A mix of sun and cloud will shape most of the day's weather, however Environment Canada is saying there is a 40 per cent chance of showers in the afternoon with that thunderstorm risk.
It says localized rainfall of up to 25 mm is possible in isolated thunderstorms around southern Ontario. None of the thunderstorms are expected to be severe, however.
Winds coming southwest will reach speeds of 40 km/h, gusting to 60 in the afternoon with a high 16 except 11 near the lake.
The rain is expected to end near midnight, and clearing after that.
Friday will be mainly sunny, with increasing cloudiness in the afternoon, then periods of rain and a high of 12.
The first part of the adage "April showers bring May flowers" certainly appears to be coming true, as precipitation is forecasted for five out of the next six days.
