Environment Canada issued a special weather statement Tuesday calling for freezing rain, ice pellets and snow across the London region later today.
An extended period of freezing rain is forecast for an area stretching from Sarnia to London and south to Chatham and St. Thomas.
Precipitation is expected to develop along a warm front that will reach Southwestern Ontario late this afternoon.
At first, it will start as rain, but as temperatures drop will change to freezing rain and ice pellets.
