Phoenix, Arizona – Hot weather is making a comeback in the Valley this week after a notably cool weekend. The high temperature is expected to reach 94 degrees today, which is around the normal average for this time of year in Phoenix. Morning temperatures will stay comfortable in the 60s and 70s.
As the week progresses, temperatures could climb even higher, possibly reaching near 100 degrees by Wednesday, Thursday, and Friday, largely due to a ridge of high pressure settling over the area. However, forecasters predict that this high pressure will begin to weaken as a low pressure system approaches from the west, bringing along some tropical moisture from Hurricane Priscilla.
Hurricane Priscilla, currently a significant weather system, is expected to weaken by the end of the week, but it will still contribute tropical moisture into Arizona’s weather patterns. Rain chances will start at approximately 20% on Thursday, and are anticipated to rise to 30% on Friday and Saturday. The forecast indicates that heavy rain is possible, which may lead to localized flash flooding and potential thunderstorms in various areas.
Despite the chance for rain, forecasters note that there remains some uncertainty regarding the amounts of precipitation expected, as well as the timing and overall likelihood of rain. If rain does come through, temperatures might drop slightly, resulting in highs in the 80s and 90s over the weekend. Morning lows for Thursday and Friday are projected to be in the upper 70s to around 80 degrees.
As the weekend nears, rain chances could continue to increase, potentially reaching 20% on both Saturday and Sunday, depending on interactions between a disturbance moving in from the West Coast and the remnants of Hurricane Priscilla.
This year’s rainfall data shows that Sky Harbor has recorded a total of 4.23 inches of rain thus far in 2025, which is -1.23 inches below the average for the year. Furthermore, the new average monsoon rainfall for Phoenix has decreased to 2.43 inches from the previous average of 2.71 inches, based on data from 1991-2020. Similarly, the average yearly rainfall in Phoenix has also dropped to 7.22 inches from 8.03 inches, reflecting changes observed from 1981-2010.
Residents of Phoenix are encouraged to stay informed about the weather changes, especially as potential storms could affect weekend plans, bringing much-needed moisture to the dry region. As the week unfolds, keeping an eye on local forecasts will be crucial for a safe and comfortable experience amidst rising temperatures and the possibility of rain.
