Innisfail, Alberta is starting the week with a chance of thunderstorms before conditions clear and temperatures climb well above normal, according to Environment Canada.

Monday afternoon brings a mix of sun and cloud with a 60 percent chance of showers and a risk of a thunderstorm, with a high of 23°C and a humidex of 25. The UV index is expected to reach 5, which is moderate. Overnight, the chance of showers drops to 30 percent with a continued risk of thunderstorm, but conditions are expected to clear before morning as the low falls to 7°C.

The rest of the workweek looks much drier and sunnier. Tuesday, Wednesday and Friday are forecast to be mainly sunny with daytime highs of 26°C, while Thursday will see clearing skies and a high of 22°C. Saturday will see a mix of sun and cloud and a high of 27°C. Sunday brings increased cloud with a 60 percent chance of showers and a high of 22°C.

These temperatures are above the seasonal norm for late August in the Innisfail area, which is a daytime high of 22°C and an overnight low of 9°C. The warm spell continues what has been a hotter-than-normal summer for much of Alberta.
