SoCal's heat wave to continue into the weekend. When will it start to cool down?

LOS ANGELES (KABC) -- Hot temperatures return this weekend as Southern California's heat wave continues, but some relief is on its way.

An excessive heat warning is in effect for a large swath of the region through Monday evening. Cooler weather is expected by Tuesday, and temperatures will then gradually start to drop.

Los Angeles and Orange counties this weekend can expect hot and sunny days, with a high around 90 degrees. By the middle of next week, temperatures will be in the mid-80s.

The valleys and Inland Empire on Saturday and Sunday will be just above 100. The break from the heat comes early next week, but temperatures will still be in the 90s.

If you're looking to beat the heat, the beaches on Saturday will reach a high of 76. Similar conditions are on tap on Sunday.

Mountains will be sunny and warm, with a high of 80 and temperatures around 48 overnight.

The desert areas can expect triple-digit heat this weekend, and Palm Springs could get as hot as 112. A slight cooling comes Tuesday.
