Special weather statement for Niagara

Environment Canada says significant mixed precipitation is threatening Tuesday.

A low pressure system brewing over the Southern Plains States may intensify into a winter storm as it tracks over Southern Ontario Tuesday. Snow and ice pellets are expected to arrive after midnight Monday, then will probably change through freezing rain to rain on Tuesday as milder air pays a brief visit.

Pecipitation will turn back to snow Tuesday night as colder air returns in the wake of the low pressure system.

How much snow, freezing rain, and rain falls on a particular region will depend on the exact track of the low and how far north the milder air can get into Southern Ontario.

This weather system may have a significant impact on travel.

Freezing rain warnings may be required as this event draws closer.
