Ste. Anne, Manitoba is in for a week of shifting weather, starting with thunderstorms and building toward a scorching weekend. Environment Canada is forecasting a risk of thunderstorms Monday afternoon before skies clear and temperatures climb, eventually peaking at 34°C by Saturday.

As of 10:00 AM Monday, the weather station in nearby Kleefeld recorded a temperature of 21.4°C with a humidity level of 77%, making it feel more like 27. The forecast calls for increasing clouds through the day, with a 60 percent chance of showers and a risk of thunderstorms this afternoon. Winds will shift from the west to the northwest, gusting up to 60 km/h. The high is expected to reach 26°C, but it will feel like 32 with the humidity. The UV index is at a moderate 3.

Once the stormy weather passes, a steady warm-up begins. Tuesday will be a bit cooler at 24°C, but the UV index will jump to a “very high” 8. That’s a level where sun protection is important–things like seeking shade, wearing protective clothes, and using sunscreen with SPF 30 or more. Temperatures will then rise day by day: 27°C on Wednesday, 30°C on both Thursday and Friday, then 34°C on Saturday under a mix of sun and cloud. Sunday will stay hot at 33°C. For context, the typical high for late July is 26°C, so we’ll be well above normal by week’s end.

Humidity will also be a factor. The humidex–a measure that combines temperature and humidity to show how hot it actually feels–will reach 32 on Monday, putting it in the 30 to 39 range that means “some discomfort” for people outdoors. Tuesday’s humidex dips to 27 before climbing back into the 30s later in the week as temperatures rise. Friday night brings a 60 percent chance of showers before the hot, sunny weekend sets in.

Anyone with outdoor plans should keep a close eye on the forecast, especially early in the week when thunderstorms could bring strong wind gusts. With extreme heat arriving by Saturday, it will be important to stay hydrated and limit time in the sun during peak hours. The UV index is expected to stay high for much of the week, so sun safety measures are a must.
