Heat pushes temperatures close to or in the 30s in B.C. before it cools off
Parts of B.C. are basking in a late-summer heat wave just days before the official start of fall this week, with temperatures approaching or even hitting the 30-degree mark, but it is expected to be short-lived as cooler and wetter weather is expected for the weekend
A multi-day heat event is in progress across B.C’s valleys this week, with temperatures already approaching, reaching or even surpassing the 30-degree mark before the fall season arrives.
The stretch of warm weather won't last too long, and is forecast to peak by Thursday, ahead of fall's arrival, which will be accompanied by cooler and wetter weather for some.

The South Coast region won't be as hot, and will be closer to seasonal or a few degrees above seasonal, but it will still see a very nice stretch of weather. However, the miniature heat wave will be short-lived as temperatures will drop on the weekend, with a bout of rainfall for many areas, too.
Late-summer heat wave before the arrival of fall
More 30-degree days are possible through this week in B.C. under a mid- to late-September heat wave.
On Wednesday, the coast will be cooler thanks to an onshore flow expected to settle temperatures closer to seasonal, but that is not the case for the valleys.
Heat and sunny skies in the valleys will persist through the week and into the weekend. The Osoyoos will have the multi-day opportunity to see 30-degree readings through Saturday. Meanwhile, the normal for this time of the year is 20°C.
So far, it has had 66 30-degree days this year. There have only been a handful of dates of recorded 30°C readings on or after Sept. 20 in Kamloops (nine to be exact). The most recent occurred on Sept. 24, 2011, and the latest took place on Oct. 8, 1911.
The heat is anticipated to peak Thursday with a forecast of 31°C.
However, the start of the rainy season is in sight. It may miss the Interior, but it will offer cooler, more seasonal temperatures in the long-range.
Widespread rain is expected to develop for the South Coast region this weekend as a system tracks in. A wetter-than-normal pattern is expected for the final week of September with a few systems tracking into the region, bringing the potential for heavy rain and cooler but seasonal temperatures.
