Humid Heat and Thunder Threats Kick Off the Weekend in Northwestern Ontario
FORT FRANCES – WEATHER – A humid start to the day has settled over Fort Frances, Mine Centre, Red Gut First Nation, and Seine River. The temperature sits at 14.8°C, but the humidity is already a thick 93%, making the air feel quite soupy. Winds are out of the southeast at 11 km/h, with barometric pressure at 100.9 kPa and rising, hinting at more atmospheric change to come. No official observation on sky conditions, but the radar suggests a classic mix of cloud and sun—plus a dash of potential drama.
Today: Steamy Skies with Storm Possibilities
Expect a mix of sun and cloud today, but don’t get too comfortable—there’s a 30% chance of showers this morning and the risk of a thunderstorm to jolt you into weekend mode. The high soars to a sultry 27°C, but with the humidex at 32, it’ll feel much toastier than the thermometer suggests. The UV index sits at a very high 8, so slap on that sunscreen if you’re venturing out between downpours.
Wardrobe tip: It’s going to feel like you’re walking through a wet blanket, so stick to breathable fabrics. An umbrella wouldn’t be a bad idea—though in a thunderstorm, it might become a lightning rod, so stay safe and seek shelter instead!
Tonight: Building Clouds and Thunder After Dark
Clouds will roll in steadily this evening, with a 30% chance of showers early on escalating to a 70% chance of showers overnight, along with a risk of thunderstorms. Winds from the southeast will pick up to 20 km/h, gusting to 40, then taper off after midnight. The overnight low is a warm 16°C, ensuring a muggy night under the clouds.
Saturday: Stormy Start, Sunny End
Saturday may wake you with showers and the risk of a thunderstorm, but don’t let that fool you—clearing skies are expected by late morning, ushering in a scorcher of a day. Temperatures will rise to 28°C, but with the humidex peaking at 34, it’s going to feel downright tropical. That’s a great day for the beach—after the thunder clears, of course. The UV index hits 9, so it’s burn-baby-burn levels of sunshine once the clouds lift.
The night will offer a breather with cloudy periods and a 30% chance of showers. The low will be a mild 17°C.
Sunday and Monday: Cloudy, Then Clearing
Sunday stays warm and humid with a high of 29°C and a 30% chance of showers under mostly cloudy skies. Rain becomes more likely Sunday night, with temperatures dipping to 15°C.
Monday brings a welcome change with a mix of sun and cloud, a more manageable high of 22°C, and just a 30% chance of showers—perfect for starting the work week on a fresher, cooler note. Monday night will finally feel like summer bliss, with clear skies and a low of 11°C.
