However it won't be as wet as some feared. It's starting to look as though potential rainfall amounts will be on the low end of the predictions, with around 10 millimetres for Toronto on Tuesday and Christmas Eve, with the wider GTA getting between five and 15 millimetres.
Temperatures will be warm on Christmas Eve with highs across the GTA ranging from 8 to 10 degrees, but will ease back down to the low single digits for Christmas Day, with lingering showers possibly changing to a rain and snow mix.
"Not a white Christmas this year I'm afraid," said CBC meteorologist Jay Scotland. "Although to the north, lake-effect snow will fire up through the snow belt with a shift in winds."
As expected, winds will pose the biggest threat to holiday travel, ramping up late Wednesday evening through Christmas Day with gusts from 60 to 90 kilometres per hour possible. Gusts immediately along Lake Shore Boulevard could even exceed 90 kilometres per hour.
This could result in some travel delays and localized power outages due to downed branches and even some downed trees. But, important to note, potential outages should not be a repeat of last year's ice storm, as there is no freezing rain in the forecast.
