Winter storm warning for
Ottawa North - Kanata - Orléans upgraded from Winter storm watch
A wintery combination of snow, ice pellets and freezing rain on the way.
Colder air is moving into the region and will coincide with an approaching low currently over Illinois. Several centimetres of ice pellets are expected today for regions from Lake Huron towards Lake Ontario and will change to freezing rain later today or tonight. It may very well fall heavy at times. It should taper off by Friday morning with temperatures rising above freezing. Of greater concern is the risk of widespread power outages due to downed tree limbs and power lines from significant ice accumulation combined with northeast winds gusting to 60 km/h. There is a risk that this could be a major ice storm.
For regions east of Georgian Bay towards Eastern Ontario including the nation Capital region, snow mixed with ice pellets is expected to begin tonight and continue through much of Friday. The majority of the precipitation should be ice pellets with up to 10 to 15 centimetres expected. Freezing rain is also a threat for these regions, although is not expected to be as widespread as regions farther to the south.
