Arizona – Cool desert air lingers at sunrise across southern Arizona, but warmth builds quickly as the sun climbs over the Catalina foothills. Jackets come off fast today as Tucson shifts into a springlike rhythm under clear skies.
According to the National Weather Service in Tucson, early temperatures settle in the low 40s before a rapid warmup pushes afternoon highs into the mid-70s. Winds remain light, keeping travel conditions calm across the metro area and along I-10 through Pima County. The dry air and bright sun make for ideal outdoor plans this MLK Day.
Clear skies continue tonight, allowing temperatures to dip back into the low 40s. Tuesday follows a similar pattern, starting cool and warming into the mid-70s again. Morning commuters may notice crisp air at sunrise, but no frost or freeze concerns are expected in the city.
By Wednesday, sunshine holds firm with highs remaining near 74 degrees. Mild afternoons and cool evenings dominate the midweek stretch, a sharp contrast to winter weather gripping much of the central and eastern U.S. For now, desert roads stay dry and visibility remains excellent.
Late week brings subtle changes. Clouds increase Thursday, and by Friday, a weak system may introduce a slight chance of showers. Any rain looks spotty and light, but slick pavement could briefly impact evening travel if showers develop. Temperatures ease slightly by the weekend, though conditions remain mild for January.
Longer-range outlooks suggest above-normal temperatures persist across the Southwest, while colder air continues to press east of the Rockies. Tucson stays on the warm side of the pattern, at least for now.
Heading out early today? Enjoy the cool start, stay hydrated this afternoon, and plan layers for the evening cooldown. Feeling the temperature swing where you live? Let us know how warm it gets in your neighborhood.
