According to The Weather Network Summer Outlook, a seasonal to warm summer is expected across the country.

"Overall, above to near normal temperatures are expected across western Canada, with above normal in much of the east as well, but close to normal in central areas in between," says Chris Scott, Chief Meteorologist at The Weather Network. 

Forecasters say there will be a tendency for many regions to experience lengthy periods of warmer or cooler than average and/or dry or wet weather days in a row, especially during the first half of summer. 

This would be in contrast to the more usual change of dominant weather type every two or three days.

"Precipitation is always trickier to predict because much of the rain we get in the summer comes in the form of showers and thunderstorms, which are hit and miss and yet can give large rainfalls to skew the statistics in small local areas," adds Scott. "But we do think there may be a few areas of very active weather." 

There's a greater than average potential for severe local storms in the Alberta high plains east of the foothills. 

An active storm track is also possible from the central Great Lakes along most of the Laurentian highlands and into Labrador.

See below for provincial and regional breakdowns.

This outlook covers the period from June 2013 through August 2013.
