58,000 without power in Quebec from wind and ice

While we were prepared for the worst, I was pleased to see mostly sleet (ice pellets) had fallen on Ile Perrot overnight, with very little ice accretion. Freezing rain is falling this morning, mixed with snow and ice pellets. Precipitation should taper of this afternoon. (ValleyWeather)
Over 58,000 Quebec homes and businesses are without power this morning after a night of freezing rain and strong winds. Most of the outages are in the Monteregie south of Montreal. The island of Montreal is in decent shape so far. We caught a huge break on Saturday, as mild air held on a few hours longer producing more liquid rather than frozen precipitation. Since the changeover around 10pm Saturday evening, most of the freezing rain has been mixed with ice pellets,which does not stick to trees or power lines. The wind has been gusting to 60km/h at times from the northeast.

Hydro Quebec has more than 100 teams on the road Sunday morning to restore power as quickly as possible. Power outages have also been reported in central and eastern Ontario. The precipitation is expected to continue through the middle portion of the day in Montreal, with another 10 to 15mm of freezing rain possible, especially south of the city. Some sleet and light snow will mix in as well. Conditions should start to improve later this afternoon. Winds will diminish as well by this evening. The temperature will remain nearly steady near -5C (23F) today in Montreal, dropping to -11 (12F) by Monday morning. 

The massive winter storm creating the heavy rain and ice in Quebec, stretched from Texas to Atlantic Canada. The system not only produced flooding rains in Ontario and Quebec, but heavy snow to the north and west of the track and deadly tornadoes to the south. Along the US east coast on Saturday, a surge of warm air generated by the same storm, resulted in over 60 record highs, some dating back to the 1890's.

The heavy rain Saturday produced plenty of localized flooding across the region. Montreal received a record breaking 44.2mm at Trudeau Airport, crushing the previous daily record of 18.6mm set in 2008. All that rainfall is now ice, with a current temperature of -6C (21F) in Montreal, down from Saturday's high of 7C (45F). If you head today be extremely careful as all surfaces are covered in snow and ice.
