Following a weekend of boiling temperatures, the city will see another three days of sizzling heat.
Overnight low temperatures are expected to be in the low 20s, with some rural areas dipping into the low teens — but no matter where you are in southwestern Ontario, there won’t be much — if any — relief from the heat.
A cold front passed through the region Monday afternoon, but we’ll still have to wait a few days before the sweltering heat dies down, said Weiqing Zhang, meteorologist with Environment Canada.
“People waking up Tuesday morning might feel a bit of relief from the extreme heat of the weekend, but it is only a short cooldown,” she said.
Humidex values are expected to make those temperatures feel like the low 40s.
Zhang says the heat has stuck around for so long because the weather pattern isn’t moving.
The week-long heat wave started Friday and is forecast to last until the end of the week.
“On Thursday an active cold front will pass and it will replace the hot and humid air with cooler temperatures,” said Zhang.
Meanwhile, the the Middlesex-London Health Unit (MLHU) has prolonged their extended heat warning.
The initial warning was issued from Friday June 29 until Tuesday July 3, but officials say the warning will continue until the overnight low temperatures drop below 20 C Thursday.
“Extended periods of heat and humidity like we’ve seen over the weekend and are expecting over the next few days can be especially challenging for seniors, young children and those with medical conditions that put them at greater risk,” said Randy Walker, public health inspector with MLHU.
“We recommend people take steps to keep themselves cool; that means drinking plenty of water, limiting outdoor physical activity and maybe spending some time at a local pool or splash pad,” he said.
Symptoms of heat-related illness include rapid breathing, weakness or fainting, headaches, and confusion. If you experience any of those symptoms seek help from a relative, friends or doctor.
