A Cool Day in April’s Hands, But Brighter Skies Are Around the Corner
Current Conditions and Today’s Forecast
Good morning from Thunder Bay, where the thermometer is keeping things brisk and the skies are mostly cloudy. As of 5:00 AM EDT, the temperature hovers around -4.8°C, but thanks to a light westerly wind at 4 km/h, it feels more like -7°C out there. Humidity is sitting at a relatively moist 71%, and visibility remains good at 24 kilometres. The barometric pressure stands at 101.8 kPa and is on the decline, hinting that a weather shift could be coming soon.
The forecast for today is holding steady with mainly cloudy skies throughout the day. Winds will remain light, gusting up to 15 km/h. The high will only reach a modest +2°C, and those stepping out early will be greeted by a morning wind chill of -11°C—definitely a “coffee and gloves” kind of start. The UV index will reach 3, so if you do manage to find a patch of sun, some light protection wouldn’t hurt.
Tonight and the Coming Days
Tonight will bring partly cloudy skies, with winds continuing up to 15 km/h and temperatures dipping down to -7°C. That will come with another bite of wind chill, making it feel like -11°C overnight.
Thursday is shaping up to be a sunnier affair. Mainly sunny skies will brighten the region, although morning temperatures will feel frosty at first with a wind chill of -12°C. Things improve through the day with a high of +5°C, and a moderate UV index of 4 will make sunglasses your most stylish functional accessory.
Thursday night brings cloudy periods and a low of -5°C, and Friday continues our slow and steady climb into spring. Expect a mix of sun and cloud with a high of 9°C, followed by cloudy periods and a low of -3°C that evening.
The weekend looks promising with Saturday bringing a mix of sun and cloud and a high of 11°C. On Sunday, clouds thicken and bring a 30% chance of showers, keeping the high at a pleasant 11°C. Overnight, that rain chance increases slightly to 40%, with a mild low of +4°C.
Historical Weather Notes
On this date in Thunder Bay, the historical high reached 19.4°C in 1981—an early burst of spring that locals still talk about. The record low for April 9th, however, was a biting -21.1°C in 1966. So today’s weather? Somewhere in the calm middle of the temperature timeline.
What to Wear
It’s still too soon to ditch the winter gear. Start your day with a warm coat, gloves, and maybe even a scarf. By the afternoon, a lighter jacket might do, especially if you’re moving around. But don’t be fooled by a +2°C high—there’s still enough chill in the air to catch you off guard.
