The work week is getting off to a messy start.

A freezing rain warning is in effect for Toronto and much of Southern Ontario.

Snow, freezing rain, and ice pellets are all part of the mix for this morning. That will gradually change to rain. And then fog will develop this afternoon.

We’re expecting about two-to-four centimetres of total accumulation.
