If you're planning on spending the last long weekend of the summer outdoors, you may want to bring an umbrella. That's from Environment Canada's Natalie Hassel, who says she wishes she had some better news heading into the Labour Day long weekend. She says while tomorrow will see decent temperatures during the day with a mix of sun and cloud, that will change as we move further into the weekend.

"A low-pressure system we currently see forming right now over Alberta and Montana will make it to southern Manitoba by Sunday morning. The forecast calls for periods of rain, and a high of 22. That really continues into Monday, where right now the forecast is for 60 per cent chance of showers."

She notes the low-pressure system could also bring scattered thunderstorms into the region. While Hassel notes the summer has seen many severe weather events taking place, the severe thunderstorm season tends to slow down in September. However, she says that doesn't mean you should throw caution to the wind in the event of a storm.

"All you need is a lightning strike, and things can go very differently in terms of how your day was going. Whether we have severe elements in the thunderstorms we're likely to see this weekend and into early next week, I would still take the same precautions."

Hassel says it seems typical for the weather to feature at least some precipitation during a long weekend, describing it as a southern Manitoba trend. While the weekend will see rain, she says we're going to experience some gorgeous weather heading into the long weekend. She says while temperatures have started to cool down in the past few weeks, those in the region will actually need to take precautions to prevent overexposure to the heat.

"We're looking at rather warm temperatures forecast for Friday in Portage. It's a high of 26, but a humidex of 30. It's not hot at all, compared to what we've seen earlier in the season but it is hot compared to what we've seen in the last couple of days."

Environment Canada currently predicts we could see an end to the rain as late as next Wednesday.
