TUCSON, Ariz. — A soft golden sunrise washes over the Catalina foothills this early Wednesday, signaling another calm, warm desert day. The air feels mild, still, and dry — but a slow fade from near-record November warmth is coming by week’s end.

According to the National Weather Service in Tucson, steady sunshine will dominate through Friday as highs hover in the upper 80s. Light south winds each afternoon will shift slightly northwest by late Thursday as cooler, drier air slides down from the Great Basin. By Friday, highs will ease closer to the mid-80s, marking the start of a comfortable Veterans Day weekend across southern Arizona.

Travelers on I-10 and I-19 will find ideal driving conditions, with no rain or wind hazards expected through early next week. The clear stretch offers excellent conditions for outdoor events, home projects, or early holiday decorating before the first stronger cold front of mid-November arrives. Lows will settle into the mid-50s under crisp, starry skies — enough to feel that slow seasonal turn without losing the desert’s daytime warmth.

For now, Tucson remains one of the warmest metros in the country, a contrast to the growing Arctic chill building from the Midwest to the East Coast. That colder air will eventually creep westward later this month, signaling the first true taste of winter for Arizona’s higher terrain. Until then, southern Arizona stays comfortably dry — a picture-perfect finish to the first full week of November.
