Comments:
During the morning hours, a strong, but somewhat moisture starved, low pressure system moved down from the NW toward the valley. During the morning, as the system moved through the high country in northern Arizona, some locations received a decent amount of snowfall for May (see below for snowfall totals). During the late morning through mid afternoon hours, the low pressure system moved almost directly over the valley. With strong dynamics associated with this system and a slight increase in moisture, some showers and thunderstorms developed across the region. The high rainfall total observed in the valley, was in Carefree Ranch, with 0.31in. of rainfall being recorded. During the late afternoon/evening hours the low quickly moved off to the east, resulting in a decrease in rainfall threats. While this system did not bring much rainfall to the valley, it did break the 80 day long streak of no measurable rainfall being recorded at our location, with the last time we recorded rainfall being on February 22nd.
