The first look at this week's action for the Pirelli World Challenge Series at Canadian Tire Motorsports Park says that clouds will be the dominating factor with some chances of rain mixed in.
Friday will be a mostly cloudy day and cool. I do believe the sun will peek out at some times during the day, but not enough to make a difference in warming the temperatures much. Highs will only reach the middle 60s. No chance of rain at this moment. Overnight lows will be in the lower 50s.
Saturday will be the wettest day of the weekend, I believe. Cloudy skies throughout the day with occasional showers possible. Highs should reach the upper 60s. Chance of rain as of now is at 50%. Overnight lows will once again fall to the lower 50s.
Sunday will be a day that will hopefully dry out by the afternoon. As of now, cloudy skies with a chance of showers during the morning hours. Showers should move out of the area by the late morning hours and the afternoon should be dry. Highs should reach the lower to middle 70s. Chance of rain as of now is 30% during the morning.
