Light Snow and a Wet Mix Welcome Monday in the Lakehead
THUNDER BAY – WEATHER – Thunder Bay is rolling into the new week with a little déjà vu — snowflakes in late April? Say it isn’t snow! Yet here we are, with Mother Nature tossing out one last (we hope) wintry curveball before spring really settles in.
Those big wet snow flakes are soaking so make sure you are dressed for that this morning.
Don’t pack away that snow brush just yet, because flurries and rain are both on today’s forecast menu.
Slush Alert: Snow and Rain Mix Through the Day
As of 7:00 AM EDT, light snow is falling at Thunder Bay Airport, and visibility is down to just 1.6 km — so watch those roads. The temperature is hovering just above freezing at 0.2°C, with a matching dew point and a saturated 100% humidity level.
Pressure is at 101.4 kPa and falling, which tells us the weather system responsible for this spring snow special is still developing.
Periods of snow or rain are expected throughout the day, with up to 5 cm of snow possible locally — enough to give your garden a frosty white coat and make that morning commute just a touch more adventurous. The northeast wind currently at 13 km/h will shift northwest by late morning, picking up to 20 km/h and gusting to 40. Today’s high reaches a chilly +3°C, and the UV index is low at 2 — not much sun to bask in.
Tonight, the snow or rain tapers off, giving way to clearing skies. Winds will ease off as well, becoming light after gusting through the evening. The low drops to -2°C with a wind chill making it feel like -5 overnight. Spring may technically be in the air, but it’s taking the scenic route.
Sun on the Horizon: A Brighter Tuesday Ahead
Tuesday offers a refreshing change — sunshine returns in the morning before clouds move in later in the day. Winds will be light, and the high climbs to a more tolerable 7°C. Be prepared for a brisk start, though, with a morning wind chill near -4.
Tuesday night brings more cloud cover and a 40% chance of rain showers or flurries, with the temperature staying just above freezing. Wednesday and Thursday continue the cool trend, staying cloudy with a chance of scattered flurries or showers and highs near 9°C.
Wardrobe Forecast
Winter meets spring in your closet today. Layer up with something waterproof and warm, especially if you’re out during snow or rain. Boots are still a good idea, and you’ll want gloves for that wind chill later on. The weather may not be fashion-forward, but you can be.
Thunder Bay Weather Trivia: Snow in April? Yep, It’s On Brand
If you’re wondering whether late-April snow is normal in Thunder Bay — the answer is a frosty yes. The city has seen record lows as chilly as -12.2°C on April 21 (set back in 1940), and the highest ever temperature for this day? A sun-soaked 26.7°C in 1987. With that kind of range, it’s no surprise the city’s spring comes with a little bit of everything.
