Environment Canada says to expect a snowy Monday night around Ottawa-Gatineau, most of all under a snowfall warning for the Deep River area.
Advisories about the snow otherwise cover western Quebec and northern eastern Ontario, including Cornwall, Ottawa, Pembroke and Perth.
The snow is generally expected to start Monday evening and end late Tuesday morning or early Tuesday afternoon. It should begin earlier and snow harder to the west.
For example, Deep River’s snowfall warning calls for 15 to 25 centimetres of snow. Ottawa’s winter weather travel advisory puts the range at five to 15 centimetres and the Cornwall area could max out at 10 centimetres.
All could have some blowing snow.
Western Quebec’s advisory predicts 10 to 15 centimetres of snow and does not focus on wind.
There are no alerts further south for communities such as Brockville or Kingston.
Colder temperatures are also forecast Monday night and Tuesday: an overnight low of –10 C in Petawawa and daytime high around –3 C Tuesday there and in Ottawa.
The average daytime high this time of year is 9 C.
