Arizona — Cool desert air settles quietly over Tucson this morning, crisp enough to see your breath at sunrise. That calm feel won’t last long. A wetter, more unsettled pattern is already lining up, and it will reshape the second half of the week.
Today stays bright and dry. Sunshine pushes temperatures into the mid-70s, a classic January warm-up that makes patios tempting by afternoon. Roads remain dry, and visibility stays high across I-10 and surface streets. Tonight turns cooler, slipping into the mid-40s under increasing cloud cover.
Clouds thicken Thursday, though daytime warmth holds. Highs again reach the mid-70s, but the air feels heavier by late day. According to National Weather Service guidance, moisture increases Thursday night, opening the door to scattered showers after sunset.
Conditions change noticeably Friday. Showers become likely, especially from late morning through the afternoon. Highs dip closer to 69 degrees, and pavement turns slick during heavier bursts. Drivers should plan extra time, particularly during peak travel hours.
Friday night stays active. Rain continues, with precipitation chances climbing toward 80 percent. Cooler air settles in, holding lows near the upper 40s. By Saturday, showers remain widespread, and daytime highs fall to around 59 degrees. While snow is not expected in Tucson, nearby higher elevations could see winter impacts.
Saturday night remains damp, and lingering showers may persist into early Sunday before gradually easing. For now, Sunday trends drier and slightly warmer, though confidence remains moderate.
Looking ahead, the 6–10 day outlook keeps the Southwest leaning above normal for temperatures, suggesting Tucson rebounds quickly after the weekend system exits.
