Thursday night freezing rain turning to snow on Christmas

Environment Canada is forecasting 10 to 20 mm of rainfall later Thursday with a risk of freezing rain. Then, Toronto will see 10 to 15 cm of snowfall by Friday mid-morning. It impossible to predict just what the roads will look like during the evening but conditions will be poor. The Accu Weather radar of the approaching rain and snow above was captured at 9.55 a.m. Thursday. Here’s what EC is saying.

Timing:
Rain will transition to snow by early this evening. Freezing rain may be possible during the transition.

Discussion:
Rain may become heavy at times today before changing to snow early this evening. A brief period of freezing rain may be possible this evening during the transition. By mid evening, all precipitation should be falling as snow, with as much as 10 to 15 cm of snow expected by Friday mid-morning.

Confidence is lower for if and how long freezing rain will occur for, but it is generally not expected to be a major impact for this event. Confidence is higher that a snowfall of 10 cm will happen tonight.

If 15 cm of snow is thought to be more likely, a Snowfall Warning may be issued. Stay tuned…regardless, expect poor road conditions beginning this evening due to accumulating snow.
