July Climate Summary

A complex of strong thunderstorms will develop across SE AZ Monday afternoon and evening. This complex of thunderstorms is expected to fall apart in SE AZ, however, it will send a strong outflow boundary into south-central and SW AZ Monday night. The main hazards will be strong gusty winds (> 35 mph) and areas of blowing dust. Rain chances for the lower deserts is < 10%. Additionally, isolated to scattered showers and thunderstorms are expected across Gila County Monday afternoon and evening.

Well above normal temperatures with scattered areas of Major to Extreme HeatRisk is expected again Today. Temperatures will cool slightly through the first half of the week, but still remain above normal. Additionally, increasing moisture tonight into tomorrow will lead to increasing "feels like" temperatures. Lower desert locations will have "feels like" temperatures in the range of 110-120°, with the highest reading across SE CA and SW AZ. Storm chances will be mainly confined to the higher terrain areas of eastern and southeastern AZ through the majority of this week. Storm chances will increase across the lower deserts by the end of this week, with better chances heading into this weekend.

Extreme Heat Warnings have been extended through Tuesday for a good portion of the area as areas of Major HeatRisk will linger through at least Tuesday. High temperatures today and Monday will still easily exceed 110°F across the lower deserts, but some gradual cooling will occur over the next several days. Although daytime temperatures will start to go down, moisture and humidity will increase likely leaving it to feel just as hot through at least Tuesday.

Dangerously hot temperatures are in the forecast through the weekend. Learn to recognize the signs of heat-related illness before they happen, and don't underestimate the heat! It is the deadliest weather-related phenomenon.

All three official climate sites (Phoenix, Yuma, and El Centro) had above average temperatures & below normal precipitation this July. This July was also the 5th hottest on record for both Yuma and El Centro and was the 6th hottest on record for Phoenix.
