Triple-digit temperatures will arrive in parts of Southern California on Wednesday as a heat wave descends, exacerbating the woes of firefighters who already are batting a number of wildfires across the region. The spike in heat is expected to peak Thursday and taper down by Friday evening, forecasters say.

A significant warm-up is coming to much of Southern California with triple-digit heat expected to scorch parts of the valleys and Inland Empire. Temperatures will remain normal through Tuesday with a gradual increase on Wednesday.

After a cooler than normal start to summer, temperatures are finally heating up as we get the month of August started.
