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 are in effect through Sunday across lower deserts locations as localized major HeatRisk continues. Cooler temperatures midweek will climb again by the weekend. Increased humidities will make it feel even hotter.
Dangerously hot temperatures are in the forecast through the weekend. Make sure to take the proper precautions to protect yourself from the heat, it is the deadliest weather-related phenomenon.
All three official climate sites (Phoenix, Yuma, and El Centro) had above average temperatures with near to below normal precipitation this July. This July was the 5th hottest on record for both Yuma and El Centro and the 6th hottest on record for Phoenix.
