Sticky with a chance of showers, thunderstorms but cooler weather in sight

[guest]

The autumnal heatwave is evaporating Wednesday – perhaps with the bang of thunder and lightning – and there’s some gorgeous autumn days in store.

Another 30 C September day is forecast for Wednesday but the clouds are expected to roll in, bringing a 60-per-cent chance of showers and the risk of a thunderstorm for the afternoon and early evening.

It’s expected to clear up overnight with a low of just 10 C.

Some rain would be welcome given that it’s been more than two weeks since most of us have felt a drop.

Twitter user Diane Sawchuk’s photo of sunrise Wednesday seems to have a hint of red. Sailor’s warning, anyone? The forecast definitely predicts cooler temperatures on the way.

For Thursday, expect a mix of sun and cloud and temperatures that might feel cool but are actually spot-on seasonal for the end of September: a high of 17 C and low of 5 C.

More of the same is on tap for Friday with a high of 15 C and low of 3 C.

Officially asked the #bearded #snowman for some winter weather. #winteriscoming hopefully. #ottweather pic.twitter.com/4RihZXFd1F

Sorry, snowman. Expect a gorgeous autumn weekend with sunshine and highs of 16 C Saturday and 20 C for Sunday, the first day of October.

The good weather holds through the beginning of the week with a mix of sun and cloud and highs of 19 C and 20 C forecast for Monday and Tuesday.
