Overview
- An approaching low will move in Thursday into Friday, with the best window for rain from Friday through the weekend along with gusty winds and falling temperatures.
- Forecast guidance centers on roughly 0.5 to 1.0 inch of rain across metro Phoenix, a significant share of typical November totals after an already wetter-than-normal fall.
- Snow is possible in the high country with snow levels near 7,500 to 9,000 feet, and only a few flakes are currently expected around Flagstaff.
- Forecasters note remaining uncertainty in exact timing and amounts, including whether the system taps atmospheric-river moisture that would enhance rainfall.
- ABC15 has declared Saturday and Sunday Weather Action Days, and ADOT is urging travelers heading north to prepare for winter driving and to avoid stopping on highway shoulders.
