Summer Heat Breezes In — But Rain Lurks Just Behind the Clouds

Thursday Starts Calm with Sunshine and a Hint of Heat

Wasaho Cree Nation is waking up to a mild 12°C under partly cloudy skies, as observed from Fort Severn Airport at 7:00 AM. The air is dry and comfortable with 73% humidity, and a dew point of 7.1°C. Winds are currently light from the southwest at 9 km/h, and visibility is solid at 16 km, offering wide views over the Hudson Bay lowlands.

The barometric pressure stands at 102.0 kPa and holding steady, pointing to a stable and pleasant weather day ahead. Expect sunny skies throughout the day, with winds picking up from the southwest at 20 km/h later this morning. Temperatures will rise to a high of 24°C, feeling more like 25°C with the humidex, and the UV index is 6, rated high — so even this far north, the sun will have some bite.

Tonight and Friday: Warm Winds and a Shower Signal

Tonight will start clear, then become partly cloudy overnight, as a system begins to approach from the west. Winds will lighten this evening, before shifting to south at 30 km/h near midnight. The overnight low will be 14°C, keeping things comfortably warm.

Friday brings a sunnier start, as skies clear in the morning, followed by a high of 27°C and a humidex of 31 — the warmest day of the week. Winds will remain southerly at 20 km/h, gusting to 40, so expect a warm breeze all day long. The UV index climbs to 7, so continue with sun protection. By Friday night, conditions shift again with cloudy periods and a 40% chance of showers. The overnight low holds steady at 14°C.

Weekend Outlook: Clouds Build and Temperatures Tumble

Saturday will bring a mix of sun and cloud, along with a 40% chance of showers and a high of 25°C — still warm, but less settled. Saturday night sees increased moisture with cloudy skies and a 60% chance of showers, and a sharp cool-down to a low of 7°C.

Sunday will feel much different — cloudy with a 30% chance of showers, and a much cooler high of just 12°C. The night remains cloudy with periods of clearing, and a low of 9°C.

What to Wear: Short Sleeves Today, Sweaters by Sunday

Today and Friday are pure summer — light, breathable clothing, sun hats, and sunscreen are your best choices. By Saturday night and into Sunday, you’ll want to reach for the raincoat and an extra sweater, as cooler air pushes in behind the rain. If you’re camping or on the land this weekend, pack for variety — it’s going to shift quickly.
