Guelph residents can expect a warm but unsettled week ahead, with temperatures above seasonal norms and multiple chances of showers and thunderstorms, according to Environment Canada. No weather alerts are currently in effect for the city.
As of 4:00 p.m. on Monday, September 14, conditions at the Guelph Turfgrass Institute showed a temperature of 18.6°C with winds from the north at 2 km/h. The normal high for this time of year is 20°C, but the forecast shows highs ranging from 23°C to 26°C through mid-week.
Tuesday brings a mix of sun and cloud with a 70 percent chance of showers and a risk of a thunderstorm late in the afternoon. The high will be 23°C with a humidex of 25, making it feel warmer. Wednesday is expected to be the warmest day of the week at 26°C, with a mix of sun and cloud and a clear night.
The unsettled pattern is linked to a stalled frontal boundary that is drawing humid air from the Mississippi Valley into southern Ontario. This “ring of fire” setup creates daily chances for rain and thunderstorms through mid-week, so residents should keep rain gear handy for outdoor plans.
Looking ahead to the weekend, temperatures will cool to around 19°C with cloudy skies and a 60 percent chance of showers Saturday night and Sunday. Environment Canada’s seven-day forecast shows no significant weather alerts at this time.
