From Frigid Mornings to Blustery Afternoons – A Weather Rollercoaster!

Sioux Lookout starts frigid at -17°C but warms to 4°C before flurries and strong winds return tonight. Expect falling temperatures and blowing snow Friday

Sioux Lookout and Pickle Lake are waking up to a bitterly cold morning at -16.6°C, with mainly clear skies overhead. The humidity is at 87%, and a light north wind at 3 km/h brings the wind chill down to -19°C. The barometric pressure sits at 101.5 kPa but is falling, signalling an incoming change in conditions.

Today: Sun to Start, Flurries to Finish, and a Big Temperature Swing

It may be a frigid start, but temperatures will rise sharply to a high of 4°C by the afternoon. Expect sunshine in the morning, followed by increasing clouds and a 30% chance of flurries this afternoon. The wind will shift to the southwest at 30 km/h, gusting to 60 km/h late this morning, so it’ll be a blustery day. The morning wind chill of -24°C will make stepping outside feel extra brutal, so layer up! The UV index is 3, so some sun protection might be needed.

Tonight: Flurries, Blowing Snow, and Dropping Temperatures

Clouds will linger into the evening, bringing a 30% chance of flurries early on, followed by steady snowfall overnight. Expect 2 to 4 cm of snow, accompanied by blowing snow, which could reduce visibility. Winds will start from the southwest at 20 km/h, gusting to 40 km/h, then switch to the north at 20 km/h, gusting to 50 km/h near midnight. The temperature will drop to -8°C, with a wind chill of -10°C overnight.

Friday: Flurries, Falling Temperatures, and Icy Winds

Snow will taper off by morning, leaving behind a mix of sun and cloud with a 40% chance of lingering flurries. However, blowing snow could still be an issue early in the day. The temperature will plummet to -14°C by the afternoon, and with a north wind gusting to 50 km/h, the wind chill will make it feel like -22°C. The UV index remains low at 2, so it’ll be more about battling the wind than worrying about sun exposure.

Weekend Outlook: Some Sun, But the Cold Sticks Around

• Saturday will be mostly sunny, with a high of -4°C, followed by increasing clouds at night and a low of -13°C.
• Sunday turns cloudy again, with a 40% chance of flurries and a high of -1°C. The night will bring a 60% chance of snow and a low of -10°C.

What to Wear?

This morning, it’s all about bundling up—thermal layers, a thick winter coat, gloves, a hat, and a scarf will be essential against that -24°C wind chill. By the afternoon, when temperatures rise above freezing, you might be able to shed a layer. However, with strong winds and flurries overnight, tomorrow will feel much colder, so keep the heavy winter gear handy!
