Chilly morning.. building heat wave expected by late week
It was a chilly Tuesday morning over southern Manitoba with temperatures falling well into the single digits overnight. At Winnipeg airport, temperatures fell to 6C this morning, the coolest temperature of the month so far. Temperatures will warm up nicely today under sunny skies with afternoon highs around 25C. Another chilly night is in store tonight with lows near 10C, but then a significant warming trend is set to develop by mid to late week as a large upper ridge of high pressure builds over the central continent allowing hot air from the United States to flow north. Temperatures over 30C are likely by the weekend into next week along with increasing humidity levels that will likely send humidex values over 40C. There may be some scattered thunderstorm activity as we get into the building heat later this week, but overall hot and humid conditions are expected through the weekend with long range models hinting that the heat wave may continue through the middle of next week. So enjoy those comfortably cool temperatures while they last.. heat and humidity is on the way!
