Temperatures in the Desert Southwest will stay near normal through Thursday, with highs reaching the upper 70s to low 80s in Phoenix. However, expect a sharp change in weather this weekend. A Pacific trough will bring cooler air starting Friday, with temperatures dropping to the low 70s across the lower deserts. Breezy conditions, particularly in southeast California and Arizona’s high terrain, are also forecast. While there’s a slight chance of precipitation in the higher elevations, the fast-moving low-pressure system may limit moisture, keeping rain chances minimal for most of the region.
By the weekend, temperatures will drop to the low 70s, and while some moisture could bring slight precipitation to the region, it’s expected to remain minimal. Look for temperatures to gradually warm up again by next week.
