Moisture creeping in from the southeast is set to bring a modest chance of showers and thunderstorms to Southern Arizona over the next few days. The highest probability of rainfall will be concentrated along the New Mexico border, while areas closer to Tucson will see only a slight possibility of precipitation by midweek.
Near normal start to the week, hotter days ahead
This Monday, June 23, temperatures across Southern Arizona will begin the week at near-normal levels, but conditions are expected to become noticeably warmer by the second half of the week.
Tucson will experience overnight lows around 70°F (21°C), while surrounding regions in Southern Arizona will generally dip into the mid to upper 60s°F (18–20°C).
By midweek, daytime highs will climb back into triple digits in Tucson, where the forecasted high temperature is 101°F (38°C). Neighboring locations will remain slightly cooler, with maximum temperatures mostly in the 90s°F (32–37°C) range.
Humidity and storm chances increase eastward
While the Tucson metro area may only experience limited storm activity, communities closer to the New Mexico border — including Willcox, Douglas, and Sierra Vista — will feel the impact of increasing moisture more directly. The southeast inflow brings not only higher humidity, but also the potential for isolated storms, particularly during the late afternoon and evening hours.
Stay tuned for further updates as the monsoonal pattern begins to shift and weather conditions evolve across Eastern and Southern Arizona.
