Weather report - Canadian Grand Prix.

Montreal's Circuit Gilles Villeneuve is surrounded by water, with the Olympic rowing basin on one side and the great St Lawrence Seaway on the other - but could it be in line for more from above this weekend?

Montreal, Canada

Friday
A lot of cloud across the region during the morning, with some early rain showers leaving damp surfaces. These should clear, to give a period of drier weather, before more showers bubble up in time for the afternoon. The precipitation could well be moderate to heavy, thundery at times too. Quite widespread showers in the area, later in the afternoon. Sunny intervals in between any rainfall. Temperatures will spike at 30C / 86F. Sixty per cent risk of precipitation.

Saturday
Once again, another day of sunshine and heavy, thundery showers. Perhaps fewer and further between, a little more scattered, compared to those on Friday, so a greater chance of drier weather with more sun and blue sky on offer. Mostly dry morning, showers arriving for the afternoon, threatening the qualifying session. Temperatures climbing to 31C / 89F. Forty per cent risk of precipitation.

Sunday
Rather cloudy today, with little in the way of bright, or sunny intervals. Perhaps some early dry weather, but not long before cloud and rain spreads from the west. A band of moderate to heavy precipitation, lasting for several hours around late morning, early afternoon. This band will turn showery later on, breaking up into thundery cells over the Montreal region. Continuing with the very warm conditions, top temperature of 28C / 82F. Sixty per cent risk of precipitation.
