Environment Canada has issued a special weather statement for the City of Toronto, predicting significant rain into the Easter long weekend, but clearing up by Sunday.
The statement, issued just before 3:30 on Thursday afternoon, predicts rain between 25 and 55 millimetres on Good Friday and Saturday.
The rain may begin as early as Thursday evening, which has a 60 per cent chance of showers and risk of a thunderstorm.
The expected downpour is the result of a series of low-pressure systems from the Southern Great Plains states affecting Southern Ontario.
The statement warned that, due to the recent spring thaw, the ground still cannot absorb water as well as it can at other times. This might result in ponds forming or in flooding in low-lying areas.
Although wet, the long weekend will be relatively warm, with highs of 10 C on Friday and Saturday and 16 C on Sunday.
Environment Canada stated that the rainfall warning criterion of 50 millimetres of rain within 24 hours will not likely be met. The rain is expected to clear up by Sunday morning, which will be partly cloudy.
