Thunder Bay, ON – A winter weather system is set to impact northwestern Ontario Friday, bringing up to 15 cm of snow, strong winds, and hazardous travel conditions across the Thunder Bay region.
According to Environment Canada, the system will arrive early Friday morning, producing snow at times heavy, mixed with ice pellets and blowing snow. Local snowfall totals could reach 10 to 15 cm by late afternoon. Northerly winds gusting up to 50 km/h are expected to cause reduced visibility on roads and highways, particularly in open areas.
Wind chills will intensify the system’s impact, dipping to -10°C during the day Friday and falling to -9°C Friday night. The coldest stretch arrives Sunday night, with temperatures expected to drop to -14°C under clear skies. This marks a notable deviation from late March norms, with average lows typically near -7°C.
Motorists are urged to avoid non-essential travel during peak snowfall hours and to equip vehicles with winter tires. Residents should prepare for blowing snow, icy surfaces, and potential delays. Outdoor activities should be limited during periods of poor visibility and extreme cold.
Temperatures are expected to gradually recover by midweek, with sunny conditions forecast for Monday and Tuesday.
