Winter storm watch for
Ottawa North - Kanata - Orléans continued
Significant freezing rain and ice pellets likely Thursday into Friday.
A series of low pressure systems will give periods of rain to many regions into tonight. On Thursday, a stronger low will approach from the southwest and combine with a colder airmass from the north. As a result, rain is expected to change to freezing rain and ice pellets late tonight or Thursday morning. Periods of freezing rain and ice pellets are expected to persist Thursday night into Friday and be heavy at times. Areas from Georgian Bay through Eastern Ontario will see this wintery mix arrive Thursday night, thus the watch has been extended to include these regions.
Poor travel conditions are expected over the duration of this event. In particular, the Thursday morning commute may be challenging with icy conditions on untreated roads for areas from the Greater Toronto area westwards to Lake Huron. And it may be even more problematic for the evening rush hour. Of greater concern is the risk of widepsread power outages due to downed tree limbs and power lines due to 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 an appreciable swath of Southern Ontario. Mixed precipitation is expected to persist into Friday (especially for Eastern Ontario) followed by a gradual improvement.
There is still some uncertainty as to the track of the storm and the extent of the cold air Thursday. This will have an impact on whether the regions in the winter storm watch receive predominantly ice pellets or freezing rain. Environment Canada will monitor this situation closely and will issue warnings as needed as the evolution of the storm becomes more certain.
