the mainland and Cape Breton — though the more intense squalls should end overnight.
Temperatures will take a step up, with afternoon highs of –2 C to 2 C. For communities on the southwestern Atlantic coastline, it will be near 5 C.
