Very warm air will continue to deliver summer weather to Atlantic Canada for much of this week. In some areas of Atlantic Canada, the temperatures are about 10 degrees above seasonal. In Quebec, temperatures are a couple of degrees above normal for this time of year.
Ontario is a different story. Today there is a huge trough in the jet stream.
The jet stream separates warm air from cooler air. That trough in the jet stream will push further east this week and could bring some snow to northern Ontario toward the middle part of the week.
The southern Prairies will also be a touch colder while northern sections and British Columbia will see temperatures a few degrees above seasonal.
Looking at precipitation, it will likely be a wet week across Labrador, Quebec, and Ontario.
