Winter storm warning in effect.
A wintery combination of ice pellets and freezing rain on the way.
Periodic rain will affect the area tonight, but a more wintery change is on the way. Colder air will arrive later tonight and coincide with an approaching low currently over Missouri. Ice pellets mixed with some snow are expected to develop on Thursday in the warned regions and generally change to freezing rain later Thursday or Thursday night. It may very well fall heavy at times.
Poor travel conditions are expected over the duration of this event. In particular, the Thursday afternoon commute may be challenging with icy conditions on untreated roads. Of greater concern is the risk of widespread 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.
It should taper off by Friday morning with temperatures rising above freezing.
There is still some uncertainty as to the extent of the cold air. This will have an impact on how much falls as ice pellets versus freezing rain. Freezing rain will have a higher impact with power outages and slippery roads and sidewalks. But the expected 5 to 10 cm of ice pellets will also be problematic for travellers.
Global warming is so 2012.
