The weather seems to be heading towards cooling off, with temperatures falling below the 20-degree mark after months of summer heat.

This week temperatures are supposed to be mostly below that, though the start of next week may see a bit more heat.

In general, this new fall climate is being seen as the end of summer.

Environment Canada meteorologist Sara Hoffman says that for her and her colleagues, the season's actually been started for a while.

"For meteorologists, fall started on September 1st, we're very strict on that. According to us, we're definitely right in the middle of fall and we're seeing some very seasonal temperatures in the area. Seasonal for this time of year is daytime highs of about 19 degrees Celsius, and a lot of our daytime high forecast temperatures are right around that mark."

Storms that are bringing rain to the southeast will also be changing with the temperature, as Hoffman explains that there'll be weaker storms compared to earlier in the year.

"The main difference is that we won't see those showers or storms get too strong. They won't be strong enough to likely develop into severe thunderstorms, but they will be strong enough to produce pockets of heavier precipitation.

"It's very similar in some respects and different in others. The main difference is it just won't be as severe or strong as in the summer."

As well, total rainfall amounts are expected to drop in the fall compared to the summer.

Hoffman describes the summer being the rainiest time of the year, with June leading those months, with around 74 millimeters over the month.

To compare, September brings around 31 millimeters, being a dryer month with that number falling lower and lower the closer to winter we get.
