Phoenix is heading into a dangerously hot Thursday, with temperatures expected to climb from around 88 degrees before sunrise to 108 by late afternoon. The heat index could reach 110, and an Extreme Heat Warning is in effect across the Phoenix metropolitan area through 8 p.m. Thursday.
Dangerous Heat Peaks Thursday Afternoon
The forecast calls for sunny skies and mostly light west winds as temperatures move past 100 degrees around midday. The National Weather Service expects the hottest stretch between roughly 2 p.m. and 6 p.m., when heat-related illness can develop quickly during outdoor work, exercise, or errands.
Lingering dust and haze from an overnight outflow could briefly reduce visibility around sunrise before improving through the morning, according to the National Weather Service Phoenix office. Residents should consider moving strenuous activities to the early morning or evening, drink plenty of water, and watch for signs of heat exhaustion or heat stroke.
Friday Eases Slightly, But The Weekend Stays Hot
Friday will be sunny with a high near 105 and an overnight low around 86. There is a slight chance of showers or thunderstorms late Friday night, although the better storm chances are expected over Arizona’s higher terrain rather than the Phoenix low desert.
Saturday should reach 104 under mostly sunny skies, while Sunday will also top out near 104 with a slight chance of showers and thunderstorms after 5 p.m. The chance of storms increases somewhat Sunday night into Monday, but any rain in Phoenix remains uncertain and could be limited.
Cooling Trend Arrives Next Week
Monday is forecast to reach 105 before temperatures ease to about 101 Tuesday and 100 Wednesday. The weather service expects readings to move closer to normal by Tuesday, though the longer-range forecast remains less certain.
People without reliable air conditioning can call 2-1-1 for information about cooling centers, transportation, water, and other heat-relief resources. Maricopa County’s heat-relief guide also lists options available across the Valley through the hot-weather season.
