Sioux Lookout Morning Snapshot
Thunder Bay – WEATHER DESk – Sioux Lookout is waking up under light snow and -8°C (technically -7.5°C) at 4:00 AM CST. The air is very moist for this time of year—93% humidity—which helps keep visibility reduced to about 5 km.
Barometric pressure is 101.1 kPa and falling, hinting at more unsettled weather nearby. Winds are light from the southwest at 6 km/h, making it feel like -11 with wind chill.
Today: Snow Ends Early, Then Flurries and a Wind-Driven Cooldown
Early this morning, periods of snow end, shifting to cloudy skies with a 40% chance of flurries. There’s also a risk of freezing drizzle early, so watch for slick spots that don’t look slick (the most annoying kind).
The bigger change is the wind: west 30 km/h gusting to 50 km/h. Temperatures fall to around -16°C this afternoon, and that wind will push the wind chill down near -24 later today.
Wardrobe call
Windproof outer layer, warm base layer, and insulated boots with good grip. Add a scarf/neck warmer and proper mitts—gusty winds plus falling temps can turn a quick errand into a face-freezing field study.
Tonight: Colder, With Flurries Still in the Picture
Tonight stays mainly cloudy with a 60% chance of flurries overnight. Winds ease earlier in the evening, but the cold settles in: low near -22°C, and wind chill drops to near -30 overnight. Frostbite risk returns for anyone lingering outdoors.
Christmas Eve and Christmas Day
Wednesday, Dec 24
Wednesday is cloudy with a 60% chance of morning flurries. High reaches -8°C, with wind chills around -23 in the morning and -13 in the afternoon.
Thursday, Dec 25

Looking Ahead: Friday Snow Continues

Travel note
This morning’s mix of low visibility and possible freezing drizzle can make roads tricky even before the wind kicks in. Later today, those 50 km/h gusts may create patchy blowing snow, especially on open stretches outside town—expect quick changes in visibility.
