Monday will bring heavy rain at times to the Golden Horseshoe, with some showers in Southwestern Ontario and the GTA. Clouds will decrease through the day, leading to mainly sunny skies to sun mixing with clouds elsewhere.
Rain and thunderstorms in the Golden Horseshoe and Niagara Region are likely to produce torrential downpours and will be slow moving at times, and may become stationary. This is expected to lead to localized flooding. The exact locations impacted remain uncertain at this time. Excessive rainfall amounts may be possible.
The upcoming week is expected to bring a slight chance of showers mid-week with temperatures mainly remaining in the 20s.
