PHOENIX, AZ – The Valley wakes up to crisp desert air and clear skies this morning, the sun already glowing golden over Camelback Mountain. Early December starts calm and comfortable across central Arizona — a quiet stretch of warmth before midweek changes arrive.
According to the National Weather Service in Phoenix, high pressure will keep skies mostly sunny through Tuesday, with highs in the low 70s and cool nights dipping into the upper 40s to low 50s. Winds stay light and variable, ideal for commuters, outdoor markets, and early holiday prep.
By Wednesday, a weak Pacific system begins to edge inland, bringing a 30% chance of scattered showers late Wednesday night into Thursday morning. While totals are expected to stay light — likely under a tenth of an inch — any rainfall could briefly dampen I-10 and Loop 101 travel during early commutes. Skies will gradually clear again by Friday with mild conditions persisting into next weekend.
This pattern marks a classic early December setup for Phoenix — warm, dry afternoons giving way to cool, clear nights, a welcome reprieve before stronger winter systems begin shifting south later in the month.
