Morning Fog, Afternoon Heat – Wildfire Haze Lingers Across the Region
Sunday, June 15 – A Warm and Hazy Father’s Day Forecast
Sioux Lookout wakes up to cloudy skies and 100% humidity, making for a heavy, damp start to the day. As of 6:00 AM CDT, the temperature is a mild 9.6°C, and there’s barely a breeze with winds from the SSE at 7 km/h. Atmospheric pressure is rising at 102.3 kPa, which hints at some clearing ahead. Visibility remains decent at 24 km, though hazy conditions are expected through the morning due to wildfire smoke lingering across the region.
That haze will gradually lift as the day warms up, and sunshine will break through, giving way to a mix of sun and cloud this afternoon. Winds will pick up out of the south at 20 km/h, helping push the mercury up to a high of 24°C, with a humidex of 27 making it feel slightly warmer and more muggy. The UV index climbs to 8, rated very high, so slather on that sunscreen — even if skies look filtered through smoke.
Tonight – Calm Evening, Showers Possible Overnight
Expect partly cloudy skies this evening, with a 30% chance of showers overnight. Winds will lighten after sunset, and the temperature will ease down to a low of 12°C. Though the rain chances are slim, it’s still a good night to keep your umbrella parked by the door, just in case.
Monday, June 16 – Humidity Builds with Storms Brewing
Monday brings another round of sun and cloud, with early morning and late afternoon showers possible. There’s a 30% chance of showers early on, ramping up to 60% by late afternoon, and a risk of thunderstorms rolling in with that unstable air mass.
Temperatures will peak at 25°C, but with the humidex hitting 28, it’ll feel downright tropical. Winds shift throughout the day, and the UV index remains very high at 8, so protection from both the sun and the storm is your best plan.
Monday night will stay cloudy, with a 40% chance of showers, and a low of 14°C.
Tuesday, June 17 – More Clouds, More Moisture
Tuesday continues with cloudy skies and a 30% chance of lingering showers. Temperatures moderate slightly with a high of 22°C, followed by a relatively warm night at 13°C with cloudy periods overhead.
What to Wear
Layers are your friend today — start with a light jacket or hoodie for the damp morning, and switch to breathable clothing as the sun and humidex ramp up. A wide-brim hat, sunglasses, and high-SPF sunscreen are must-haves. And don’t forget to stay hydrated, especially if you’re spending time outdoors under the hazy sun.
Weather Trivia – Why the Haze Lingers
Ever wonder why wildfire haze seems to stick around even when skies are clear? The answer lies in temperature inversions — a layer of warm air aloft traps smoke and pollutants near the surface, reducing air quality and limiting visibility. It’s nature’s not-so-friendly version of a smoke-filled snow globe.
