Summer Heat Peaks Today — Then the Bottom Drops Out

Friday: Pleasant Now, But Keep One Eye on the Sky

Wasaho Cree Nation is off to a warm and breezy start this Friday morning, with 18.1°C on the thermometer and partly cloudy skies reported from Fort Severn Airport at 8:00 AM. With 62% humidity and a dew point of 10.6°C, the air feels just right — neither sticky nor dry. A south-southwest wind at 13 km/h is starting to build, and visibility sits at a good 16 km.

The barometric pressure is 101.2 kPa and falling, suggesting that a weather system is on the move. Today will feature a mix of sun and cloud, with winds picking up to south 20 km/h gusting to 40 — enough to tousle the trees and send your ball cap flying. The high will reach 27°C, with a humidex of 30, and the UV index hits 7, which is high. You’ll definitely want sun protection if you’re out on the land or fishing the coastline.

Tonight: Calm Turns to Caution

The evening begins clear, but don’t be fooled — clouds roll in overnight with a 40% chance of showers and a risk of a thunderstorm before morning. Winds will stay active from the south at 20 km/h, gusting to 40, and the overnight low will be a warm 15°C.

This is one of those nights where it’s wise to batten down any loose gear around camp or property — gusts plus lightning could be on the way.

Saturday: The Storm Door Opens

Saturday sees a shift to mainly cloudy skies, with a 40% chance of showers and risk of a thunderstorm during the day. Temperatures remain summer-like with a high of 25°C and a humidex of 28, but the unsettled skies may limit time outdoors. The UV index drops slightly to 6, still in the high category.

Saturday night brings the more potent system with cloudy skies and a 60% chance of showers, and that’s when the cool air begins to flood in — overnight temperatures tumble to just 6°C.

Sunday Outlook: Hello Fall, Where Did Summer Go?

Sunday looks like an entirely different season. The temperature stalls at a chilly high of 10°C, with cloudy skies and a 30% chance of showers. Winds will shift and cooler northern air will dominate. Overnight, we drop to a brisk 5°C, with continued cloud cover — more October than June, to be honest.

What to Wear: Layers for the Mood Swings

Today: light summer wear, sunglasses, and water bottles. But keep a rain jacket close by for tonight’s possible thunderstorm. Saturday will still feel like summer but damp, so waterproof gear is smart. By Sunday, it’s full-on hoodie and long pants weather — the kind of turn that makes you double-check the furnace.

Wasaho Weather Trivia

Did you know? Wasaho Cree Nation is one of the few communities in Ontario that can experience both humidex highs near 30°C and wind chills below freezing — in the same week — during seasonal transitions. That northern Hudson Bay influence is no joke!

Also, Fort Severn has seen snow in June on record — though thankfully, not today.
