Frigid Morning, Sunny Skies, and a Slow Warm-Up

Sioux Lookout starts the day at -21°C with a wind chill of -26°C. A slow warm-up begins midweek, with highs reaching 13°C by Friday. A mix of rain and snow ahead

Sioux Lookout is starting the day with a bone-chilling -21.2°C under clear skies. With humidity at 82% and a light northwest wind at 6 km/h, the wind chill is making it feel even colder at -26°C.

The pressure is at 101.5 kPa and rising, indicating stable weather ahead. Visibility is excellent at 24 km, but with temperatures this cold, the real concern is frostbite—exposed skin can freeze in minutes.

As the day unfolds, expect mainly sunny skies with winds picking up slightly to 15 km/h. The high will reach -10°C, but the wind chill will linger at -28°C this morning before improving to a slightly less harsh -15°C in the afternoon.

The UV index remains low at 2, so while sunglasses might be helpful against the bright snow, sunscreen won’t be a top priority.

Tonight, clear skies will give way to some partial cloud cover after midnight. Winds will remain light at 15 km/h, with temperatures dropping to -18°C. Wind chills will hover around -16°C in the evening and -22°C overnight, making for another brutally cold night.

Midweek: A Shift Toward Milder Weather

Wednesday brings increasing cloudiness with a 40% chance of flurries. Winds stay light at up to 15 km/h, and for the first time in a while, the temperature will climb above freezing, with a high of +1°C.

However, the morning will still be frigid, with a wind chill of -22°C before things improve in the afternoon. The UV index remains at 2.

Wednesday night will clear up again, with a low of -11°C.

By Thursday, things continue warming up, with cloudy skies and a 30% chance of either flurries or rain showers. The high will reach +2°C, and the night will remain relatively mild, with a low near 0°C and a continued slight chance of precipitation.

Looking Ahead: A Dramatic Spring Surge

Friday is shaping up to be a major turnaround, with cloudy skies and a 60% chance of flurries or rain showers.

The high will soar to 13°C, which will feel downright tropical compared to today! However, the night brings a mix of snow or freezing rain, with temperatures staying above freezing at +3°C.

What to Wear?

Today and tonight demand serious winter gear. A heavy parka, insulated gloves, a hat, and a scarf are essential to protect against the frostbite-inducing cold.

By Wednesday, layers will still be necessary in the morning, but a lighter jacket may work by the afternoon.

By Friday, you might even be able to ditch the winter coat for a rain jacket instead!
