PHOENIX — Extreme heat continues to grip the Valley!

An Extreme Heat Warning remains in effect for central and western Arizona through Tuesday evening and for the Grand Canyon below 4,000 feet through Thursday evening.

A Heat Advisory is also in place for the Northwest Plateau of Mohave County today and tomorrow.

With the extreme heat in place, we remain in ABC15 Weather Action Mode through Tuesday to remind you to take precautions and protect yourself, your family, and your pets.

Avoid contact with hot surfaces such as car doors, steering wheels, and playground equipment, as they can cause serious burns within seconds.

Isolated showers and thunderstorms will develop today along the Mogollon Rim, but the Valley will stay dry through tomorrow.

By midweek, the monsoon ridge will shift into a more favorable position to pull in additional moisture, increasing storm chances.

The best chance for storms in the Valley will come from Thursday through the early part of the weekend.

Stay tuned for updates as the forecast changes.
