Arizona wakes to a cool, calm desert morning as city lights fade under clear skies, but warmth arrives quickly once the sun climbs. Light winds and dry air signal a smooth start to a stretch that feels more like early spring than mid-winter.
According to the National Weather Service in Phoenix, temperatures rise steadily through the morning, climbing from the upper 40s to near 80 degrees this afternoon. Skies remain sunny across the Valley, with visibility clear and no travel disruptions expected along I-10, Loop 202, or surface roads.
Saturday night stays clear and mild, with lows near 50. By Sunday, sunshine dominates again as highs reach the low 80s. The warmth feels noticeable by midday, especially on pavement and south-facing neighborhoods.
Clouds increase slightly Sunday night, but dry conditions continue. Monday turns mostly sunny with highs near 79, keeping outdoor plans comfortable. Overnight lows dip into the low 50s, cool enough for open windows but far from winter cold.
By Tuesday, temperatures climb again, topping out near 81 under bright skies. The dry pattern shows no sign of breaking, reinforcing a prolonged stretch of above-normal warmth as February begins.
National outlooks show much of the western U.S. staying warmer than average into the first full week of February. Meanwhile, colder air remains locked east of the Rockies, sharpening the contrast across the country.
For Phoenix, the biggest concern isn’t storms but timing. Afternoon warmth fades quickly after sunset, and cooler nights follow fast. Plan layers if you’re out late, and stay hydrated during warmer afternoons. Are you adjusting plans for the sudden swing from chilly mornings to summerlike afternoons?
