Thunder Risk This Morning, Heat Builds Into the Weekend Across Treaty #3 Communities
FORT FRANCES – WEATHER UPDATE – As the sun rises over Fort Frances, Couchiching, Mitaanjigamiing, Naicatchewenin, and Nigigoonsiminikaaning, today kicks off with warm, humid air and the lingering scent of rainfall. Temperatures hover around 15.8°C, with humidity at a muggy 94%.
Winds are gently nudging in from the northeast at 7 km/h, and the barometric pressure is on the rise at 101.2 kPa, suggesting an improving trend—at least for now.
Thursday Forecast: A Morning Rumble, Then Mostly Cloudy
Today begins with lingering showers, possibly ending early this morning, followed by mainly cloudy skies and a 40 percent chance of showers lingering into the afternoon. There’s also a risk of a morning thunderstorm, so don’t be too surprised if the sky offers a bit of drama before breakfast.
Temperatures are expected to climb to a high of 25°C, but with the added humidity, it’ll feel more like 29°C—a sticky, summer-like day in the making. The UV index is 7, so don’t skimp on sunscreen if you’re venturing out.
Tonight, skies will clear, offering a brief break in the pattern with just a few clouds and a comfortable low of 12°C—ideal for open windows and quiet evenings.
Looking Ahead: Friday Through Sunday – Heat Alert Lite
Friday will bring increasing cloudiness early in the day and a 30 percent chance of showers by afternoon, possibly joined by a thunderstorm. The thermometer climbs to 27°C, but expect it to feel more like 32°C with the humidex. That “just stepped out of a sauna” sensation will be familiar to anyone who’s survived an Ontario summer. The UV index jumps to 8, so shade will be your best friend.
Friday night grows cloudy with a 40 percent chance of showers, and overnight lows will be a warm 17°C.
Saturday turns up the summer heat with a mix of sun and cloud, a 30 percent chance of showers, and a high of 30°C. That heat may trigger pop-up storms, so don’t stray too far from shelter.
Saturday night and Sunday stay cloudy with a 60 percent chance of showers, and both days reach 30°C, so the air conditioners and fans will be working overtime. Overnight lows of 18°C will keep things tropically toasty.
Wardrobe Wisdom
Today: Light waterproof gear to manage the morning rain and possible thunderstorm, with a quick change into breathable summer wear as the day heats up.
Friday through Sunday: Think shorts, sun hats, and sunglasses, but keep an umbrella close and an indoor backup plan in case of passing storms. Hydration will be key—yes, iced tea counts.
