Back into the heatwave

Rob Gibson

The August long is in the rear-view mirror and while we may have had a small reprieve from the heat last week, don't turn the air conditioning down just yet.

Environment Canada has issued a special weather statement in effect for:

  •         Central Okanagan - including Kelowna
  •         North Okanagan - including Vernon
  •         South Okanagan - including Penticton

The mercury is set to soar by mid-week over the southern interior as a strengthening ridge of high pressure draws hot air up from the western U.S.

High temperatures will reach the low thirties and creep up another degree or two Tuesday, by Wednesday and Thursday daytime maximums will peak in the mid to high thirties with the potential for some communities to reach the 40-degree mark; overnight lows will only drop to the upper teens to about twenty degrees.

Heat Warnings may be issued later this week for some interior communities.

Cooling is expected to begin Friday.

There is also a special air quality statement in effect for the South Okanagan.

People with pre-existing health conditions, the elderly, infants, children and sensitive individuals are more likely to experience health effects from smoke exposure.

Environment Canada meteorologist Matt MacDonald tells Castanet the smoke may actually be helping to keep things cooler.

"Shortwave radiation coming from the sun gets filtered by the smoke so it reduces the daytime heating, but at night the earth radiates heat, giving it off if you will, and the smoke allows that out. So it keeps the daytime highs down and keeps the nights cooler."
