Spring Climate Summary

Widely scattered showers and thunderstorms will develop this afternoon through early this evening, mostly in the White Mountains and over other other mountain tops and ridges of southeast AZ, including parts of southern Gila County. Rainfall potential will be limited, however, lightning strikes could lead to new fire starts in remote, higher terrain areas, and strong, gusty outflow winds are expected with any thunderstorms that do develop.

HeatRisk will reach the Moderate category across the lower deserts beginning Wednesday as high temperatures approach 4-6 degrees above normal. Make sure to practice smart heat safety.

Isolated showers and storms will develop this afternoon and tomorrow afternoon, mainly across high terrain of southeast AZ. High temperatures across the lower deserts will increase to 102-109 degrees, or around 5-8 degrees above daily normals through the rest of the workweek. This will result in HeatRisk increasing to the Moderate category. Temperatures will decrease closer to normal by this weekend. Increased breezy to locally windy conditions will develop late week through this weekend, which will combine with very dry conditions to heighten fire danger.

May of 2026 experienced on average above normal high and low temperatures, resulting in above normal mean temperatures for the month for the three climate sites (Phoenix, Yuma, and El Centro).

Spring of 2026 was the hottest meteorological Spring on record for the three climate sites (Phoenix, Yuma, and El Centro) and most of the region, largely driven by the historic March heat. It was also a very dry Spring.
