Marathon & Schreiber Weather: Winter Storm Warning in Effect – Snow Incoming!

Brace for Heavy Snow and Blowing Conditions This Weekend

Winter is making a bold statement across Marathon and Schreiber as a Winter Storm Warning is now in effect. A powerful low-pressure system will bring 15 to 25 cm of snow, with even higher amounts possible in elevated areas.

Travel along Highway 17 will be impacted. Be prepared if you are travelling.

Alongside the snowfall, reduced visibility and tricky travel conditions are expected, particularly near the Lake Superior shoreline. If you have travel plans, be prepared for snow-covered roads and blowing snow, making for  hazardous driving conditions from Saturday night through Sunday evening.

Current Conditions (7:00 AM EST, Feb 1, 2025)

The temperature at Marathon Airport is an icy -26.1°C, with humidity at 81% and a barometric pressure of 103.3 kPa. With calm winds at the moment, it may not feel too blustery yet, but don’t be fooled—wind chills are at a frigid -31°C. Frostbite is a real concern, so layer up if you’re venturing outside.

Saturday’s Forecast: Snow Moving In

The day begins with a mix of sun and cloud, but the peaceful skies won’t last long. By noon, cloud cover will increase, and by late afternoon, a 60% chance of flurries will develop ahead of the storm system. Winds will be light, up to 15 km/h, but the wind chill this morning is a harsh -31°C, improving only slightly to -14°C by afternoon.

If you have any outdoor errands, get them done early before the storm arrives!

Tonight: The Main Event – Heavy Snow & Blowing Conditions

By this evening, the real storm kicks in with 10 to 15 cm of snow, combined with local blowing snow as southeast winds strengthen to 30 km/h, gusting up to 50 km/h. The low temperature will settle at -10°C, but with the wind chill, it will feel like -13°C in the evening and drop to -20°C overnight.

If you’re heading out, expect reduced visibility and tough driving conditions. Stay safe and take it slow!

Sunday, February 2: More Snow and Gusty Winds

Sunday will bring another 10 cm of snow, with local blowing snow continuing due to south winds of 30 km/h, gusting to 50 km/h. The good news? Temperatures will climb to -1°C. However, the morning will still feel bitter, with wind chills of -17°C, improving slightly to -8°C in the afternoon.

By Sunday night, the snow will taper off into cloudy periods with a 60% chance of flurries. Temperatures will fall to -14°C, keeping things frosty.

Monday, February 3: A Much-Needed Break

Monday looks calmer, with a mix of sun and cloud and just a 30% chance of flurries. The high will be -10°C, a significant drop from Sunday. Monday night will bring cloudy periods with a continued 30% chance of flurries, and temperatures plunging to -22°C.

Winter Wardrobe Advisory

With wind chills near -31°C this morning and -20°C overnight, full winter gear is a non-negotiable. That means thermal layers, insulated coats, gloves, hats, scarves, and proper winter boots. If you’re out shoveling, take breaks—this storm is delivering a lot of snow in a short time!

Fun Fact: Marathon’s Snowiest Winter

Did you know that the snowiest winter on record for Marathon was in 1989, when a staggering 470 cm of snow fell over the season? While this storm won’t bring us anywhere near that, it’s shaping up to be one of the more intense snowfalls this winter!

Stay warm, stay safe, and enjoy the snowstorm—preferably from indoors with a hot drink!
