Tucson, AZ – Arizona’s spring sun returns in full force Thursday as Tucson braces for 90°F heat, marking the warmest day of the week. With dry air, clear skies, and rising temperatures, southern Arizona residents are urged to stay hydrated and monitor fire risks, especially near dry brush along I-10.
According to the National Weather Service in Tucson, Thursday’s high will reach near 90°F with clear skies and calm, dry winds from the northwest. The warmth, coupled with single-digit humidity levels, increases fire danger across Pima County and the surrounding desert zones. Overnight lows will dip to a mild 56°F, offering limited relief.
Light winds between 5 and 10 mph are expected Thursday afternoon, tapering into the evening. Conditions remain mostly clear through the weekend, with no precipitation forecast. Tucson drivers along I-10 should remain alert for visibility issues caused by blowing dust and dry conditions, particularly near open desert areas.
Friday brings another warm day with a high of 88°F. Saturday and Sunday stay sunny, with highs in the low to mid-80s—ideal for outdoor plans, but fire safety remains a concern. Overnight lows drop into the upper 40s and low 50s through the weekend.

- Friday: Mostly clear, high 88°F
