    Canada expected to see typical fall with average to above normal temperatures and precipitation

    The Weather Network’s meteorologists have released this year’s Fall Outlook, forecasting the months of September, October and November. Most of Canada will experience typical fall weather as the country transitions from warm, summer conditions to colder, wet weather leading into winter. Similar to the summer, The Weather Network’s meteorologists expect most of the country will experience extended stretches of fair weather with normal to above normal temperatures followed by spells of cool and wet weather.

    “Cyclical weather patterns like we saw this summer are likely to continue into the fall for most parts of the country,” said Chris Scott, Chief Meteorologist at The Weather Network. “Fall is characterized as a transitional season where we typically see a wide range of temperatures, and the climate signals we’re seeing point toward a fairly typical transition this year. Most of Canada should enjoy warm, dry stretches in September, but on cue the weather will start to change quickly as we go into October and November.”

    End of Summer and Back to School

    Summer is finishing strong from the Prairies through Ontario and Quebec as warm weather is expected into the Labour Day weekend.  Most parts of the country should get at least two rain-free days out of three this long weekend, but thunderstorms will be a threat at times particularly from Manitoba across the Great Lakes into the St. Lawrence valley.  A low pressure system off the B.C. Coast will bring the chance of showers to coastal areas.

    Next week, fresher air will sweep across Ontario and Quebec as most kids head back to school, while the trend in Atlantic Canada is for wet, muggy weather.  The Prairies should see heat rebuilding as summer makes up for lost time.  In general, much of the country should average slightly above normal for temperatures over the first couple weeks of September.

    B.C.

    On the West Coast, areas like Vancouver and Prince Rupert can expect a typically wet end of October and November.  Temperatures should average near normal for most of B.C., but slightly above for Vancouver Island.

    The Prairies

    Most of the Prairie Provinces should expect near normal fall temperatures, with stretches of above normal temperatures more likely in September.  Precipitation will average near normal in most regions but slightly above near the Rockies.

     

    Ontario and Quebec

    In Ontario and Quebec, summer’s conditions means trees should be fairly healthy and should produce an opportunity to see a brilliant display of fall colours, peaking at the beginning of October in cottage country, and a couple weeks later farther south. Near normal temperatures and precipitation are expected in most parts of the provinces.

    Atlantic Canada

    This September marks the 10th anniversary of Hurricane Juan, which caused major damage in a swath through central Nova Scotia into PEI. Although the area hasn’t seen many storms this year, hurricane season normally reaches its peak in September and a higher than average number of storms across the Atlantic is predicted.
