Phoenix is jumping the gun on summer, with sunny skies set to drive Friday afternoon highs close to 101°F and overnight lows only dipping to around 68°F. Midday humidity will be very low, so the air will feel harsher than the number on the thermometer and keep a streak of above-normal warmth going that could challenge late-March daily records.
Afternoon Winds Pick Up
Late tonight into Saturday morning, a tightening pressure gradient will kick up gusty easterly winds across the Valley and nearby higher terrain. Valley spots can expect gusts in the 25-30 mph range, while mountain peaks could see bursts over 40 mph. The strongest winds are expected after sunrise Saturday, easing gradually through the afternoon.
According to the National Weather Service, these gusts may create erratic outflow and leave outdoor conditions feeling unpredictable, especially in open areas and on higher terrain.
Heat Relief And Safety
The city’s Heat Relief Network is on standby with cooling centers, hydration stations and a downtown overnight respite site for anyone who needs a cooler place to be. If you work outside or rely heavily on air conditioning, try to move strenuous tasks to the morning or evening, drink water regularly and check in on older neighbors.
Locations, hours and updates are available from the City of Phoenix.
Short-Term Outlook
Sunday and Monday will stay warm, with highs in the mid-to-upper 90s, although increasing clouds and a small push of moisture should trim temperatures a few degrees by late weekend. Forecast models point to the best, though still limited, chance of showers from Tuesday night into Wednesday, with a more noticeable cool-down bringing highs back near the 80s by midweek.
Any rain that does develop is most likely over the higher terrain north and east of the Valley, while measurable rainfall in the lower deserts remains unlikely.
