Phoenix is waking up to mostly clear skies and temperatures near 97°F Monday morning, but the real headline is the afternoon furnace: a high near 113°F and a heat index as high as 114°F. The dangerous heat will continue into Tuesday, keeping outdoor plans firmly in the “think twice” category.
An Extreme Heat Warning remains in effect for the Phoenix metropolitan area through 8 p.m. Tuesday. The National Weather Service says afternoon temperatures will generally run from 110°F to 115°F, with Major to Extreme HeatRisk expected across the lower deserts.
Heat Eases Slightly But Stays Dangerous
Monday night will remain mostly clear with a low around 91°F, while Tuesday should reach 111°F with a heat index near 114°F. Temperatures dip slightly Wednesday, Thursday and Friday, but highs will still range from about 109°F to 110°F, with humidity pushing afternoon heat indexes back toward 110°F to 115°F.
Gusty Winds And Blowing Dust Possible
Westerly winds will pick up Monday afternoon, reaching around 15 mph, with stronger gusts possible later in the day. A storm-related outflow could push into Maricopa and Pinal counties Monday evening, bringing gusts of 35 mph or more and a chance for blowing dust that could quickly reduce visibility.
Showers and thunderstorms are unlikely in the Phoenix metro area but cannot be ruled out late Monday night. The forecast keeps slight storm chances around Thursday and Friday evenings, rising to about 20% Saturday and 50% Sunday, with rainfall amounts expected to stay below a tenth of an inch where storms develop.
Heat Safety Remains The Priority
The National Weather Service recommends postponing strenuous outdoor activity until early morning or evening, drinking plenty of water and taking frequent breaks in shaded or air-conditioned spaces. Anyone showing signs of heat stroke should be moved to a cool location and treated as a medical emergency by calling 911.
Maricopa County residents can call 2-1-1 for information about free cooling centers, transportation and water assistance, according to the warning. More local heat resources are available through Maricopa County.
