Catching a Second Summer: Manitoba's Surprise Warm-Up After Just One Day of Fall

Well, isn't this a pleasant surprise? Just when we thought we'd officially settled into the crisp embrace of autumn, Mother Nature, with a little help from CTV News Winnipeg Weather specialist Colleen Bready, seems to have had a change of heart. According to her forecast from September 24, 2026, parts of southern Manitoba are gearing up for a delightful return to summer-like conditions this Thursday, practically scoffing at the mere single day of fall we’ve just had.

For those living in southern Manitoba, get ready to peel off a layer or two because temperatures are expected to climb comfortably into the mid-20s. That’s a truly welcome change, wouldn't you say? More specifically, folks in Winnipeg and the wider southeast region can anticipate a lovely stretch into the low 20s. Winnipeg itself is actually looking at a rather balmy 21 degrees Celsius. Now, just to put that into perspective, for late September, we'd normally be bundling up a bit more, with the seasonal high usually hovering around a cooler 16 C. So, this is quite the bonus warmth we’re getting!

Venturing eastward a bit, into Northwestern Ontario and the very southeastern corners of Manitoba, the forecast suggests that any lingering showers should kindly clear out by Thursday afternoon. However, it seems the summer spirit might not quite extend as far, as those areas are expected to feel a touch cooler, settling into a range of 13 C to 15 C. Still, no rain is always good news, right?

And what about our friends up north? Northern Manitoba, interestingly enough, has only a very slim chance of catching any Thursday afternoon showers. But here’s the kicker: it’s staying unseasonably warm up there too! While the absolute northernmost stretches might see temperatures in the comfortable mid-teens, areas a bit further south are actually looking at upper teens and even touching the low 20s. It seems the whole province is getting a slice of this unexpected warmth, albeit in varying degrees.

Beyond just the mercury rising, there are a few other little details to note. We're expecting to see the skies in parts of the southwest start to clear beautifully by Thursday afternoon. But do keep an eye out for potential fog – it could creep in and develop in various spots across Manitoba on Thursday night. For Winnipeg's upcoming days, it looks like a bit of a mixed bag, a proper rotation really. We're talking sunshine making a welcome return on Friday, followed by a somewhat soggy start to the weekend on Saturday. But don't despair! Sunday promises more sunshine, only for the rain to decide to pay another visit on Monday. It’s certainly keeping us on our toes, isn’t it?

So, there you have it – a delightful, albeit brief, encore performance from summer, gracing Manitoba just as fall was settling in. Time to soak up that sunshine while it lasts!
