Summer may be on its way out, but a warm, humid air mass associated with the season won't in such a hurry to leave southern Ontario, yet. Visit our Complete Guide to Fall 2026 for an in depth look at the Fall Forecast, tips to plan for it and much more! Expect cloudy periods with a few rounds of rain and thunderstorms next week as southern Ontario will be included in the ring of fire, with very hot and humid conditions situated over the Mississippi Valley. Be sure to stay alert to the changing conditions, and check for any weather warnings in your area. Sticky air mass as summer not ready to depart, yetA surface high establishes over the southern Mississippi Valley early next week. That means a hot and humid air mass will builds over the valley and the Southern Plains. As a result, the muggy and unsettled air mass will be transported into parts of southern Ontario. With the humid conditions in play, folks stuck with the muggy air mass in southern Ontario may see daily showers and/or thunderstorms through the second half of the work week, and potentially into next weekend.

Canadian families are heading to the apple farm. But before you make some core memories, here’s how the weather impacted the 2026 crop . "You’ll find this year, because of all the rain, there might not be as many apples on the tree, but they are larger. So they are a bigger apple this year, typically because of the rainfall," said John Hughes, farmer and co-founder of Springridge Farm. September is the month for the best picking! British Columbia, Quebec, Nova Scotia and New Brunswick are also in full force, sharing their crop with the rest of the country. (Tom Swinnen/Pexels)"The challenge we had with the apples this year was in the spring. We had a lot of frost damage with the flowers and buds. The crop this year is maybe 30 per cent less than last year. But the last two years have been very heavy, in Ontario anyways. I think it will be more of a normal year this year," said Hughes. Nearly all Canadian apple farms are family-owned (97 per cent). As you head out this season, know you are supporting generations' worth of family memories and farming.

Hawaii can’t catch a break this year. Three tropical systems brought destructive winds and flooding to the Pacific islands so far this year, marking a trio of unusual swipes in a state that usually goes years without any serious threats. Conditions placing Hawaii under constant threat this year are largely the same forces responsible for keeping the Atlantic basin historically quiet. Forecasters expect the Atlantic to remain silent over the next week even as Hawaii faces several additional threats in the days to come. DON'T MISS: Latest forecast calls for a historic El Niño to peak this winterA trio of storms cause damage, major floodingThree tropical systems have affected the Hawaiian Islands so far this season. Hurricane Lala struck the Big Island on Aug. 15, with the centre of the eye missing landfall by a few dozen kilometres. High winds and torrential rains caused widespread damage across the region. Some areas received more than 900 mm of rain from the storm. Just a week later, an additional 100 mm of rain washed over the Big Island as Tropical Storm Moke passed south of the archipelago.

Canada has officially recorded a temperature below -10°C for the first time this season. We’ve notched this milestone right around the point in the year when you’d expect to see the country’s first minus double-digit reading. CANADA’S FALL FORECAST: Exceptional El Niño favours extended fallAlert, Nunavut, dropped to -14.0°C on Friday, Sept. 11. Located on northern Ellesmere Island, Alert is the world’s northernmost permanently inhabited place. The station there hasn’t gotten this cold so early in the year since 2017. Communities throughout Nunavut are usually the first to reach this temperature milestone each year. The first minus-teens last year occurred on Sept. 8 in Isachsen, while the first such reading in 2024 arrived in Eureka on Sept. 18. This won’t be the region’s last cold intrusion, either, as additional bouts of cold air spill down from the North Pole. When can we expect that level of chilly air to begin dipping southward? This year may feature an extended wait as an unusually mild autumn is expected throughout much of the country. Content continues belowDuring a typical year, however, here’s how this winter-like chill typically progresses.

The remains are believed to be from a victim of the catastrophic Hurricane Helene flooding, which impacted Tennessee nearly two years ago. What factors caused Hurricane Helene to move so far inland?

While it may still be more than a week before summer officially comes to a close, the temperatures are set to take an unseasonable plunge on the Prairies in the coming days. Thankfully, we aren’t expecting any frost or flurries in the region quite yet, but daytime highs will barely crack the double digits in cities like Edmonton and Calgary, Alta., this weekend. It’s a good reminder that real winter weather, including dangerous cold, isn’t far off. With that in mind, we spoke to renowned Calgary HVAC expert, “Pete the Plumber,” about ensuring your furnace system runs smoothly all winter long. Saturday temperatures. (The Weather Network)Focus on the cooling before the warmingIf your home has an air conditioning system, Pete says it’s important to winterize that, as well. This can be as simple as cutting off its power supply, clearing debris and covering the top of the AC unit. Content continues belowCutting power helps ensure your AC system doesn’t start up during an unseasonably warm day (like during a chinook), which risks pulling water into the unit where it can freeze, expand and cause damage overnight.

"If clouds weigh so much, how do they float/stay in the sky? " — LeeAnnBefore I begin answering this question, the question itself may have already surprised you — clouds weigh a lot? Yes, an average cumulus cloud can weigh over 1 million pounds! To find out more on the science behind this, watch this video. Now back to the question, and it’s a great one. If clouds are so heavy, then why wouldn’t they fall out of the sky? Well, even though there’s an immense amount of water inside these clouds that contribute to their overall weight, the droplets themselves are extremely tiny. Get More of Our News on GoogleSet The Weather Company as a 'Preferred Source' to get quicker access to the news you value. Since they are so small, the rising air— that contributed to the cloud formation in the first place — keeps the tiny droplets suspended in the sky. It’s similar to thinking about dust particles floating around in your house — they stay suspended for much longer than you would think. Once the droplets collide and become bigger, and therefore heavier, we begin to see rain fall from the sky because gravity finally wins out.

The world just sweltered through a historic three-month stretch that saw record-breaking temperatures across nearly every continent and ocean basin. Temperatures will continue running warmer than normal as we dive into the autumn months, driven in part by a strengthening El Niño, virtually assuring that additional records are at risk in the weeks and months to come. DON’T MISS: Latest forecast calls for a historic El Niño to peak this winterThe list of records compiled by NOAA is voluminous. Average worldwide temperatures between June and August were the hottest ever observed during that three-month stretch of the year, running 1.21°C above normal. This was also the world’s hottest August on record, with average readings coming in 1.32°C above normal. Global records date back to 1850. Global sea surface temperatures reached an average of 21.18°C for four days in late August, which is the all-time warmest average ever observed. A strong and growing El Niño in the Pacific helped propel ocean temperatures to their lofty heights. North America notched its all-time warmest summer since records began in 1895.

A low pressure system moving out of South Dakota is set to bring active weather to northwestern Ontario late Friday and into Saturday. Thunderstorms are expected to develop Friday evening along a warm front, intensifying south of the border before crossing into northwestern Ontario.
