The weather pattern remained active for the Southwest through the remainder of the month. Several smaller precipitation helped to boost total precipitation totals across Arizona. The largest and most widespread precipitation event occurred over January 21st to 23rd, when a strong and very wet storm system slowly moved across the Southwest. This was a classic El Nino type winter storm, fueled by a strong and extended subtropical jet stream across the Pacific Ocean. This system was able to tap into deep, subtropical moisture that sustained the long duration precipitation event. RainLoggers across Arizona reported precipitation totals of at least 0.5” over this period, but amounts were most impressive across southern Arizona. RainLoggers from Casa Grande to Arivaca reported multi-day totals exceeding 2.5”, with some reports topping 3” near Green Valley and Sahaurita.
