September has arrived with cooler temperatures and showers, but the outlook for the last unofficial weekend of summer isn’t all that bad according to Environment Canada.
Increasing cloud Thursday and a high of just 21 C are harbingers of a low-pressure system expected to bring some showers overnight. Friday, there should be a 70 percent chance of showers and a risk of thunderstorms across the southern Interior with an overnight low dipping to 11 C in Kamloops.
After Friday’s itinerant conditions, the Labour Day long weekend promises variable conditions. Saturday’s forecast calls for a high of 19 C and a 30 percent chance of precipitation. Sunday may bring the best weather of the holiday weekend with a mix of sun and cloud and a high of 21 C. On Monday, there is a risk of showers again.
Once the weekend is over, the chance of showers gives way to a mix of sun and cloud into the week with highs of 21 C, slightly cooler than normal.
