Light Snow Today, Arctic Nights Through the Weekend
Winter Sticking Around with Snowfall and Deep Freeze
SIOUX LOOKOUT – WEATHER – While southern Ontario is dodging freezing rain and slippery streets, Sioux Lookout is staying true to its northern roots with steady snowfall, sub-zero highs, and overnight wind chills that could make a polar bear second-guess its life choices.
As of 6:00 AM CDT at Sioux Lookout Airport, it’s lightly snowing with a chilly -7.0°C reading on the thermometer. Humidity is high at 91%, and light winds from the east-northeast at 10 km/h make it feel closer to -12°C. Visibility is down to 5 km in the snow, and the barometric pressure is falling at 101.9 kPa, suggesting more action from the skies is on its way.

Friday Forecast: Snowy and Cold, with Gusty Winds
Today will remain snowy with a local accumulation of about 5 cm expected. Winds from the east will pick up to 20 km/h, gusting to 40, which means some blowing snow is possible—though not quite blizzard territory. Temperatures will top out at -3°C, but wind chills will make it feel more like -15°C this morning and -9°C this afternoon. The UV index is low at just 1, so your biggest concern today is snowflakes on your eyelashes—not sunburn.
Tonight: Light Snow Continues, Temperatures Drop
Overnight, periods of light snow will continue as the temperature slides to a low of -11°C. Winds will persist from the east at 20 km/h, gusting to 40, keeping the wind chill hovering around -18°C by the wee hours. If you’re heading out late or up early Saturday, bundle up tight—this kind of chill isn’t for the faint of fleece.
Saturday: A Touch of Sunshine and Another Cold Start
Saturday finally breaks the cloud cover with a mix of sun and cloud clearing by midday. Winds will start off from the northeast at 20 km/h before becoming light, offering a slight reprieve. The high will nudge up to -1°C, but it’s a frosty start to the day with a wind chill near -19°C in the morning, improving to around -5°C by afternoon.
Saturday night sees increasing cloudiness again with a low of -11°C—so no surprise snowball fights, but still cold enough to freeze your car’s soul.
Sunday and Monday: More Cold, Less Snow
Sunday stays cloudy with a high of -2°C. While the snow may pause, the cold isn’t going anywhere. Sunday night brings a low of -16°C under clear skies. Monday brightens things up with full sun, but don’t let the rays fool you—highs stay at -6°C with an even colder night on tap at -20°C.
What to Wear: Channel Your Inner Snow Warrior

Historic Weather Snapshot
Sioux Lookout’s warmest March 28 was a pleasant 9.9°C in 1986, while the coldest dropped to a bone-rattling -30.4°C in 1972. Today’s chill isn’t historic, but with wind chills dipping below -15°C and another cold snap coming Monday night, it’s more than enough to remind you that winter in the northwest doesn’t give up without a fight.
Weather Trivia: Northern Ontario’s Snowy Superpower
