Phoenix got a brief pre-dawn sprinkle Saturday, but the Valley is still headed for a 102-degree afternoon. The latest forecast calls for mostly sunny skies, light winds and almost no chance of rain through the weekend, with even hotter temperatures arriving by Labor Day.
Saturday Starts With A Sprinkle, Then Heats Up
Phoenix Sky Harbor was reporting light rain and about 88 degrees shortly after 5:30 a.m. Saturday, though the shower activity should fade quickly as skies turn mostly sunny and temperatures climb to around 102. Winds will stay light, shifting from southerly to westerly later in the day, and Saturday night should remain partly cloudy with a low near 83.
The updated outlook is a meaningful shift from the previous forecast covered by Hoodline, with Sunday and Labor Day now trending a few degrees hotter. Sunday should reach 104 with gusts up to 20 mph, while Labor Day will be sunny and near 105.
Triple-Digit Heat Lingers Into Tuesday
Overnight temperatures will offer limited relief, staying around 83 to 85 degrees through Tuesday morning. Tuesday is currently expected to be the hottest day of the stretch, with a sunny high near 106 and only a slight chance of rain.
No watches, warnings or advisories are posted for the Phoenix area in the current forecast. Even so, the run of 100-degree afternoons makes morning and evening the better windows for errands, exercise and outdoor work.
Storm Chances Return Midweek
A slight chance of rain showers enters the forecast Tuesday night, followed by a 30% chance of showers and thunderstorms Wednesday afternoon and evening. Thursday carries a smaller 20% chance, and any new rainfall is expected to total less than a tenth of an inch.
People who need a break from the heat can use Phoenix's 24/7 heat-respite center at 20 W. Jackson Street, while the city also operates additional cooling and hydration sites. More information is available through the City of Phoenix.
