Friday, July 10, Phoenix woke up already sweating, with mostly clear skies and temperatures pushing close to 90°F before many people had even poured their first cup of coffee. The valley is in for another punishing day, with afternoon highs expected to reach about 111°F. Overnight lows in the upper 80s will not offer much relief either, so anyone without solid air conditioning should anticipate very little cooling and shift strenuous plans to the earliest or latest hours of the day.
An Extreme Heat Warning is in effect through 8 p.m. MST Friday, with heat index values that could climb as high as 110 and conditions that significantly raise the risk of heat-related illness across the metro. Outdoor workers are urged to rearrange heavy tasks for early morning or evening and take frequent breaks, according to NWS Phoenix.
Where To Find Relief
Maricopa County operates a Heat Relief Network that includes cooling centers, hydration stations and partner sites across the region. Residents can call 2-1-1 to locate nearby options and get help with transportation and water. People without air conditioning are strongly encouraged to use these locations during extreme heat, per Maricopa County.
Weekend Outlook And Storm Chances
Temperatures dip only slightly on Saturday, with highs still near 109°F, before the monsoon pattern edges back in on Sunday. Late-day showers and thunderstorms are possible from Sunday evening into Monday, with about a 50% chance across the valley. Any storms that do pop up could bring brief heavy downpours and gusty outflow winds, but most spots are expected to see only light rainfall totals, according to NWS Phoenix.
Practical Safety Tips
Stay on top of hydration by drinking water often, avoid heavy exertion in the middle of the day, check on elderly neighbors and never leave children or pets in parked cars. If someone shows signs of heat stroke such as confusion, fainting, a rapid heartbeat or a very high body temperature, move them to a cooler place and call 911 right away.
