Arizona – Porch lights glow against a cool desert dawn in southern Arizona as Tucson starts the day in the low 40s. The air feels crisp now, but warmth builds quickly once the sun clears the Catalina foothills.
According to the National Weather Service, clear skies and light winds will allow temperatures to rise sharply today. Afternoon highs reach the low 70s, creating ideal driving conditions along I-10, I-19, and city arterials. Early commuters should still expect a noticeable chill before midmorning.
The warming trend accelerates into the weekend. Saturday brings abundant sunshine with highs climbing into the mid-70s. Dry air and calm winds dominate, keeping outdoor plans comfortable across Pima County. Hiking trails, golf courses, and neighborhood parks will see springlike conditions despite the calendar still reading January.
Sunday delivers the warmest stretch so far. Temperatures peak near 77 degrees under mostly sunny skies. Evening clouds drift in, but they won’t cool things down much. Overnight lows remain mild, settling near 49, which limits frost concerns in the metro area.
Monday continues the pattern with highs in the mid-70s and mostly sunny skies. Travel impacts remain minimal, and no precipitation is expected. By Tuesday, temperatures hold steady near 75, reinforcing the extended stretch of quiet winter weather.
This calm desert pattern stands in sharp contrast to dangerous cold and snow affecting large parts of the Midwest and East. While Arctic air grips other regions, southern Arizona remains on the warm side of the national setup for now.
Drivers should still be mindful of cool mornings followed by rapid afternoon warming, a combination that can affect tire pressure and visibility during sunrise hours.
