Phoenix, Ariz. – Drivers and residents across the Phoenix metro should prepare for a double punch of triple-digit heat and possible afternoon storms Saturday. Dangerous conditions could develop quickly, especially for those traveling along Interstate 10, as intense heat mixes with isolated thunderstorm activity.
According to the National Weather Service in Phoenix, temperatures will climb to 103°F to 104°F Saturday afternoon, with heat index values peaking near 105°F. A slight chance of showers and thunderstorms lingers into late morning, then again by mid-afternoon, potentially producing brief heavy rain, gusty winds, and localized flooding. Officials advise avoiding flooded roadways and securing outdoor items ahead of any storms.
Thunderstorm winds could briefly drop visibility, posing a hazard for drivers on I-10 and Loop 202. If you’re traveling, keep an eye on rapidly changing skies and allow extra time. Heat remains a major concern—limit outdoor activities during peak hours and stay hydrated.
By Sunday, sunny skies return, with highs near 103°F and calmer winds. Monday and Tuesday bring hotter conditions, with highs pushing 106°F and continued low humidity. The next storm chance comes midweek, offering only limited relief from the August heat.
Warnings and advisories could be issued again if storm activity strengthens Saturday afternoon. Keep updated through local alerts and avoid unnecessary travel during peak storm times.
