We will hold onto the heat on Wednesday, but temperatures will start to fall later this week. Wednesday comes with a high of 24 C. The morning is expected to be mainly cloudy with a small chance of an isolated sprinkle between 7:30 and 11:30 a.m. The greater chance for rain is Wednesday night, where precipitation is expected to be heavy at times with the chance of embedded thunderstorms. Five millimetres of rain possible. By Thursday the city will cool to 22 C and by Saturday, it will be a chilly 14 C with gloomy conditions.
