Maniwakiis forecast to go from a Thursday high of5 C to an overnight low of30 C and hoverthere until Saturday morning.

On top of that, wind chill is expected to make it feel more like45.

The Pembroke, Ont., area has a similar forecast.

Ottawa, Gatineau andCornwall, Ont.,areexpected to feeljust a little less cold, with temperatures at or below30 C and wind chill making it feel closer to40.

Wind chill is expected to make it feel more like the mid30s around Kingston and Belleville, with temperatures in the mid-to-low20s.

It may get slightly warmer in the day before dropping again Friday night.

Frostbite can develop in minutes on exposed skin when it's that cold.

Health units are sharing warning signs of frostbite and how to dress for the weather, while communities such as Gatineau, Kingston, Ont.,and Ottawaare offering lists of places to warm up and resources for people without homes.

On top of the cold, there are snow squall watches for the region outside of the Kingston and Belleville areas,warning ofsudden whiteouts Thursday afternoon and early evening as the cold snap arrives.

Back above zero soon

For the weekend in Ottawa, Saturday's temperature should peak at about 14 C in the day and stay there at night. A wind chill estimate isn't available yet.

After that, it'llreturn to the mild temperatures that have been a hallmark of this autumn and winter, with daytime highs forecast at or above 0 C Sunday, Monday and Tuesday.

The lack of cold and abundance of snow has ledRideau Canal Skateway management to doubt it can open this weekend for the start of Winterlude.

If it doesn't open Thursday, and that seems quite unlikely, it will be the skateway's latest opening ever.
