Seven-day forecast for Phoenix is all triple digits

Posted: Updated:

PHOENIX -- For the first time this year, the seven-day forecast is all triple digits.

We're looking at an even 100 degrees for a high today under mostly sunny skies.

We'll top out tomorrow at an above-average 103, but the mercury won't stop there. Plan on highs of 109 on Sunday and 110 on Monday.

While the National Weather Service has not issued a heat watch or warning for the Valley yet, it is a possibility.

The Yuma sector of the Border Patrol has issued a heat advisory for the Arizona-Mexico border.
