by Phoenix, AZ — The National Weather Service has issued an Extreme Heat Warning for Phoenix and other parts of southern Arizona, with dangerously high temperatures forecast through Friday. Residents are being urged to take precautions as the region enters one of its hottest stretches of the summer.
Record Heat Already Setting In
On Saturday, Phoenix temperatures soared to 114°F, setting a new daily record high. Sunday followed closely behind with highs near 112°F, and the heat shows no sign of letting up.

Officials are warning that heat-related illnesses are likely if residents do not take proper safety measures.
