KAMLOOPS — High temperatures are returning to the Kamloops area once again.

In a public alert Tuesday (Aug. 16) morning, Environment Canada issued a heat warning for the North and South Thompson lasting from Wednesday (Aug. 17) until Friday (Aug. 19) morning.

According to the weather agency, a strong ridge of high pressure will bring a short heat wave to B.C. with daytime highs near 35 degrees and overnight lows near 15 in the North and South Thompson.

Speaking to CFJC Today, Environment Canada’s Doug Lundquist said the overnight lows could stay even warmer.

“We’re going to have about three hot days — from Tuesday here until Thursday — with highs in the 35, 36 degree range and overnight lows only 18,” said Lundquist. “That’s pretty normal for our summer but what isn’t is that we haven’t had the breaks when we get the high-20s.”

“We’re going to cool off on Friday here with a bit of an upper trough moving through our little system, but we’re only cooling down to 30 — and that’s the cold day. Then the ridge builds back in for next week.”

While extreme heat affects everyone, Environment Canada says the risks are greater for young children, pregnant women, older adults, people with chronic illnesses, and people working or exercising outdoors. Effects of heat illness include swelling, rash, cramps, fainting, heat exhaustion, heat stroke, and the worsening of some health conditions.

“When we get overnight lows in the 18-to-20-degree range, it’s too hot. Those who don’t have air conditioning can’t cool off. We do want to watch for the vulnerable in our lives. We saw that last year — though this is in no way as bad as last year.”

Residents are encouraged to drink plenty of water, plan outdoor activities during the coolest parts of the day, and seek cooler places such as shaded areas, swimming pools, or air-conditioned buildings.

The forecast is expected to change on Friday, when Lundquist predicts storm cells will move in.

“For Friday, that is a thunderstorm event,” said Lundquist. “We’re going to cool off from aloft. It’s going to stir the atmosphere. We’ll have showers and thunderstorms — maybe not as much as we had in the southwest Interior last weekend, in the sense that this might come more with dry lightning.”
