Showers and Thunderstorms Rolling Through, Followed by Clear Skies and Summer Heat

Monday, June 16 – Thunderstorms Possible as Temperatures Climb

Winnipeg wakes up under mostly cloudy skies and a muggy 16°C early this Monday morning, as observed at Richardson International Airport. Humidity is high at 88%, with a dew point of 14°C, making the air feel quite damp. Winds from the south at 10 km/h add a gentle breeze to start the day, while visibility remains clear at 24 km. The barometric pressure is at 101.2 kPa and falling, signalling a shift in weather is on the way.

Through the morning, clouds will continue to increase, and the 70% chance of showers kicks in late this morning into the afternoon. There is also a risk of thunderstorms, so don’t be surprised if you hear a rumble or two around lunchtime. Despite the unsettled skies, the mercury will rise to a warm 26°C, with the humidex making it feel more like 29°C. The UV index is a respectable 6, meaning some rays will still break through — sunscreen remains a must between storms.

Winds will shift north at 20 km/h by the afternoon, helping push this passing weather system along.

Tonight – Showers Taper, Skies Begin to Clear

Showers may linger into the early evening with a 40% chance of precipitation and continued risk of thunderstorms, especially just after sunset. Winds from the north will ease off, becoming light overnight as skies begin to clear. Expect a mild low of 13°C.

Tuesday, June 17 – Sunshine and Seasonal Perfection

Tuesday is shaping up to be a textbook summer day. Expect sunny skies, light northwesterly winds at 20 km/h, and a lovely high of 25°C, with a humidex of 27°C. The UV index increases to 7, so shade and sun protection should remain part of your routine. Clear skies will stretch into the night with a cooler low of 12°C, perfect for sleeping with the windows open.

Wednesday, June 18 – Rain Chances Return

Midweek brings another wave of moisture, with cloudy skies and a 60% chance of showers throughout the day. Highs will reach around 23°C, and the showers could extend into the evening as well, with a continued 60% chance of nighttime rain and a low of 14°C.

What to Wear

You’ll need to dress in layers today — breathable clothes for the humidity, but have a light rain jacket or umbrella at hand for passing showers or thunderstorms. Tomorrow, break out the shades, short sleeves, and SPF as the city soaks up some sunshine. And with comfortable overnight lows, it’s the perfect time to air out the summer duvet.

Weather Trivia – Prairie Skies and Power

Did you know? Winnipeg is often referred to as the “Lightning Capital of Canada” during the summer months. The city sees an average of 27 thunderstorm days per year, thanks to the flat prairie landscape and warm, moist air masses that frequently collide overhead. Keep your eyes on the sky!
