Phoenix, AZ – Extreme Heat Warnings remain in effect across metro Phoenix through Tuesday, with daytime highs expected to reach 110–112°F. First Alert Weather Days have been declared, urging residents to take extra precautions in the dangerous conditions.
Heat Holds Through Tuesday
The heat wave will continue to grip the Valley through Tuesday before conditions begin to shift. By Wednesday, temperatures are expected to break slightly as moisture moves into Arizona, setting the stage for possible late-week storms.
Unusual Weather Pattern for August
Meteorologists note that the upper-level weather pattern is unusual for the middle of August. This year’s monsoon flow has yet to develop in its typical form, leaving much of the Valley dry.
If rain does arrive later this week, it will likely happen in a nontraditional monsoon fashion. A trough of low pressure pushing south from the Pacific Northwest is expected to pull moisture into the state, increasing storm chances — particularly in mountain regions.
Limited Rainfall Window
The Valley will likely see only a 48-hour window for rain, and even then, rainfall totals are expected to be light. Once the trough passes, conditions will quickly dry out, and temperatures will climb again heading into next week, according to AZFamily.
This year’s weather has some forecasters questioning whether 2025 will be another “non-soon”, a term used to describe monsoon seasons with minimal rainfall in Arizona’s desert regions.
Heat Safety Precautions
With temperatures above 110°F, heat-related illnesses can set in quickly. Officials recommend:
- Drinking plenty of water throughout the day
- Avoiding strenuous outdoor activity between 10 a.m. and 6 p.m.
- Wearing light-colored, loose-fitting clothing
- Checking on neighbors, the elderly, and pets
- Never leaving children or animals in parked vehicles
Symptoms of heat exhaustion include dizziness, rapid heartbeat, headache, and nausea. If symptoms worsen or include confusion or unconsciousness, call 911 immediately.
Looking Ahead
While the midweek moisture will offer some relief from the heat, it will be short-lived. By the weekend, Arizona is expected to return to dry, hot conditions, with temperatures once again climbing toward triple digits.
