Winnipeg Braces for Sudden Summer Heat, Says Meteorologist Colleen Bready

Winnipeg has been enjoying a rare, lingering cool‑down after that early‑season cold snap, but the calm is about to be broken. Meteorologist Colleen Bready says a warm front is barreling in, and within a matter of hours the city could feel a dramatic jump to genuine summer heat.

“I’m looking at the models and they’re all pointing to a quick‑moving ridge of warm air that’s going to push temperatures up to the low‑30s Celsius by Thursday afternoon,” Bready explained on the morning broadcast. “That’s a big swing from the 15‑20 °C we’ve been seeing over the past few days.”

What’s more, the humidity isn’t going to stay low. As the warm air mass meets a lingering moisture plume from the southern United States, the heat index could creep into the high‑30s, making it feel noticeably hotter than the thermometer actually reads. In plain English: it’ll be the kind of sticky, “just stepped out of a warm blanket” feeling many of us haven’t experienced yet this year.

Given those numbers, Bready says a heat advisory is very likely to be issued later in the week. “When you’re looking at a heat index above 35 °C, that’s when we start telling people to take precautions,” she noted. “Stay hydrated, limit outdoor activity during the peak heat of the day, and keep an eye on kids, seniors, and anyone with health conditions that could be aggravated by the heat.”

She also offered some down‑to‑earth tips for keeping cool: drink plenty of water (or an electrolyte‑rich beverage if you’re sweating a lot), wear light‑coloured clothing, keep curtains drawn during the sun‑intense midday hours, and use fans or air‑conditioning whenever possible. “Even a simple trick like placing a bowl of ice in front of a fan can create a makeshift breeze that feels a lot more refreshing,” Bready suggested with a chuckle.

There’s a silver lining, though. The forecast shows a chance of thunderstorms late Friday night and into Saturday, which could bring a brief reprieve and some much‑needed rain. “Those storms will help knock down the humidity a little, but they won’t cool things down dramatically,” Bready added. “It’s just a short break before the heat settles back in for the weekend.”

In short, Winnipeg residents should prepare for a quick transition from a mild spell to a genuine summer heat wave. Keep your water bottles handy, plan indoor activities for the hottest part of the day, and don’t forget to check in on neighbours who might need a little extra help staying safe.
