Saturday, July 11, 2026, Phoenix woke up warm and is marching straight toward another scorching afternoon. Phoenix Sky Harbor (KPHX) started the day near 91°F, and the high is projected to top out near 109°F later in the day. Overnight lows are expected to linger in the upper 80s, leaving little nighttime relief for outdoor workers or anyone without air conditioning.
Evening Gusts and Blowing Dust
Thunderstorms bubbling up over northern Sonora are expected to shove a northwestward outflow into south-central Arizona Saturday evening, kicking up gusts that could reach 30-40 mph and pockets of blowing dust. A Blowing Dust Advisory is in effect for Pinal and southern Maricopa counties from 6 p.m. to 10 p.m. MST on Saturday, July 11, with visibility briefly dropping below one mile and sudden wind shifts making driving tricky in spots. For the latest watches and short-term changes, keep an eye on the National Weather Service.
Thunderstorm Chances Sunday And Next Week
Monsoonal moisture ramps up on Sunday, July 12, boosting the chances for showers and thunderstorms over the lower deserts by late afternoon and evening. Forecast guidance points to roughly a 50% chance of storms Sunday night, with heat-index values climbing as high as 111°F. Any storms that do fire could bring strong outflow winds, brief heavy rain and localized dust. Elevated thunderstorm chances stick around through much of next week, which should keep day-to-day storm coverage variable and offer only spotty breaks from the hottest afternoons.
Heat Relief And Safety
With highs locked in the mid- to upper-100s, the usual heat rules still apply: drink plenty of water, avoid hard outdoor work during peak afternoon hours, and check on older neighbors and anyone working outside. If you do not have reliable air conditioning, the City of Phoenix maintains a list of cooling centers, hydration stations and other heat-relief resources, and 2-1-1 can help arrange transportation or locate nearby sites. Check the City of Phoenix for specific locations and hours.
Plan outdoor errands for the morning, secure anything that could turn into a projectile with those sudden evening gusts, and stay tuned to local alerts in case conditions change overnight. Drivers should be ready for abrupt wind shifts and pockets of reduced visibility on some Valley freeways Saturday evening.
