An ice storm is possible mid-week for part of southwestern Ontario, according to Environment Canada.

A “prolonged freezing rain event” could lead to significant ice build up in some areas starting late Wednesday into Thursday.

As of Monday afternoon, an approaching Colorado low is expected to bring the potential for a prolonged freezing rain event across portions of southwestern Ontario between Sarnia and Niagara.

Environment Canada says there remains some uncertainty to exact location and timing of the freezing rain axis, as well as the amount of ice accretion that may occur.

Precipitation may begin as snow or ice pellets before changing to freezing rain at the onset late Wednesday.

Freezing rain warnings are expected to be issued as the event draws nearer.

Monday: A mix of sun and cloud. Temperature steady near plus 3
