Arizona — Early sunlight spills across the Valley this morning, warming rooftops and dry pavement after a cool desert night. The air feels calm and comfortable now, but subtle changes are already lining up to bring a different feel by the weekend.
According to the National Weather Service in Phoenix, temperatures climb into the low 70s today and Thursday as clouds gradually increase. Winds stay light, keeping travel and outdoor plans in good shape through the end of the workweek. Moisture begins edging closer by Friday, bringing the first hint of rain.
By Friday afternoon, a slight chance of showers develops across Phoenix and nearby communities, including Tempe, Glendale, and Mesa. Rain chances increase Friday night, with scattered showers possible into Saturday. While rainfall amounts remain light, slick roads could briefly slow traffic along I-10, Loop 101, and surface streets during passing showers.
Saturday brings the most noticeable shift. Daytime highs cool into the mid to upper 60s, clouds thicken, and showers become more likely, especially during the afternoon. Keep umbrellas ready if you’re heading to outdoor events or traveling around the Valley. Conditions improve gradually Saturday night as showers taper.
Sunday turns drier and brighter. Sunshine returns, winds stay light, and temperatures rebound into the upper 60s. It feels cooler than earlier in the week, but still seasonable for late January.
Looking ahead, the 6–10 day outlook favors above-normal temperatures across the Southwest. That suggests Phoenix could return to warmer, drier conditions early next week, even as colder air and higher precipitation focus across the central and eastern United States.
