Snow squalls are likely today.

Lake effect flurries off Lake Superior early this morning are expected to slowly intensify this morning ahead of an approaching trough. The activity should slowly shift southward this evening as winds become more northwesterly with the passage of the trough.

Local snowfall amounts up to 15 cm are possible. Travel along Highway 17 is expected to be hazardous.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Prepare for quickly changing and deteriorating travel conditions. Consider postponing non-essential travel until conditions improve.

Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
