A Colorado Low is Barreling In— Rain, Snow, and a Wild Monday in Quetico Country
Forecast for Sunday, April 13, 2025
Atikokan, nestled at the edge of Quetico Park, is in for a rollercoaster of spring weather this week—and today is the calm before one very snowy storm. As of 6:00 AM EDT, the temperature sits at -2.5°C with a light northeast breeze at just 3 km/h, giving a slight wind chill of -4°C. Humidity is sitting high at 96%, and the barometric pressure has begun to drop, currently at 100.9 kPa, which is the meteorological equivalent of “something’s brewing.”
Today starts off quietly with a mix of sun and cloud, and those early fog patches will slowly lift. But don’t be fooled by the mild high of 13°C expected later this afternoon. Clouds will begin to roll in around noon, followed by a 60% chance of showers late this afternoon. The UV index is a moderate 3—safe enough for a stroll through the woods, but pack the rain gear if you’re planning to be out past lunch.
Tonight: Rain Begins—Then a Major Snow Shift
Sunday night will mark the beginning of a dramatic weather transition. Cloudy skies will continue, and there’s a 60% chance of rain showers this evening before a more organized rainfall begins near midnight. Total rainfall could hit 10 to 20 mm, and with temperatures hovering around 1°C overnight, there’s concern about freezing rain during the transition phase. Winds will shift from the north at 20 km/h after midnight, setting the stage for a snow-packed Monday.
Monday, April 14: Heavy Snowfall Warning Likely
Here’s where things take a serious turn. A Colorado low will sweep into the region Monday morning, turning overnight rain into heavy snow, potentially dropping between 15 to 25 cm by the end of the day. This system also brings a risk of freezing rain during the changeover, which could make travel hazardous. Expect strong northwest winds at 30 km/h, gusting to 50, and reduced visibility in blowing snow. Temperatures will hover around zero all day, and the UV index will sit at a low 1—not that anyone will be basking in the sun.
Monday night remains cloudy with a 40% chance of flurries, brisk winds, and a low of -5°C. If you don’t have your shovel handy yet… it’s time.
Midweek: A Gradual Return to Sanity
Tuesday, April 15, stays chilly and mostly cloudy with a 30% chance of light flurries and a high of just +4°C. But things start to turn around by nightfall with clearing skies and a sharply cold low of -11°C—brace for crunchy footsteps in the morning.
By Wednesday, it’s back to classic spring vibes with sunny skies and a high of +7°C. Clouds return by night with a 30% chance of rain showers or flurries, and the overnight low settles at -2°C.
What to Wear in Atikokan This Week
Today’s mild spell might tempt you into lighter clothes, but don’t be fooled. You’ll need waterproof outerwear by this evening, and by Monday, it’s full-on snowstorm attire—insulated boots, thick layers, and that trusty snowbrush. Tuesday and Wednesday still call for winter gear, especially in the mornings.
Atikokan Weather Trivia
Did you know? Atikokan is often dubbed “Canada’s Canoeing Capital,” but it’s also one of the few towns in Ontario where April snowstorms are just another day in paradise. In fact, the region has seen April dumps of over 30 cm before—so this week’s storm may not be breaking records, but it’s certainly in good company.
