Phoenix is starting Monday, October 12, under mostly cloudy skies, with southeast winds early veering south by midmorning. Showers and thunderstorms are possible through the day, while a cooler stretch takes over Tuesday and Wednesday.
Storm Chances Build Through Monday Night
The National Weather Service in Phoenix calls for a 50% chance of showers and thunderstorms Monday, with lower-desert temperatures struggling to top 80 degrees. South winds around 10 mph could gust as high as 25 mph, and most lower-desert neighborhoods should see little rain, though brief heavier bursts remain possible.
A broken line of showers is possible this evening into tonight, with storm chances improving Monday night. The overnight low should reach about 66 degrees, with rainfall generally staying below a tenth of an inch in the lower desert.
Tuesday Brings A Quick Cooldown
Tuesday could start with a few lingering rain showers before 8 a.m., then turn mostly sunny with a high near 77. The latest forecast sharpens the timing of that shift from Hoodline's Sunday outlook, which had already flagged another round of Monday storms.
Tuesday night looks mostly clear and noticeably cooler, with temperatures falling to around 58 degrees. Wednesday should stay sunny with another high near 77, offering Phoenix a rare two-day break from both triple-digit heat and storm clouds.
Sunny Skies Return Before Late-Week Wind
Dry weather settles in Wednesday, with dry conditions continuing late in the week and highs in the 80s. East winds become more noticeable Thursday night through Saturday, with gusts potentially reaching 25 to 35 mph, while rain chances remain near zero.
For Monday, drivers and anyone with outdoor plans should be ready for changing skies, sudden downpours and gusty winds before the cooler, calmer pattern arrives.
