Arizona wakes up to crisp 58-degree air and pale blue skies, but the desert heat is already lining up for a rapid climb. Light winds drift across Sky Harbor this morning, and pavement warms quickly under full sun. By midafternoon, thermometers surge into the mid-80s across the Valley, setting the tone for a steady warming trend that peaks later this week.
According to the National Weather Service in Phoenix, highs reach 85 degrees today with calm winds turning west near 5 mph. Humidity sits near 40 percent early, keeping the air dry and comfortable. Clear skies dominate through Thursday, when temperatures push 91 degrees. By Friday and Saturday, Phoenix approaches 93 to 94 degrees under uninterrupted sunshine.
Statewide, above-average warmth stretches from Yuma to Flagstaff. While the High Country stays cooler, even northern Arizona trends milder by midweek. No rain is expected, and breezes remain light, reducing travel impacts. Still, large day-to-night temperature swings near 30 degrees could trigger isolated slick spots in shaded desert roadways during early morning hours where irrigation runoff lingers. Drive cautiously before 9 a.m., especially on elevated ramps.
Looking ahead, the warming trend expands into early next week. Long-range outlooks favor above-normal temperatures through the 6–10 day window, signaling early spring vibes across the Southwest.
Five Day Outlook for Phoenix, Arizona:
Today: Sunny, high 85.
Wednesday: Sunny, high 87.
Thursday: Sunny, high 91.
Friday: Sunny, high 93.
Saturday: Sunny, high 93 to 94.
