Mother nature delivers some rather frightening weather for Halloween.

A slow-moving low pressure system over Southern Ontario will continue to track southeastwards this evening.

Rain has been falling much of the day across much of Southern Ontario. One exception has been regions northeast of Georgian Bay including Britt through Algonquin Park where a transition to wet snow has been occurring behind an Arctic cold front associated with the disturbance. This transition to snow will continue to migrate south tonight along and behind the cold front. The change over to snow will affect most areas south of Georgian Bay this evening reaching northern portions of the Greater Toronto area towards midnight.

Total snowfall amounts of 2 to 5 cm are likely south of Georgian Bay tonight, particularly over areas of higher elevation. It may even exceed 5 cm in some locales above the escarpment into the Dundalk Highlands. A few centimetres are also possible from areas near Kitchener to Caledon and eastward through York region. To the east of Georgian Bay, total amounts of near 10 cm will be possible by Saturday morning. However actual snowfall accumulation on the ground in some areas may be less due to melting on the still relatively warm ground.

The snow is expected to taper off early Saturday morning as the low system pulls away to the southeast.
