FORECAST DISCUSSION

Winter officially arrived at 3:44 AM today. A pair of Winter storms are poised to follow the solstice.

Low pressure off Baja California supplies scattered showers today. Rain chances increase from 30% this afternoon to 100% late tonight through early Thursday afternoon. A few thunderstorms can’t be ruled out tomorrow across southern Arizona. Due to the warm nature of this storm system, snow levels hover around 8,000 feet.

Friday serves as a break between storm systems, although a stray shower can’t be ruled out. A cold front crashes into the state from the Pacific Northwest by Christmas weekend. Scattered showers are possible late Saturday afternoon, followed by widespread showers & snow above 4,000 feet Christmas Eve. Showers & low elevation snow tapers off by Christmas morning.

Between the two storm systems, valley floors could pick up 1-2″ rain by Christmas Day. A dusting to 1″ of snow can’t be ruled out for portions of Santa Cruz & Cochise Counties by Christmas morning. 10-20″ snow is possible above 7,000 feet, including Mount Lemmon and the White Mountains.
