Phoenix Faces Flash Flood Watch This Weekend
Residents across the Phoenix metro area should prepare for two distinct waves of precipitation this weekend as a strong storm system tracks in from the Pacific Northwest. According to reporting from AZ Family, the region is under a Flash Flood Watch, with meteorologists anticipating between 1 to 2 inches of rain across the Valley through Sunday. While this system lacks the severe intensity of last week’s weather—which included confirmed tornado activity—the primary concern remains the potential for flash flooding as multiple rounds of rain saturate the state.
The First Wave: Friday Morning Showers
The initial phase of this storm system is expected to arrive Friday morning. Forecasters anticipate a day characterized by scattered showers and thunderstorms, with the possibility of locally heavy downpours. While the atmospheric setup is not currently projected to reach the severity of recent events, authorities have not ruled out the possibility of severe storm development during the day. By Friday evening, the first wave is expected to exit, offering a brief window of relatively quiet conditions heading into Saturday afternoon.

Rainfall Intensifies on Halloween Night and Sunday
The reprieve on Saturday will be short-lived, as a second, more potent wave of moisture is expected to move into the area as early as Halloween night. The precipitation is expected to intensify overnight, lasting throughout the day on Sunday. Current projections indicate that Sunday will likely see more significant rainfall than Friday, with scattered showers and embedded thunderstorms expected to impact much of the state.
The temperature outlook for the weekend reflects this unsettled pattern. Highs will generally hover in the 70s, though there is a possibility that Sunday’s temperatures could struggle to climb out of the 60s depending on the density of cloud cover and the timing of the rainfall.
Residents Should Monitor Weather Updates Through Sunday
For the Phoenix metro area, a 1-2 inch rainfall event through Sunday is associated with a Flash Flood Watch.
The shift from a warm, dry environment to a multi-day wetting event shows why residents should monitor weather updates through the weekend, particularly as the Sunday forecast becomes clearer.
