Phoenix gets a brief morning breather Thursday after overnight storms and gusty outflows, but the Valley’s heat is already lining up a comeback. Skies are mostly clear around dawn with temperatures near 82 degrees, followed by mostly sunny conditions and an afternoon high near 107. The National Weather Service expects the heat index to reach as high as 111.
Wednesday’s storms brought 50-to-60-mph wind gusts across much of the metro, with a few reports near 65 mph. A few lingering showers or thunderstorms could persist around sunrise Thursday, but conditions should turn much quieter through the afternoon, according to the National Weather Service.
Triple-Digit Heat Builds Back Friday
An Extreme Heat Warning remains in effect for the Phoenix metropolitan area through 8 p.m. Sunday, with afternoon temperatures expected to reach 105 to 112 degrees. Friday will be sunny and hotter, with a high near 110 and an overnight low around 88.
Saturday could be the hottest day of the weekend, reaching about 111 degrees, with a slight chance of showers and thunderstorms after 5 p.m. Sunday should remain mostly sunny with a high near 110, while Monday through Wednesday will continue the relentless run of highs near 109 to 111 degrees.
Storm Chances Stay Limited In The Valley
Thunderstorm chances drop sharply Friday and Saturday as drier air moves into the lower deserts. The best odds will favor higher terrain areas, although an outflow from distant storms could still bring a sudden wind shift or isolated shower to parts of the Valley.
