After weekend ice storm, temperatures take a nose-dive.

Monday, January 5, 2015, 8:33 AM - A cocktail of rain, snow and freezing rain made Quebec's weekend travel a nightmare.

Aside from impossible roads, rain turning to ice on surfaces brought down trees and power lines, leaving more than 150,000 customers in the dark at the storm's height.

Hydro-Quebec workers whittled that number down to under 10,000 as of 8:30 a.m., mostly in the Montreal and Monteregie area, but the landscape is still coated in ice in many areas.

Temperature differentiation made for periods of snow, followed by periods of freezing rain, and in some cases back to snow in several places over the weekend.

In all, the Quebec City area got around 15 cm, which was about the upper limit of totals in various parts of Montreal, which also got a total of 15 mm of ice accretion from freezing rain.

Now the work-week has started, the new threat is extreme cold temperatures.

Unlike in neighbouring Ontario, Environment Canada has not issued special weather statements in southern Quebec, although areas a little further north will be feeling wind chill values of -45 in some places.

But the province's major cities will still be seeing their coldest temperatures of the season. Montreal's daytime high won't exceed -10^oC all week, and will feel colder than -20 until at least Friday, with Sherbrooke facing similar conditions.

Quebec City will be even colder, falling to a high of -22^oC by Thursday, feeling close to -30.
