Arizona – Soft desert sunlight is spreading across Tucson this morning, but clouds are already building on the horizon. The day begins calm and mild, yet changing skies could bring rain and thunderstorms to southern Arizona later today.
Temperatures will climb quickly under morning sunshine, reaching around 79°F this afternoon across the Tucson metro. Drivers along Interstate 10 and the busy I-19 corridor will see dry pavement early, though conditions may change later in the day as clouds thicken.
According to the National Weather Service in Tucson, a 40 percent chance of showers and thunderstorms develops during the afternoon as moisture increases across southern Arizona. Winds remain light, but isolated storms could bring brief downpours and lightning.
Storm chances increase significantly tonight. Meteorologists now indicate a 90 percent chance of showers and thunderstorms after sunset. Some storms could produce bursts of moderate rainfall, briefly reducing visibility on major routes including I-10 and the Aviation Parkway corridor near Tucson International Airport.
Travelers should allow extra time if storms develop during the evening commute or for late-night arrivals into Tucson. Wet pavement and brief gusty winds may develop as storms pass through.
By Tuesday, the unsettled weather begins to fade. A lingering 40 percent chance of showers may persist early in the day, but skies gradually brighten through the afternoon.
Clear skies return midweek as sunshine dominates Wednesday. Temperatures climb again near 80°F, setting the stage for a strong warm-up heading into the latter half of the week.
By Thursday, Tucson pushes toward 89°F, bringing one of the warmest afternoons so far this March. That warmth will feel especially noticeable for spring break visitors exploring southern Arizona.
For now, keep an eye on the sky later today. Did rain reach your neighborhood this evening?
