Off-and-on showers are the order the day for today and much of the week.
Environment Canada says that skies this morning will turn to a mix of sun and cloud, with a 60 per cent chance of showers and the risk of a thunderstorm. The high this afternoon will hit 25ºC, and partly cloudy skies will persist into this evening, with the continuing chance of showers and possible storms.
Overnight, temperatures will drop to about 10ºC, before tomorrow — the high point of the week, with mainly sunny skies and a high of 28ºC.
Temperatures will be a shade lower on Wednesday, with a high of 27ºC and a chance of showers.
But things really start to slide after that. Thursday will likely see showers, with a high of just 23ºC, followed by cloudy skies on Friday and a high of 19ºC.
The weekend will be cool — verging on cold — with a good chance of showers on Saturday and a high of 17ºC, then a mix of sun and cloud on Sunday and a high of 18ºC.
The normal high for this time of year is 25ºC; the normal low is 11ºC.
The hottest it's ever been on am Aug. 18 was in 1945, when it was 36.1ºC. The coldest ever was in 1967, when it dipped to 1.7ºC.
