High temperatures will reach 105-110°F today, which is around 5 degrees above normal for this time of year. This will result in widespread Moderate HeatRisk. An Extreme Heat Warning remains in effect through this evening for much of south-central Arizona.
An approaching weather system will lead to increasing winds across the region for the end of the week with the strongest winds, sustained 15-25 mph and gusting upwards of 25-35 mph, are expected today and Saturday. Combined with very dry conditions in place, this will lead to widespread elevated and locally critical fire weather conditions focused primarily over the higher terrain north and east of Phoenix. A Red Flag Warning has been issued for these areas.
Temperatures today will lead to widespread Moderate HeatRisk before cooling down several degrees over the weekend as a low pressure system moves into the West. This will drop the HeatRisk to Minor, as well as bring breezier conditions to the region. Everyone, especially those particularly sensitive to the heat, should take the necessary precautions to avoid heat-related illnesses.
Know the signs of heat exhaustion and heat stroke. If you have any of these symptoms, make sure to act quickly to prevent heat illness.
