Brisk Morning with a Deep Chill
Sioux Lookout is starting the day off in true northern Ontario fashion—bitterly cold. As of 6:00 AM CST, the temperature sits at a frigid -19.9°C, with a light south wind at 5 km/h making it feel like -24°C. Humidity is relatively high at 85%, and the barometric pressure is at 101.5 kPa but falling, signalling some changes ahead. Visibility is excellent at 24 km, but don’t let that fool you—the cold is biting, and any exposed skin will feel it quickly.
This morning, a mix of sun and cloud dominates the sky, with a 30% chance of flurries lingering in the early hours. Winds will pick up significantly by early afternoon, shifting to the south at 30 km/h. Despite this, temperatures will rise dramatically, reaching a high of +2°C. However, it will feel brutally cold this morning with a wind chill of -25°C. The UV index remains low at 2, so while sunglasses might help with glare off the snow, sunscreen isn’t a concern today.
Snowy Night with a Chance of Freezing Drizzle
Tonight, snow will begin and continue until just after midnight, accumulating 2 to 4 cm before tapering off. Afterward, expect cloudy skies with a 60% chance of drizzle or flurries. As temperatures hover near +2°C, there’s a risk of icy conditions, especially on untreated roads and sidewalks. Winds from the south at 20 km/h, gusting to 40 km/h, will shift to the west near midnight, maintaining gusts of up to 40 km/h.
Looking Ahead: A Temperature Rollercoaster
Monday will bring continued cloud cover with a 40% chance of drizzle or flurries in the morning, transitioning to a 40% chance of just flurries later on. The west wind will strengthen to 30 km/h, gusting to 50 km/h, and temperatures will fall from +2°C in the morning to -1°C in the afternoon—so expect a slushy, slippery mix. The UV index remains at a low 1.
Monday night will remain cloudy with a 30% chance of flurries and a low of -9°C.
Tuesday keeps the cloudy trend going with a 30% chance of flurries and a high near 0°C. The night will bring a 60% chance of flurries and a low of -5°C.
Wednesday continues the pattern, with a 60% chance of flurries and a high of +1°C, followed by a cloudy night with a 30% chance of flurries and a low of -8°C.
What to Wear in Sioux Lookout
With temperatures fluctuating wildly from -20°C in the morning to +2°C later today, layering is your best friend. A heavy winter jacket, hat, gloves, and scarf are essential in the morning when wind chills make it feel like -25°C. However, by afternoon, things will feel much milder, so lighter, waterproof layers will be useful as snow and drizzle mix in. Waterproof boots are a must, as melting snow and slushy conditions will dominate the next couple of days.
Fun Weather Trivia
Did you know that Sioux Lookout has recorded temperatures as cold as -45.6°C? That was back in January 1943! While today isn’t quite that extreme, this morning’s chill is definitely a reminder that winter in Northwestern Ontario isn’t ready to quit just yet.
