Following minimal rain earlier in the week and a significant chance of showers post-holiday, residents are advised to stay vigilant against heat-related illnesses.

Phoenix – The Labor Day weekend forecast for the metro Phoenix area predicts hot and mostly dry weather, with high temperatures expected to range from 104 to 110 degrees through Labor Day Monday. This is significantly above the typical peak temperature for the end of August, which is usually around 104 degrees.
The National Weather Service indicates that no rain is anticipated in the Valley until Monday evening, with only a 20% chance of precipitation. However, the likelihood of showers and thunderstorms is expected to rise after the holiday weekend, particularly with moisture beginning to return to the state.
On Friday, some areas in the Valley experienced brief popup showers, which brought less than 0.1 inches of rain to the majority of locations. East Mesa recorded a more significant amount, with reports of over 0.3 inches in certain spots. At Phoenix Sky Harbor International Airport, 0.01 inches of rain were logged early Friday, reflecting minimal precipitation levels, especially considering that since the monsoon season began on June 15, only 0.5 inches of rain has fallen at the airport. This total is over an inch below the normal amount for late August.
This weekend, temperatures are expected to peak at around 107 degrees on Saturday, 109 degrees on Sunday, and return to 107 degrees again on Monday. As these temperatures rise above average, the heat risk is classified as moderate. Such conditions make it crucial for residents to remain vigilant against heat-related illnesses.
A ridge of high pressure is responsible for these warmer-than-normal temperatures across the region. Residents should be aware that Maricopa County has an Ozone High Pollution Advisory in effect, which remains valid through Sunday. The Arizona Department of Health Services has outlined precautions to prevent heat exhaustion and heat stroke, especially during this extended period of high temperatures.
Motorists are also urged to exercise caution on the roads, as the heat can lead to vehicle breakdowns. Ensuring that cars are in good condition can help mitigate potential traffic delays caused by heat emergencies.
Looking ahead, light rainfall is a possibility for the higher terrain in eastern Arizona as early as Sunday evening. After Labor Day, there appears to be a 20% chance of rain on Tuesday and Wednesday, which is projected to increase to nearly 30% by Thursday evening. As the week progresses, temperatures are anticipated to cool slightly, with highs dropping to around 100 degrees by the latter half of the week and even reaching the upper 90s by Friday evening.
For residents who experienced severe weather earlier in the week, which included destructive thunderstorms and dust storms, the current weather forecast offers respite, but it also emphasizes the importance of preparation and awareness regarding hazardous weather conditions. The potential return of monsoon moisture midweek presents an opportunity for localized rain, offering a glimpse of relief from the ongoing high temperatures.
