Frosty Morning in Thunder Bay
Thunder Bay greets the day with partly cloudy skies and frigid temperatures. At 7:00 AM EST, it’s a bone-chilling -19°C, with a northwest wind at 13 km/h driving the wind chill down to a brisk -27. Humidity is sitting at 69%, and the barometric pressure is rising at 102.5 kPa, a sign of calmer but still cold conditions.

Tuesday’s Forecast: Cold but Clearing
Today, the skies will remain mostly cloudy through the morning, with a 30% chance of flurries lingering before clearing in the afternoon. Winds will increase slightly from the northwest at 20 km/h before becoming light later in the day. The high temperature will climb to -13°C, but it won’t feel that way—the wind chill will hover at a bitter -28 this morning and ease slightly to -19 this afternoon. Frostbite risks remain high, so limit your time outdoors and bundle up. The UV index is low at 1, so no sun protection is needed, but frost protection is crucial.

Light winds of up to 15 km/h will keep the wind chill hovering at -20 this evening and plunging to a frosty -30 overnight. With frostbite risks still present, tonight is best spent indoors by the warmth of a fireplace or heater.
Midweek Outlook: Snow Returns Wednesday
Wednesday starts off mainly sunny, but the reprieve won’t last long as clouds increase by late morning, leading to periods of light snow beginning in the afternoon. Expect around 2 cm of accumulation by the end of the day. Winds will shift to the southwest at 20 km/h, helping the high temperature reach -7°C. However, the morning wind chill will be a biting -32, improving to a more tolerable -12 by the afternoon.

What to Wear
Layering is the name of the game today. Start with thermal base layers, followed by a warm sweater or fleece, and top it off with an insulated parka. Insulated gloves, a toque, a scarf, and waterproof boots are essential to keep frostbite at bay, especially with wind chills reaching -28. If you’re heading out tonight, double-check your winter gear—exposed skin can freeze in minutes in these conditions.
