A Mix of Mild Temps and Moist Surprises — Classic Northwestern Ontario Spring
Today’s Forecast: Light Layers by Day, Parkas by Night
Sioux Lookout & Pickle Lake, ON — April 11, 2025 – A chilly but mostly manageable morning in Sioux Lookout and Pickle Lake, where temperatures at 5:00 AM CDT are hovering around -3.8°C, with a wind chill making it feel more like -5°C. Fog patches and cloudy skies are dominating the early hours, with a slight risk of freezing drizzle adding a slippery edge to those morning commutes or coffee runs. Visibility is solid at 24 km, but caution is advised until the fog lifts.
The humidity is sitting high at 88%, and winds are barely stirring from the north at just 2 km/h — practically still air, which only helps the fog and drizzle linger. Barometric pressure is at 102.4 kPa and rising, signaling a short-lived improvement in weather as the day rolls on.
The fog and drizzle are expected to dissipate near noon, giving way to clearing skies and a spring-like high of 11°C. The UV index rises to a moderate 5, so if you do spot the sun, it might be stronger than you expect. Winds will remain light today, with speeds up to 15 km/h, providing just enough breeze to remind you it’s still early spring in the north.
Tonight, we start with partly cloudy skies, but things turn cloudy again around midnight, with a 30% chance of showers before dawn. Winds will shift and pick up from the south at 20 km/h, and temperatures will remain relatively mild with a low of +1°C.
Saturday morning brings more cloud and a 60% chance of showers, but expect clearing skies in the afternoon as the system moves through. Temperatures rise to a pleasant 13°C, with winds easing off again later in the day. Saturday night, temperatures take a turn back to the cold side, with a low of -4°C under cloudy periods.
Sunday offers a mix of sun and cloud and a 30% chance of showers, with a mild high of 12°C. But don’t get too cozy — by Sunday night, there’s a 60% chance of rain or snow, followed by a mix of rain and snow on Monday, with a high of just 0°C. Monday night dips hard to -12°C, so the parka and mittens may need to come out of retirement yet again.
Clothing tips? You’ll want layers today — warm enough for the -4°C start, but easy to peel back when the sun shows up. Waterproof footwear and a rain shell wouldn’t go amiss with the threat of showers tonight and Saturday morning.
Fun fact for the weather-curious: Sioux Lookout and Pickle Lake sit in the heart of Ontario’s boreal shield, a region known for extreme weather swings and a mix of continental and subarctic influences. That’s why it’s not unusual to see 13°C and sunshine one day — and snow the next. Welcome to the rollercoaster!
On this date in history, Sioux Lookout has seen extremes of 18.6°C for a record high and -17.2°C for a record low. So today’s temperatures are a cozy middle ground by local standards.
