Tucson, AZ – Midweek storms could disrupt travel and outdoor activities across southern Arizona on Wednesday as the National Weather Service projects a 40% chance of showers and thunderstorms after 11 a.m. Highs near 105°F and gusty, variable winds will add to the heat risk before storms develop.
According to the National Weather Service in Tucson, storms may begin forming late morning, with the greatest impacts likely in metro Tucson, Oro Valley, and along I-10 through Pima County. Lightning, localized downpours, and brief wind gusts could make for hazardous driving, especially during the evening commute. Residents should secure outdoor items and monitor for sudden storm development.
This midweek storm pattern may ease slightly Thursday but will not end entirely, with rain chances remaining at 40% through Thursday evening. Storm activity could return again Friday with a 50% chance of showers and thunderstorms, keeping afternoons unsettled and muggy.
While mornings will start dry and hot, storm timing means outdoor workers, hikers, and event planners should target early hours to avoid the afternoon lightning threat. Conditions remain storm-prone into the weekend, with updates expected daily.
