Mississippi Mills, Ontario is in for a warm and humid week with temperatures reaching 25 to 26 degrees Celsius and humidex values as high as 32 on Monday. Environment Canada is forecasting a mix of sun and cloud through the week, but residents should keep an umbrella handy because showers and thunderstorms are possible starting tonight and continuing into Wednesday.
According to Environment Canada, Monday will be mainly cloudy with a high of 25 and a humidex of 32. There is a 40 percent chance of showers this evening with a risk of thunderstorms, which could make roads wet and reduce visibility for anyone travelling.
Tuesday looks like the best day for outdoor plans. The forecast calls for a mix of sun and cloud with a high of 25 and a humidex of 29, a welcome break before the wetter weather arrives. Wednesday brings the highest chance of rain at 60 percent, with a 90 percent probability of thunderstorms in the morning, according to The Weather Network.
Along with the storm risk, the Mississippi River watershed is still recovering from 65 to 100 millimetres of rain that fell over the August long weekend, leaving water levels elevated and riverbanks slippery. The Mississippi Valley Conservation Authority issued a Water Safety Statement that was in effect through August 12, warning of high flows and unstable banks. Residents should use extra caution near moving water and keep children and pets away from fast-flowing areas.
This warm, sticky pattern is typical for late August in the Ottawa Valley, but the Government of Canada recently enhanced thunderstorm and tornado warnings to provide more precise alerts, helping communities stay safe during severe weather. If threatening weather approaches, take cover immediately and stay tuned to local alerts.
